Maintenance and inspection
▪How to carry out maintenance
•Intake filter
Blow dust off the filter with an air gun and replace if it is dirty.
•Belt tension
If the V belt makes a slipping sound at the startup, due to decrease of V belt tension, readjust the belt tension or
replace it.
If the belt tension is less than the figure in the chart below, adjust the belt tension again.
An exclusive tool is necessary to measure belt tension.
Ask our distributor to readjust belt tension when needed.
