Do not carry out these tasks if the compressor has only just shut down; wait for the compressor to
cool. Pressure must be drained before opening LP fill plug.
Any oil spilt during the oil/filter change could cause personnel to slip; wear protective garments and
anti-slip footwear and remove traces of oil immediately.
Both oil and filter are classified as special wastes and must therefore be disposed of in compliance
with the anti-pollution laws in force.
All maintenance work must be carried out with the compressor OFF and the power supply lead
unplugged from the main socket.
13.7 Checking the Oil Level
The oil level must be checked every five (5) working hours of the compressor. The oil
level must be between the minimum and the maximum shown on the oil level viewer
(Figure 21 and Figure 22).
If the oil level is above the maximum level:
•
Position a receptacle under the drain hose (Figure 23) so that the oil flows into
the exhausted oil receptacle.
•
Open the drain valve (a, Figure 22) and let the oil flow out until the oil level returns within the maximum
and minimum limits.
•
Close the drain valve.
If the oil level is below the minimum level:
•
Open the top fill plug (b, Figure 22).
•
Top off with oil until the level returns within the maximum and minimum limits.
•
Close the fill plug.
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.
