Preparing for Saw Operations

Workpiece Support

Clamps

Using the Workpiece Clamp – This clamp easily

secures a workpiece to the table or base.

1.Insert the clamp’s knurled bar down into a clamp post hole; there are two post holes located in the base behind the fence. The knurled end must be in the post at least 1/2".

2.Slide the clamp down until its rubber foot contacts the workpiece.

3.Adjust the clamp height so it does not touch the sliding fence.

4.Rotate the clamp’s knob until the workpiece is firmly held in place.

5.Move saw head up and down and forward and back to be sure it clears the clamp.

WARNING There may be extreme compound cuts where clamp

cannot be used. Support workpiece with your hand outside the “No Hands” zone. Do not try to cut short pieces that cannot be clamped and cause your hand to be in the “No Hands” zone.
