SAFETY RULES FOR CORDLESS LAWN MOWER

DANGER: This machine was built to be operated according to the rules for safe operation included in this manual. As with any type of power equipment, carelessness or error on the part of the operator can result in serious injury. This machine is capable of amputating hands and feet and throwing objects. Failure to observe all safety instructions could result in serious injury or death.

WARNING: When using electric lawn mowers, basic safety precautions should always be followed to reduce the risk of fire, electric shock, and personal injury. These basic precautions include the following:

CHILDREN 
Tragic accidents can occur if the operator is not alert to the presence of children. Children are often attracted to the mower and mowing activity. They do not understand the dangers. Never assume that children will remain where you last saw them.

• Keep children out of the mowing area and under the watchful care of a responsible adult other than the operator.
• Be alert and turn the mower off if a child enters the area.
• Use extreme care when approaching blind corners, doorways, shrubs, trees, or other objects that may obscure your vision of a child who may run into the mower.
• Never allow children under 14 years old to operate a power mower. Children 14 years old and over should read and understand the operation instructions and safety rules in this manual and should be trained and supervised by a parent. Only responsible individuals who are familiar with these rules of safe operation should be allowed to use this machine.

General Operation

• Read this operator's manual carefully in its entirety before attempting to assemble this machine. Read, understand, and follow all instructions on the machine and in the manuals before operation. Be completely familiar with the controls and proper use of this machine before operating it. Keep this manual in a safe place for future and regular reference and for ordering replacement parts.
• Use the right appliance - Do not use the lawn mower for any job except that for which it is intended. Your lawn mower has been designed to perform only one job: to mow grass.
• Don't overreach - Keep proper footing and balance at all times.
• Objects struck by the lawn mower blade can cause severe injuries to persons. The lawn should always be carefully examined and cleared of all objects prior to each mowing.
• Keep the area of operation clear of all persons, particularly small children, and pets.
• Before and while moving backwards with the mower, look behind and down for small children and other people.
• Keep clear of the discharge opening at all times.
• This machine is a precise piece of power equipment, not a plaything. Therefore, exercise extreme caution at all times. Your unit has been designed to perform one job: to mow grass. Do not use it for any other purpose.
• Don't force the lawn mower - it will do the job better and more safely at the rate for which it was designed.
• Thoroughly inspect the area where the equipment is to be used. Remove all stones, sticks, wire, toys and other foreign objects that could be tripped over or picked up and thrown by the blade. Thrown objects can cause serious personal injury.
• Plan your mowing pattern to avoid discharge of material toward roads, sidewalks, bystanders and the like. Also, avoid discharging material against walls or obstructions, which may cause discharged material to ricochet back toward the operator.
• To help avoid blade contact or an injury from thrown objects, stay in the operator zone behind the handles and keep children, bystanders, helpers, and pets at least 100 feet (30m) from the mower while it is in operation. Stop the machine if anyone enters the area.
• Always wear safety glasses or safety goggles during operation and while performing an adjustment or repair to protect your eyes. Thrown objects that ricochet can cause serious injury to the eyes. Always use a face or dust mask if the operation is dusty.
• Dress properly - Do not wear loose clothing or jewelry. They can be caught in moving parts. Use of rubber gloves and footwear is recommended when working outdoors. Wear sturdy, rough-soled work shoes and close-fitting slacks and shirts. Shirts and pants that cover the arms and legs and steel-toed shoes are recommended. Never operate this machine in bare feet, sandals, slippery or lightweight (e.g., canvas) shoes.
• Do not put hands or feet near rotating parts or under the cutting deck. Contact with the blade can amputate hands and feet.
• A missing or damaged discharge cover can cause blade contact or injuries from thrown objects.
• Many injuries occur as a result of the mower being pulled over the foot during a fall caused by slipping or tripping. Do not hold onto the mower if you are falling; immediately release the handle.
• Never pull the mower back toward you while you are walking. If you must back the mower away from a wall or obstruction, first look down and behind you to avoid tripping, and then follow these steps:
  • Step back from the mower to fully extend your arms.
  • Be sure you are well balanced with sure footing.
  • Pull the mower back slowly, no more than halfway toward you.
  • Repeat these steps as needed.
• Do not operate the mower while under the influence of alcohol or drugs.
• Stay alert - watch what you are doing. Use common sense. Do not operate the lawn mower when you are tired.
• The motor/blade control handle is a safety device. Never attempt to bypass its operation. Doing so makes the safety device inoperative and may result in personal injury through contact with the rotating blade. The motor/blade control handle must operate easily in both directions and automatically return to the disengaged position when released.
• Avoid dangerous environments - Don't use lawn mowers in damp or wet locations to avoid slipping and falling during operation.
• Always be sure of your footing. A slip and fall can cause serious personal injury. If you feel you are losing your footing, release the motor/blade control handle immediately and the blade will stop rotating within three seconds.
• Mow only in daylight or good artificial light. Walk, never run while operating.
• Stop the blade when crossing gravel drives, walks, or roads.
• If the equipment should start to vibrate abnormally, immediately stop the motor, remove the battery and check for the cause. Vibration is generally a warning of trouble.
• Before cleaning the machine, unclogging the chute or removing or replacing the grass bag, mulching insert, or side discharge chute, turn the motor off and wait until the blade comes to a complete stop, then remove the battery pack. The cutting blade continues to rotate for a few seconds after the motor is shut off. Never place any part of the body in the blade area until you are sure the blade has stopped rotating.
• Never operate the mower without the proper trailing shield, discharge cover, grass bag, mulching insert, side discharge chute, motor/blade control handle, or other safety protective devices in place and working. Never operate the mower with damaged safety devices. Failure to do so can result in personal injury.
• If situations occur that are not covered in this manual, use care and good judgment. Contact EGO Customer Service for assistance.
• Use only with the battery packs and chargers listed below:

