Troubleshooting Problem Possible Causes Insufficient fastener depth. 1. Not enough air pressure. 2. Incorrect lubrication or not enough lubrication. 3. Blocked air inlet screen (if equipped). 4. Mechanism contaminated. Likely Solutions 1. Check for loose connections and make sure that air supply is providing enough air pressure (PSI) to the tool’s air inlet. Do not exceed 110 PSI maximum air pressure. 2. Lubricate using air tool oil and grease according to directions. 3.
