Alternator Belt
The belt tension should be checked after the first 100 hours of operation, when the bat-
tery is not charging properly or when the alternator belt is squealing.
If the battery continues to not charge properly or the belt continues to squeal after the ini-
tial belt adjustment, replace the belt.
1.
Release the blade tension and remove the blade from the sawmill if necessary. Turn the
key switch to OFF (0) and remove the key.
2.
Remove the drive belt cover and alternator cover.
See Figure 3-1.
3.
Use a belt tension gauge to measure the belt tension. Place the gauge on the belt at the
midpoint between the two pulleys. If the belt has more than 3/16” at 9 lb. of deflection,
tighten the belt as described below.
4.
Loosen the upper pivot, lower pivot and the adjustment bolt jam nut.
5.
Turn the belt tension adjustment bolt clockwise to tighten the belt, counterclockwise to
loosen the belt. Adjust the bolt until the proper belt tension is achieved.
CAUTION!
Do not overtighten the alternator belt. Damage to the alter-
nator will occur.
