Safe Electrical Connection
Your Mag Drill is rated for use on 115VAC or
230V at 50-60Hz. Do not attempt to use drill on
power sources rated other than this.
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.
Outdoor Use Extension Cords
When tool is used outdoors, use only extension
cords intended for use outdoors and so marked.
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.

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.
Circuit Breaker (If Applicable)
Changing of the circuit breaker to a higher amp rated breaker, or
bypassing the circuit breaker is not recommended and will void
product warranty.
Circuit Breaker Operation (If Applicable)
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.
Save these Instructions.

SAFETY SWITCH
INDICATOR LIGHT
The Safety Switch Indicator Light is a Standard Safety
Feature on HMD904 magnetic drills. Its purpose is to inform
the user that an unsafe condition exists.
If light is Green:
In normal operation the safety switch light will be green.
Motor “On” and “Off” Switches function normally.
If light is Red:
A condition with the safety switch exists that needs to be
corrected.
Possible causes:
• Safety Switch is defective. Have drill serviced.
• Uneven work surface or material. Check work
surface for flatness.
• Dirt or chips under magnet. Clean work surface.
Material should be a least 3/8” thick. Material thinner
than 3/8” will cause a “weak” magnet condition.
HOUGEN MANUFACTURING RECOMMENDS THAT
CONDITIONS ARE CORRECTED SO LIGHT TURNS
GREEN. THIS ALLOWS FOR THE UNIT TO BE
OPERATED IN A SAFE MANNER.
For any questions please contact Hougen Manufacturing’s
Technical Service at (810) 635-7111.