  BA1120,BA1400,BA2240: CH2100 
  BA2800,BA4200: CH5500

OPERATION ON A SLOPE

Slopes are a major factor related to slip-and-fall accidents, which can result in severe injury. Operation on slopes requires extra caution. If you feel uneasy on a slope, do not mow it. For your safety, use the slope gauge on page 22 to measure slopes before operating this unit on a sloped or hilly area. If the slope is greater than 15 degrees, do not mow it.

Do

• Mow across the face of slopes; never mow up and down. Exercise extreme caution when changing direction on slopes.
• Watch for holes, ruts, rocks, hidden objects, or bumps which can cause you to slip or trip. Tall grass can hide obstacles.

Do not

• Do not mow near drop-offs, ditches, or embankments; you could lose your footing or balance.
• Do not mow slopes greater than 15 degrees, as shown on the slope gauge.
• Do not mow on wet grass. Unstable footing could cause slipping.

VARIABLE-SPEED SELF-PROPEL SYSTEM 

(only for LM2020SP)

The LM2020SP mower is equipped with variable-speed self-propel capability. This system is independent of the blade On-Off switch; it is not dependent on blade rotation. For example, when you have completed cutting your lawn, you can use the self-propel to propel the mower back to your storage location without blade rotation. Or you may choose to operate the mower as a non-self-propelled mower to maximize battery running time.

To operate the self-propel system without blade rotation

1. Pull the self-propel trigger to the handle.

2. To turn the self-propel off, release the self-propel trigger (Fig. 17).

   

The system has variable speed. To increase the speed, move the self-propel-speed-control lever forwards. To decrease the speed, move the self-propel-speed-control lever backwards.

To operate with the blade rotating for cutting

1. Depress the safety button.
2. With the safety button depressed, pull the bail switch upward to the handle and release the safety button.
3. Hold the bail switch against the handle with your left hand. Pull the self-propel trigger to the handle with your right hand.
4. With your right hand, hold both the bail switch and the self-propel trigger against the handle and use your left hand to adjust the self-propel-speed-control lever to choose the desired speed.

