ASSEMBLY
WORK CLAMP
See Figure 12.
WARNING:
In some operations, the work clamp assembly
may interfere with the operation of the blade guard
assembly. Always make sure there is no interference
with the blade guard prior to beginning any cutting
operation to reduce the risk of serious personal injury.
The work clamp provides greater control by clamping the
workpiece to the fence. It also prevents the workpiece from
creeping toward the saw blade. This is very helpful when
cutting compound miters.
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 as needed.
TO INSTALL / REPLACE THE BLADE
See Figures 13 - 14.
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.
