A set of V belts transmits rotational power to the rotor. They must be kept properly tensioned and the pulleys
aligned to obtain the expected performance and life.
To check the tension and alignment, follow this procedure:
1.
Clear the area of bystanders, especially small children.
2.
Turn machine off, stop engine, remove ignition key and place in pocket and wait for all moving parts to stop.
3.
Remove guard over belt.

Push on the belt in the center of the span. The belt should deflect approximately 1 inch (25mm) when
pushed on with about 10 lbs. force to be properly tensioned.
IMPORTANT
The belt should not slip when chipper
is being used.