NOTICE: When you turn off the self-propel, for example, at the end of a row, it may become temporarily locked if you pull backwards on the mower. Simply push ahead slightly and then move the mower as required.

NOTICE: During cutting, at times it may be easier to mow around an object with the self-propel turned off.

WARNING: To reduce the risk of injury, never attempt to override the operation of the switch or self-propel system. Use the self-propel for its intended purpose only.

LED HEADLIGHTS 

The LED headlights are located on the front of the battery compartment.

• To turn on the lights, press the switch button (Fig. 19). The headlights provide bright light in front of the mower.

  

• To turn off the headlights, press the switch button again.

POWER INDICATOR ON THE MOWER

The mower is equipped with a power indicator to indicate the charge level of the battery pack and the working status of the mower. The power indicator will illuminate when the blade is rotating or when the LED headlights are turned on.

• The green light indicates that the battery pack is over 15% of its charge capacity.
• The red light indicates the battery pack's charge is low.

• The blinking red light indicates that the battery pack is nearly depleted and needs to be charged immediately.

  Power Indicator	Meaning	Action
  Shining green	Mower is working properly; battery has at least 15% of its charge.	n/a.
  Shining red	Low battery.	Stop the mower and charge the battery pack.
  Flashing red	The battery is nearly depleted.	Stop the mower and charge the battery pack.
  Shining orange	The mower stops due to overheating of the battery or mower overheated.	Remove the battery from the mower, move them to the shade and cool them at least 15 minutes.
  Flashing orange	The mower stops due to overload.	Remove the battery pack, check and clean if grass has collected beneath the deck. Slow down yourpace when cutting.

MOWER OVERLOAD PROTECTION

To prevent overload conditions, do not try to remove too much grass at one time. Slow down your cutting pace or raise the cut height. Your mower has built-in overload circuit protection. When the mower is overloaded, the motor will stop and the power indicator on the mower will flash orange. Remove the battery pack from the mower. Check to see if grass has collected beneath the deck and clear it if necessary, then install the battery and restart the mower.

BATTERY HIGH TEMPERATURE PROTECTION

The battery pack will generate heat during operation. The heat dissipates more slowly in hot weather. If the battery temperature exceeds 158° F (70°C) during operation, the protection circuit will immediately turn off the mower to protect the battery pack from heat damage. The power indicator on the mower will shine orange and the LED on the battery will flash orange. Release the bail handle, wait until the battery pack cools down to approximately 152°F (67°C), then restart the mower.

MOWING TIPS

NOTICE: A sharp blade will greatly enhance the performance of the mower, especially when cutting tall grass. Make sure to check the sharpness of the blade before mowing.

• Verify that the lawn is free of stones, sticks, wires, and other objects which could damage the lawn mower or motor. Such objects could be accidentally thrown by the mower in any direction and could cause serious personal injury to the operator and to others. WARNING: If you strike a foreign object, stop the motor and remove the battery. Thoroughly inspect the mower for any damage, and repair the damage before restarting and operating the mower. Excessive vibration of the mower during operation is an indication of damage. The unit should be promptly inspected and repaired.
• For best results, do not mow in circles. Travel back and forth across the lawn.
• When cutting thick grass, reduce your walking speed in order to allow for a more effective cut and a proper discharge of the clippings.
• To maintain a healthy lawn, cut off only one-third or less of the total length of the grass. The average lawn should be approximately 1-1/2 to 2 inches long during cool months, and between 2 to 3-1/4 inches long during hot months.

SLOPE GAUGE 

WARNING: Do not mow a slope that has an angle of greater than 15° (a rise of approximately 2-1/2' (0.75m) every 10' (3m)). Mow across the face of a slope and never up and down. Use Fig. 21 as a guide in order to identify slopes that cannot be mowed safely.

