After running the compressor, the lubricant will be very hot. Take care when removing the drain plug
and draining the lubricant to avoid burns.
Recommended nitrox compressor lubricant is changed when the first 25 hours of use is reached, then
change lubricant in 100-hour cycles or annually.
Wear gloves when handling compressor lubricant. If contact with skin is made, wash the skin surface
with soap and water.
Always wear goggles when handling compressor lubricant. These materials can cause eye irritation. If
you accidentally get lubricant into your eyes, flush with fresh water for 15 minutes and contact a
physician if irritation develops.
Compressor lubricant should be recycled after use at a licensed facility in accordance with Federal,
State, and local regulations.
11.8 Changing the Lubricating Oil and Filter
The lubricating oil must be changed every 250 working hours or annually.
1
Every time the lubricating oil is
changed the oil filter must be changed also.
To change the oil:
•
Position a used oil receptacle with a capacity of at
least 1.2 gal (5 L) under the drain valve (a) so the oil
flows into the receptacle. If necessary, use the
supplied oil drainpipe (d), connecting the pipe fitting
to the condensate drain tap (a).
•
Open the top plug (b).
•
Remove the plug (i), open the tap (a) and drain all
the oil.
•
Unscrew the filter (c) being sure to recover the oil
1 According to Coltri specifications, a new compressor using synthetic lubricants can operate up to 1000 hours between oil changes.
At Nuvair, we prefer to have oil changed every 250 hours (or once per year, whichever interval is less) unless you are taking
advantage of an oil analysis program that confirms the oil is still good.
