Starting the Compressor
NOTICE Be sure to let unit warm up after starting for
smooth operation of the engine and the compressor.
Do not operate the engine at full load immediately after
it starts up. This will shorten the equipment life.
• During machine warm-up, inspect the equipment
for any loose parts, fluid leakage, and other
issues.
• Make sure that monitor lamps are off.
To start compressor:
1. Make sure discharge air pressure gauge indicates
0 psi.
2. Fully close service valve.
3. Turn starter switch ( A ) to RUN position. The glow
lamp ( B ) will turn on.
4. When the glow lamp goes out, turn the starter
switch to START position.
• Perform starter switch operation within 15
seconds.
• Make sure to wait longer than 2 minutes before
starting next operation. Failure to wait the
designated time could cause the starter motor to
overheat, and could damage it.
• If residual pressure is present in the separator
receiver tank, the residual pressure lamp ( C ) will
illuminate, and the starter will not rotate. Make
sure the residual pressure remains 0 psi (0 bar).
• According to engine cooling water temperature,
the times in the table below are required.
5. Once engine starts, leave it running to warm up
for 5 minutes. The discharge air pressure gauge
( D ) ranges from 44 to 102 psi (3 to 7 bar).
6. After warm-up is complete, open the service valve
at the outlet of compressed air, and start service
job.
