Operation & Maintenance Manual Operating Instructions
Starting
• Move the POWER switch to ON.
• Move Power switch to START position to crank engine. Hold switch in START
position for approximately 5 seconds after engine starts.
Do not operate the starter motor for more than 30 seconds without
allowing at least 30 seconds cooling time between start attempts.
Release Power Switch (it will automatically move to the ON position) when the engine starts
and sustains running.
• Allow engine to warm up 3 minutes.
• Press the Service Air Button. Open air service valve(s).
Cold Weather Starting
• Move power switch to the Glow Plug position and hold 10 seconds. Then turn
to start.
Exercise extreme caution when using a booster battery to start. To jump
start: Connect the ends of one booster cable to the positive (+) terminals
of each battery. Then connect one end of the other cable to the negative
(-) terminal of the booster battery and the other end to the engine block.
Not to the negative (-) terminal of the weak battery.
Stopping
Whenever the machine is stopped, air will flow back into the compressor
system from devices or systems downstream of the machine unless the
service valve is closed. Install a check valve at the machine service
valve to prevent reverse flow in the event of an unexpected shutdown
when the service valve is open.
