Blade Wheel Belts
1.
Rotate the blade wheel belts and check them for wear. Rotating the belts every 50 hours
will give you longer belt life. Replace belts as necessary. Use only B57 belts manufac-
tured 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 head all the
way to the top of the vertical mast. Secure the carriage with a chain at the top, or shim it
underneath. Find the chain adjusting bolt at the bottom of the mast. Loosen the nut on the
bolt and move the sprocket down until there is about 1" (2.5 cm) total deflection in the
center of the chain with a 5 lb. (2.3 Kg) deflection force.
WARNING!
Always secure the cutting head with a chain or
a brace before adjusting the up/down chain. The cutting
head may fall, causing severe injury or death.
See Figure 4-3.
