1. With Magnetic Drill in operating position, turn feed
handle so that cutter and pilot are above the work
surface.
2. Turn cutting fluid bottle valve to “OFF” position.
3. Remove bottle cap, fill with cutting fluid and replace cap.
4. Open cap vent by turning knurled screw 2 turns.
5. Test metering capabilities (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.
OPERATION OF CUTTING FLUID BOTTLE
Note: As quill is fed toward material, fluid is drawn from
the bottle. As quill is returned to it’s starting
position, fluid will return to the bottle.
Note: Coolant flow has been predetermined. Valve
intended for “ON-OFF” operation only. Trying to
regulate coolant-flow with valve will cause valve to
leak.
See Page 9 for optional Pressurized Coolant Bottle
Assembly.
OPERATING INSTRUCTIONS
1. Make sure workpiece and bottom of magnet are free of
chips, oil, etc.
2. Secure unit to workpiece with safety chain.
3. Position drill by sliding it and gently feeding Arbor so that
pilot point is touching center of hole to be drilled.
4. Turn magnet ON by pressing the MAGNET ON button.
5. Select the proper RPM for the cutter diameter you are
using. Use the 450 setting for 7/16” thru 1-1/16” diameter
and use the 250 setting for 1-1/8” thru 2-3/8” diameters.
Note: The RPM settings for the diameter ranges are to be
used as starting points only. Setting may vary per
application.
6. Turn Feed Handle, raising the cutter until the pilot is
above the work surface.
7. Open the cutting fluid bottle valve.
8. Make certain that cutter is clear of workpiece and turn
motor ON by pressing the MOTOR ON button.
9. Feed Hougen Cutter slowly into workpiece. Only
after cutting path is established to a depth of about 1/16”
can full force be applied to feed handles.
10. Ease up on feed pressure as cutter starts breaking
through.
11. At conclusion of cut, turn motor OFF by pressing motor
STOP button. Turn Feed Handles to raise Arbor thereby
ejecting the slug if it hasn’t already fallen free.
12. Close the cutting fluid bottle valve.
13. Turn magnet OFF by pressing the magnet OFF button.
As the magnet de-energizes, the rear of the magnet
should lift up off the work surface.
14. Disconnect from power source.
15. If necessary, remove chips from cutter and magnet,
preferably wearing leather work gloves and/or with pliers.
16. Disconnect safety chain and you are ready to move unit
to new drilling position.
Special Instructions for Horizontal or Overhead Operation
1.
Always Use Safety Chain.
2. Use Hougen Slick-Stick™ (P/N: 11745-6) or animal-fat
base solid- lubricant applied liberally to cutter.
3. For horizontal use, apply cutting fluid to external parts of
cutter with plastic bottle or oiling can, or use the optional
pressurized coolant bottle assembly (P/N 24140).
MAGNET OPERATION
SPECIAL NOTES:
The magnet on the HMD505 is a dual voltage magnet. When
turning on the magnet a control voltage is supplied to the
magnet. When you turn the motor on, the control voltage is
increased to the magnet. This combination provides a better
holding power on the work surface.
With this special feature however, it requires that you do not
leave the magnet and motor on for extended periods of time.
This does not impede the normal performance of your unit. The
increased holding power if left on could cause overheating of
the unit. Take care of your unit by unplugging your unit when not
in use. Failure to follow these special guide lines could cause
damage to your unit and therefore result in personal injury.
Always remember that the magnet’s holding power is directly
related to the workpiece thickness and surface condition. Since
magnetic attraction diminishes with thinner material or rough
surfaces, mechanical clamping of drill unit to the workpiece
should be used when cutting thin material (3/8” or less) or
material with uneven surfaces.
