NOTE: If the cutter does not release from the arbor
when the collar is turned, use a locking pliers to
grasp the cutter above the cutter flutes. Holding
the collar securely in one hand, rotate the pliers
clockwise to release the cutter from the arbor.
To reduce the risk of injury, do not

hold workpiece by hand.
3. Select High Speed
on your application.
4. Position the tool so the center pin is directly over
the desired cutting location. Rotate the magnet
knob to engage the magnet. The magnet icons will
align . The drill motor will not start if the magnet
is not engaged with the work surface.
To reduce the risk of injury, always

use a safety strap on vertical, over-
head, and pipe applications. Mounting can re-
lease.
5. Use a safety strap on vertical, overhead, and pipe
applications.
A. Route the safety strap, through the lower
slots, and wrap it tightly around a solid, rigid
structure. Make sure the strap is not twisted.
B. Snap the safety strap snaphooks together.
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 the vertical surface.
Do not clamp to the strap. This may damage
the strap and cause it to break.

Do not use cutting fluid in an over-

head or any other position that
allows cutting fluid to enter motor or switch en-
closure.
6. Insert battery pack.
7. With the ON(I) / OFF(O) switch in the OFF(O)
position, turn the cutting fluid bottle valve to the ON
(downward) position. Cutting fluid will be released
as the center pin contacts the work surface.
Failure to lubricate properly will cause cutter
damage. The use of HAWG WASH
is recommended for long life of these cutters.
The operator is responsible for the application of
lubricants other than HAWG WASH
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.
To reduce the risk of in-

jury, always keep hands,
gloves, rags, clothing, etc. away from
moving parts and chips. Do not try to
remove chips while the cutter is rotat-
ing. Chips are sharp and can pull objects into
moving parts.
8. Start the drill motor by pulling the
ON(I) / OFF(O) switch out, by
both sides, to the on(I) position.
The drill motor will not start if the
magnet is not engaged with the
work surface.
Excessive force on the feed handle
WARNING
will break magnet free.
9. Even large bits only require a small amount of
pressure on the feed handle.
When feeding the cutter into the material, apply
only enough force to produce a curled chip. Apply-
ing too little force will result in small broken chips
and increased cutting time. Applying too much
force will cause overheating of the cutter resulting
in short cutter life. Overheating of the cutter can
be noticed when cutter and chips turn brown or
blue. Excessive force can cause the cutter to slow
down to a point where cutting time will increase.
The use of cutting lubricants will reduce cutting
heat and increase cutter life
Use less feed pressure when slotting or notching
because there is less support for the cutting edges
in these situations.
10. Keep constant pressure throughout the entire
operation to prevent chips and burrs from falling
under the cutting edges. Cutting debris under the
cutter can make cutting difficult or impossible.
11. When the cut is complete, withdraw the cutter
while the spindle is still rotating.
12. Stop the drill motor by pushing in the ON(I) / OFF(O)
switch.
13. When the spindle has stopped rotating, use a
pliers to remove cutting debris and chips from the
cutter and spindle. Use care to avoid damaging
the cutter teeth.
