Detailed Description

The mower uses a rechargeable battery to power a rotating cutting blade beneath the chassis. The 420 mm deck cuts a broad strip with each pass, while the rear grass box collects clippings during operation.

Main components include the chassis, upper and lower handles, locking handles, green start button, operating lever, safety key, battery housing, clear battery visor, protective rear flap, grass box, cutting-height lever, charger, and front carry handle.

A filling indicator flap shows when the grass box requires attention. When the flap closes, empty the box. An overfilled box can restrict the grass chute and reduce collection performance.

Safety

Read all instructions before using the CLM2.0 Cordless Lawn Mower and retain them for future reference. The rotating blade can cause severe injury, and it continues moving briefly after the motor is switched off.

• Use the mower only on grass and lawns. Do not operate it on gravel.
• Do not mow in rain, use the mower on wet grass, or leave it outdoors while raining.
• Keep children, animals, and bystanders away from the mowing area. The manual specifies a minimum safe distance of 5 metres for bystanders.
• Never allow children to operate the mower, and do not allow untrained adults to use it.
• Wear safety glasses, sturdy gloves, and non-slip safety footwear. Do not operate the mower barefoot or in open-toed shoes.
• Keep loose clothing, jewellery, hair, hands, and feet away from moving parts.
• Inspect the lawn and remove stones, sticks, and other objects that could be thrown or jam the blade.
• Check the blade, fasteners, grass box, guards, and protective flap for damage or excessive wear before each use.
• Do not operate the mower if a guard is damaged, the grass box is missing, or the product is incomplete or modified.
• Keep both hands correctly positioned on the handle during mowing.
• Start the mower only when your feet are safely away from the blade, and do not tilt the mower while starting it.
• Mow across slopes rather than directly up and down them. Use extra care on slippery ground, when changing direction, reversing, or pulling the mower towards you.
• Do not use the mower on excessively steep slopes.
• Stop immediately if the mower vibrates strongly, then identify the cause before continuing.
• Before leaving the mower, clearing a blockage, changing cutting height, emptying the grass box, carrying or tilting the mower, cleaning it, or performing maintenance, wait for the blade to stop and remove the safety key.
• Do not use the mower if the operating switch does not start or stop it correctly.
• Do not use the mower in explosive atmospheres or near flammable liquids, gases, or dust.
• Do not operate the mower during an approaching thunderstorm.

Battery and Charger Safety

• Use only the supplied battery pack and charger with this mower.
• Do not use the charger outdoors or in damp or wet conditions.
• Never handle the charger or mower with wet hands.
• Inspect the charger and power cables for damage or ageing before charging.
• Do not use a damaged charger, cover its ventilation slots, or attempt to open it.
• Charge only when the surrounding and battery temperature is between 0°C and 40°C.
• After heavy use or exposure to high temperatures, allow the battery and mower to cool for approximately 30 minutes before charging.
• Do not expose the battery to fire, excessive heat, direct sunlight for prolonged periods, or temperatures above 80°C.
• Do not burn, immerse, open, or dismantle the lithium-ion battery.
• If battery liquid contacts skin, wash immediately with soap and water. If it enters the eyes, rinse with cold water for at least 10 minutes and seek urgent medical attention.
• Disconnect the charger from the mains and battery once charging is complete.

Setup and Operation

Assemble the Handle

1. Position the upper handle so the green start button is at the top and the handle arms face away from you.
2. Align the upper handle inside the lower handle sections.
3. Pull each lower handle back until it clicks into position.
4. Place a securing washer over each supplied bolt with the flat side facing outward.
5. Insert the threaded inserts into the ends of the locking handles.
6. Align the upper and lower handle holes, then pass a bolt through each side.
7. Keep each locking handle straight while aligning it with its threaded insert.
8. Turn the locking handles to tighten them, then push them down towards the mower to lock the handle assembly.
9. Check that the handle is secure and does not move or feel loose.

Connect the Power Cables

1. Slide the cable collar over the power cables.
2. Align the keyway on the upper cable with the two openings on the lower cable.
3. Push the cables together until they lock.
4. Turn the collar clockwise until it is tight.

The cable connection is located below the left-side locking handle.

Assemble and Fit the Grass Box

1. Lock each edge of the metal frame into its corresponding retaining point.
2. Hook the base of the grass box over the frame.
3. Lower the frame towards the base until the box is fully supported.
4. Lift the mower’s rear protective flap.
5. Insert the grass box into the rear of the mower and ensure its hooks engage correctly.
6. Lower the protective flap into position.

Install the Battery and Safety Key

1. Lift the clear battery visor.
2. Place the battery into the housing with the “G” logo facing upwards.
3. Slide it into position until it clicks.
4. Check the charge indicator through the visor, then close the visor.
5. Rotate the safety key 90 degrees clockwise to activate the mower.

