INSTALLING THE BLADE
The blade can be mounted on either side of the saw to
accomodate different cutting jobs. With the proper sized
blade selected, reference the following procedure to install
the new blade.
1. Raise the saw so the blade will clear the ground when
installed.
2. Remove the blade flange bolt. This bolt is LEFT-HAND
thread on the RIGHT side of the saw and RIGHT-HAND
thread on the LEFT side of the saw.
3. Verify the blade flanges are clean and not damaged. Pay
particular attention to all holes and recesses (Figure 9).
4. Taking note of the direction of rotation of the blade, (Figure
11, Item A) insert the bushing and mounting bolt through
the outer flange and blade (Figure 10).
5. Align flange pin through the blade into the inner flange.
INSTALLING THE BLADE
Ensure the flange faces are kept clean and
smooth as well as the inside diameter of the
blade shaft.
Figure 9. Inspect and Clean Flange
The blade mounting bolt on the right side of
the saw (as viewed from the operator’s
position), has a
left-hand
thread, while the
bolt on the left side of the saw has a
right-
hand
thread.
6. With the blade still off the ground, tighten mounting bolt
as tight as can be achieved until blade spins. (Figure 11,
Item B shows tightening direction for blade mounted
on RIGHT side of saw.)
WARNING — Tighten Blade Mounting Bolt
Failure to properly tighten the blade mounting bolt can
result in the bolts coming loose with the blade flange
potentially falling off the rotating blade shaft assembly.
The blade and other parts coming loose from the saw
during operation pose a high risk of serious injury or
even death!
