OPERATING INSTRUCTIONS
PRIOR TO STARTING
1. Place the unit in a position that is as level as possible. The
design of the unit permits a 15 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).
CAUTION: Do not overfill either the engine or the compressor
with oil.
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.
CAUTION: Use only a No. 2–D diesel fuel oil with a minimum
octane number of 45 and a sulphur content not greater than
0,5%.
CAUTION: When refuelling:–
.
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.
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).
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.
8. Check the radiator coolant level (with the unit level).
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.