MULCHING TIPS

WARNING: Inspect the area where the mower is to be used and remove all stones, sticks, wire, and other debris that might be thrown by the rotating blade.

• Release the switch to turn off the mower blade rotation when crossing any graveled areas; stones can be thrown by a rotating blade.
• Set the mower to the highest cutting height when mowing on uneven ground or in tall growth.
• For effective mulching, do not cut wet grass; it tends to stick to the underside of the deck, preventing the proper mulching of grass clippings. The best time to mow grass is in the late afternoon, when the grass is dry and the newly cut area will not be exposed to direct sunlight.

• For the best mulching performance, set the cutting height to remove approximately one-third of the grass blade length, ideally no more than 1-1/2'' at one time. If the grass is overgrown, it may be necessary to increase the cut height to make it easier to mow and to prevent overloading the motor. Slow your cutting pace in tall or thick grass conditions. For mulching extremely thick or tall grass, it is advisable to first cut at a high cut-height setting, and then re-cut to the final cut height. Otherwise, make narrower cuts and mow slowly. ALWAYS MAKE SURE THAT THE BLADE IS SHARP.

MAINTENANCE

WARNING: To avoid serious personal injury, always remove the battery pack from the mower before cleaning or performing any maintenance. 

WARNING: When servicing, use only identical replacement parts. Use of any other parts may create a hazard or cause product damage. To ensure safety and reliability, all repairs should be performed by a qualified service technician.

CLEANING THE MOWER

WARNING: Always remove the battery pack when servicing or transporting the mower. The underside of the mower deck should be cleaned after each use, as grass clippings, leaves, dirt, and other debris will accumulate. This accumulation is undesirable, as it will promote rust and corrosion. Remove any build-up of grass and leaves on or around the drive shaft (LM2020SP only) and motor fan (do not use water). Wipe the mower clean with a damp cloth.

REMOVING THE BLADE

WARNING: Always protect your hands by wearing heavy gloves or wrapping the cutting edges with rags or other materials when performing any maintenance on the mower blade. Always remove the battery pack when servicing or transporting the mower. 

NOTICE: The following tools are required for replacing the blade:

• 9/16" (14mm) wrench
• Torque wrench
• Manual screwdriver or metal rod with a diameter of 5/16" (8mm)
• Manual screwdriver or metal rod with a diameter of 1/4" (6.35mm) or less.

1. Stop the motor; remove the battery pack from the mower.
2. Turn the mower on its side.

3. While wearing protective gloves, place a metal rod (e.g., a 3.5" length screw bit) with diameter less than 5/16" (8mm) into the fixing hole to act as a stabilizer. 
   NOTICE: If the bolt rotates with the motor shaft when loosening the bolt, turn the fan by hand to align the through holes in the fan with the holes in the blade, and place another metal rod (e.g., a 3.5" length screw bit) with diameter less than 1/4" (6.35mm) into the aligned holes to act as another stabilizer (Fig. 22).

   

4. Use a 9/16" (14mm) wrench to turn the blade bolt counterclockwise to loosen it.
5. Continue using the 9/16" (14mm) wrench to turn the blade bolt counterclockwise to loosen it completely.
6. While wearing protective gloves, remove the bolt, outer flange, and the blade (Fig. 23).

INSTALLING THE BLADE

WARNING: Always protect your hands by wearing heavy gloves or wrapping the cutting edges with rags or other materials when performing any maintenance on the mower blade. Always remove the battery pack when servicing or transporting the mower. 
NOTICE: To re-install or replace the blade, be sure to replace the parts in the exact order in which they were removed (Fig. 23).

1. Mount the inner flange to the fan (Fig. 24).

   

2. Mount the fan and the inner flange onto the motor shaft with the fan blade towards the deck (Fig. 25).

   

3. While wearing protective gloves, position the blade on the inner flange with the surface stating "THIS SIDE FACING GRASS" facing toward the outside (Fig. 26).

