PERIOD
MAINTENANCE
Daily
Check the lubricating oil level and replenish
as necessary.
Check the oil filter pressure differential.
Check the air filter pressure differential.
Check the condensate drain functionality.
First 150 hours
Change the oil filter element.
Clean the condensate strainers.
1 month
AC
Check the cooler(s) for build–up of
foreign matter. Clean if necessary by blowing
out with air.
Each 3 months
Operate the safety valves manually to verify
that the valve mechanism is functioning
correctly and that a small amount of air is
released.
Check all hoses for signs of deterioration,
cracks, hardening etc.
2000 hours
Lubricate the main motor drive end bearing.
Lubricate the main motor non–drive end
bearing.
4000 hours
Rebuild condensate solenoid valves using
field kits.
4000 hours / 6
months
Inspect the blowdown silencers and replace
if necessary.
Clean the gearcase breather.
6 months
Check the calibration of the pressure
transducers.
Change the air filter element (Replace more
frequently if local conditions require).
8000 hours
Inspect the starter contactors, replace if
required.
Replace check valve seat and spring using
field kit.
Rebuild blowdown valve using field kit.
8000 hours / 1 year
Clean the condensate strainers.
Change the lubricating oil and filter element.
Fully inspect condensate separators, all
external surfaces, and fittings. Report any
excessive corrosion, mechanical or impact
damage, leakage or other deterioration.
1 year
Remove the safety valves from the
compressor, inspect and re–calibrate.
16000 hours
Rebuild hydraulic cylinder using field kit.
4 years
Replace all hoses.
40000 hours
Replace discharge check valve.
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.
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.
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 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:–
.
anyone entering the machine is aware of the reduced level of
protection and the additional hazards, including hot surfaces and
intermittently moving parts.
.
the machine cannot be started accidentally or otherwise, by posting
warning signs and/or fitting appropriate anti–start devices.
Prior to attempting any maintenance work on a
running
machine, ensure that:–
.
the work carried out is limited to only those tasks which require the
machine to run.
.
the work carried out with safety protection devices disabled or
removed is limited to only those tasks which require the machine to be
running with safety protection devices disabled or removed.
.
all hazards present are known (e.g. pressurised components,
electrically live components, removed panels, covers and guards,
extreme temperatures, inflow and outflow of air, intermittently moving
parts, safety valve discharge etc.).
.
appropriate personal protective equipment is worn.
.
loose clothing, jewellery, long hair etc. is made safe.
.
warning signs indicating that Maintenance Work is in Progress are
posted in a position that can be clearly seen.
Upon completion of maintenance tasks and prior to returning
the machine into service, ensure that:–
.
the machine is suitably tested.
.
all guards and safety protection devices are refitted.
.
all panels are replaced, canopy and doors closed.
.
hazardous materials are effectively contained and disposed of.
