Problem
Possible Causes
Likely Solutions
Decreased output. 1. Not enough air pressure and/
or air flow.
2. Obstructed on-off switch.
3. Blocked air inlet screen (if
equipped).
4. Air leaking from loose
housing.
5. Mechanism contaminated.
6. 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 switch to ensure free movement.
3. Clean air inlet screen of buildup.
4. Make sure housing is properly assembled and tight.
5. Have qualified technician clean and lubricate
mechanism. Install in-line filter in air supply as stated in
Setup: Air Supply.
6. Replace all vanes.
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. Technician
needs to disassemble tool, align parts and reassemble.
3. Replace damaged components.
4. Clean or replace valve assembly.
Follow all safety precautions whenever diagnosing or servicing the tool. Disconnect air
supply before service.
