ROUTINE MAINTENANCE
This section refers to the various components which require periodic maintenance and
replacement.
The MAINTENANCE CHART indicates the various components' descriptions and the intervals
when maintenance has to take place. Oil capacities, etc., can be found in the GENERAL DATA
SECTION of this manual.
For any specification or specific requirement on service or preventative maintenance for the
engine, refer to the Engine Section.
Compressed air can be dangerous if incorrectly handled. Before doing any work on the unit,
ensure that all pressure is vented from the system and that the machine cannot be started
accidentally.
If the automatic blowdown fails to operate, then pressure must be gradually relieved by
operating the manual blowdown valve. Suitable personal protective equipment should be
worn.
Ensure that maintenance personnel are adequately trained, competent and have read the
Maintenance Manuals.
Prior to attempting any maintenance work, ensure that:-
• all air pressure is fully discharged and isolated from the system. If the automatic
blowdown valve is used for this purpose, then allow enough time for it to complete
the operation.
• the discharge pipe / manifold area is depressurised by opening the service valve,
while keeping clear of any airflow from it.
WARNING
!
Pressure will remain in the system between the minimum pressure valve
and the service valve after shutdown and operation of the auto blowdown
valve.
This pressure must be relieved by :
(a) Disconnecting any downstream equipment.
(b) Opening the service valve to atmosphere.
• the machine cannot be started. Post warning signs and/or fit anti-start devices.
• Disconnect battery cables.
