MAINTENANCE
!
WARNING
: Before performing maintenance, release air pressure from the compressor using the manual drain valve (see
parts identification reference 5) and disconnect/lockout/tagout the main power supply�
WEEKLY MAINTENANCE
■
Use the manual drain valve to drain moisture from your air compressor’s tank WEEKLY!
!
CAUTION
: Open the drain valve
slowly
to release the moisture, as pressure in the tank can cause the moisture to expel
at very high velocity�
■
Check for any unusual noises, vibrations, or permanent leaks from the unloader valve�
BIANNUAL MAINTENANCE
■
TURN OFF POWER, and check and tighten all electrical connections�
■
Change air-intake filter(s)� The filter is located on the top of the compressor� Twist the top cap off of the filter
housing to access the filter�
■
Check to make sure all bolts are tight�
VALVES AND SWITCHES
PRESSURE RELIEF VALVE (safety valve - see parts identification)
Pressure-relief valves are standard on all units� Pressure-relief valves aid in preventing system failures by relieving system pressure
when compressed air reaches a determined level� Pressure-relief valves are PRESET by the manufacturer:
under no circumstances
should the setting be changed by anyone other than the manufacturer�
!
DANGER
: Pressure-relief valves are designed to protect compressed-air systems in accordance with ASME B19 safety
standards�
PRESSURE SWITCH (see parts identification)
Pressure switches are standard on all C-Aire compressors� The pressure switch detects the demand for compressed air and allows the
motor to start� When the demand is satisfied, the motor stops� Pressure switches are preset at the factory by C-Aire and do not require
adjustment�
!
DANGER
: Electric power always exists inside the pressure switch whenever the compressor is connected to a power supply�
Do not touch any electrical leads or electric components without locking out the power supply first�
