OPERATING INSTRUCTIONS 15
7/53
PRIOR TO STARTING
1. Place the unit in a position that is as level as possible. The design
of the unit permits a 10 degree lengthways and sideways limit on
out of level operation. It is the engine, not the compressor, that is
the limiting factor.
When the unit has to be operated out of level, it is important to keep the
engine oil level near the high level mark (with the unit level).
2. Check the engine lubrication oil in accordance with the operating
instructions in the Engine Operator’s Manual.
3. Check the compressor oil level in the sight glass located on the
separator tank.
4. Check the diesel fuel level. A good rule is to top up at the end of
each working day. This prevents condensation from occurring in the
tank.
5. Drain the fuel filter water separator of water, ensuring that any
released fuel is safely contained.
6. Open the service valve(s) to ensure that all pressure is relieved
from the system. Close the service valve(s).
8. Check the radiator coolant level (with the unit level).
AIR HOSE RESTRAINT INSTALLATION
Check the air restriction indicator(s). Refer to the MAINTENANCE
section of this manual.
When starting or operating the machine in temperatures below or
approaching 0°C, ensure that the operation of the regulation system,
the unloader valve, the safety valve, and the engine are not impaired
by ice or snow, and that all inlet and outlet pipes and ducts are clear of
ice and snow.
Safety devices such as hose restraints (whipchecks)must be used to
prevent hose whipping if a connection fails. Whipchecks are to be
constructed of woven stainless steel, galvanized steel wire rope or
chain with aminimum strength adequate for the supplied pressure and
hose diameter. Whipchecks must be fastened to suitable mounting
points or shackles.
The mounts and/or shackles are to be of the same or greater strength
as the whipchecks. An engineer should be consulted about suitability
of whipchecks, mounts, mounting points, shackles and fittings as well
as strength rating of materials. Whipchecks must be used at the hose
origination, termination and each hose to hose connection.
Hoses can fail in areas other than at connecting points and require
daily inspection of the hoses for:
• Cuts, cracks or kinks
• Weakened clamps due to rust and corrosion
• Damaged connections
• Deformity
• Incorrect or incompatible components or fittings
• Any visual damage
Hoses must be selected that are rated for the application as to the
maximum pressure and temperature to be encountered as well as
compatible with the materials being conveyed inside the hose. Hoses
must be compatible with the compressor oil.
CAUTION: Do not overfill either the engine or the compressor with
oil.
CAUTION: Use only specified diesel fuels (see engine section for
details)
CAUTION: When refueling:-
• switch off the engine.
• do not smoke.
• extinguish all naked lights.
• do not allow the fuel to come into contact with hot surfaces.
• wear personal protective equipment.
7. CAUTION: Do not operate the machine with the canopy/doors in
the open position as this may cause overheating and operators to
be exposed to high noise levels.
