Blade Drive Belt Tension
WARNING!
Do not for any reason adjust the motor/engine drive belts
with the machine running. Doing so may result in serious injury.
CAUTION!
Never apply belt dressing as this will damage the belt and
cause early belt failure.
CAUTION!
Use only belts of the same type as the original belts
installed at the factory.
1.
Check the drive belts for wear every 8 hours of operation and more frequently during the first 24-48
hours of operation. Tension or replace as necessary.
2.
A new drive belt is tensioned properly if it has 6 mm deflection with a 5 kg deflection force.
It is recommended that both belts be replaced when one of them is damaged.
To tension the drive belts properly:
Open the blade cover,
Locate and loosen the tensioning roller nut (A),
Move the tensioning roller so that the belt has the required deflection value.
