Technical Data
Torque Chart - Metric
Monthly, inspect all hardware on this equipment and engine/motor. Loose hardware can contribute to early
component failure and poor performance. Use the torque chart below as a general guideline and keep all hardware
tight.
Note: Some hardware is used to retain parts that have to move freely for correct operation of this unit. The
hardware for these items should be snug enough to prevent excessive play, yet loose enough to allow the parts to
pivot freely.
