MAINTENANCE
Regular maintenance insures trouble-free operation. Your new compressor represents the finest engineering and construction available. However, even
the finest machinery requires periodic maintenance. A good maintenance program will add years of service to your air compressor. The following is recommended as
a minimum maintenance program. For your protection, disconnect power supply after each day’s operation and drain air from system before performing any
maintenance.
OIL TABLE
For maximum performance and service life, we recommend using ROLAIR Premium Quality compressor oil.

*Check and re-torque (see chart on pg. 12) only after pump has completely cooled to room temperature.
**Always make sure crankcase vent (breather) is free and unobstructed when changing or checking oil.
MAINTENANCE HINTS:
1) Use a soap/water solution to check for air leaks.
2) Never clean filters with a flammable solvent.
3) Re-torque head bolts only after pump has cooled.
4) Move motor 1/4" and roll belts back on to increase belt tension on electric units.
5) Never weld on air tank(s).
6) Use heat to loosen Loctite seal on drain valves, engine pulleys and flywheels before attempting to remove.
