Belt Maintenance
Checking and Adjusting the
Belt Tension
Service Interval: Before each use or daily
Every 2 hours
The belt tension may decrease over time. You may
need to adjust the belt within the first half hour of
operation.
Important:
Check the belt tension regularly.
Improper belt tension may cause premature belt
wear.
The belt may need adjustment if there is a constant
buzzing sound while the tines are engaged or if there
is a squealing sound when the tines are engaged and
under load.
Note:
You may hear a short buzzing sound after
releasing the drive-control lever while using the
machine. This is normal and is caused by the teeth of
the cogged belt contacting the wire belt guide to stop
rotation. You do not need to adjust the belt tension
for this.

Pull down the drive-control lever and measure
the length of the extended cable spring. The

If the belt needs adjustment, hold the lower
jam nut on the adjustable cable in place and
adjust the upper jam nut in 0.32 cm (1/8 inch)
increments. Check the tension again, and
repeat as necessary.
Note:
If the tension is incorrect and you cannot
adjust the jam nuts further, move the Z-bend end
of the cable to the next hole in the drive-control
lever as shown in