   

4. Align the outer flange with the shaft and assemble it in place.
5. Mount the bolt into the shaft and turn it clockwise by hand to pre-tighten it.

6. While still wearing protective gloves, hold the blade with one hand and turn the fan with the other hand to align the holes in the blade with the through holes in the inner flange (Fig. 27).

   

7. Place a metal rod (e.g., a 3.5" length screw bit) with diameter less than 1/4" (6.35mm) into the aligned holes to act as a stabilizer. Place another metal rod (e.g., a 3.5" length screw bit) with diameter less than 5/16" (8mm) into the fixing hole to act as another stabilizer (Fig. 28).

   

8. Use a 9/16" (14mm) torque wrench (not included) to tighten the bolt clockwise. The recommended torque for the blade bolt is 36-43 ft-lb (49-59Nm).

SHARPENING THE BLADE

WARNING: Always protect your hands by wearing heavy gloves or wrapping the cutting edges with rags or other materials when performing any maintenance on the mower blade. Always remove the battery pack when servicing or transporting the mower. 

WARNING: Use proper eye protection while removing, sharpening, and installing the blade. 

WARNING: A worn, cracked, or damaged blade can break and pieces of the damaged blade can become dangerous projectiles. Thrown objects can cause serious injury. Inspect the blade regularly and do not operate the mower with a worn or damaged blade. 

NOTICE: Keep the blade sharp for best mower performance. A dull blade does not cut grass cleanly or mulch properly. A dull blade can be sharpened, but a blade that is excessively worn, bent, cracked, or otherwise damaged must be replaced. A worn or damaged blade can break, causing blade pieces to be thrown from the mower.

If the blades are found to be bent, take the lawn mower to an authorized EGO service center for inspection.

Sharpening Frequency

Sharpening the blade twice during a mowing season is usually sufficient under normal circumstances. Sand causes the blade to dull quickly; if your lawn has sandy soil, more frequent sharpening may be required.

When Sharpening The Blade

• Make sure that the blade remains balanced.
• Sharpen the blade at the original cutting angle.
• Sharpen the cutting edges on both ends of the blade, removing an equal amount of material from each end.

To Sharpen Blade In A Vise

1. Remove the blade from the mower (please see REMOVING THE BLADE).

2. Secure the blade in a vise (Fig. 29).

   

3. Wear proper eye protection and gloves and be careful not to cut yourself.
4. Carefully file the cutting edges of the blade with a fine-tooth file or sharpening stone, maintaining the original cutting edge angle.

5. To check the blade balance: clamp a nail or a screwdriver with a round shank in the horizontal position. Position the blade so that the nail or round shank of the screwdriver supports the blade through its center hole. Balance the blade horizontally. If either end of the blade rotates downward, remove some metal from the heavy or lower end until the blade is balanced. It is balanced when neither end drops (Fig. 30).

   

6. Replace the blade on the mower and tighten it securely (please see INSTALLING THE BLADE).

WARNING: An unbalanced blade will cause excessive vibration when rotating at high speeds. It may cause damage to the mower and could break, causing personal injury.

LUBRICATION

Lubricate with light oil as directed below at least once each season.

• Periodically lubricate the spring and pivot pin in the quick-adjust lever, the torsion spring and pivot of the rear-discharge door with light oil to prevent rust (Fig. 31a & 31b).

  

• Place the mower into the locked storage position:
  1. Move the cutting-height adjustment lever toward the front and engage it in the lowest setting (setting 1).
  2. Open the handle-locking clamps and fully recess the side rails to the compact position.
  3. Press and hold the quick-adjust lever with your right hand to release the handle.
  4. Gently pivot the handle toward the front of the mower; release the quick-adjust lever and continue to pivot the handle until you hear and feel the lock pin engage in the locked storage position.

