ROUTINE MAINTENANCE
This section refers to the various components which require
periodic maintenance and replacement.
The SERVICE/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 INFORMATION section of this manual.
For any specification or specific requirement on service or
preventative maintenance for the engine, refer to the Engine
Manufacturer’s Manual.
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 discharge valve, whilst keeping clear of any airflow
from it.
MINIMUM PRESSURE VALVE – WHEN FITTED
NOTE: Pressure will always remain in the part of the system
between the minimum pressure valve and the discharge valve
after operation of the auto blowdown valve.
This pressure must be relieved by carefully:
(a) Disconnecting any downstream equipment.
(b) Opening the discharge valve to atmosphere.
(Use hearing protection if necessary).
. the machine cannot be started accidently or otherwise, by
posting warning signs and/or fitting appropriate anti–start
devices.
. all residual electrical power sources (mains and battery) are
isolated.
Prior to opening or removing panels or covers to work
inside a machine, ensure that:–
