WARNING: If the collet nut is not securely tight-
ened, the cutter may detach during use, causing
serious personal injury.
WARNING: Do not use cutters with undersized
shanks. Undersized shanks will not tighten properly
and could be thrown from the tool causing injury.
WARNING: Do not use cutters that are larger in di-
ameter than the opening in router base. Use of such
cutters will come in contact with the router base
and damage both the cutter and router base. This
situation could also cause possible loss of control or
create other hazardous conditions that could cause
possible serious personal injury.

WARNING: If you are changing a cutter immedi-
ately after use, be careful not to touch the cutter nut,
cutter, or collet with your hands or fingers. They will
get burned because of the heat buildup from cutting.
Always use the wrench provided.
INSERTING / REMOVING CUTTERS / BITS
See Figure 7.
[] Unplug the router.
To insert the cutter/bit:
[] Depress and hold the spindle lock button.
[] Insert the shank of the cutter until the shank bottoms
out, then pull it out 1/16 in. to allow for expansion
when the cutter gets hot.
[] Tighten the collet nut securely by turning it clockwise
with the wrench provided.
[] Release the spindle lock button.
To remove the cutter/bit:
[] Lay the router down on a workbench to gain access to
the collet nut.
[] Loosen the locking knob on the plunge base or the
locking arm on the fixed base.
[] Depress and hold the spindle lock button.
[] Loosen the collet nut by turning it counterclockwise
with the wrench provided.

SELECTING DEPTH OF CUT
Proper depth of cut depends on several factors: the
horsepower of the router motor, the type of cutter / bit,
and the type of wood. A lightweight, low horsepower
router is designed for making shallow cuts; a router with
higher horsepower is designed for deeper cuts. Small cut-
ters, such as veining cutters with 1/16 in. cutting diame-
ters, are designed to remove only small amounts of wood.
Large cutters, such as straight-flute cutters, remove larger
amounts of wood and make deeper cuts in soft woods,
such as white pine.
Choose a depth of cut that will not place excessive strain
on the router motor. If you need extra force or the motor
speed slows down considerably, turn off the router and
reduce the depth of cut. Then, make the cut in two or
more passes.
When routing a groove that is too deep to safely cut in
one pass, make the cut in several passes. We recommend
that cuts be made at a depth not exceeding 1/8 in. and
that several passes be made to reach deeper cuts.
Adjusting the depth of cut for the plunge router is different
from adjusting the depth of cut for the fixed router.
