To reduce the risk of injury, wear safety goggles or glasses with
side shields.
Typical Operation
1. Check the work surface to make sure it is clean and free of foreign
materials.
Paint, rust, scale or uneven surfaces decrease the holding strength of
the magnet. Chips, burrs, dirt and other foreign materials on the surface
of the magnetic base will also decrease holding power. Use a smooth,
fl at fi le to keep the magnet clean and free of nicks.
The electromagnetic drill press attaches magnetically to 3/8" or thicker
ferrous stock. Do not use on stock less than 3/8". The magnetic base
WILL NOT hold on nonmagnetic grades of stainless steel.
2. To install/remove cutter:
A. Raise the drill motor to its highest position. Tighten stop knob.
B. Insert cutter into drill spindle with the two (2) fl ats of the cutter
aligned with set screws. Make sure the center pin is inserted
into the cutter.
NOTE: Cutter should be fully seated into drill spindle.
C. Tighten set screws with 3/16" hex key provided.
D. Loosen the stop knob.
E. Reverse procedure to remove cutter.
NOTE: Do not remove cutter unless slug is removed. Slug may
eject unexpectedly.
Avoid contact with cutter tips. Periodically inspect the cutter tips for
loose or damaged tips.
3. Plug in tool to power source.
• Do not use cutting fl uid in an overhead or any other position
that allows cutting fl uid to enter motor or switch enclosure.
• Wet connections are shock hazards. Prevent cutting
fluid from traveling along cord and contacting the out-
let, extension cord connections or tool plug. Each time
tool is plugged in, elevate extension cord or gang box
connections and arrange a drip loop (See Fig. 6). If plug
or connections get wet, turn power off to outlet before
unplugging tool.

4. Move the spindle up so the cutter and center pin are above the work
surface.

OPERATION
To reduce the risk of injury, do not hold workpiece by hand.
5. Position the tool so the center pin is directly over the desired cutting
location. Push the magnet switch to the "ON" position. The magnet
indicator light will turn on.
To reduce the risk of injury, always use a safety strap when drilling
overhead or on a vertical surface.
6. Use a safety strap on vertical or overhead situations (Fig. 7).
A. Route the safety strap, ring side fi rst, through the lower slot,
and wrap it tightly around a solid, rigid structure as shown.
Make sure the strap is not twisted.
B. Hook the safety strap snaphook provided to the ring.
Eliminate any slack in the strap.
C. When using on a vertical surface, secure the safety strap
with a c-clamp or similar device. This will hold the strap in
place and prevent the tool from sliding
surface.
NOTE: Do not clamp to the strap. This may damage the strap
and cause it to break (Fig. 7).

7. With the drill on/off switch in the "OFF" position, fill the cutting
fl uid reservoir with cutting fl uid through the slots in the drill spindle
(Fig. 8).
Fig. 8
The cutting fl uid reservoir will empty as the center pin contacts the
work surface. When notching or slotting, it is required to spray cutting
fl uid directly to the cutter and work piece with the supplied hand pump.
Keep hand pump away from moving parts. Failure to use the lubricant
properly will cause cutter damage.
The use of HAWG WASH® cutting fl uid is recommended for long
life of these cutters. The operator is responsible for the application of
lubricants other than HAWG WASH® cutting fl uid.
In overhead or vertical cutting applications, do not use cutting
fl uids. Use only lubricant pastes or sprays recommended for high speed
cutting. Do not allow lubricant pastes and sprays to enter tool.
