ASSEMBLY AND ADJUSTMENTS

WARNING: To reduce the risk of injury, turn unit off and
disconnect machine from power source before installing and
removing accessories, before adjusting or changing set-ups
or when making repairs. Be sure the trigger switch is in the OFF
position. An accidental start-up can causeinjury.
Unpacking (Fig. A1, F)
1. Open the box and lift the saw out by the con venient carrying handle
3
,
as shown in FigureF.
2. Place the saw on a smooth, flatsurface.
3. Release the rail lock knob
4
, and push the saw head back to lock it in
the rearposition.
4. Press down lightly on the operating handle
2
and pull out the lock
down pin
9
.
5. Gently release the downward pressure and hold the operating handle,
allowing it to rise to its fullheight.
Bench Mounting (Fig. A1)
Holes
16
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.
Kerf Plate Replacement (Fig. A1)
To remove the kerf plate
21
, remove the screws holding the kerf plate in
place and replace with a new one.
Assemble the screws back in by following this sequence: first through the
round holes located halfway from the ends, then through the slots at the
ends. No adjustment is necessary.
Assembling the Base Extensions (Fig. Y)

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
14
on the side of
thebase.
2. Using a hex wrench, attach the screw
60
through the washer
61
,
through the base extension
13
, and into the holes on thebase.
3. Ensure the extension is secure by pulling on the extension to verify
nomovement.
4. Repeat steps 1 through 3 on the otherside.
NOTE: Make sure the extensions are level with the work surface so that the
workpiece rests evenly. A straight workpiece should have no gap between it
and the base extensions.
