AIR FILTER ELEMENT
The air filter should be inspected regularly (refer to the SERVICE/
MAINTENANCE CHART) and the element replaced when the
restriction indicator lamp illuminates. The dust collector box(es) should
be cleaned daily (more frequently in dusty operating conditions) and
not allowed to become more than half full.
The safety element should be renewed every 2000 hours or every
other main filter element change, whichever comes first.
Removal
Clean the exterior of the filter housing and remove the filter element
by releasing the nut.
If the safety element is to be renewed, thoroughly clean the interior
of the filter housing prior to removing the safety element.
Inspection
Check for cracks, holes or any other damage to the element by
holding it up to a light source, or by passing a lamp inside.
Check the seal at the end of the element and replace if any sign of
damage is evident.
Reassembly
Assemble the new element into the filter housing ensuring that the
seal seats properly.
Secure the element in the housing by hand tightening the nut.
Assemble the dust collector box parts, ensuring that they are
correctly positioned.
Before restarting the machine, check that all clamps are tight.
VENTILATION
Always check that the air inlets and outlets are clear of debris etc.
COOLING FAN DRIVE
Periodically check that the fan mounting bolt in the fan hub has not
loosened. If, for any reason, it becomes necessary to remove the fan
or re-tighten the fan mounting bolt, apply a good grade of commercially
available thread locking compound to the bolt threads and tighten to
the torque value shown in the TORQUE SETTING TABLE later in this
section.
This compressor is equipped with a variable speed fan clutch that
requires no periodic maintenance.
The fan belt(s) should be checked regularly for wear and correct
tensioning.
FUEL SYSTEM
The fuel tank should be filled daily or every eight hours. To minimise
condensation in the fuel tank(s), it is advisable to top up after the
machine is shut down or at the end of each working day. At six month
intervals drain any sediment or condensate that may have
accumulated in the tank(s).
FUEL FILTER MAINTENANCE
This compressor is equipped with 2 fuel filters in series to be
replaced at every 500 hr interval or sooner if required.
1. Primary Fuel Filter / Water Separator (30 microns).
2. Final Fuel Filter / Water Separator (3 microns).
Primary Fuel Filter / Water Separator
Mounted to the lifting structure on the separator tank side of the
compressor , this filter is capable of separating water from fuel and will
filter solid contaminants to 30 microns in size.
To be checked daily for the presence of water and drained if
required.
Replace:
Unscrew the fuel filter assembly from the head, remove
the plastic bowl and install on the new filter while taking care all seals
are in place.
Final Fuel Filter / Water Separator
The final fuel filter (3 micron) is mounted on the engine. For
maintenance details, refer to the engine section of this manual.
CAUTION:
Never remove and replace element(s) when the machine
is running.
CAUTION:
If inspection reveals damage to the main element, the
safety element
must
be replaced.
CAUTION:
Safety elements must not be cleaned or re-used.
CAUTION:
NEVER clean by blowing air inwards.
WARNING: The Primary filter elements may be filled with the
appropriate quality of fuel from a clean source. NEVER fill the
Final fuel filter before installing.
The correct procedure would be to fill Primary filters with clean
fuel, leave the Final filter empty and prime the system using the
hand prime pump on the Primary filter head.
