Maintenance
Ensure the air line is shut-off and drained of air before removing this tool for service or changing sockets. This will prevent the tool from operating if the throttle is accidentally engaged.
LUBRICATION
□ An in-line filter-regulator-lubricator is recommended as it increases tool life and keeps the tool in sustained operation.
□ Regularly check and fill the in-line lubricator with air tool oil. Avoid using excessive amounts of oil.
□ Adjust the in-line lubricator by placing a sheet of paper next to the tool’s exhaust ports and holding the throttle open approximately 30 seconds. The lubricator is properly set when a light stain of oil collects on the paper.
□ If it is necessary to store the tool for an extended period of time (overnight, weekend, etc.), generously lubricate the tool through the air inlet. Run the tool for approximately 30 seconds to ensure the oil is evenly distributed throughout the tool. Store the tool in a clean and dry environment.
□ Recommended lubricants: Air tool oil or any other high grade turbine oil containing moisture absorbent, rust inhibitors, metal wetting agents, and an EP (extreme pressure) additive.

Troubleshooting
Problem
The tool runs slowly or will not operate.
Possible Cause
There is grit or gum in the tool.
The tool is out of oil.
The air pressure is low.
The air hose leaks.
The air pressure drops.
There is a worn rotor blade in the motor.
There is a worn ball bearing in the motor.
There is moisture blowing out of the tool’s exhaust.
There is water in the tank.
Solution
Flush the tool with air tool oil or gum solvent.
Lubricate the tool according to the lubrication instructions in this manual.
□ Adjust the regulator on the tool to the maximum setting.
□ Adjust the compressor regulator to the tool’s maximum setting of 90 psi.
Tighten and seal the hose fittings with pipe thread tape if leaks are found.
□ Ensure the hose is the proper size. Long hoses or tools using large volumes of air may require a hose with an I.D. of ½" or larger depending on the total length of the hose.
□ Do not use a multiple number of hoses connected together with a quick connect fitting. This causes additional pressure drops and reduces the tool power. Directly connect the hoses together.
Replace the rotor blade.
Remove and inspect the bearing for rust, dirt, and grit. Replace or clean and grease the bearing with bearing grease.
Drain the tank. (See the air compressor manual for instructions.) Lubricate the tool and run it until water is not evident. Lubricate the tool again and run for 1-2 seconds.
