user is also responsible for the replacement of components due to normal wear
and aging. Failure to adhere to proper maintenance intervals and procedures
may result in diminished performance of the product and/or accelerated wear of
components. Use fuel consumption, service hours, or calendar time, WHICH
EVER OCCURS FIRST, to determine the maintenance intervals. Products that
operate in severe operating conditions may require more frequent maintenance.
Before each consecutive interval is performed, all maintenance from the
previous interval must be performed.
6.1. Daily
NOTE: DO NOT USE THE COMPRESSOR CABINET FOR STORAGE.
a. Check and record all operating parameters to a USB drive or SD card as described in
the Description of Operations ("Daily Record").
b. Adjust or service as required or indicated.
c. Check for proper operation of the intercooler and aftercooler automatic drain valves. The
valves should pulse briefly each 1-2 second while the compressor is loaded.
The intercooler automatic drain will not operate while the compressor is unloaded. The
intercooler drain line has a check valve to prevent backflow of drained condensate while
the compressor is unloaded. Inspect the check valve for proper operation. This
compressor is also equipped with manual bypasses to the drain valves. They can be left
open if desired, which would eliminate the need to maintain the automatic drain valves.
CAUTION: Do not operate the compressor with the service valves closed to the
automatic condensate drain valves.
d. Check operation of capacity control valve by observing load/unload cycle. Press
manual unload if necessary, to unload compressor.
e. Test pilot lights by pressing LED Test key on HMI Terminal Options page.
f. Check oil level on compressor and engine.
g. Check coolant level.
h. Inspect air cleaner service indicator.
i. Drain fuel system primary filter/water separator.
6.2. Weekly
a. Inspect interior of the compressor cabinet for abnormal conditions including
excessive dust, leaks, and loose parts.
b. Drain condensate in control air filter.
c. Fuel tank water and sediment- drain as needed.
d. Air filter or oil filter must be changed if the HMI displays a filter service alert.
e. Inspect DEF filler screen, clean as needed.
f. Check battery and connections. Clean/replace as required.
