• 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 manual blowdown valve open and air is flowing from the valve.
Push After Warm Up
NOTE: In order to allow the machine to start at a reduced load, a valve,
which is operated by a service air switch 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 Service Air
Switch.
• At this point in the operation of the machine it is safe to apply full load to the engine.
CAUTION
!
If the engine does not start, repeat the above procedure after waiting for
a minimum of one minute.
If the engine fails to start, refer to the MAINTENANCE section of this manual, and to the
ENGINE MANUFACTURER’S MANUAL.
Dual Pressure Regulation When Fitted
Machines which operate in excess of 7 bar (100 psi) can optionally be fitting with a dual
pressure control 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 ON/OFF start switch to the 0 (off) position.
