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.

TIGHTNESS OF PARTS:
Regularly check whether all connection parts are fastened securely. Follow this procedure daily before beginning work.

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.

ORDERING SERVICE PART:
For further operational and handling information or for replacement of parts and components, contact the sales agent from where you purchased the tool, or the service division of our company, phone number 800-221-9705. * When ordering parts and components, give each part number, name, and quantities.

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.
SUGGESTED AIR LINE CONNECTION
Oil and Water Extractor should be at least 25 ft. from the compressor.
Further if possible.
