BLADE AND GUARD ASSEMBLY
WARNING:
Do not connect to power supply until assembly is complete.
Failure to comply could result in accidental starting and
possible serious injury.
TO CHECK SAW BLADE INSTALLATION
To check the saw blade, first remove the screw holding
the throat plate in place. Remove the throat plate.
See
Figures 16 and 17.
Make sure the bevel locking lever is securely pushed to
the left. Raise the blade arbor to its full height by turning
the blade adjusting handle clockwise.
Using the smaller hex wrench, insert the flat open end into
the flats on the arbor shaft as shown. Insert the larger hex
wrench over the hex nut, and, holding both wrenches
firmly, pull the larger wrench forward to the front of the
machine to loosen and push to tighten. Make sure the
blade nut is securely tightened. Do not overtighten.
Note: Arbor shaft has left hand threads.
Check all clearances for free blade rotation.
See To Set the Scale to the Blade in the
Operation
Section. In cutting operations, the scale will be set to the
side of the blade where the cut will be measured and
made.
TO INSTALL BLADE GUARD ASSEMBLY
Move the bevel locking lever to the right for angle mode.
Slowly turn the blade adjustment handle to put the blade
at 30˚. The handle will "pop out" slightly as it engages the
clutch.
Holding the blade adjusting handle with one hand, use the
other hand to push the bevel locking lever firmly to the left
to lock the bevel angle.
Raise the blade by turning the blade adjustment handle
clockwise.
Using the small hex wrench, install the blade guard
assembly by loosening the two attachment hex nuts
enough to slide the riving knife down between the shims.
See Figure 19.
Partially retighten the two attachment
nuts. Check the blade and riving knife alignment. Make
sure riving knife clears blade by 1/8 in.
See Figure 29.
Correctly align the blade and riving knife as shown,
repeating above step as needed. Tighten attachment
nuts securely. If riving knife is not positioned correctly with
blade up, it could contact saw table when blade is lowered
and restrict blade elevation.
