Trouble shooting
Fault Finding
1. The RM series motors are designed to perform at their rated capacities for the long periods of
time. Faults can develop for the following reasons:
(A) Lack of lubrication. This will leave to rapid wear, internal seizure, loss of power or excessive air
leakage.
(B) Faults in the air supply system:
1. failure to remove the plastic protective dust caps
2. insufficient air pressure at the motor caused by (a) supply pipe line or valve too small (b) if the
exhaust is piped away excessive back pressure due to small bore pipes (c)
compressor of insufficient capacity (d) clogged airline filter (e) the air pressure should remain at the
required pressure when the motor is operating at full potential. If the air pressure reduces considera-
bly from the stationary to the rotating conditions then the supply line or the compressed air available
is inadequate for the service operation of the motor.
The motor should always be supplied with clean moisture free and lubricated air. The better the
quality of the air the less attention will be required to the motor unit.
