ELECTRICAL SYSTEM
When removing connectors from electrical devices and sensors,
inspect the terminals to ensure they have electrical grease on them. If
electrical grease is not present or very minimal, then add a small
amount of Doosan Part No. 22409114 electrical grease to the
terminals. Dirty and or corroded electrical terminals can be cleaned
using electrical contact cleaner.
Inspect the safety shutdown system switches and the instrument panel
relay contacts for evidence of arcing and pitting. Clean where
necessary.
Check the mechanical action of the components.
Check the security of electrical terminals on the switches and relays i.e.
loose nuts or screws, 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.
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 machine 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.
WARNING: Always disconnect the battery switch before
performing any maintenance or service.
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.
WARNING: High oil viscosity during cold start up, clogged oil
filters or valve malfunction can result in oil starvation.
