WARNING:
Always wear safety goggles or
safety glasses with side shields when using your
trimmer. Failure to do so could result in dust,
shavings, chips, loose particles, or foreign
objects being thrown into your eyes resulting in
possible serious injury. If the operation is dusty,
also wear a face or dust mask.
_
WARNING:
When turning your trimmer ON, be
prepared for start-up torque. Always have a firm
grasp of your trimmer before starting. Because of
the high cutter speed rotation your trimmer has a
tendency to twist, jerk, or grab in your hands
during start-up. If not prepared, this can cause a
loss of control resulting in possible serious injury.
HOW TO OPERATE
YOUR TRIMMER
Before starting your trimmer, unplug it and make sure
cutter is securely tightened in collet and that depth of
cut is properly set. Never start trimmer
while cutter
is in contact with the workpiece.
After completing a cut, pull cutter slightly away from
cut surface. Turn trimmer
off and wait for rotating
cutter to completely stop before removing base from
work surface.
Your trimmer is turned on by means of a slide switch
located on top of the tool. Make a few cuts on a piece
of scrap material to determine the desired depth or
shape of cut. When cutting, fit the base of your
trimmer over the work surface and firmly hold the
body of your trimmer with your hand. Make sure the
trimmer is running at full speed. For best results,
move your trimmer from left to right, against the
turning direction of the trimmer cutter. See Figure 4.
Be sure not to move trimmer too rapidly.

Remain alert and watch what you are doing. Do not
operate trimmer when fatigued or under the influence
of drugs, alcohol, or any medication.
FEED DIRECTION
When trimming, the cutter rotates clockwise.
Therefore, you should feed the trimmer into the
workpiece from left to right. When fed from left to
right, the rotation of the cutter pulls the trimmer
against the workpiece. If fed in the opposite direction,
the rotation forces of the spinning cutter will tend to
throw the trimmer away from the workpiece. This
could cause loss of control of your trimmer.
RATE OF FEED
IMPORTANT:
The whole "secret" of professional
trimming and edge shaping lies in making a careful
set-up for the cut to be made and in selecting the
proper rate of feed.
The proper rate of feed depends on several factors:
the hardness and moisture content of the workpiece,
the depth of cut, and the cutting diameter of the cutter.
When cutting shallow grooves in soft woods such as
pine, a faster rate of feed can be used. When making
cuts in hardwoods such as oak, a slower rate of feed
will be required.
The best rate of feed is one that does not slow down
the trimmer motor more than one-third of its no-load
speed. If the trimmer is fed too fast, it will take large
chips out of the wood and leave gouge marks. If the
trimmer is fed too stow, it will scorch or burn the wood.
PROPER
FEEDING
The right feed is neither too fast nor too slow. It is the
rate at which the cutter is being advanced firmly and
surely to produce a continuous spiral of uniform chips
or a smooth trim edge on laminate. If you are making
a small diameter, shallow groove in soft, dry wood,
the proper feed may be about as fast as you can
travel your trimmer
along your guide line. On the
other hand, if the cutter is a large one, the cut is deep
or the workpiece is hard to cut, the proper feed may
be a very slow one. A cross-grain cut may require a
slower pace than an identical with grain cut in the
same workpiece.
There is no fixed rule. You will learn by experience
from practice and use. The best rate of feed is deter-
mined by listening to the sound of the trimmer motor
and by feeling the progress of each cut. Always test a
cut on a scrap piece of the workpiece wood or lami-
nate beforehand.
BALL BEARING
PILOTED
BIT
See Figure 4.
Use of ball bearing piloted trimmer cutters provide a
convenient method of laminate trimming. Guide the
ball bearing surface along the edge of workpiece.
Be
careful to follow instructions for correct direction of
feed.