• Place the folded mower upright on the ground (Fig. 31c & 31d).

  

  

• Lubricate the deck-height adjustment joint.
• For LM2020SP, lubricate the bearings on the drive shaft near the rear wheels and the bearings in the front wheels (Fig. 31c).
• For LM2020, lubricate the bearings in both the rear and front wheels (Fig. 31d).

REPLACING THE WHEELS 

(Fig. 32a, 32b & 32c)

WARNING: Always remove the battery pack when servicing or transporting the mower.

1. Turn the mower on its side with the upper surface against a wall.
2. Use a flat blade screwdriver to pry the dust cover away from the wheel.
3. Use an adjustable or 1/2 inch (13mm) wrench to turn the bolt counterclockwise to loosen it.
4. Remove the bolt, the worn wheel, and the washer(s) from the wheel axle.

NOTICE: When replacing the rear wheel for the self-propelled mower (LM2020SP), remove the drive gear from the worn wheel and assemble it to the new wheel with the 3 screws.

1. Mount the washers and the new wheel on the wheel axle. Note that the round recess must face outward.
2. Lock the wheel with the bolt by tightening the bolt clockwise.
3. Mount the dust cover onto the wheel and press it in place.

REPLACING THE TRAILING SHIELD

WARNING: Always remove the battery pack when servicing or transporting the mower. 

WARNING: Never operate the mower unless the trailing shield is in place and working. Never operate the mower with damaged safety devices. Failure to do so can result in personal injury. The trailing shield is subject to wear and damage, which could expose moving parts or allow objects to be thrown. For safety protection, frequently check the trailing shield and replace it immediately with only the identical replacement part, listed in this manual.

1. Remove the battery.
2. Turn the mower on its side with the upper surface against a wall.
3. Remove the rear wheel on the top side, following the section "REPLACING THE WHEELS" in this manual.

4. For self-propelled mower LM2020SP, loosen the wheel cover locking screw and remove the screw, spring washer, and flat washer in that order, then remove the wheel cover from the wheel shaft (Fig. 33).

   

5. Repeat steps 1 to 3 above to remove the other rear wheel and wheel cover (LM2020SP only).

6. Loosen the locking screw for the trailing shield on both sides; remove the worn trailing shield and the flat washer. Save the washer for reassembly (Fig. 34a & 34b).

   

   

7. Replace with a new trailing shield and attach it with the two locking screws and flat washers.

8. Re-install the rear wheel covers (LM2020SP) and rear wheels; be sure to replace the parts in the exact order in which they were removed (Fig. 35a & Fig. 35b).

   

   

STORING THE MOWER

The following steps should be taken in order to prepare the lawn mower for storage.

1. Remove the battery pack from the mower and store it at room temperature in a dry location.
2. Clean the mower as described earlier in the maintenance section.
3. Inspect the blade and replace it or sharpen it if required.
4. Lubricate the mower.
5. Store the mower in a dry, clean location. Do not store it next to corrosive materials, such as fertilizer or rock salt.
6. Store the mower in a covered, enclosed space that is cool and dry and out of the reach of children.
7. Do not cover the lawn mower with a solid plastic sheet. Plastic coverings trap moisture around the mower, which causes rust and corrosion.

The handle assembly can be folded away completely for storage:

1. Remove the grass bag.
2. Move the cutting-height adjustment lever toward the front and engage it in the lowest setting (setting 1).
3. Open the handle-locking clamps and fully recess the side rails to the compact position.
4. Press and hold the quick-adjust lever with one hand to release the handle. Gently pivot the handle toward the front of the mower; release the quick-adjust lever and continue to pivot the handle until you hear and feel the lock pin engage in the locked storage position.

5. Store the mower upright or flat (Fig. 36a & 36b).

   

WARNING: If the mower tips over from the upright position, mower damage or personal injury may result. Always keep the mower stable and out of the reach of children when it is in the upright position. If possible, lay it flat for storage.
