7/124 - 10/104, 10/124 - 14/114, 14/84
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.
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 and oil filter element should be changed at the engine
manufacturer's recommended intervals. Refer to the Engine Operator
Manual. The Tier 4 engine in this compressor requires engine
lubricating oil to ensure proper Aftertreatment System operation and
engine durability. Doosan Tier 4 Premium Engine Oil is recommended.
Refer to the Engine Operator Manual for engine oil specifications.
ENGINE LUBRICATING OIL SPECIFICATION
Refer to the Engine Manufacturer's Manual or Lubrication Specification
list.
ENGINE OIL FILTER ELEMENT
The engine oil and oil filter element should be changed at the engine
manufacturer’s recommended intervals. Refer to the Engine Operator
Manual.
The Tier 4 engine in this compressor requires engine lubricating oil to
ensure proper Aftertreatment System operation and engine durability.
Doosan Tier 4 Premium Engine Oil is recommended. Refer to the
Engine Operator Manual for engine oil specifications.
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.
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.
RUNNING GEAR WHEEL BEARINGS
Wheel bearings should be packed with heavy duty wheel bearing
grease every 6 months.
Wheel bearings should be greased per the Maintenance Schedule in
this manual. The type of grease used should conform to specifications
below:
Grease
Thickener Type Lithium Complex
Dropping Point 215°C (419°F) Minimum
Consistency NLGI No.2
Additives EP, Corrosion & Oxidation Inhibitors
Viscosity Index 80 Minimum
TYRES/TYRE PRESSURE
See the GENERAL INFORMATION section of this manual.
BRAKES
Check and adjust the brake linkage at 500 miles (850km) then every
3000 miles (5000km) or 3 months (whichever is the sooner) to
compensate for any stretch of the adjustable cables. Check and adjust
the wheel brakes to compensate for wear.
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.
CAUTION:
Check the wheel nut torque 20 miles (30 kilometres) after
refitting the wheels (Refer to the TORQUE SETTING TABLE later in
this section).
