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
See Figures 4 - 5, page 14.
The bit depth can be adjusted by turning the depth
adjustment knob clockwise or counterclockwise. The
depth of the cut can be read on the depth adjustment knob.
Each mark on the scale indicates a 1/128 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.
To use the quick release button:
 Unplug the router.
 Loosen the lock lever.
 Press and hold the quick release button while moving the
router motor up or down in the base.
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, unplug the router, loosen the lock
lever, turn the depth adjustment knob until the bit reaches the
desired depth of cut, and retighten the lock lever.
OPERATION
When the router is mounted to a router table, depth adjust-
ments can be made easily by using a T-handle wrench.
To make through table adjustments:
 Unplug the router.
 Loosen the lock lever.
 Insert a 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.
 When the desired depth of cut is set, tighten the
lock lever.
WARNING:
Do not use with router tables that fail to conform to safe
woodworking practices and offer proper guarding for the
bit. Use router tables that are UL classified and identified
suitable for use with the specific router model. Failure to
comply can result in an accident causing possible injury.
WARNING:
Only use router tables with proper guarding for the bit and
with on-board switch controlled receptacles. Failure to
use router tables with appropriate safety features could
result in serious personal injury.
TURNING THE ROUTER ON AND OFF
See Figure 6, page 14.
To turn the router on, push the switch to the ( I ), or ON
position. Return the switch to the ( O ), or OFF position when
routing operation is finished.
OPERATING THE ROUTER
When routing straight cuts across a workpiece, clamp a
straight edge to the workpiece to use as a guide.
NOTE: Edge guides for the router are also available. See
Accessories.
Position the straight edge parallel to the line of cut and offset
the distance between the cutting edge of the bit and the edge
of the router base. Hold the router base against the straight
edge and rout the groove.
When routing a groove wider than the diameter of the bit,
clamp a straight edge on both sides of the cut lines. Position
both guides parallel to the desired line of cut and spaced
equal distances from the desired edges of the groove. Rout
along one guide then reverse direction and rout along the
other guide. Clean out any remaining waste in the center of
the groove.
