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, flat file 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) flats 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 fluid in an overhead or
any other position that allows cutting fluid
to enter motor or switch enclosure.
• Wet connections
Prevent cutting fluid from traveling along
cord and contacting the outlet, 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.

are shock hazards.
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 first, 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 down
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 fluid
reservoir with cutting fluid through the slots in the drill spindle
(Fig. 8).
Fig. 8
The cutting fluid reservoir will empty as the center pin contacts the
work surface. When notching or slotting, it is required to spray
cutting fluid 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 fluid is recommended for long life
of these cutters. The operator is responsible for the application of
lubricants other than HAWG WASH® cutting fluid.
In overhead or vertical cutting applications, do not use cutting
fluids. Use only lubricant pastes or sprays recommended for high speed
cutting. Do not allow lubricant pastes and sprays to enter tool.
