Basic Saw Operations

Workpiece Support

!WARNING Long workpieces have a tendency to tip over unless clamped down and properly

supported from underneath.

Clamps

Quick Action Clamp - This clamp easily secures a workpiece in any of six (6) clamp holes around the saw (Figure 21).

Insert clamp post into clamp hole 1.

Adjust screw rod 2 to proper height, if necessary.

Press down on lever 3 to tighten clamp.

Move the head assembly to check clearance with clamp.

Pull up on lever to release clamp.

!WARNING There may be extreme compound cuts where clamp cannot be used. Support

with hand outside 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.

Conventional Clamps and other hold down devices can be used to hold the workpiece firmly against the table and the fence.

Long Workpiece Support

Blocks - Long pieces need extra support. The base height (3-3/4”) is designed to match the standard lumber of two 2x4’s and one 1x4. Boards of these thicknesses can be used to create auxiliary support extensions for long workpieces (Figure 22).

Extension and Stock Stop - This attachment (accessory BB1204) allows extra support for the longer workpieces. Refer to the accessory instruction sheet for details (Figure 23). See page 74 for a complete accessory list.
