Important Safety Instructions

1. Read All Instructions

2. Grounding Instructions

This tool should be grounded while in use to protect the
operator from electric shock. The tool is equipped with
a 3-conductor cord and a 3-prong grounding type plug
to fit the proper grounding type receptacle. The green
(or green and yellow) conductor in the cord is the
grounding wire. Never connect the green (or green and
yellow) wire to a live terminal. Your unit is for use on
115V, and has a plug that looks like that shown in sketch
(A). An adapter, see sketches (B) and (C), is available
for connecting sketch (A) type plugs to 2-prong recep
tacles. The green-colored rigid ear, lug, or the like,
extending from the adapter must be connected to a
permanent ground, such as a properly grounded outlet
box.
Note: Use of a grounding adapter is prohibited in
Canada by Part I of the Canadian Electrical Code.

4. 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 the conductor size is large enough
to prevent excessive voltage drop which will cause
loss of power and possible motor damage.

5. Do Not Force Tool

It will do the job better and faster at the rate for which
it was intended.

6. Keep Work Area Clean

Cluttered areas and benches invite injuries.
Keep dirt and chips from under magnet and
Rotabroach Cutter area. Do not attach magnet to
surfaces where paint is thick or peeling.

7. Consider Work Area Environment

Do not expose tool to rain.
Do not use tool in damp or wet locations.
Keep work area well lit.
Do not use tool in presence of flammable liquids or
gases. Disconnect from power source when changing
cutters or maintaining drill.

8. Guard Against Electric Shock

Prevent body contact with grounded surfaces. For
example: pipes, radiators, ranges, refrigerator
enclosures.

3. Safe Electrical Connection

Your HMD100 is rated for use on 120VAC at 50-60Hz.

Do not attempt to use drill on power sources rated other
than this. Wet electrical connections are shock hazards.
To prevent the cutting fluid from traveling along the cord
and contacting the plug or power outlet, tie a drip loop
as shown above. Also elevate extension cords or gang
box connections.

9. Keep Children Away

Do not let visitors contact tool. All visitors should be
kept away from work area while in use.

10. Store Idle Tools

When not in use, tools should be stored in a dry, and
high or locked-up place — out of reach of children.

11. Use Right Tool

Do not force small tool or attachment to do the job
of a heavy duty tool.
Do not use tool for purpose not intended — for
example — do not use a circular saw for cutting tree
limbs or logs.

12. Secure Work

Use clamps or a vise to hold work. It is safer than
using your hand and it frees both hands to operate
tool.

13. Always Wear Safety Glasses or Goggles

14. Dress Properly

Do not wear loose clothing or jewelry. They might
entangle with spinning chips or get caught in moving
parts. Rubber gloves and non-skid footwear are
recommended when working outdoors. Wear sturdy
leather gloves when working indoors.
Wear protective hair covering to contain long hair.

Important Safety Instructions

(Continued)

15. Do Not Abuse Cord

Never carry drill unit by its cord or yank it to discon­nect from receptacle.
Keep cord away from heat, oil, and sharp edges.

16. Do Not Overreach

Keep proper footing and balance at all time.

17. Maintain Tools With Care

Keep tools sharp and clean for better and safer
performance.
Do not use dull or broken Rotabroach Cutters.
Follow instructions for lubricating and changing
accessories.
Inspect tool cords periodically and, if damaged,
have repaired by authorized service facility.
Inspect extension cords periodically and, if
damaged, have repaired by authorized service
facility.
Keep handles dry, clean, and free from oil and
grease.

18. Disconnect Tools

Disconnect when not in use, before servicing, and
when changing Rotabroach Cutters or accessories.

19. Remove Adjusting Keys and Wrenches

Form a habit of checking to see that keys and
wrenches are removed from tool before turning it
on.

20. Check Damaged Parts

Before further use of the drill, a part that is
damaged should be carefully checked to determine
that it willoperate properly and perform its intended
function.
Check for alignment of moving parts, binding of
moving parts, breakage of parts, mounting, and any
other conditions that may affect its operation. A
part that is damaged should be properly repaired or
replaced by an authorized service center unless
otherwise indicated elsewhere in this operator
manual. Do not operate tool if switch does not turn
it on and off.

21.Stay Alert

Watch what you are doing.
Use common sense.
Do not operate tool when you are tired.
Have defective switches replaced by authorized
service center.

22. Outdoor Use Extension Cords

When tool is used outdoors, use only extension
cords intended for use outdoors and so marked.

23. Additional Safety Precautions

Arbor and cutter should never be used as a hand­hold. Keep hands and clothing away from all moving
parts. Do not use Rotabroach Cutters where ejected slug
might cause injury (slug ejected at end of cut).
Also, adhere to all operating instructions. Do not drill
through any surface that may contain live electrical
wiring. Drilling into a live wire could cause exposed metal

parts of the drill to be made live. Remove chips wrapped

around Rotabroach Cutter and arbor after each hole.
With motor off and power disconnected, grasp chips with
leather gloved hand or pliers and pull while rotating
counterclockwise. Should the cutter become jammed in
the work, stop the unit immediately to prevent personal
injury. Disconnect the drill from the power supply and
loosen jammed cutter by turning the arbor counterclock
wise. Never attempt to free the jammed cutter by starting
the motor. Service at authorized repair center only.

24. Non-Conforming Cutting Tools

Your Magnetic Drill is designed to use Hougen
Rotabroach Cutters. The use of drilling tools having
different shank styles is not recommended as they may
not tighten securely in the drill arbor with risk of acci­dent or injury.

25. Operating Near Welding Equipment

When operating your Magnetic Drill near an arc welder,
it is important that they are connected to the same Earth
Ground. If they are not, severe damage to the unit,
particularly the power cord, could occur. This could
also result in personal injury to the operator.

26. Notice
This unit is an Industrial Portable tool and is not designed

for production. If this product is used as a production unit,
internal gear failure could occur and cause serious
damage.

27. Circuit Breaker

Changing of the circuit breaker to a higher amp rated
breaker, or by-passing the circuit breaker is not
recommended and is cause for cancelation of the
product warranty.

28. Circuit Breaker Operation

The circuit breaker is a thermal circuit breaker. When it
reaches the higher temperature rating it will trip and cause
the unit to shut down. This is a protection device and can
be reset after 5 to 10 seconds of cool down period. To
reset the circuit breaker, press the breaker button back in.
If it does not reset, let the unit cool a little longer until you
can push the button in and it stays in position.
