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

Result 1 / 2
