5.6 General safety precautions
●
Operate the tool only as directed and only when it is
in faultless condition.
●
Use the splinter guard when the application permits.
●
If a cartridge misfires or fails to ignite, proceed as fol-
lows:
1. Keep the tool pressed against the working surface for
30 seconds.
2. If the cartridge still fails to fire, withdraw the tool from
the working surface, taking care that it is not pointed
towards your body or bystanders.
3. Manually advance the cartridge strip one cartridge.
Use up the remaining cartridges on the strip. Remove
the used cartridge strip and dispose of it in such a
way that it can be neither reused nor misused.
●
If 2–3 cartridge misfires occur in succession (with-
out clearly audible noise of the cartridge firing and the
fastener being driven with significantly less power), pro-
ceed as follows:
1. Stop using the tool immediately.
2. Disassemble the tool (see 8.3).
3. Check that the correct combination of fastener guide,
piston and fastener are used (see 6.2).
