TROUBLESHOOTING
Tool operator must carefully follow all operating instructions and
precautions to successfully operate the tool. Following is a list of
potential situations an operator may encounter and the probable causes:
• If a tool problem occurs and technical assistance is required, please
call 1-877-ITW-BRANDS (1-877-489-2726)
WARNING: Do not operate a tool that is not functioning properly.
TOOL FAILS TO FIRE
There are three causes for most all misfires.
INCONSISTENT FASTENER SETTING
The major reason for inconsistent fastening is the improper position of
the piston. There are two reasons for an improperly positioned piston:
1. Failure to completely reset the piston.
2. A missed hit of the rear button.
In both cases the barrel must be fully
extended to reset the piston.
Note: It is a good practice to fully extend the
barrel and re-chamber the load after the tool is
improperly struck causing a misfire, and after
the misfire procedure has been followed.
• Firing pin button struck
too lightly
• Firing pin button
struck off center
• Tool not completely
compressed
