ASSEMBLY
TO CHECK SAW BLADE INSTALLATION
1. To check the saw blade, first remove the three screws
holding the throat plate in place. Remove the throat
plate.
See Figure 13.
2. 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.
3. 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.
4. Check all clearances for free blade rotation.
5. 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
1. Move the bevel locking lever to the right for angle mode.
Slowly turn the blade adjustment handle to put the blade
at 30 degrees. The handle will "pop out" slightly as it
engages the clutch.
2. 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.
3. Raise the blade by turning the blade adjustment handle
clockwise.
4. 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.
Do not remove the hex nuts.
See Figure 15. 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 27.
5. Correctly align the blade and riving knife as shown,
repeating step 4 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.
6. Blade alignment with the riving knife can be adjusted for
different blade widths. Refer to Settings and
Adjustments in the Operations Section. Before
continuing, read "To Check, Replace or Adjust the
Riving Knife and Blade Guard Assembly"
on page 19
to make sure of proper riving knife alignment.
7. Check the blade guard assembly for clearances and free
movement. Reinstall the throat plate into the opening,
lower the blade and secure the three attachment screws.
Tighten the screws securely.
