Adjusting the Drive Belt
Tension
Service Interval: Every 2 hours
Maintain proper belt tension to improve machine
performance. Engage the drive lever and ensure that
the spring extends 3 to 6 mm (1/8 to 1/4 inch). If it
does not, adjust the belt tension.
Note:
You may hear a short buzzing sound after
releasing the engagement 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.
