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.
•
At this point in the operation of the machine it is safe to apply full load to the engine.
Dual Pressure Regulation When Fitted
Machines which operate in excess of 7 bar (100 psi) can optionally be fitted with a dual
pressure switch inside the unit. 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 gauge 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 pressure from the system.
If the automatic blowdown valve fails to operate, then pressure must be relieved from the
system by means of the manual blowdown 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, or push the
EMERGENCY STOP SWITCH (when fitted).