The mower will not operate without the safety key. Remove the key before maintenance, cleaning, clearing grass, carrying the mower, or placing your hands near the blade.

Start and Stop the Mower

1. Confirm that the battery is fitted, the grass box and protective guards are correctly installed, and the safety key is activated.
2. Press and hold the green safety button.
3. Pull the operating lever towards the handle to start the blade.
4. Release the safety button after the motor has activated.
5. Release the operating lever to stop the mower.

Keep your feet away from the blade when starting. After releasing the lever, wait for the blade to stop completely before approaching or handling the mower.

Adjust the Cutting Height

The CLM2.0 Cordless Lawn Mower provides six cutting-height settings: 30, 40, 50, 60, 70, and 80 mm.

1. Stop the mower completely and remove the safety key.
2. Hold the height-adjustment lever firmly.
3. Move the lever into the required notch.
4. Confirm that the lever is seated securely before mowing.

The 30 mm and 40 mm settings can scalp uneven lawns and make grass less resistant to wear and drought. For longer, uneven, or damp grass, choose a higher setting. Test an unfamiliar height on a small area first to avoid creating bald patches.

Mow and Empty the Grass Box

1. Start the mower and push it forward at a walking pace.
2. Watch the filling indicator flap during mowing.
3. When the flap closes, stop the mower and remove the safety key.
4. Lift the rear protective flap.
5. Grip the green handle on the grass box.
6. Lift and pull the box towards you.
7. Empty the clippings in a suitable location.
8. Check the chute and box before refitting the grass box.

If the grass box becomes overfilled, the grass chute may clog and the indicator flap can close. Do not clear a blockage until the blade has stopped and the safety key has been removed.

Battery Charge Indicators

Press the button on the rear of the battery to display its approximate state of charge. The illuminated LEDs indicate the remaining level:

• 100–60%
• 60–30%
• 30–10%
• 10–1%

Charge the Battery

1. Lift the battery visor.
2. Push the release latch below the visor.
3. Pull the battery out of the mower.
4. Place the battery on the charging stand with the “G” logo facing upwards.
5. Align the side runners with the charger rails and slide the battery into position.
6. A solid red charger light indicates that the charger is connected.
7. A flashing green light indicates that charging is in progress.
8. A solid green light indicates that charging is complete.

Charging takes approximately 1 hour under suitable conditions. Disconnect the charger from the mains and battery when charging has finished.

Carry the Mower

Before lifting or carrying the mower, release the operating lever, wait until the blade stops, and remove the safety key. Use the central carry handle and the hand-hold beneath the front of the mower.

Cleaning and Maintenance

Wear protective gloves whenever handling, cleaning, inspecting, or replacing the blade. Remove the safety key whenever the mower is not being used, transported, handled, or stored.

• Inspect the blade for looseness, damage, wear, and secure fasteners before use.
• Check visible screws, nuts, covers, guards, and other fittings regularly.
• After mowing, clean the cutting blade and apply lubricating oil or spray before storage.
• Wipe the mower with a dry cloth.
• Do not use water, solvents, polishes, or abrasive cleaning materials.
• Do not immerse the mower in water.
• Keep the grass box and chute clear so clippings can enter the box correctly.
• Do not attempt repairs to damaged parts unless qualified to do so.
• Use genuine replacement parts to maintain mower safety.
• Store the mower in a secure, dry place away from children and moisture.
• Do not keep the battery outdoors for prolonged periods during winter.

Battery Disposal

Do not place the lithium-ion battery in household waste, fire, or water. Recycle or dispose of it through an appropriate electrical-product recycling facility. Before disposal, discharge the battery by operating the mower, remove it from the housing, and cover its connections with heavy-duty insulating tape to help prevent short circuits. Do not open or dismantle the battery.

Warranty

The CLM2.0 Cordless Lawn Mower is covered against material and manufacturing faults for 2 years from the purchase date, or from delivery if delivery occurred later.

Warranty service requires proof of purchase or delivery. Repairs or replacement under the warranty do not extend the original warranty period, and replaced parts become the property of the manufacturer.

Coverage does not include normal wear and tear, accidental damage, negligent or careless use, misuse, unsuitable handling, use outside normal domestic garden purposes, unauthorised modifications, faulty installation, non-genuine parts or accessories, or repairs and alterations carried out by unauthorised parties. The warranty operates alongside statutory consumer rights.

Pros & Cons

• Pros: cordless 48 V operation, approximately one-hour charging time, broad 420 mm cutting width, six height settings, 50-litre collection box, removable battery, and a relatively light 13.5 kg design.
• Cons: the mower is intended for domestic use only, must not be used in rain or on wet grass, requires careful blade isolation before every maintenance task, and lower height settings may scalp uneven lawns.
