IMPORTANT SAFETY INSTRUCTIONS

WARNING!
WARNING Read all safety warnings and all instructions. Failure to follow the warnings and instructions may result in electric shock, fire and/or serious injury.

Save all warnings and instructions for future reference. The term "power tool" in the warnings refers to your mains-operated (corded) power tool or battery-operated (cordless) power tool.

Work Area Safety
1. Keep work area clean and well lit. Cluttered or dark areas invite accidents.
2. Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases or dust. Power tools create sparks which may ignite the dust or fumes.
3. Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.
4. Secure work. Use clamps or a vise to hold work. It’s safer than using your hand and it frees both hands to operate tool.
Electrical safety
1. Power tool plugs must match the outlet. Never modify the plug in any way. Do not use any adapter plugs with earthed (grounded) power tools. Unmodified plugs and matching outlets will reduce risk of electric shock.
2. Avoid body contact with earthed or grounded surfaces such as pipes, radiators, ranges and refrigerators. There is an increased risk of electric shock if your body is earthed or grounded.
3. Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.
4. Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the power tool. Keep cord away from heat, oil, sharp edges or moving parts. Damaged or entangled cords increase the risk of electric shock.
5. When operating a power tool outdoors, use an extension cord suitable for outdoor use. Use of a cord suitable for outdoor use reduces the risk of electric shock.
6. If operating a power tool in a damp location is unavoidable, use a ground fault circuit interrupter (GFCI) or residual current device (RCD) protected supply. Use of a GFCI ar RCD reduces the risk of electric shock.
Personal safety
1. Stay alert, watch what you are doing and use common sense when operating a power tool. Do not use a power tool while you are tired or under the influence of drugs, alcohol or medication. A moment of inattention while operating power tools may result in serious personal injury.
2. Use personal protective equipment. Always wear eye protection. Protective equipment such as dust masks, non-skid safety shoes, hard hats or hearing protection used for appropriate conditions will reduce personal injuries.
3. Prevent unintentional starting. Ensure the switch is in the “OFF” position before connecting to power source and/or battery pack, picking up or carrying the tool. Carrying power tools with your finger on the switch or energizing power tools that have the switch on invites accidents.
4. Remove any adjusting key or wrench before turning the power tool on. A wrench or key left attached to a rotating part of the power tool may result in personal injury.
5. Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations.
6. Dress properly. Do not wear loose clothing or jewelry. Keep your hair, clothing and gloves away from moving parts. Loose clothes, jewelry or long hair can be caught in moving parts.
7. If devices are provided for the connection of dust extraction and collection facilities, ensure these are connected and properly used. Use of dust collection can reduce dust-related hazards.
Power tool use and care
1. Do not force the power tool. Use the correct power tool for your application. The correct power tool will do the job better and safer at the rate for which it was designed.
2. Do not use the power tool if the switch does not turn it on and off. Any power tool that cannot be controlled with the switch is dangerous and must be repaired.
3. Disconnect the plug from the power source and/or the battery pack from the power tool before making any adjustments, changing accessories or storing power tools. Such preventative safety measures reduce the risk of starting the power tool accidentally.
4. Store idle power tools out of the reach of children and do not allow persons unfamiliar with the power tool or these instructions to operate power tool. Power tools are dangerous in the hands of untrained users.
5. Maintain power tools. Check for misalignment or binding of moving parts, breakage of parts and any other condition that may affect the power tool’s operation. If damaged, have the power tool repaired before use. Many accidents are caused by poorly maintained power tools.
6. Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.
7. Use the power tool, accessories and tools etc. in accordance with these instructions, taking into account the working conditions and the work to be performed. Use of the power tool for operations different from those intended could result in a hazardous situation.
8. Check for damaged parts. Before further use of the tool, a guard or other part that is damaged should be carefully checked to determine that it will operate properly and perform its intended function. Check alignment of moving parts, binding of parts, breakage of parts, mounting and any other conditions that may affect its operation. A guard or other part that is damaged should be properly repaired or replaced by an authorized service center.
Service
1. Have your power tool serviced by a qualified repair person using only identical replacement parts. This will ensure that the safety of the power tool is maintained.

