To remove the bit:

Using the supplied wrench, hold the collet nut with one
wrench or depress and hold the spindle lock until it locks
into place.
 Loosen the collet nut and remove the bit.
 Release the spindle lock if necessary.
SELECTING DEPTH OF CUT
Proper depth of cut depends on several factors: the horse-
power of the router motor, the type of 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 bits, such as veining bits
with 1/16 in. cutting diameters, are designed to remove only
small amounts of wood. Large bits, such as straight-flute
bits, 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.
SETTING DEPTH OF CUT FOR FIXED BASE
ROUTING
See Figures 6 - 7.
The bit depth can be adjusted by turning the depth adjust-
ment knob clockwise or counterclockwise. The depth of the
cut can be read on the depth adjustment knob. Each mark
on the scale indicates a 1/64 in. change in depth setting.

Unplug the router.
 Loosen the lock lever.
 Turn the depth adjustment knob counterclockwise to
move the collet down or clockwise to move the collet
up.
NOTE: It should not be possible to make depth adjust-
ments with the lock lever tightened. If depth adjustments
are possible with the lock lever tightened, an adjustment
to the lock lever needs to be made. See Adjustments.
 When the desired depth of cut is set, tighten the lock
lever.
NOTE: To adjust the depth of cut when the router is mounted
to a router table, loosen the lock lever, turn the depth adjust-
ment knob until the bit reaches the desired depth of cut, and
retighten the lock lever.
When the router is mounted to a router table, depth adjust-
ments can be made easily by using the supplied T-handle
wrench.
To make through table adjustments:

Unplug the router.
 Loosen the lock lever.

 Insert the T-handle wrench through the hole in the router
table into the hole on the subbase, and place the end of
the wrench socket over the adjusting nut.
 Turn the wrench counterclockwise to move the collet
down or clockwise to move the collet up.
NOTE: It should not be possible to make depth adjust-
ments with the lock lever tightened. If depth adjustments
are possible with the lock lever tightened, an adjustment
to the lock lever needs to be made. See Adjustments.
