SAFETY SWITCH
INDICATOR LIGHT
The Safety Switch Indicator Light is a Standard Safety
feature on Trak-Star 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 fl atness.
• 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.

MD50 & MD70
MD40
OPERATING INSTRUCTIONS
Always remember that the magnet’s holding power is directly related to the work piece thickness and surface
condition. Since magnetic attraction diminishes with thinner material or rough surfaces, mechanical clamping
of drill unit to the work piece should be used when cutting thin material (3/8” or less) or material with uneven
surfaces.
1. Make sure work piece and bottom of magnet are free of chips, oil, etc.
2. Position drill by sliding it and gently feeding Arbor so that pilot point is touching center of hole to be drilled.
3. Secure unit to work piece with safety chain or strap.
4. Turn magnet ON by pressing the magnet ON switch.
5. Turn Feed Handle, raising the cutter until the pilot is above the work surface.
6. Make certain that cutter is clear of work piece and turn motor ON by pressing the motor START switch.
7. Feed the Trak-Star Cutter slowly into work piece. Only after cutting path is established to a depth of about 1/16”
can full force be applied to feed handles.
8.
Ease up on feed pressure
Ease up on feed pressure
as cutter starts breaking through.
9. At conclusion of cut, turn motor OFF by pressing motor STOP switch. Turn Feed Handles to raise Arbor
thereby ejecting the slug if it hasn’t already fallen free.
10. Turn magnet OFF by pressing the magnet OFF switch.
11.
Disconnect from power source.
12. If necessary, remove chips from cutter and magnet, preferably wearing leather work gloves and/or with pliers.
Disconnect safety chain and you are ready to move unit to new drilling position.

USING THE SAFETY STRAP OR SAFETY CHAIN
USING THE SAFETY STRAP OR SAFETY CHAIN
MD40
The Safety Strap should be used to prevent the drill unit from falling in the event of a power failure or if the magnet breaks
loose from the work surface. On the MD40, the Safety Strap should be attached to the drill by running it between the Motor
and Drill Housing and then continue around the material and/or work surface, Dia.1. Ensure that the Strap does not interfere
with the operation of the feed handle. Insert the end of the strap into the buckle, Dia.2, and pull the strap tight to the material
MD50 & MD70
The Safety Chain should be used to prevent the drill unit from falling in the event of a power failure or if the magnet breaks
loose from the work surface. On the MD50 and MD70, the Safety Chain should be attached to the drill by running it between
the Front Support Bracket and the Drill Housing and then continue around the material and/or work surface. Refer to dia 3.

USING CUTTER LUBRICANT AND CUTTING FLUID
MD40
When using the Trak-Star Low Profi le Mag Drill with the RotaLoc Plus Cutters, it is recommended to use the Slick-Stik Lubri-
cant. This is a paste style lubricant that is applied directly to the cutter fl utes and teeth. During the cutting operation, the Slick-
Stik will melt and offer lubrication through the cut.
8
Using Cutter Lubricant and Cutting Fluid cont.
MD50
When using a Trak-Star Mag. Base Drill without a Coolant Bottle, the Rotamagic can still be added directly through the Arbor
Body. The Rotamagic cutting fl uid is sold as a concentrate and must be diluted with water at a 10:1 ratio.
1. With Magnetic Drill in operating position, turn the feed handles so that cutter and pilot are above the work surface.
2. With magnet turned ON and motor OFF, fi ll the inside of the Arbor Body by introducing cutting fl uid through slots in Arbor.
Cutting fl uid should not leak out.
3. Test metering capabilities of Arbor/Cutter/Pilot assembly (magnet ON-motor OFF) by feeding the Arbor gently
toward work surface until pilot is pushed up into Cutter, thus allowing fl uid to fi lter down onto work surface
through groove in pilot.
4. For proper lubrication, all cutting fl uid in Arbor Body should empty onto work surface in no less than 15 seconds
and no longer than 30 seconds.
MD70
The Trak-Star Mag. Base Drills with the Coolant Bottle, will deliver the Rotamagic Cutting Fluid through the Arbor Body directly
to the cutting teeth. The Rotamagic cutting fl uid is offered as a concentrate, and will need to be diluted with water at a 10:1
ratio.
1. With Magnetic Drill in operating position, turn the feed handles so that cutter and pilot are above the work surface.
2. With magnet turned ON and motor OFF, verify that the Coolant Bottle Valve is closed and fi ll the inside of the Coolant
Bottle with the diluted Rotamagic cutting fl uid.
Cutting fl uid should not leak out.
3. With the cutter and pilot pin still up and not touching the work surface, open the valve at the base of the Coolant Bottle 1/4
turn.
4. Test metering capabilities of Arbor/Cutter/Pilot assembly (magnet ON-motor OFF) by feeding the Arbor gently
toward work surface until pilot is pushed up into Cutter, thus allowing fl uid to fi lter down onto work surface
through groove in pilot.
5. Once you have verify that the Rotamagic cutting fl uid is reaching the work surface, bring the cutter and pilot pin up off of
the work surface and continue to the Operation Instructions.

1. Keep insides of Hougen Cutter clear of chips. Chips will interfer with cutting to maximum depth, may
impede the free oil fl ow and can cause cutter breakage.
2. Keep work, machine, arbor and Hougen Cutter free of chips and dirt.
3. Tighten all bolts and fasteners regularly.
4. We highly recommend using a light viscosity cutting fl uid (preferably
Hougen Cutting Fluid - Part No. 11742-4)
5. Occasionally check metering of cutting fl uid fl ow. Lack of cutting fl uid
may cause Hougen Cutter to freeze in cut, slug to stick and may
result in poor cutter life.
6. Always start cut with light feed pressure and then increase suffi ciently to
achieve maximum cutting rate.
7. Ease off on pressure as cutter begins to break through at the end of the cut.
8. Keep slide dovetails, brass gibs and feed rack lubricated and free of chips and dirt.
9. When slug hangs up in cutter, turn off motor and bring cutter down on a fl at surface. This will normally
straighten a cocked slug, allowing it to be ejected.
10. When cutting large diameter or deep holes it may be necessary to stop in the middle of the cut to add
cutting fl uid and remove the chips from around the arbor. (When doing this DO NOT raise the cutter out of
the hole. Doing so can allow chips to get under the teeth of the cutter and make it diffi cult to restart the
cut.)
* ”Babying” the cutter through the cut will only decrease tool life.
HINTS FOR SMOOTHER OPERATION
#1 cause of cutter
breakage and
prematurely dull
teeth is too little
feed pressure*
MAINTENANCE
In order to minimize wear on moving parts and to insure smoother operation and longer life for your magnetic
drill, the following maintenance should be done periodically, based on use.
1. Regularly tighten all fasteners and replace all worn parts.
2. Check motor brushes and replace if worn. (Break in period - 30 minutes at no load speed)
3. Check power cord and cord from panel to motor and, if cracked or frayed, return to an authorized repair
center for replacement.
4. Apply grease to the slide dovetails, brass gibs, and the feed gear rack. For best results use Shell Cyprina-
RA or equivalent.
5. Remove arbor and pack the bearing in the front support bracket with grease. Use Shell Cyprina-RA or
equivalent.
