belt. To prolong belt life, proper tension
must be maintained. A loose belt will cause premature
sprocket wear and belt failure. A belt that is too tight
can cause shaft and bearing failure.
WARNING
A moving belt is very powerful and dangerous.
KEEP AWAY FROM MOVING BELT AT ALL
TIMES!
Extreme caution must be used to prevent death
or serious injury.
For the sake of safety, the belt guard cover must
always be in place when engine is running.
Before beginning to check or adjust the belt:
shut-down the machine, insure that all moving
parts have come to a halt, remove the key from
the ignition, and place the key in safekeeping.
NOTICE
When checking belt tension cutting wheel must
be free to turn. Therefore, check tension when
cutting boom is locked in the raised position,
rather than when cutting wheel is resting on the
ground.
If it is thereby determined that the belt is out of
adjustment, correct it by one of the following:
When the belt is too loose
1. Loosen the two bolts (1) holding each bearing,
enough to allow the bearings to slide easily.
2. Loosen the lock nuts (2) on the four bearing
jacking screws (3) & (4).
3. Back-off jacking screws (4) one full turn.
4. Tighten jacking screws (3) one full turn.
5. Check Poly Chain tension. If more tension is
necessary, repeat steps 3 and 4, and recheck
tension.
6. When tension is correct, tighten bearing bolts
and jacking screw lock nuts.
When the belt is too tight
1. Loosen the two bolts (1) holding each bearing,
enough to allow the bearings to slide easily.
2. Loosen the lock nuts (2) on the two bearing jacking
screws (3) & (4).
3. Back-off jacking screws (3) one full turn.
4. Tighten jacking screws (4) one full turn
5. Check Poly Chain tension. If more tension is
necessary, repeat steps 3 and 4, and recheck
tension.
6. When tension is correct, tighten bearing bolts
and jacking screw lock nuts.
Remove bolts, and remove belt guard cover . Apply a
force of 67-71 pounds to the belt at the midpoint of the
belt span. A properly adjusted belt will deflect 15/32".
If it deflects more than 15/32" belt is too loose. If it
deflects less than 15/32", belt is too tight.
