Inspect & Tension Belts:
• Proper belt tension must be maintained to transmit the engine power to the cutter drum. Slipping belts will over
heat, the cutter life will be shortened and the cutting speed limited. Over tensioned belts will shorten the belt and
bearing life. 70 ft. lbs. of defl ection at the center between the pulley’s, is recommended.
!! IMPORTANT!!
After tensioning belts make sure engine is level and then tighten all mounting hardware and jam nuts.
•
On new machines and after installation of new belts, adjust belt tension after the fi rst four hours, then tension as
necessary.
• Loosen engine/motor mounting hardware slightly. (Figure 8)
• Use the two jack-screw belt tensioning bolts to adjust the
engine/motor until the belts are tight. Re-torque the mounting
hardware.
