Unpacking (Fig. A, G)
1. Open the box and lift the saw out by the con venient carrying handle
Figure G.
2. Place the saw on a smooth, flat surface.
3. Release the rail lock knob 23 , and push the saw head back to lock it in the rear position.
4. Press down lightly on the operating handle
5. Gently release the downward pressure and hold the operating handle, allowing it to rise to
its full height.
Bench Mounting (Fig. A, GG)
Holes 6 are provided in all four feet to facilitate bench mounting. Two different-sized holes are
provided to accommodate different sizes of screws or bolts. 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 or bolts 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.
Assembling the Base Extensions (Fig. II)

WARNING: Base extensions must be assembled to both sides of the saw's base
before using the saw.

WARNING: Be sure to adjust the base extensions using the mounting slots so they
are level with the saw's base.
1. Locate the holes above the hand indentations on the side of the base.

Installing and Removing the Battery Packs from the Tool (Fig. C1)
nOTE: For best results, make sure your battery packs are fully charged.
To install the battery packs 21 into the tool, align the battery packs with the rails on the side
of the motor housing and slide them in until they are firmly seated in the tool and ensure that

green LED lights will illuminate designating the level of charge left. When the level of charge
in the battery is below the usable limit, the fuel gauge will not illuminate and the battery will
need to be recharged.
nOTE: The fuel gauge is only an indication of the charge left on the battery pack. It does
not indicate tool functionality and is subject to variation based on product components,
temperature and end-user application.
