If the engine fails to start, refer to the MAINTENANCE section of this
manual, and to the ENGINE MANUFACTURER’S MANUAL..
.
At this point in the operation of the machine it is safe to apply full load
to the engine.
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 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: 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 whilst this
situation exists. This pressure may be relieved by slowly
operating the manual blowdown valve.
CAUTION: Never allow the machine to stand idle with pressure in the
system.
EMERGENCY STOPPING
In the event that the unit has to be stopped in an emergency,
PRESS THE EMERGENCY STOP SWITCH ON THE FRONT OF
THE MACHINE AND ENSURE THAT IT ENGAGES IN DEPRESSED
POSITION.
RE–STARTING AFTER AN EMERGENCY
Disengage emergency stop control from engaged (depressed)
position.
If the machine has been switched off because of a machine
malfunction, then identify and correct the fault before attempting to
re–start.
If the machine has been switched off for reasons of safety, then
ensure that the machine can be operated safely before re–starting.
Refer to the PRIOR TO STARTING and STARTING THE UNIT
instructions earlier in this section before re–starting the machine.
MONITORING DURING OPERATION
Should any of the safety shut-down conditions occur, the unit will
stop. These are:
.
Low engine oil pressure
.
High air discharge temperature
.
High engine water temperature
.
Low water level
.
Low fuel level.
CAUTION: To ensure an adequate flow of oil to the compressor at low
temperature, never allow the discharge pressure to fall below 3,5 bar.
DECOMMISSIONING
When the machine is to be permanently decommissioned or
dismantled, it is important to ensure that all hazard risks are either
eliminated or notified to the recipient of the machine. In particular:–
.
Do not destroy batteries or components containing asbestos
without containing the materials safely.
.
Do not dispose of any pressure vessel that is not clearly marked
with its relevant data plate information or rendered unusable by drilling,
cutting etc.
.
Do not allow lubricants or coolants to be released into land surfaces
or drains.
.
Do not dispose of a complete machine without documentation
relating to instructions for its use.
