Hold-downs
The purpose of the pneumatic hold-downs is to
secure the stock in the desired position up against
the fence and to prevent the workpiece from being
drawn into the center of the saw by the rotational
force of the blades.
The pneumatic hold-downs must be cor-
rectly adjusted to firmly hold the workpiece
against the fence before the cutting opera-
tion begins. If the workpiece is drawn into
the saw by the rotation force of the blades,
personal injury or damage to the machine
may occur.
To correctly adjust the hold-downs:
1. DISCONNECT SAW FROM POWER!
2. DISCONNECT SAW FROM AIR SUPPLY!
3. Remove the two thumb screws from the front
guard and raise it to the upper position.
5. Use a 13mm wrench to loosen the upper and
lower hold-down jam nuts.
6. Position the hold-downs horizontally along
the mounting bars over the flatest part of the
workpiece so that they grip and secure the
workpiece against the fence.
7. Re-tighten the jam nuts to keep the hold-
downs in place.
8. Lower the front guard and secure it in place
with the thumb screws.
9. Adjust the side transparent guards just slight-
ly above the workpiece for maximum protec-
tion.
10. Re-connect the machine to the air supply,
then press the foot pedal actuator to test the
positioning of the hold-downs. Repeat the
steps above if necessary.

NOTICE
When the front guard is in the upper posi-
tion, the machine cannot be turned ON.
When the front guard is secured in the down
position, the safety switch is activated and
power can flow to the motor.
4. Position your workpiece under the hold-downs,
then lower the hold-downs by hand until they
touch the workpiece (see
Figure 16).
