Familiarization
Place the saw on a smooth, flat surface such as a work-
bench or strong table. Examine Figures 1 & 2 and refer
to the parts description to become familiar with the saw
and its various parts. The following section on adjust-
ments will refer to these terms and you must know what
and where the parts are. The part name is followed by
the corresponding part number Example - lock down pin
(10). Press down lightly on the operating handle and pull
out the lock down pin (10), as shown in Figure 3. Gently
release the downward pressure and allow the arm to rise
to its full height. Use the lock down pin when carrying the
saw from one place to another. Use the operating
handle (1) to transport the saw or the hand indentations
(11) shown in Figure 2 after unplugging.

Bench Mounting
Bench mounting holes (8) are provided in all four feet to
facilitate bench mounting, as shown in Figure 1. (Two dif-
ferent 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 prevent movement.
To enhance the tool's portability, it can be mounted to a
piece of 1/2" 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.
