MAINTENANCE

!WARNING: Before performing maintenance, release any remaining air pressure in the manifold by slowly pulling open the

safety relief valve (See Parts Identiﬁcation item 10) and disconnect/lockout/tagout the main power supply�

WEEKLY MAINTENANCE

■Check for any unusual noises, vibrations or consistent leaks from the solenoid valve (see Parts Identiﬁcation item

8)�

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 (see Parts Identiﬁcation item 2)�

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 item 10)

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�

!WARNING:

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�

DIGITAL AMD (see Parts Identiﬁcation item 5)

A Digital AMD is used to detect the demand for compressed air and allow the motor to start� When the demand is satisﬁed, the motor

stops� the Digital AMD is preset at the factory by C-Aire and does not require adjustment� However, if you want to make adjustments to

the Digital AMD, those instructions are on page 5�

!DANGER: Electric power always exists inside the digital AMD 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�
