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.
1. Work Area Safety
a) Keep work area clean and well lit. Cluttered or dark areas invite accidents.
b) 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.
c) Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.
d) 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.
2. Electrical safety
a) 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.
b) 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.
c) Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of
electric shock.
d) 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.
e) 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.
f) 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 or RCD reduces the risk of electric shock.
3. Personal safety
a) 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.
b) 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.
c) 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.

important safety instructions
d) 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.
e) Do not overreach. Keep proper footing and balance at all times. This enables better control of the power
tool in unexpected situations.
f) 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.
g) 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.
4. Power tool use and care
a) 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.
b) 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.
c) 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.
d) 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.
e) 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.
f) Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less
likely to bind and are easier to control.
g) 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.
h) 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.
5. Service
a) 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.

special instructions
1. If you require an additional manual, please contact Jancy Engineering at (563) 391-1300 for a FREE copy.
2. Never place hands, fingers, gloves or clothing near cutting area or rotating machine parts.
3. Always disconnect machine from power source before changing cutters, clearing chips, refilling lubricant or
performing adjustments.
4. Keep all safety features functioning and working properly.
5. Never wear loose clothing, gloves or jewelry when working near cutting area or rotating machine parts.
6. Always use eye and hearing protection.
7. Always use safety strap and chip guard provided with machine.
8. Always use proper tooling. Keep cutters securely fastened.
9. Do not use dull or broken cutters.
10. Do not use Slugger® drilling machines on surfaces or materials being welded. Doing so can damage the
machine’s electrical components.
11. Beware of slugs ejected at end of cut. They become HOT during the cut.
12. Magnet will not hold properly on thin materials or rough and dirty surfaces.
13. Keep bottom of magnet burr free and clear of chips and debris.
14. To reduce the risk of electrical shock, do not use machine in wet or damp areas.
15. Do not remove or alter electrical panels. Use only authorized service centers for repairs.
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 4x4 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.
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.
DRIP LOOP: To help prevent cutting fluids from traveling
along power cord and contacting power source, tie a drip
loop in power cord as shown in Figure B.

Refer to pages 7, 11 and 12. Assemble three spoke handles (item #22) to feed hub. NOTE: Feed hub assembly is
mounted on right side of machine frame–if necessary, it can be reversed for lefthand operation by simply removing the
fastener (item #24) and hub (item #21) from frame. Remove hub pinion shaft from right side of frame and insert it into
left side of frame. Replace hub and fastener into frame and tighten securely. Thread pipe handle into motor assembly
(item #5).
Install coolant bottle assembly (item #28) by sliding the bracket (included with assembly) onto 2 retaining screws (item
#27) located on the right side of the drill. Insert the hose connector into the fitting at the lower front of the gearcase.
what you should know before you drill
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 4x4 in horizontal positions requires a special lubrication for Slugger® cutters.
Consult Jancy Engineering for details.
5. The 4x4 is not designed for use on thin materials that will not hold magnet securely.
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 into 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 cutting fluid.
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. Once the pilot makes contact, coolant will be released down
the milled slot on the pilot and into the Slugger® cutter. Coolant flow can be stopped by lifting pilot pin off work
surface or shutting off coolant valve. NOTE: Be sure coolant valve is open. Regulate coolant flow by adjusting
coolant valve on coolant bottle.
8. 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. NOTE: Safety strap is intended only to restrain the drill to the
work piece 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!
positionchipguardtowardworkareabeforedrilling.
1. Move magnet switch to “ON” position. 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 backing plate to achieve
proper magnet adhesion.
2. Start drill motor by depressing green motor “ON” button.
3. Using the feed handles, advance cutter into material until Slugger® 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.
4. NOTE: This machine is equipped with motor overload protection circuitry. An overload indicator light will turn on if the motor load is excessive. If the motor load is increased beyond this point, the motor will shut off and the overload
indicator light will remain on. To restart the motor, first press the red motor “OFF” button. The overload light will turn
off, and the green motor “ON” button can now be pressed to restart the motor. See caution below.
1. After the Slugger® cutter has finished the cut, the “slug”, or uncut center portion of material, will be expelled when
the motor is returned to the full up position.
2. Return machine into full upright position and depress red motor “OFF” button, wait until motor completely stops.
3. Move magnet switch to “OFF” position when ready to release magnetic base from work surface.
4. Move magnet switch to “DEMAG” position for one or two seconds to reduce residual magnetism.

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.
•Size of cutter exceed machine’s rated capacity.
•Check magnet face for unevenness, nicks and burrs.
•Welding equipment connected to material being drilled.
•Dull cutter.
2. Drill motor running, arbor and spindle not turning
•Possible sheared spindle key.
3. Motor slows when drilling
•Refer to page 6 for recommended wire gages and cord lengths.
•Excessive downfeed pressure during drilling cycle will cause motor to slow and overheat.
•Cutting tool needs to be resharpened.
4. Coolant system not working
•Coolant system is gravity dependent. Machine must be in a upright position to operate properly.
•Check operation of coolant valve. Valve must turn freely.
•Check coolant lines for blockage.
•Dirt or debris in coolant tank.
•Consistency of coolant mixture too thick.
•Incorrect pilot pin being used.
•Vent hole in coolant tank lid blocked.
•Lid on too tight.
•Bottle pressurized.
5. 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.
6. 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.
•Improperly adjusted motor slide–see page 10.
7. Oversized or rough holes
•Insufficient coolant.
•Excessive feed pressure.
•Dull cutter.
•Motor slide improperly adjusted.

regular maintenance
1. The motor slide may require adjustment after machine has been in service. Loosen jam nuts using provided wrench.
Using feed handles, position motor/slide assembly in the full up position. Using supplied hex key, equally turn adjustment screws clockwise to increase slide tension or counterclockwise to decrease slide tension. Do not over tighten
adjustment screws. Excessive slide tension can damage the machine. Properly adjusted, the motor/slide assembly should have no side to side movement and remain positioned without drifting down.
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.
3. Periodically lubricate motor slide ways with lithium base grease.
4. Visually inspect arbor, sleeve and support bracket for wear.
5. 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.
6. Inspect coolant system, reservoir, o-rings, lip seals and coolant collar for wear.
7. Inspect motor brushes and replace as needed.
8. Replace any worn parts and regularly tighten fasteners that have become loose during usage.
9. Regularly test machine by placing machine on non-ferrous material. Engage magnet switch.
Motor should not start.
