NOTE: In order to allow the machine to start at a reduced load, a valve,
which is operated by a service air switch located on the instrument panel,
is incorporated in the regulation system. (The valve automatically returns
to the start position when the machine is switched off and air pressure
relieved from the system).
•
Allow the engine to reach its operating temperature - then press the pressure control
button
15
.
•
At this point in the operation of the machine it is safe to apply
full load
to the engine.
CAUTION
!
If the engine does not start, repeat the above procedure after waiting for
a minimum of one minute.
If the engine fails to start, refer to the
MAINTENANCE
section of this manual, and to the
ENGINE MANUFACTURER’S MANUAL.
Stopping the Machine
•
Close the service valve.
•
Allow the machine to run unloaded for a short period of time to reduce the engine
temperature.
•
Turn the ON/OFF start switch to the
0
(off) position.
NOTE: As soon as the engine stops, the automatic blowdown valve will
relieve all pressure from the system, except for the discharge pipe/
manifold area. This area should be depressurised by opening the
discharge valve, keeping clear of any airflow from it.
If the automatic blowdown valve fails to operate, then pressure must be relieved from the
system by means of the service valve(s).
WARNING
!
WARNING: When relieving system pressure by means of the service
valve(s), a small amount of pressure will remain in the system. No
maintenance work should be carried out if this situation exists. Relieve
this pressure by opening the manual blowdown valve.
