Operation & Maintenance Manual Operating Instructions
52 Book 22826226
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.
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, TURN THE KEY SWITCH
LOCATED ON THE INSTRUMENT PANEL TO THE “0” (OFF) POSITION, or push the
EMERGENCY STOP SWITCH (when fitted).
If the unit is not fitted with an emergency stop switch, rotate the start switch to the (0) off
position.
Re-Starting After an Emergency
Disengage emergency stop control from engaged (depressed) position. (IF FITTED)
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
