Maintenance
Maintenance should be done after every 80 hours of use. All bolts should be checked for
loosening and thread locker added if needed. Remove all top covers for maintenance.
2.a.1 - Belt Tension
Belt tension should not need to be changed but can be checked using one of the following:
● Pluck the belt like a guitar string and measuring the frequency using a phone guitar tuner
app. Belt tension should be between 62 to 70 Hz.
● The belt should deflect 5/16” with a 30 lb force at the center of the span.
If the belt tension is wrong, use the following procedure:
● Loosen the two 3/8 bolts located behind the tensioner and next to the drum
● Adjust the belt tension from the top using the long 1⁄2-13 bolt
Tighten the 3/8 bolts and check the tension again.
● Repeat if necessary.
2.a.2 - Bearings and Bushings
It is recommended to lubricate the bearings every 80 hours of use. A high speed and
temperature lubricant (e.g. Lithium base NGLI #2) is recommended.
The bearings are shown for reference.
