The following steps should be accomplished before placing
the diamond blade on the blade shaft.
1. Set the engine ON/OFF switch to the
oFF position.
2. Raise the saw to a high position by cranking the Raise/
Lower handle in a counterclockwise direction.
3. Use the Blade Nut Wrench and Blade Shaft Locking
Wrench stored on the front section of the console to
install the diamond blade.
Refer to Figure 9 when removing or installing the diamond
blade as follows.
1.
Blade guard — Raise the front half of the blade guard
to expose the blade shaft nut and outer flange.
2. Blade Nut Wrench — Remove the blade nut wrench
from the tool holder and unscrew the blade shaft nut
(right-side). This nut loosens clockwise and tightens
counterclockwise.
3. Blade Nut — Remove the blade nut. For reassembly,
Do NoT overtighten the blade nut against the outer
flange. Tighten blade nut approximately 125 - 175 ft-lbs
(169 - 237 N-m).
4. outside Blade Flange (Collar) — Ensure that the
flange face is clean and free of debris and is placed
flush against the diamond blade. Check that the drive
pin goes through the blade pin hole and seats properly
into the inner flange collar.
5. Blade pin hole — Align this hole with the drive pin
hole on the inner flange collar.
6. Diamond Blade — Ensure that the proper blade has
been selected for the job. Pay close attention to the
directional arrow on the blade, clockwise for right-side
cutting and counterclockwise for left-side cutting. The
arbor hole of the blade must match the 1-inch arbor
of the blade shaft.
7. inner Flange Collar — This flange is fixed upon the
blade shaft and is manufactured with a drive pin hole.
The inside surface of the flange must be free of debris
and must permit a tight closure on the surface of the
blade.
