Lubrication Operating & Maintenance Manual

If the unit has been operated for the time/ hours mentioned above, it should be completely
drained of oil. If the unit has been operated under adverse conditions, or after long periods in
storage, an earlier change period may be necessary as oil deteriorates with time as well as by
operating conditions.
WARNING
!
High pressure air can cause severe injury or death from hot oil and flying
parts. Always relieve pressure before removing caps, plugs, covers or
other parts from pressurized air system. Ensure the following conditions
are met:
Discharge air pressure gauge reads zero (0).
No air discharging from an “open” manual blowdown valve.
An oil change is good insurance against the accumulation of dirt, sludge, or oxidized oil
products.
Completely drain the reservoir, piping, and cooler. If the oil is drained immediately after the
unit has been run for some time, most of the sediment will be in suspension and, therefore,
will drain more readily. However, the fluid will be hot and care must be taken to avoid contact
with the skin or eyes.
After the unit has been completely drained of all old fluid, close the drain valve. Add oil in the
specified quantity at the filler plug. Tighten the filler plug and run the machine to circulate the
oil. Check the oil level when unit is warm and not running. If not near the middle of the sight
tube, stop the unit and make corrections. DO NOT OVERFILL.
NOTICE

obtain extended limited airend warranty.
