OPERATING
8. Slightly rotate the outer flange and blade in
the opposite direction of the blade rotation
to eliminate backlash (looseness) between
parts.
9. Place the wedge lock washer onto the
blade shaft bolt and insert the bolt into the
blade shaft through the center of the outer
flange.
10. Tighten the bolt by hand. Slowly lower the
saw, if necessary, until the blade just
touches the ground.
11. Tighten the bolt again, using the wrench, to
125 ft-lb (170 Nm) minimum to secure the
outer flange and blade.
12. Remove the detent pin from the guard
hinge and pivot the front of the guard down
over the blade to secure.
13. If replacing the front of the guard, fit the
front and back of the blade guard together.
Place the bolt through the center of the
guard hinge and tighten the lock nut to the
other end of the hinge bolt to secure the
guard together.
NOTE: Have a second trained operator hold
the guard in place while replacing the hinge
bolt and nut
.
Removing the Blade
CAUTION
DO NOT remove a blade with the
engine running.
DO NOT pivot the front of the blade guard
up or down when removing very large
blades. Attempting to pivot the front of a
heavy guard when the guard is
positioned higher up for blade removal
makes the guard difficult to lift and/or
lower. In this situation, remove the blade
guard front instead of pivoting it.
Always secure the pivoted section of the
blade guard using the detent pin (guards
26” and up).
1. Remove the detent pin from the front guard
and pivot the front of the blade guard 180°
(fully upward) to gain access to the blade.
For guards 48” or larger, remove the lock
nut and bolt from the center of the guard
hinge. Remove the front of the guard.
NOTE: Have a second trained operator hold
the guard in place while removing the hinge
bolt and nut
.
2. On the pivoted guards, insert the detent pin
through the interlocking barrels on the top
of the guard to secure the front of the
guard.
WARNING
Failure to fully pivot and secure the front of
the guard may cause serious injuries.
3. Slowly lower the saw, if necessary, until the
blade just touches the ground.
4. Remove the blade shaft bolt using the
provided wrench.
5. Carefully remove the outer flange and
blade. Place the blade in an appropriate
storage location.
NOTE: If the outer flange is difficult to remove,
tighten screws into two of the holes on the
outer flange to help separate the outer flange
from the blade
.
6. Inspect the flange assembly and clean or
replace dirty/damaged components.
7. Carefully fit the outer flange back into the
inner flange and blade shaft.
8. Place the wedge lock washer onto the
blade shaft bolt and insert the bolt into the
blade shaft through the center of the outer
flange.
9. Retighten the blade shaft bolt to secure the
flanges.
10. Remove the detent pin (guards 26” and up)
from the guard hinge and pivot the front of
the guard down over the blade flanges to
secure.
11. If replacing the front of the guard, fit the
front and back of the blade guard together.
Place the bolt through the center of the
guard hinge and tighten the lock nut to the
other end of the hinge screw to secure the
guard together.
NOTE: Have a second trained operator hold
the guard in place while replacing the hinge
bolt and nut
.
