PUSH AFTER WARM UP
NOTE:
In order to allow the machine to start at a
reduced load, a valve, which is operated by a button
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 button (
A
)
.
.
At this point in the operation of the machine it is
safe to apply
full load
to the engine.
DUAL PRESSURE WHEN FITTED
Machines which operate in excess of 7 bar (100 psi)
can optionally be fitted with a dual pressure switch
(B). This switch selects between 7 bar (100 psi) and
the machine rated pressure, cfm remains nominally
constant.
Starting and stopping are unaffected by the selection
and during normal running the selector switch may
be safely operated. Precaution must be taken to
ensure that downstream equipment is rated to suit
the available pressure.
The pressure guage indicates which setting has
been selected
.
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.
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.
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
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
(50 psi)
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.
