10.2 BASIC MAINTENANCE AND
CHECKS – FIG. 6
Note: Remove the plug from the socket before
carrying out adjustment, servicing or maintenance.
In order to maintain the compressor to its optimum,
periodical service checks must be carried out
routinely. Allowances should be made to adjust the
time scale for machines in occasional service with
the exception of the safety valve which must be
inspected by a qualified service agent every 12
months regardless of use.
Note: Where necessary, ear defenders and safety
goggles must be worn.
Daily checks:
– Before every use check the airline/regulator/separator.
– After every use adjust the line pressure back to zero.
Monthly checks:
– Remove the foam air filter element
(10)
for cleaning or renew if necessary.
• Rinse the filter with water and soap. Make certain the element is completely dry prior
to re-fitting.
The cleaning/replacement of the air filter must be carried out more frequently if the compressor is
operating in a dusty environment.
The motor must be correctly ventilated during operation. For this reason avoid blocking the air
inlets. After use disconnect the compressor from the power supply and vacuum the ventilation slots.
If replacement of the supply cord becomes necessary, this will need to be completed by the
manufacturer or an appointed agent in order to avoid potential safety hazards.
Warning! Never attempt to run the compressor without the filter element fitted as dust or foreign
bodies can enter the pump unit resulting in serious damage.
