Basic Saw Operations
Workpiece Support
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.
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
2x4s 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.
