grounding instructions
WARNING!
Improperly connecting the grounding wire can result in the risk of electrical shock.
Check with a qualified electrician if you are in doubt as to whether the outlet is
properly grounded. Do not modify the plug provided with tool. Never remove the
grounding prong from the plug. If the cord or plug is damaged, have it repaired
before using. If the plug will not fit the outlet, have a proper outlet installed by a
qualified electrician. The Magforce must be plugged into an appropriate outlet,
properly installed and grounded in accordance with all codes and ordinances.
The plug and outlet should look like those in Figure A.
WARNING!
do not use slugger drilling machines on surfaces or materials being
welded. doing so can result in personal injury and/or damage to the
slugger drilling machine.
extension cords
Use only 3-wire extension cords that have 3-prong grounding-type plugs and 3-pole receptacles that accept the tool’s
plug. Replace or repair damaged cords. Make sure your extension cord is in good condition. When using an extension
cord, be sure to use one heavy enough to carry the current your product will draw. An undersized cord will cause a drop
in line voltage resulting in loss of power and overheating. Jancy recommends using a minimum 12 gauge extension cord
not to exceed 100 feet. The table below is supplied only as a guide to minimum gauge for extension cords, where the
smaller the gauge number, the heavier the cord.

drive handle. NOTE: Handle can be mounted on right or left side of machine.
what you should know before you drill
WARNING!
smart magnet function will strobe magnet lamp to indicate insufficient magnetic adhesion.
smart magnet no longer interrupts motor function!
1. 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, RPM, coolant and drilling time.
2. Remove any excessive mill scale or rust from surface to be drilled.
3. Material that has been flame cut may have become heat-treated and therefore difficult to drill. Avoid drilling
near such areas whenever possible.
4. Drilling with the Magforce in horizontal positions requires a special lubrication for Slugger cutters.
Consult Jancy Engineering for details.
5. Do not use Slugger drilling machines on surfaces or materials being welded.
Doing so can damage the machine’s electrical components.
7
before the cut
1. Select correct pilot pin and place in cutter shank from the rear, align flats on cutter shank with arbor body set
screws, insert cutter in arbor body.
2. Tighten set screws securely on cutter shank flats. NOTE: Set screws should be recessed in arbor body when tight.
3. The surface you are working on should be clean and flat, and free from rust, scale, dirt and chips.
4. Fill coolant reservoir with a water-soluble coolant.
5. Place Slugger machine on workpiece with pilot pin over the center of hole to be drilled.
6. Connect machine to power source.
7. Lower Slugger cutter to surface of material to be cut. Coolant will be released down the pilot into center of Slugger
cutter. Coolant flow can be stopped by lifting pilot pin off work surface.
CAUTION!
always use safety strap. failure to do so could result in personal injury
and/or damage to the slugger drilling machine.
8. The safety strap must be securely fastened to machine and around work being drilled. Loop strap around workpiece
and connect strap ends by attaching to D-rings on drill. Next, tighten safety strap by depressing thumb latch on cam
buckle and pulling flat end of safety strap until excess slack is removed. NOTE: Safety strap is intended only to restrain
the drill to the workpiece in the event of a power failure to the magnetic base.
9. Position chip guard toward work area before drilling.
ready to make the cut
CAUTION!
position chip guard toward work area before drilling.
1. Move magnet switch to “I” position to engage magnet. Red lamp will illuminate to indicate power is present.
Magnet base should be firmly secured to workpiece at this time. NOTE: Thin materials may require an additional
steel plate to achieve proper magnetic adhesion.
2. Start drill motor by depressing motor “I” button.
3. Using the feed handles, advance cutter into material until cutter has established an external groove in the material.
During the remainder of the cut, apply smooth, constant pressure without overloading motor. 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 shut motor off
and then 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.
after the cut
1. After 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.
2. Return machine into full upright position and depress red motor “O” button. Wait until motor completely stops.
3. Move magnet switch to “O” position when ready to release magnetic base from work surface.

basic troubleshooting
1. Magnetic base not holding securely
•Material is too thin to engage magnet.
•Surface of material being drilled must be free of chips, debris, rust and mill scale.
•Does size of cutter exceed machine’s rated capacity?
•Check magnet face for unevenness, nicks and burrs.
•Is welding equipment connected to material being drilled?
2. Drill motor running, arbor and spindle not turning
•Possible sheared spindle key.
3. Motor slows when drilling
•Is an extension cord being used? If so, see page 6 for recommended wire gages and cord lengths.
•Excessive downfeed pressure during drilling cycle will cause motor to slow and overheat.
•Does cutting tool need to be resharpened?
4. Coolant system not working
•Coolant system is gravity dependent, machine must be in a upright position to operate properly.
•Check coolant lines for blockage.
•Dirt or debris in coolant tank.
•Consistency of coolant mixture too thick.
•Is correct pilot pin being used?
•Vent hole in coolant tank lid blocked.
5. Slugs not ejecting from cutter
•Lack of coolant causing slugs to expand in cutter bore.
•Is correct pilot pin being used?
•Possible broken internal arbor parts.
6. Breaking cutters
•How is coolant being applied? 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.
7. Oversized or rough holes
•Insufficient coolant.
•Excessive feed pressure.
•Dull cutter.

regular maintenance
1. Adjust spoke handle tension according to user preference. The desired tension may be obtained by turning the set
screw, found on the front of the drill, left or right.
2. 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.
WARNING!
always remove cutter from drill before measuring runout.
never use hands or fingers to rotate arbor or motor spindle.
3. 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.
4. Inspect motor brushes and replace as needed during extended periods of heavy machine usage.
5. 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.
6. Regularly test machine by placing machine on non-ferrous material. Engage magnet switch. Magnet adhesion
warning lamp should flash.
