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.
INSTALLING THE BLADE
See Figure 12.
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
hex 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.
Rotate lower blade guard up and loosen the blade bolt
cover screw. Rotate blade bolt cover up and back to
expose the hex bolt.
Depress and hold the spindle lock button and rotate the
hex bolt until the spindle locks.
Using the wrench provided, loosen and remove the hex
bolt.
NOTE: The hex bolt has left-hand threads. Turn hex bolt
clockwise to loosen.
Remove the laser guide or outer blade washer, and the
blade. Do not remove the inner blade washer.
Wipe a drop of oil onto the inner blade washer and the
laser guide or 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.
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.
