SEPTEMBER 2003
At temperatures below 0
˚
C (32
˚
F) or if there is difficulty starting
first time:
---
open the service valve fully, with no hose connected,
---
complete starting sequence above,
---
close service valve as soon as engine runs freely,
---
do not allow the machine to run for long periods with
a service valve open,
---
allow the engine to reach the operating temperature,
---
at this point in the operation of the machine it is safe
to apply full load to the engine.
NOTE
Wear hearing protection at all times when the engine is started
with the service valve open and air is flowing from the valve.
8.4.
STOPPING THE MACHINE
Operation:
---
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.
If the automatic blowdown valve fails to operate, then pressure
must be relieved from the system by means of the service
valve(s).
CAUTION
NEVER ALLOW THE MACHINE TO STAND IDLE WITH
PRESSURE IN THE SYSTEM.
8.5.
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.
8.6.
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
8.2. PRIOR TO STARTING
and
8.3. STARTING THE
MACHINE
instructions earlier in this section before re---starting
the machine.
8.7.
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.
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
(51 psi).
8.8.
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.
