To start the tool, depress the trigger switch (A). To turn the tool off,
release the trigger switch. Keep hands and material from blade until
it has coasted to a stop.
CAUTION: MAKE SURE THE BLADE IS NOT TOUCHING THE
WORKPIECE WHEN THE TOOL IS STARTED.
Cut t ing Proc e ss Che c k list
1. BEFORE STARTING THE TOOL, MAKE SURE:
• Tool is securely mounted on a stable surface.
• Blade is mounted correctly and blade bolt is tight.
• Fence is set properly and locked in place.
• Workpiece is held firmly in the vise and vertically clamped as
described.
• Chip deflector is properly adjusted.
2. Start the motor and allow the blade to come up to full speed.
3. Pull the handle down slowly to make initial contact with the

workpiece. Once contact is made, increase feed rate, allowing
the blade to do the work. Slow down just before the cut is
complete.
4. After the cut is complete, turn the tool off and keep hands away
until blade has stopped spinning.
CAUTION: When cutting small pieces, (less than one inch) the
scrap may be thrown toward the rear of the unit.
Good Ca re /Cut t ing Pra c t ic e s
1. The blade teeth are made of carbide material which is very hard,
yet brittle. Vibration increases side loads that could cause chipping
of teeth or cracking of the blade. Here are some important tips that
will help prolong the life of the blade and the tool:
• Position the workpiece as much as possible under the down-
stroke of the blade (Figure 10). Material must be firmly clamped
and supported to reduce vibration. NO EXCEPTIONS.
• Never perform cuts on small workpieces bundled together.
• Position the workpiece so that the blade is cutting through the
smallest cross section.
• Avoid cutting large, flat, horizontal surfaces where possible. The
lowest number of blade teeth contacting the workpiece during the
cut will produce the least amount of heat and increase blade life.
2. The following signs indicate that the blade is worn and should be
resharpened or replaced:
• Poor cutting performance.
• More sparks than chips created during a cut.
• The ringing sound of the blade increases.

location)
1. Drill four holes 5/16" through the work surface. (Figure 14)
