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 removing 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 Glygoyle 460
as needed.
Drain and refill the gearbox
with 40 (1.2L) ounces of oil after every 5000 hours of sawmill
operation or every year, whichever comes first.
Wood-Mizer offers replacement gear oil in 8 ounce (0.24L) 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” (16mm) or shorter.
CAUTION!
Do not operate the up/down system if the motor brushes
are worn shorter than 5/8” (16mm). Damage to the up/down motor may
result.
The up/down system is equipped with a gas spring assist mechanism to provide improved
speed and performance. The saw head must be secured and tension released from the
assist assembly before performing any maintenance to assist components.
WARNING!
Always secure the saw head with a 5/16" (8mm) chain
with at least 1900 lbs. (860Kg) working load capacity before servicing
the up/down assist. The cutting head may fall, causing severe injury or
death.
WARNING!
Release pressure from the up/down assist prior to per-
forming any service to the assembly. Failure to do so may result in the
assembly flying apart, causing injury or damage to the equipment.
