MAINTENANCE
WARNING:
When servicing, use only identical replacement parts.
Use of any other parts may create a hazard or cause
product damage.
WARNING:
Always wear safety goggles or safety glasses with side
shields during power tool operation or when blowing
dust. If operation is dusty, also wear a dust mask.
GENERAL MAINTENANCE
Avoid using solvents when cleaning plastic parts. Most
plastics are susceptible to damage from various types of
commercial solvents and may be damaged by their use. Use
clean cloths to remove dirt, dust, oil, grease, etc.
ADJUSTMENTS
POSITIVE STOP ADJUSTMENTS
See Figure 44.
NOTE: These adjustments were made at the factory and
normally do not require readjustment.
To adjust:

Unplug the saw.
 Using two wrenches (one on the lock nut and one for
the positive stop adjustment screw), loosen the lock nut
securing the positive stop adjustment screw.
 Loosen the bevel lock knob by turning the knob
counterclockwise.
 Square the blade to the miter table as described in the
Assembly section of this manual.
 Retighten bevel lock knob. Next, retighten lock nut
securing the positive stop adjustment screw. Recheck
blade-to-table alignment.
NOTE: The above procedure can be used to check blade
squareness of the saw blade to the miter table at both 0°
and 45° angles.
The saw has three scale indicators, two on the bevel scale
and one on the miter scale. After squaring adjustments have
been made, it may be necessary to loosen the indicator
screws and reset them to zero.
TO ADJUST THE LASER GUIDE
See Figure 45.
NOTE: Avoid direct eye exposure when using the laser
guide.

Set both the bevel angle and the miter table at 0°.
 Use the work clamp or a C-clamp to secure a piece of
scrap wood.
 Plug the saw into the power source and make a slight
cut to score the wood.
 Release the switch trigger and allow the saw blade to
stop rotating before raising the blade.
 Raise the saw arm and unplug the saw.
 Loosen the blade bolt cover screw on the blade bolt cover
until the cover can be raised.
 Gently raise the lower blade guard bracket so that lower
blade guard and blade bolt cover can be rotated up and
back to expose the laser.
 Rotate the blade by hand until you can push and hold
the laser button and the laser is near the center of the
workpiece as shown in figure 45.
 To adjust the laser, turn the adjustment screw counter-
clockwise or clockwise using the hex key (1/16 in.)
provided.
NOTE: When properly aligned, the laser should be on the
left edge of the kerf.
 Once aligned, remove and store the hex key (1/16 in.).
 Replace the lower blade guard and blade bolt cover.
 Retighten the blade bolt cover screw securely to prevent
guard movement (see page18, figure 18).
NOTE: Always make practice cuts on scrap wood before
cutting through your workpiece.
WARNING:
Do not at any time let brake fluids, gasoline, petroleum-
based products, penetrating oils, etc., come in contact
with plastic parts. Chemicals can damage, weaken or
destroy plastic which may result in serious personal
injury.
Electric tools used on fiberglass material, wallboard, spackling
compounds, or plaster are subject to accelerated wear and
possible premature failure because the fiberglass chips and
grindings are highly abrasive to bearings, brushes, commu-
tators, etc. Consequently, we do not recommend using this
tool for extended work on these types of materials. However,
if you do work with any of these materials, it is extremely
important to clean the tool using compressed air.
