Blade Wheel Belts
1.
Check the blade wheel belts for wear. Replace belts as necessary. Rotating the belts every 50 hours
will give you longer belt life. Use only B57 belts manufactured by Goodyear or Browning.
2.
Periodically check all belts for wear. Replace any damaged or worn belts as needed.
4.7
Up/Down System
1.
Adjust the up/down chain tension as needed. Measure chain tension, with the saw head all the way
to the top of the vertical mast. Secure the saw head with a chain at the top or shim it underneath.
Find the chain adjusting bolt at bottom part of the mast. Loosen the nut on the bolt and move the
sprocket down until there is about 1” (2.5cm) total deflection in the center of the chain with a 5 Ib.
(2.3kg) deflection force.
WARNING!
Always secure the cutting head with a chain or brace
before adjusting the up/down chain. The cutting head may fall, causing
severe injury or death.
