INSTALLING THE BLADE
CAUTION — Improper Torque
An improperly torqued mounting bolt can cause the
inside diameter of the blade, blade shaft, and flange
bushing to quickly wear. This can result in poor cutting
characteristics or premature failure of these parts
,requiring replacement and machine “downtime.”

1. 12 In. (30.48 cm)
2. 125-175 lbs (56.7-79.4 Kg)
125-175 lbs. (56.7 -79.4 Kg) of weight applied to
the end of the blade wrench will provide 125-
175 ft. lbs. (169.5 -237.3 Nm) of torque to the
blade mounting bolt. (Figure 12.)
7. Lower the blade to the ground surface (Figure 13, Item A)
to prevent blade from spinning and tighten the mounting
bolt to 125-175 ft. lbs. (169.5 -237.3 Nm) of torque (Figure13,
Item B).

Stacking Blades for Wide Cuts
Combining or stacking blades together to make wide cuts
requires and optional bushing extension kit.
Kit #18501 allows blade stacking from .375" to .75"
thickness.
Kit #18502 allows blade stacking from .75" to 1.125"
thickness.
1. Remove existing blade (See previous section).
2. Replace the standard flange bushing, outer flange, and
mounting bolt that came with the saw with the extended
bolt and bushing and the new outer flange supplied with
the kit. Remember that the mounting bolt for the right side
of the saw has a left-hand thread while the mounting bolt
for the left side of the saw has a right-hand thread.
3. Insert the bushing and mounting bolt through the outer
flange and stack of blades. Spacers are required between
blades when stacking multiple blades. The longer bushing
and bolt allow blades to be stacked together while
maintaining proper alignment of flange bushing into blade
shaft.
4. Align flange pin through the stack of blades into the inner
flange.
5. Tighten the 5/8" Mounting Bolt to 125-175 ft. lbs. of torque.
WARNING
NEVER attempt to stack blades beyond the capacity
of the kits described here. NEVER operate the saw
without blade guards in place.
WARNING
The operator must match the diamond blade diameter
to the proper blade guard size. See Table 7.
