ASSEMBLY
Depending on the cutting operation and the size of the
workpiece, it may be necessary to use a C-clamp instead of the
work clamp to secure the workpiece prior to making the cut.
To install the work clamp:
Place the shaft of the work clamp in either hole on the
miter table base.
Rotate the knob on the work clamp to move it in or out
as needed.
TO INSTALL THE BLADE
See Figure 12.
WARNING:
A 10 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.
Rotate lower blade guard up and loosen 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 wrench provided, 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 spindle.
The blade teeth point downward at the front of saw as
shown in figure 12.
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.
