WARNING:
Make sure the spindle lock button is not engaged before
reconnecting saw to power source. Never engage spindle
lock button when blade is rotating.
TO INSTALL / REPLACE THE BLADE
See Figures 17 - 18.
WARNING:
A 1 in. blade is the maximum blade capacity of the saw.
Never use a blade that is too thick to allow outer blade
washer to engage with the flats on the spindle. Larger
blades will come in contact with the blade guards, while
thicker blades will prevent the blade bolt from securing
the blade on the spindle. Either of these situations could
result in a serious accident and can cause serious per-
sonal injury.
 Unplug the saw.
 Raise saw arm.
 Rotate lower blade guard up and remove the blade bolt
cover screw. Rotate blade bolt cover up and back to
expose the blade bolt.
 Depress the spindle lock button and rotate the blade bolt
until the spindle locks.
 Using the wrench provided, loosen and remove the blade
bolt.
NOTE: The blade bolt has left hand threads. Turn blade
bolt clockwise to loosen.
 Remove outer blade washer (or laser guide). Do not
remove inner blade washer.
 Wipe a drop of oil onto inner blade washer (or laser guide)
and outer blade washer where they contact the blade.
WARNING:
If inner blade washer has been removed, replace it before
placing blade on spindle. Failure to do so could cause an
accident since blade will not tighten properly.
 Fit saw blade inside lower blade guard and onto spindle.
The blade teeth point downward at the front of saw as
shown in figure 18.
 Replace outer blade washer (or laser guide). Double "D"
flats on blade washers align with flats on spindle.
 Depress spindle lock button and replace blade bolt.
NOTE: The blade bolt has left hand threads. Turn blade bolt
counterclockwise to tighten.
CAUTION:
Always install the blade with the blade teeth and the
arrow printed on the side of the blade pointing down at
the front of the saw. The direction of blade rotation is also
stamped with an arrow on the upper blade guard.
