26. Circuit Breaker
Changing of the circuit breaker to a higher amp rated breaker, or
bypassing the circuit breaker is not recommended and will void
product warranty.
27. Circuit Breaker Operation
The circuit breaker is a thermal breaker. When it reaches the
higher temperature rating it will trip and cause the unit to shut
down. This is a protective device and can be reset after 5 to 10.
To reset the 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.
28. Safe Electrical Connection
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. Also elevate
extension cords or gang box
connections.

Important Safety Instructions - Continued
18. Maintain Tools With Care
Keep tools sharp and clean for better and safer
performance. Do not use dull or broken Hougen 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.
19. Disconnect Tools
Disconnect when not in use, before servicing, and
when changing cutters or accessories.
20. Remove Adjusting Keys and Wrenches
Form a habit of checking to see that keys and
wrenches are removed from tool before turning it
on.
21. Check Damaged Parts
Before further use of the drill, a part that is
damaged should be carefully checked to determine
that it will operate 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.
22. Stay Alert
Watch what you are doing and use common sense.
Do not operate tool when you are tired.
Have defective switches replaced by authorized
service center.
23. Outdoor Use Extension Cords
When tool is used outdoors, use only extension
cords intended for use outdoors and so marked.
24. Additional Safety Precautions
Arbor and cutter should never be used as a hand-
hold. Keep hands and clothing away from all moving
parts. Do not use Hougen 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 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.
25. Operating Near Welding Equipment
DO NOT operate this unit on the same work surface that
welding is being performed on. Severe damage to the
unit, particularly the power cord, could occur. This could
also result in personal injury to the operator.
