Displays during operation
Be sure to check at times to see if screen indicates or each component of the unit are properly
working, or if there is any air-leak, oil-leak, water-leak or fuel-leak etc.
During normal operation, each indication of instruments is shown in the table below. Refer to the
table for daily checks.
The above table gives standard values. They may vary slightly depending on the operating
conditions and other factors.
When the machine is in operation under load,
check to see that the compressor's oil level
falls within the range between the lower limit
and upper limit of the level gauge if the level
is found to be insufficient, replenish the oil.
※
Keep the operation log to record constant
inspection of each component, so that trouble of
the machine can be easily discovered and
preventive measures can be taken.
Do not open the valves below listed when operating.
Separator receiver tank drain valve
Coolant drain valve
Engine oil drain valve
Oil cooler drain valve
Fuel tank drain valve
Make sure that discharge pressure always reads at least
58PSI
during operation.
If you keep operating with less than
58PSI
, it will causes less separation of lubricating
oil at oil separator, or baking caused by overheat of compressor body.
