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.
