COLLET NUT
CUTTER WITH 1/4 in.
SHANK DIAMETER
WARNING:
If the collet is not securely tightened,
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 serious
personal injury.
WARNING:
Do not use cutters that are larger in
diameter than the opening in router base. Use of
such cutters will come in contact with the router
base and damage both the cutter and the router
base. This situation could also cause possible loss
of control or create other hazardous conditions that
could cause possible serious personal injury.
SELECTING DEPTH OF CUT
Proper depth of cut depends on several factors: the
horsepower of the router motor, the type of cutter, 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 cutters,
such as veining cutters with 1/16 in. cutting diameters,
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.

OPERATION
TO ADJUST DEPTH OF CUT
See Figures 6 - 8.
 Unplug the router.
 Raise cutter by unlocking plunge lock lever.
 Adjust hex nuts on threaded post until cutter is inside
router subbase.
 Place router on a flat surface.
 Lower router until tip of cutter barely touches flat
surface.
 Lock plunge lock lever to position cutter at zero depth
of cut.
 Adjust hex nuts until they come in contact with stop
flange. This will provide a position stop at zero depth of
cut.

 Make sure the hex nuts are securely tightened against
each other.
