STARTING THE MACHINE
Ensure emergency stop button is reset.
WARNING: Under no circumstances should volitile fluids such
as ether be used for starting this machine.
All normal starting functions are incorporated in the key operated
switch.
Turn the keyswitch to position 1;
- The auxillary start compressor will operate to close the inlet valve.
- The wedge controller will execute a lamp test.
- The low engine oil pressure and low battery lamps will flash indicating
proper communication between wedge and engine ECM.
Inlet heater / Wait to start light
• Turn the key switch to on position 1 until the inlet heater warning
light 13 extinguishes.
NOTE: Position 2 is not used
• Turn the key switch to crank position 3 (engine start position).
• Release to on position 1 when the engine starts. The engine will
now be running at a reduced speed.
• During warm up, the engine will idle at 1500RPM. After warm up the
engine will idle at a lower speed.
OPERATING INSTRUCTIONS
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
pressure control button 15.
• 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..
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.
NOTE: As soon as the engine stops, the automatic blowdown valve
will relieve all pressure from the system,except for the discharge pipe
/ manifold area. This area should be depressurised by opening the
discharge valve, keeping clear of any airflow from it.
If the automatic blowdown valve fails to operate, then pressure
must be relieved from the system by means of the service valve(s).
WARNING: When relieving system pressure by means of the
service valve(s), a small amount of pressure will remain in the
system. No maintenance work should be carried out whilst this
situation exists. This pressure may be relieved by slowly oper-
ating the manual blowdown valve.
CAUTION: Never allow the machine to stand idle with pressure in the
system.
