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 sedous 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 workpieee.
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 itsno-load speed. Ifthe
trimmer is fed too fast, it will take large chips out of the wood
and leave gouge marks. If the trimmer is fed too slow, 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 orthe 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 determined 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 laminate beforehand.
BALL BEARING
PILOTED
BIT
See Figure 4.
Use of ball bearing piloted trimmer cutters provide a conve-
nient method of laminate trimming. Guide the ball bearing
surface along the edge of workpiece.
Be careful to follow
instructions for correct direction of feed.
