SECTION B – PAGE 28
B.7 COMPRESSOR OPERATION
B.7a Startup
CAUTION: Do not operate the compressor at ambient temperatures
exceeding 35

C/95

F as this may cause overheating. Ensure that
adequate ventilation is available duri ng operation. Make sure exhaust
fan in cabinet is on.
SAFETY

Do not adjust the pressure switch to a higher pressure than the factory
set pressure.

Do not in any way block or prevent the normal functioning of the safety
relief valve on the receiver.

The valve is factory set and the sealing must never be broken. Only
connect pneumatic equipment suitable for maximum pressure indicated.

Do not touch compressor motor during operation as there is a risk of burn
due to high temperature (approximately 80

C/176

F).

Do not direct airflow at head or body.
1.
Start the compressor using the ON/OFF switch on the pressure switch.
The compressor will automatically switch off at the preset pressure. If the
motor does not start it may be due to pressure in the receiver, and the
motor will then start automatically when the pressure reduces to
approximately 6 bar/87 PSI.
CAUTION: The compressor oil may be aggressive towards certain
gasket materials used in pneumatic equipment. We recommend
Teflon, Viton, etc.. Do not use polycarbonate filter bowls. Contact
GBR Systems Corporation if you need further information.
HANDLING
• always keep the compressor in a vertical position as oil may run out of
the intake filter.
B.7b Fault finding and Repair
IMPORTANT!
1. Switch off and disconnect main power to the machine before removing
any parts from the compressor.
2. Empty air receiver of air before dismantling any parts of compressor
unit’s pressure system.
1. Compressor does not start:
a) No power from mains. Check fuses and plug.
b) Breakage or loose joints in electrical connections
c) The starting relay is defective. Contact GBR Systems Corporation.
d) The pressure switch is defective and does not switch on the compressor.
e) The thermal protection has switched off the compressor due to
overheating. When cooled, the compressor will automatically turn on at a
suitable operation temperature. Go through the points in section E.
f) Pressure in the air receiver is too high for activation of the pressure
switch. The pressure switch makes circuit only when pressure has
dropped to preset start pressure. Empty the air receiver.
g) The compressor has not been emptied of air and there is backpressure
on the piston. Dismount and check relief valve. The backpressure may be
due to a leaking non-return valve causing the compressed air in the
