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. An inoperable safety valve could allow an
excessive amount of tank pressure to build causing the air tank to catastrophically rupture or explode.
Do not tamper with or attempt to eliminate the safety relief valve.
2. MANUAL OVERLOAD / MOTOR RESET Every ROLAIR
electric air compressor is built with manual
®
trip
overload protection. If the motor overheats, the overload sensor will
the reset button to protect the
motor. If this occurs, please allow the motor to cool for approximately five minutes. Locate and push in the
reset button. The use of an undersized or excessive length of extension cord may be the cause of
overheating. Re-evaluate the power source and gauge/length of extension cord being used. (Refer to chart
on page 8)
3. PRESSURE SWITCH Most electric air compressors are operated by the use of a pressure switch. Always
make sure the lever is in the "Off" position before plugging in the power cord. By moving the lever to the
"On/Auto" position, the compressor will start and stop automatically within the settings of the pressure
switch which are typically 105 – 130 PSI. Do not attempt to stop the compressor by unplugging the power
cord. To stop, simply move the lever to the "Off" position. The lever operates a relief valve that dumps off
head pressure and allows the compressor to restart without load the next time it is used.
4. REGULATOR – WORKING PRESSURE To adjust the output/line pressure, simply lift up on the regulator
adjustment knob and rotate clockwise to increase working pressure or counterclockwise to decrease. Push
adjustment knob back down to lock in setting. Never exceed the manufacturer's maximum allowable
pressure rating of the tool being used or item being inflated.
5. PRESSURE GAUGE(S)
Typically, most compressors are designed with a gauge to measure tank or
storage pressure and another gauge attached to the regulator that indicates output or working pressure.
6. DRAIN VALVE(S) One or more drain valves are installed to allow moisture to be drained on a daily basis
from the compressor storage tank(s). Open drains carefully and slowly to prevent scale, rust, or debris from
becoming expelled at a high rate of speed.
