Bench Mounting (Fig. A1)
16
Holes
are provided in all four feet to facilitate bench mounting. Two
different-sized holes are provided to accommodate different sizes of screws.
Use either hole; it is not necessary to use both.
Always mount your saw firmly to a stable surface to prevent movement.
To enhance the tool's portability, it can be mounted to a piece of 12.7 mm
or thicker plywood which can then be clamped to your work support or
moved to other job sites and reclamped.
nOTE: If you elect to mount your saw to a piece of plywood, make sure that
the mounting screws don't protrude from the bottom of the wood. The
plywood must sit flush on the work support. When clamping the saw to
any work surface, clamp only on the clamping bosses where the mounting
screw holes are located. Clamping at any other point will interfere with the
proper operation of the saw.
CAUTION: To prevent binding and inaccuracy, be sure the mounting
surface is not warped or otherwise uneven. If the saw rocks on the
surface, place a thin piece of material under one saw foot until the saw
sits firmly on the mounting surface.
