8 Troubleshooting
8.1 Remedying malfunctions after misfiring
▶ Press the nose of the tool against the working surface and pull the trigger.
▶ A click is audible, but the cartridge does not fire.
▶ Lift the tool away from the working surface. When doing so, never point the tool toward yourself
or other persons.
▶ Advance the cartridge strip manually to the next cartridge by pushing it by hand at the cartridge
feed side or, alternatively, by pulling the cartridge strip through manually to the next cartridge at
the cartridge strip exit side.
▶ Use up the remaining cartridges on the strip. The partly-used cartridge strip must then be removed
and disposed of appropriately to prevent further use or misuse of any unfired cartridges.
8.2 Clearing the jammed tool
WARNING
Risk of explosion! Cartridges may fire (explode) if handled improperly.
▶ Do not use force to remove cartridges from the fastening tool or the magazine strip.
1. Press the tool vertically down on to a solid surface, pull the triggers and listen to the resulting noise.
Result 1 / 2
A cartridge is triggered or a clicking noise is clearly audible.
▶ There is now no triggerable cartridge in the cartridge magazine of the tool.
▶ Proceed to the next step in the troubleshooting routine.
Result 2 / 2
No cartridge is triggered and no clicking noise is audible. There might be a triggerable cartridge in the
tool, but it did not trigger on account of a fault.
▶ ATTENTION! Make sure that the tool's nail discharge muzzle is not pointing toward anyone.
▶ Avoid hard impacts on the tool.
▶ Proceed to the next step in the troubleshooting routine.
2. Press the nose of the tool in a few millimeters and open the rotating sleeve → page 11.
▶ The catch is now accessible and you can open the tool.
3. Pull the catch out and hold it in this position. If the tool does not open up by itself try pulling it open,
without applying more than ordinary muscle power.
▶ ATTENTION! Make sure that the tool's nail discharge muzzle is not pointing toward anyone.
