SAFETY SETUP Troubleshooting Problem Insufficient fastener depth. Fasteners drive too deeply. Tool cycles without firing fastener. Frequent jamming. Severe air leakage. (Slight air leakage is normal, especially on older tools.) Possible Causes 1. Incorrect tool depth setting. 2. Not enough air pressure. 3. Incorrect lubrication or not enough lubrication. 4. Blocked air inlet screen (if equipped). 5. Mechanism contaminated. 1. Incorrect tool depth setting. 2. Too much air pressure. 1. Jammed fastener. 2. Tool empty. 3. Incorrect fasteners used. 4. Magazine dirty or not lubricated properly. 5. Insufficient air flow. Incorrect nail type. 1. Cross‑threaded housing components. 2. Loose housing. 3. Damaged valve or housing. 4. Dirty, worn or damaged valve. Likely Solutions 1. Adjust depth setting, if available. 2. 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 maximum air pressure. 3. Lubricate using air tool oil and grease according to directions. 4. Clean air inlet screen of buildup. 5. Have qualified technician clean and lubricate mechanism. Install in-line filter in air supply as stated in Initial Set Up: Air Supply. 1. Adjust depth setting, if available. 2. Reduce air supply pressure (PSI). 1. Clear jammed fastener according to Clearing Jams instructions. 2. Reload with correct fasteners. 3. Empty, then reload with correct fasteners. 4. Clean and lubricate magazine and pusher. 5. Check for loose connections and make sure that air supply is providing enough air flow (CFM) and pressure (PSI) to the tool's air inlet. Do not exceed maximum air pressure. Confirm nail collation type, diameter, angle, type, and length. Correct as needed. 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. 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.

Troubleshooting
Problem
Possible Causes
Likely Solutions
Insufficient
fastener depth.
1. Incorrect tool depth setting.
2. Not enough air pressure.
3. Incorrect lubrication or
not enough lubrication.
4. Blocked air inlet screen
(if equipped).
5. Mechanism contaminated.
1. Adjust depth setting, if available.
2. 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 maximum air pressure.
3. Lubricate using air tool oil and grease
according to directions.
4. Clean air inlet screen of buildup.
5. Have qualified technician clean and lubricate
mechanism.
Install in-line filter in air supply
as stated in Initial Set Up: Air Supply.
Fasteners drive
too deeply.
1. Incorrect tool depth setting.
2. Too much air pressure.
1. Adjust depth setting, if available.
2. Reduce air supply pressure (PSI).
Tool cycles
without firing
fastener.
1. Jammed fastener.
2. Tool empty.
3. Incorrect fasteners used.
4. Magazine dirty or not
lubricated properly.
5. Insufficient air flow.
1. Clear jammed fastener according to
Clearing Jams instructions.
2. Reload with correct fasteners.
3. Empty, then reload with correct fasteners.
4. Clean and lubricate magazine and pusher.
5. Check for loose connections and make sure that
air supply is providing enough air flow (CFM)
and pressure (PSI) to the tool’s air inlet.
Do not exceed maximum air pressure.
Frequent
jamming.
Incorrect nail type.
Confirm nail collation type, diameter, angle,
type, and length.
Correct 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.
3. Replace damaged components.
4. Clean or replace valve assembly.
