Maintenance - Schneider Airsystems Air Master Serie Manual De Instrucciones

BEFORE CARRYING OUT TYPE OF INTERVENTION INSIDE THE MACHINE:
• Stop the compressor using the OFF key (not using the emergency button).
• Remove the current using the external wall-mounted switch
• Close the line tap.
• Make sure there is no compressed air inside the oil-separator tank by turning tap A in an
anti-clockwise direction and allowing the air to flow out completely (fig.9) .
AFTER THE FIRST 100 HOURS
• Check the oil level and top-up using the same type of oil if necessary.
• Check screw tightness: in particular, electric power contact screws.
• Visually check tightness of connections.
• Check the environmental temperature
EVERY 100 HOURS
Check oil (fig.10)
• It is recommended to check the oil level every 100 hours of work.
• Always discharge the air from the oil-separator tank before topping-
up: open the tap slowly A until all air has escaped and then tighten (fig.9).
• The maximum oil level is considered when it touches the inside of the inlet
well D. The warning device C is used to indicate the approach to the minimum
allowed level.
• When carrying out this check, if the warning C does not result
COMPLETELY "full" it is recommended to top-up the oil through inlet well D, until
the maximum level is reached.
• About 1 litre of oil is required to top-up from the minimum to the
maximum.
EVERY 500 HOURS
Cleaning of the air suction filter (fig.11)
• Clean the air filter using compressed air, acting from the inside towards the outside.
Control for any tears against the light: in this case replace the filter.
• The filtering cartridge and the lid must be mounted carefully in order not to allow the passage
of dust inside the compression unit.
• After the third cleaning intervention replace the air filter (max. every 1500 hours).
EVERY 1000 HOURS
Check transmission belt tension (fig.12)
An appropriate measuring device is required to carry out this control, which allows to precisely
establish the degree of tension of the belt by means of a frequency measurement. Operate as
follows:
Disassemble the rear panel
• Place the measuring device microphone near to the belt in the
point indicated by "test" (about halfway) and strike the belt using a
wrench.
• Read the value measured and if it is different from the values
indicated in table 1, adjust the tension:
Higher value = belt too taught
Lower value = belt too loose
• Act in the following way:
Loosen the 4 screws (C) until the screw compressor support plate
can be moved, loosen the counter-nut (B) and turn the screw (A) in a
clockwise direction to increase the tension and in an anti-clockwise
direction to decrease it. Re-block the counter nut (B) and the screws
(C) before checking the frequency value again. Repeat the operation
until the optimal value has been obtained.
Once the desired value has been reached, block all components and
re-mount the rear panel before re-starting the compressor.
