Disconnect the air supply before servicing
Problem
Possible Causes
Likely Solutions
Decreased output. 1. Not enough air pressure and/
or air flow.
2. Obstructed trigger.
3. Incorrect lubrication or
not enough lubrication.
4. Blocked air inlet screen
(if equipped).
5. Air leaking from loose housing.
6. Mechanism contaminated.
7. Vane wear or damage.
1. Check for loose connections and make sure that
air supply is providing enough air flow (CFM)
at required pressure (PSI) to the tool's air inlet.
Do not exceed maximum air pressure.
2. Clean around trigger to ensure free movement.
3. Lubricate using air tool oil and grease
according to directions.
4. Clean air inlet screen of buildup.

during use.
1. Incorrect lubrication or
not enough lubrication.
2. Worn parts.
1. Lubricate using air tool oil and grease
according to directions.
2. Have qualified technician inspect internal
mechanism and replace parts as needed.
Severe air leakage.
(Slight air leakage
is normal,
especially on
older tools.)
1. Cross-threaded housing
components.
2. Loose housing.
3. Damaged valve or housing.
4. Dirty, worn or damaged valve.
1. Check for incorrect alignment and uneven gaps.
If cross-threaded, disassemble and
replace damaged parts before use.
2. Tighten housing assembly. If housing cannot tighten
properly, internal parts may be misaligned.
