Tensioning the Belts
DANGER!
Always shut off the motor and allow all moving
parts to come to a complete stop before removing any
guards or covers. Failure to do so may result in serious
injury.
WARNING!
Do not for any reason adjust the engine drive
belts with the machine running. Failure to do so may result
in serious injury.
NOTE!
Never apply belt dressing as this will damage the
belt and cause early failure.
1.
Check the drive belt for wear every 8 hours of operation and more frequently during the
first 24-48 hours of operation. Tension or replace as necessary. Tension should be 1/2"
deflection with 9 lbs of force for new belts or 1/2" deflection with 6 lbs of force for used
belts.
See figure 4-6.
To tension the drive belt:
Unbolt and open the blade drive side removable guard.
Loosen the motor mounting nut securing the adjustment nut.
Use the adjustment bolt as shown below to move the motor mount up or down until
the belt is properly tensioned.
