to the recommended torque (refer to the
TORQUE SETTING TABLE
later in this section).
Reconnect all hoses and tubes to the separator tank cover plate.
Replace the compressor oil (refer to
LUBRICATION
later in this
section).
CAUTION:
Start the machine (refer to PRIOR TO STARTING and
STARTING THE UNIT in the OPERATING INSTRUCTIONS section
of this manual) and check for leakage before the machine is put back
into service.
COMPRESSOR OIL COOLER AND ENGINE RADIATOR
When grease, oil and dirt accumulate on the exterior surfaces of the oil
cooler and radiator, the efficiency is impaired. It is recommended that
each month the oil cooler and radiator be cleaned by directing a jet of
compressed air, (carrying if possible a non
−
flammable cleaning
solvent) over the exterior core of the cooler/radiator. This should
remove any accumulation of oil, grease and dirt from the exterior core
of the cooler so that the entire cooling area can radiate the heat of the
lubricating and cooling oil/water into the air stream.
WARNING: Hot engine coolant and steam can cause injury. When
adding coolant or antifreeze solution to the engine radiator, stop
the engine at least one minute prior to releasing the radiator filler
cap. Using a cloth to protect the hand, slowly release the filler cap,
absorbing any released fluid with the cloth. Do not remove the
filler cap until all excess fluid is released and the engine cooling
system fully depressurised.
WARNING: Follow the instructions provided by the antifreeze
supplier when adding or draining the antifreeze solution. It is
advisable to wear personal protective equipment to prevent skin
and eye contact with the antifreeze solution.
AIR FILTER ELEMENTS
The air filter should be inspected regularly (refer to the
SERVICE/MAINTENANCE CHART
) and the element replaced when
the restriction indicator shows red or every 6 Months (500 hours),
whichever comes first. The dust collector box(es) should be cleaned
daily (more frequently in dusty operating conditions) and not allowed to
become more than half full.
Removal
CAUTION:
Never remove and replace element(s) when the machine
is running.
Clean the exterior of the filter housing and remove the filter element
by releasing the nut.
Reassembly
Assemble the new element into the filter housing ensuring that the
seal seats properly. Secure element by tightening nut.
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 bolts in the fan hub have
not loosened. If, for any reason, it becomes necessary to remove the
fan or re
−
tighten the fan mounting bolts, 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.
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).
Refer to MAINTENANCE CHART.
FUEL FILTER WATER SEPARATOR
The fuel filter water separator contains a filter element which should
be replaced at regular intervals (see the
MAINTENANCE CHART
).
CHARGE AIR COOLER PIPEWORK
Inspect all hoses and clips on the charge cooler pipe work.
Engine damage will occur if the charge cooling system leaks.
HOSES
All components of the engine cooling air intake system should be
checked periodically to keep the engine at peak efficiency.
At the recommended intervals, (see the
MAINTENANCE CHART
),
inspect all of the intake lines to the air filter, and all flexible hoses used
for air lines, oil lines and fuel lines.
Periodically inspect all pipework for cracks, leaks, etc. and replace
immediately if damaged.
ELECTRICAL SYSTEM
WARNING: Always disconnect the battery cables before
performing any maintenance or service.
Check the security of electrical terminals on the switches and relays
i.e. nuts or screws loose, which may cause local hot spot oxidation
.
Inspect the components and wiring for signs of overheating i.e.
discolouration, charring of cables, deformation of parts, acrid smells
and blistered paint.
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.
