1. With Magnetic Drill in operating position, turn feed
handle so that cutter and pilot are above the work
surface.
2. Turn cutting fl uid bottle valve to “OFF” position.
3. Remove bottle cap, fi ll with cutting fl uid 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 fl uid to fi lter down
onto work surface through groove in pilot.
OPERATION OF CUTTING FLUID BOTTLE
Note: As quill is fed toward material, fl uid is drawn from
the bottle. As quill is returned to it’s starting position, fl uid
will return to the bottle.
Note: Coolant fl ow has been predetermined. Valve
intended for “ON-OFF” operation only. Trying to
regulate coolant-fl ow 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 12mm (7/16”) thru 26mm
(1-1/16”) diameter and use the 250 setting for 27mm (1-1/8”)
thru 52mm (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 fl uid 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 fl uid 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 fl uid to external parts of
cutter with plastic bottle or oiling can, or use the optional
pressurized coolant bottle assembly (P/N 24140).
MAGNET OPERATION
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 (10mm - 3/8” or less)
or material with uneven surfaces.
