Never operate the air compressor without protective belt guards installed. Replace damaged protective covers or guards immediately.
SAFETY WARNINGS Read and Understand all Safety Warnings before using Air Compressor Hazard Level Potential of Hazard How to Avoid Hazard Serious injury may occur from loose debris being propelled at high speeds from the compressed air stream.

SYSTEM CONTROLS (1) SAFETY RELIEF VALVE Every ROLAIR air compressor is equipped with a safety relief valve which is designed to discharge tank pressure at a predetermined setting when a systems failure occurs. Check the safety valve periodically by pulling on the ring only when the tank pressure is completely drained. The spring loaded valve should move freely within the safety valve body.
(8) PILOT UNLOADER VALVE A pilot unloader valve is used on all gas-powered units and can be used on electric air compressors to operate in a continuous manner. When the storage tank reaches the top pressure setting of the pilot valve, the air being compressed is discharged to atmosphere instead of into the storage tank. When the tank pressure drops to the low pressure setting of the pilot valve, the compressed air will be redirected to the air tank.
