The up/down motor features a spring-loaded belt design. Belt tension is automatically
maintained and requires no adjustment. Replace the belt when adequate belt tension can
no longer be obtained.
WARNING!
Always secure the saw head with a 5/16" chain
with at least 1900 lbs. working load capacity before remov-
ing the up/down motor belt. The cutting head may fall,
causing severe injury or death.
Periodically check the belt for wear. Replace any damaged or worn belts as needed.
6.
Check the up/down gearbox oil level. Add a synthetic gear oil such as Mobil SHC 634 as
needed.
Drain and refill the gearbox
with 40 ounces of oil after every 5000 hours of sawmill opera-
tion or every 2 years, whichever comes first.
Wood-Mizer offers replacement gear oil in 8 ounce bottles.
7.
Inspect the up/down motor brushes every 750 hours of operation. Remove brush dust
and replace the brushes if they worn to a length of 5/8” or shorter.
CAUTION!
Do not operate the up/down system if the motor
brushes are worn shorter than 5/8”. Damage to the
up/down motor may result.
