Additional Workpiece Support
Always ensure that support-
ing surfaces are able to
properly support the workpiece and allow for
secure holding by hand outside of the "No
Hand Zone", or clamping with a clamp inside or
outside of the "No Hand Zone." (See "Body
and Hand Position" on page 29 for the "No
Hand Zone" and the appropriate hand posi-
tions.)
Be aware of the path of the
saw blade. Make a dry run
with the battery pack disconnected and the
saw switched OFF by conducting a simulated
cutting cycle, and observe the projected path
of the saw blade. Keep hands at least six (6)
inches (152mm) away from the projected path
of the saw blade.
Blocks – Long pieces need extra support. The
base height (3-1/2" / 89mm) is designed to
match the standard lumber of one 4x or two 2x.
Boards of these thicknesses can be used to cre-
ate auxiliary support extensions for long work-
pieces (Fig. 37).

Making an Auxiliary Fence
Check for interference be-
tween auxiliary fence and
saw head components by performing a dry
run. Fence interference can prevent proper saw
operation and cause injury and/or tool damage.
Be aware of the path of the
saw blade. Make a dry run
with the saw OFF by conducting a simulated
cutting cycle, and observe the projected path
of the saw blade. Keep hands at least six (6)
inches (152mm) away from the projected path
of the saw blade.
Certain types of molding need a fence face ex-
tension because of the size and position of the
workpiece. Holes are provided in the fence to
attach an auxiliary fence. Only use the auxiliary
fence with the saw in the 0° bevel position.
1. To create an auxiliary fence (Fig. 38), place a
piece of wood against the sliding fence (Fig.
36, 12). Wood can have a maximum height of
5-1/2" (140mm). Check that auxiliary fence
assembly (Fig. 38) does not interfere with
the saw head assembly (Fig. 37, 28).

the wood from the back side of the fence.
3. Drill and countersink the holes on the front
of the support board.
