Before Use - Hilti DX860-ENP Operating Instructions Manual

Check the tool for possible damage. Protective devices
●
and any parts that may have suffered slight damage
should be checked for correct operation and func-
tionality before further use. Damaged safety devices
or other damaged parts must be replaced or repaired
properly by an authorized repair workshop unless oth-
en
erwise indicated in the operating instructions.
Always hold the tool securely and at right angles to

fastener being deflected by the working surface.
Never use a tool that is incomplete, damaged or mal-
●
functioning.

●
combination for the job on hand. Failure to use the
correct combination of these items may result in dam-
age to the tool and/or unsatisfactory fastening quality.
Never use worn or damaged pistons and do not tam-
●
per with or modify the piston.
Use only fasteners of a type approved for use with the
●
tool.
5.8 Thermal hazards
Allow the tool to cool down. Always wear gloves if the
●
tool is dismantled for cleaning or maintenance before
it has been allowed to cool down.
Do not exceed the recommended fastener driving rate.
●
The tool may otherwise overheat.
The tool must be allowed to cool down if melting of
●
the plastic cartridge strip is observed.
Do not dismantle the tool while it is still hot. If this
●
cannot be avoided, wear protective gloves when dis-
mantling the tool.

the used cartridge strip from the tool. The (partly) used
cartridge strip must then be disposed of suitably in
order to prevent further use or misuse of any unfired
