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 contin-
ues to not charge properly or the belt continues to squeal after the initial belt adjustment,
replace the belt.
IMPORTANT!
Sawmills built prior to March 1999 were pro-
vided with a sight hole in the alternator bracket to gauge
belt tension. To achieve proper belt tension,
do not use the
sight hole.
Follow the procedure below to check the belt
tension and adjust if necessary.
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 2-1.
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 tension is less than 3/16” with 9 lb. of deflec-
