ASSEMBLY
TO INSTALL / REPLACE THE BLADE
See Figure 13.
WARNING:
A 12 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 personal injury.
 Unplug the saw.
 Raise saw arm.
 Using the Phillips screwdriver end of the blade wrench,
loosen, but do not remove, the blade bolt cover screw.
Slide blade bolt cover toward upper blade guard to
expose the blade bolt.
 Depress the spindle lock button and rotate the blade bolt
until the spindle locks.
 Using the hex end of the blade wrench, loosen and
remove the blade bolt.
NOTE: The blade bolt has left hand threads. Turn blade
bolt clockwise to loosen.
 Remove the outer blade washer. Do not remove the inner
blade washer.
 Wipe a drop of oil onto the inner blade washer and the
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 upper blade guard and onto shoulder
of inner washer. The blade teeth point downward at the
front of saw as shown in figure 13.
 Replace the outer blade washer. The double "D" flats on
the blade washers align with the flats on the 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.