WHAT YOU SHOULD KNOW BEFORE YOU DRILL

Type of material to be drilled, Brinnell or Rockwell hardness, material thickness and position should all be determined to ensure proper selection of Slugger cutting tools, coolant and drilling time.
Material that has been flame cut may have become heat-treated and therefore difficult to drill. Avoid drilling near such areas whenever possible.
Drilling with the Holemaker II in horizontal positions requires a special lubrication for Slugger cutters.
Our new Holemaker II incorporates state of the art design features such as our “SMART MAGNET ” circuitry. This feature does not allow the motor to operate in unsafe magnetic holding conditions. Illuminated on/off
switches indicate the existence of a sufficient magnetic field. If On/Off switches are not illuminated, there is not a proper magnetic field. When drilling materials under 3/8" thick, an additional steel plate may be required to achieve proper magnetic adhesion.
Remove any excessive mill scale or rust from surface to be drilled. Thin material, mill scale, rust, paint, existing holes, surface irregularities, coolant, chips and other factors could affect magnetic holding conditions.

BEFORE THE CUT

Select correct pilot pin (Table 1) and place in cutter shank from the rear, align flats on cutter shank with arbor body set screws, insert cutter in arbor body.
Tighten set screws securely on cutter shank flats.
NOTE: Set screws should be recessed in arbor body when tight.
The surface you are working on should be clean and flat, free from rust, scale, dirt and chips.
Place Slugger® machine on workpiece with pilot pin over the center of hole to be drilled. (Figure 2)
Connect machine to power source. (Figure 3)
Turn on coolant valve, located on left side of the frame. (Figure 4) Lower Slugger® cutter to surface of material to be cut.
NOTE: Coolant flow starts when pilot pin contacts work surface. Coolant flow can be stopped by lifting pilot pin off work surface or moving the valve to the "off" position.
CAUTION! ALWAYS USE SAFETY STRAP. FAILURE TO DO SO COULD RESULT IN PERSONAL INJURY AND/OR DAMAGE TO THE SLUGGER® DRILLING MACHINE.
The safety strap must be securely fastened to machine and around work being drilled. Loop strap around work piece and connect strap ends by attaching to D-rings on drill. (Figure 5)
NOTE: Safety strap is intended only to restrain the drill to the workpiece in the event of a power failure to the magnetic base.
Position chip guard toward work area before drilling. (Figure 6)

READY TO MAKE THE CUT

CAUTION!
CLOSE CHIP GUARD AND LOWER TO WORK SURFACE.

NOTE: IF ON/OFF SWITCHES ARE NOT ILLUMINATED, THERE IS NOT A PROPER MAGNETIC FIELD.

1. Move magnet switch to “ON” position. (Figure 7) Switch will illuminate to indicate power is present–magnetic base should be firmly secured to workpiece at this time. Thin materials may require an additional steel plate to achieve proper magnet adhesion.
Start drill motor by depressing green motor “ON” button. (Figure 8)
Using the feed handles, advance cutter into material until Slugger cutter has established an external groove in the material. During the remainder of cut, apply smooth constant pressure without overloading motor. (Figure 9)

NOTE: Slugger® cutters are designed for uninterrupted cutting. Chips are evacuated during the cut. Do not peck drill when using Slugger cutters.

CAUTION!
IF DRILL MOTOR SHOULD STALL OR STOP BEFORE A COMPLETE CUT IS MADE, ALWAYS REMOVE CUTTER FROM HOLE BEFORE ATTEMPTING TO RESTART MOTOR. FAILURE TO DO SO COULD RESULT IN PERSONAL INJURY AND/OR DAMAGE TO THE SLUGGER® DRILLING MACHINE. NOTE: THIS MACHINE’S STANDARD UNMODIFIED CIRCUITRY WILL AUTOMATICALLY SHUT THE DRILL MOTOR OFF IF MAGNETIC BASE IS SEPARATED FROM ITS WORK SURFACE. IF YOUR MACHINE REQUIRES ADJUSTMENT, CONTACT JANCY’S SERVICE DEPARTMENT.

AFTER THE CUT

CAUTION: THE SLUG WILL BE HOT AND HAVE SHARP EDGES.

After the Slugger® cutter has finished the cut, the “slug”, or uncut center portion of material, will be expelled when motor is returned to the full up position. (Figure 10)
Depress red motor “OFF” button. Wait until motor completely stops. (Figure 11)
Move magnet switch to “OFF” position when ready to release magnetic base from work surface. (Figure 12)
Residual magnetism may exist after magnet is turned off.

