ASSEMBLY

INSTALLING/REMOVING CUTTERS
See Figure 2.
n
Unplug the trimmer.
n Place the trimmer upside down on a workbench to gain
easy access to the spindle and collet nut.
n Place the small end of one of the wrenches provided on
the spindle flats. This will hold the spindle stationary.
n Place the larger end of the other wrench provided onto
the collet nut. Rotate the wrench counterclockwise to
loosen the collet nut as shown in figure 2.
WARNING:
If you are changing a cutter immediately after use, be
careful not to touch the collet 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.
n If installing the cutter for the first time, it can be installed
once the collet nut is loose. If changing cutters, the cutter
will easily slip from the collet after loosening the collet
nut.
NOTE: The tip of the cutter has a protective wax coating
that must be removed before first-time use. Simply peel
off the wax coating and be sure that all traces of wax are
removed before using the trimmer.
n The collet is machined to precision tolerances to fit cut-
ters with 1/4 in. (6.4 mm) diameter shanks.
n With the trimmer still upside down on a workbench, insert
the shank of the cutter into the collet. The shank of the
cutter should be close to but not touching the bottom of
the collet. This allows for expansion when the cutter gets
hot. A clearance of 1/16 in. is adequate.
n Tighten the collet nut securely by turning clockwise with
the wrench provided as shown in figure 2.
WARNING:
If the collet nut is not tightened securely, the cutter may
come out during use, causing serious personal injury.

base screws and laminate sub-base.
n Attach the woodworking sub-base using the same four
screws.
n Tighten the screws securely. Do not overtighten.
