BATTERY
Keep the battery terminals and cable clamps clean and lightly
coated with petroleum jelly to prevent corrosion.
The retaining clamp should be kept tight enough to prevent the
battery from moving.
PRESSURE SYSTEM
At 3 month intervals it is necessary to inspect the external surfaces
of the system (from the airend through to the discharge valve(s))
including hoses, tubes, tube fittings and the separator tank, for visible
signs of impact damage, excessive corrosion, abrasion, tightness and
chafing. Any suspect parts should be replaced before the machine is
put back into service.
TYRES/TYRE PRESSURE
See the GENERAL INFORMATION section of this manual.
RUNNING GEAR/WHEELS
Check the wheel nut torque 30 kilometres (20 miles) after refitting
the wheels. Refer to the TORQUE SETTING TABLE later in this
section.
The bolts securing the running gear to the frame should be checked
periodically for tightness (refer to the SERVICE/MAINTENANCE
CHART for frequency) and re-tightened where necessary. Refer to the
TORQUE SETTING TABLE later in this section.
LUBRICATION
The engine is initially supplied with engine oil sufficient for a nominal
period of operation (for more information, consult The Engine
Manufacturer's Manual).
If, for any reason, the unit has been drained, it must be re-filled with
new oil before it is put into operation.
ENGINE LUBRICATING OIL
The engine oil should be changed at the engine manufacturer's
recommended intervals. Refer to the SERVICE / MAINTENANCE
CHART.
ENGINE LUBRICATING OIL SPECIFICATION
Refer to the Engine Manufacturer's Manual or Lubrication
Specification list.
ENGINE OIL FILTER ELEMENT
The engine oil filter element should be changed at the engine
manufacturer's recommended intervals. Refer to the SERVICE /
MAINTENANCE CHART.
COMPRESSOR LUBRICATING OIL
Refer to the SERVICE/MAINTENANCE CHART in this section for
service intervals.
Completely drain the receiver/separator system including the piping
and oil cooler by removing the drain plug(s) and collecting the used oil
in a suitable container.
Replace the drain plug(s) ensuring that each one is secure.
CAUTION: Exercise extreme caution when using booster battery. To
jump battery, connect ends of one booster cable to the positive (+)
terminal of each battery. Connect one end of other cable to the
negative (-) terminal of the booster battery and other end to a ground
connection away from dead battery (to avoid a spark occurring near
any explosive gases that may be present). After starting the
compressor, always disconnect cables in reverse order.
CAUTION: Always check the oil levels before a new machine is put
into service.
NOTE:
If the machine has been operating under adverse conditions,
or has suffered long shutdown periods, then more frequent service
intervals will be required.
WARNING: DO NOT, under any circumstances, remove any
drain plugs or the oil filler plug from the compressor lubricating
and cooling system without first making sure that the machine
is stopped and the system has been completely relieved of all air
pressure
(refer to STOPPING THE UNIT in the OPERATING
INSTRUCTIONS section of this manual).
NOTE:
If the oil is drained immediately after the machine has been
running, then most of the sediment will be in suspension and will
therefore drain more readily.
CAUTION: Some oil mixtures are incompatible and result in the
formation of varnishes, shellacs or lacquers which may be insoluble.
