Maintenance
The following maintenance is required at specific intervals. These intervals are basedon conditions where the ambient
temperature is around 86°F. If your location is warmer or running condition is more severe, maintain within a shorter period.
During warmer conditions, shorten the period approximately 30% from our recommendation at every 9°F.
Standard maintenance period is not our warranty period.
▪Standard maintenance period
•For 115psi models (SLBE-7.5 and SLBE-10)
Maintenance is to be done according to operating hours, or period, whichever comes first.

Maintenance
▪How to carry out maintenance:
•Intake filter
Blow dust off the filter with an air gun and replace if it is dirty.
•Safety valve
Lift up the stemof the safety valve at around maximum pressure and check to see if air blows out.
•Belt tension
If the V belt makes a slipping sound at the startup, due todecrease of V belt tension, readjust the belt tension or replace it.
If belt tension is less than the figure in the chart below, adjust belt tension again.
An exclusive tool is necessary tomeasure belt tension.
Ask our distributor to readjust belt tension when needed.
