Maintenance
1.
Grease the up/down gear reducer shaft bearing with a NLGI No. 2 grade lithium grease
every 1000 hours of operation.
See Figure 5-12.
2.
Adjust the up/down belt as needed. Remove the up/down housing cover. To tighten the
belt, loosen the motor mount nuts. Pull the motor upward so there is 3/8" (9.5 mm) deflec-
tion with a 7 lb. (3.2 Kg) deflection force. Retighten the motor mount nuts. Replace the
drive pulley cover.
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.