Setup Guide

To operate the Slugger Holemaker II,

Start by ensuring the magnetic base is securely attached to the metal surface.
Turn on the machine and adjust the speed according to the material being drilled. Align the annular cutter with the desired drilling spot and gradually lower it into position.
Apply gentle to moderate pressure depending on the material thickness. Once the hole is drilled, turn off the machine and carefully remove the cutter.
For assembly, ensure all parts are included and follow the manufacturer's instructions for attaching the annular cutters and other accessories.
Configuration involves setting the desired speed and ensuring proper alignment before each use.

Slugger Holemaker II Magnetic Drilling Machine MAINTENANCE

The rail system may require adjustment after machine has been in service. Using feed handles, position motor/slide assembly in the full up position. (Figure 13) Using supplied 3mm hex wrench, slightly turn the two M6 X 10 adjustment screws equally on each of the two guide rods clockwise to increase rail tension, or counterclockwise to decrease rail tension. (Figure 14) Again using feed handles, position motor/slide to down position and insure even adjustment throughout travel. Do not over tighten adjustment screws as excessive rail tension can damage the machine. Properly adjusted, the motor/slide assembly should have no side-to-side movement and will remain where positioned without drifting.
Keep bottom of magnet clean, free of chips, burrs, nicks, oil and other contaminants. Inspect magnet face to ensure surface is flat and square. A worn magnet surface dramatically reduces magnetic holding force. (Figure 15)
Periodically clean & lubricate motor slide rails. (Figure 16)
Visually inspect arbor, and support bracket for wear. (Figure 17)
Visually inspect arbor for excessive runout. Arbor runout should not exceed .0035 inches per revolution. This is most accurately measured by placing a dial indicator needle inside of arbor bore and rotating arbor while observing indicator.
NOTE: Always remove cutter from arbor body before measuring runout. Never use hands or fingers to rotate arbor or motor spindle.
Inspect motor brushes periodically and replace as needed. (Figure 18)
Replace any worn parts and regularly tighten fasteners that have become loose during usage.
NOTE: Never operate machine with worn or missing parts. Use only Jancy replacement parts.
Regularly test machine by placing on non-ferrous material to test “SMART MAGNET” circuitry. Engage magnet switch. On/off switches should not illuminate. Motor should not start when on button is pushed.

BASIC TROUBLESHOOTING

Magnetic base not holding securely
- Material is too thin to engage magnet properly.
- Surface of material being drilled must be free of chips, debris, rust and mill scale.
- Size of cutter exceeds machine’s rated capacity.
- Excessive downfeed pressure.
- Check magnet face for unevenness, nicks and burrs.
- Welding equipment connected to material being drilled.
Drill motor not running
- Insufficient magnetic field, "Smart Magnet" circuitry functioning properly.
- Check motor cord.
- Check magnet resistance.
Motor switches not illuminated
- Insufficient magnetic field, "Smart Magnet" circuitry functioning properly.
- Check switches for functionality.
Drill motor running, arbor and spindle not turning
- Possible sheared spindle key.
Motor slows when drilling
- If an extension cord is being used, see page 6 for recommended wire gauges and cord lengths.
- Excessive downfeed pressure during drilling cycle will cause motor to slow and overheat.
- Cutting tool needs to be resharpened.
Slugs not ejecting from cutter
- Lack of coolant causing slugs to expand in cutter bore.
- Incorrect pilot pin being used.
- Possible broken internal arbor parts.
Breaking cutters
- Coolant must be supplied to interior of cutter.
- Excessive feed pressure being applied when cutter initially contacts work surface.
- Confirm material hardness.
- Drilling stacked materials with incorrect cutter.
- Dull cutters; dull or chipped cutting edges require excessive feed pressure, resulting in breakage.
- Excessive arbor runout– see regular maintenance on page 10.
- Possible bent motor spindle or worn arbor sleeve.
- Improperly adjusted motor slide– see page 10.
Oversized or rough holes
- Insufficient coolant.
- Excessive feed pressure.
- Excessive cutter runout.
- Dull cutter.
- Worn support bracket roller bearing or arbor body sleeve.
- Bent motor spindle.
- Motor slide improperly adjusted.
