20 OPERATING INSTRUCTIONS
7/26E, 7/31E, 7/41
STOPPING THE MACHINE
1. Close the service valve.
2. Allow the machine to run unloaded for a short period of time to
reduce the engine temperature.
3. Turn the start switch to the 0 (off) position.
If the automatic blowdown valve fails to operate, then pressure must be
relieved from the system by means of the service valve(s).
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.
RE-STARTING AFTER AN EMERGENCY
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.
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.
NOTE: As soon as the engine stops, the automatic blowdown valve
will relieve all pressure from the system.
CAUTION: Never allow the machine to stand idle with pressure in the
system.
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.
