IMPORTANT:
Before performing any maintenance
operations, disconnect the compressor from
the power supply and release all the air from
the receiver, until the pressure gauge reads
zero.
EVERY DAY:
Drain the condensate from the receiver. The
drain (H) Fig. 5. is situated on the underside
of the receiver tank for the DA25/200,
DA25/180 and on the end of the tank for the
DA6/200.
EVERY MONTH:
Clean the air suction filter using compressed
air. Replace the filter every 50 hours of use.
EVERY 100 HOURS:
Clean all the external surfaces of the pump
unit and motor. Ensure that neither the motor
fan cowling (J) or head cooling fins are
blocked or obstructed in any way. See Fig.6.
EVERY 200 HOURS:
Check the condition of the valves and replace
them if they are damaged or worn.
PRESSURE SWITCH SETTINGS (DA6/200,
DA6/201, DA25/180, DA25/200):
The delivery pressure setting can drift over
a period of time and will require periodic
adjustment. Ensure that the pressure switch
settings are correctly adjusted and maintained
at the correct level. This will help prevent
faults occurring which can result in reduced
performance and possible failure.
PRESSURE SWITCH ADJUSTMENTS
(DA6/200, DA6/201, DA25/180, DA25/200):
To adjust the pressure level at which the cut-
out and cut-in functions, remove the switch
cover and turn the pressure regulating screw
(K) clockwise to increase the level and
anticlockwise to decrease the level. See Fig.7.
WARNING:
DO NOT ADJUST THE CUT-OUT PRESSURE
ABOVE THE MAXIMUM PRESSURE AS PER
THE MACHINE SPECIFICATION.
