MAINTENANCE INSTRUCTION
LUBRICATION:
Before connection of the hose, apply 4 to 5 drops
of a good quality air tool oil at the air inlet.
After 3 to 4 hours of operation, oiling may be
necessary again.

Regularly check whether all connection parts are
fastened securely. Follow this procedure daily
before beginning work.
DISPOSAL:
Follow national legislation of waste disposal.
STORAGE:
Avoid storing the tool in a location subject to high
humidity. If the tool is left unused, the residual
moisture inside the tool can cause rust. Before
storing and after operation, oil the tool at the air
inlet with a good quality air tool oil and run it for a
short period.

SUGGESTED AIR LINE CONNECTION
The oil and water extractor should not be mounted on or near the air compressor.
The temperature of air is greatly increased during compression. As the air cools down to room
temperature, in the air line, on its way to the Air Power Tool, the moisture contained in it condenses.
Thus, for maximum effectiveness, the oil and water extractor should be mounted at some point in the
air supply system where the temperature of the compressed air in the line is likely to be lowest.
Air lines must be properly drained daily. Each low point in an air line acts as a water trap. Such points
should be fitted with an easily accessible drain. See diagram below. Pitch all air lines back towards the
compressor so that condensed moisture will flow back into the air receiver where it can be drained off.
Drain daily.
