Starting
NOTICE
This unit is equipped with a battery disconnect switch which removes
power from the machine controller for long term storage. The switch is
located on the side of the engine near the battery.
This switch must be turned ON to provide power to the control panel for
starting this unit.
Close the air service valve to isolate the compressor from the compressed air tool until the
engine is warmed up.
1. Turn the keyswitch to the “ON” position (first position). All diagnostic lamps and
the LED display will light for two (2) seconds. All lamps should then go off and
ALTERNATOR NOT CHARGING and LOW ENGINE OIL PRESSURE lamps
will flash.
2. In freezing weather (below 32°F/0°C), flip HEATERS switch “ON” and wait sixty
(60 seconds). This applies heat to the control system components for easier
starting. Leave this switch “ON” while operating at these temperatures.
3. When the keyswitch is turned to “START” the engine starter will be engaged.
Do not operate the engine starter motor for more than ten (10) seconds
without allowing at least one minute cooling time between start attempts.
Extended engine starter engagement will result in starter drop-out and generate a
starter engagement time fault.
CAUTION
!
Ether is an extremely volatile, high flammable gas. Use Sparingly! If too
much is injected, the uncontrolled explosion may result in costly damage
to the engine.
4. In cold weather, as required, press the ETHER INJECT button once or twice
only while the engine is cranking. This injects a measured amount of ETHER
to the engine.
5. Following a successful start, the engine will accelerate to 1200 rpm initially,
then 1500 rpm for warm-up. Compressor discharge pressure will be maintained
at 60 psi during warm-up. After warm-up, rpm will maintain 1200 rpm idle.
6. Press the LOAD button. The engine will increase speed up to 1800 rpm until
the pressure reaches the desired set point.
After the engine has warmed up, open the service air valve to supply air to compressed air tool.
