INSTALLING HOUGEN CUTTER IN ARBOR
1. Disconnect from power source.
2. Lay drill on its side with feed handles up or be sure Arbor clears table if unit is in normal operating position.
3. Turn Feed Handles until cutter mounting set screws are exposed and completely remove the set screw.
4. Insert proper pilot in shank end of Hougen Cutter.
5. Insert Hougen Cutter until flat on cutter shank is aligned with set screw holes and is exactly perpendicular to
axis of set screw holes. If 1/2" diameter shank cutter is used, slip (10851) Arbor Adapter over the cutter shank
with adapter hole positioned exactly over flat on cutter shank prior to inserting into Arbor bore.
6. Insert set screws and tighten. When mounting 1/2" diameter shank cutter with adapter, use longer
set screw. (ordered separately) Check to be certain that cutter is secure.

ADJUSTMENT OF GIBS
1. Loosen all Gib Screws (40237).
2. Feed the drill in and out a few times and then, with top of motor slide flush with top of housing, tighten the Gib
Screws until you feel them touch the Steel Gib (02431).
3. Feed the drill in and out again.
4. Adjust Gib Screws so that there is uniform pressure from top to bottom. (Top of motor slide flush with top of
housing.)
5. Turn each Gib Screw in about 1/8 to 1/4 turn, depending upon your preference.
6. Gibs should be tight enough so that slide moves up and down smoothly with no wobble or shaking.
(Looseness will cause cutter breakage.)
NOTE: Gibs should be lubricated regularly.
OPERATION OF CUTTING FLUID RESERVOIR
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, fill reservoir by introducing cutting fluid through slots in Arbor.
Cutting fluid 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 fluid to filter down onto work surface
through groove in pilot.
4. For proper lubrication, all cutting fluid in reservoir should empty onto work surface in no less than 15 seconds
and no longer than 30 seconds.
Adjust Gibs before adjusting front support bracket.
1. Loosen Arbor Support Bracket Bolts.
3. Be sure top of arbor is flush with the shoulder on motor output shaft. Also make certain arbor is securely
fastened.
4. Turn feed handle until motor and spindle are at the bottom of their travel.
5. Tighten Arbor Support Bolts.
6. Feed slide up and down a few times, checking for free and uniform movement.
NOTE: Check Arbor support bolts regularly to make certain they are tight. Tighten as required.
SAFETY SWITCH ADJUSTMENT
1. Unplug unit from power source and place it on a flat sheet of steel that is at least 3/8" thick. Only magnet portion
should be on steel plate. Rear support block (Glide posts should hang over the edge of the steel plate.
2. Remove Access Hole Screw (10977) from the bottom of the panel assembly.
3. Insert 5/32" Allen Wrench into access hole and back off (counterclockwise) Microswitch Adjusting Screw (10969)
about three full turns.
4. Turn adjusting screw in (clockwise) about 1/8 turn at a time (removing wrench, plugging motor to power source,
and turning magnet and motor ON each time) until you find exactly where motor starts.
CAUTION — Turn switches OFF and unplug motor from power source prior to each adjustment.
5. After determining point where motor starts, turn adjustment screw clockwise one and a half turns.
6. Plug unit to power source. Turn Magnet and Motor switches ON. Strike side of magnet at rear with rubber
hammer. Motor should shut off before the magnet moves 1/2" in any direction.
NOTE: Safety Switch adjustment should be checked regularly following the procedure outlined in
Step 6 above.
