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.

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.

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.
