Power tool use and care
▶ Do not force the power tool. Use the correct power tool for your
application. The correct power tool will do the job better and safer at
the rate for which it was designed.
▶ Do not use the power tool if the switch does not turn it on and off.
Any power tool that cannot be controlled with the switch is dangerous
and must be repaired.
▶ Disconnect the plug from the power source and/or remove the
battery pack, if detachable, from the power tool before making any
adjustments, changing accessories, or storing power tools. Such
preventive safety measures reduce the risk of starting the power tool
accidentally.
▶ Store idle power tools out of the reach of children and do not
allow persons unfamiliar with the power tool or these instructions
to operate the power tool. Power tools are dangerous in the hands of
untrained users.
▶ Maintain power tools and accessories. Check for misalignment or
binding of moving parts, breakage of parts and any other condition
that may affect the power tool's operation. If damaged, have the
power tool repaired before use. Many accidents are caused by poorly
maintained power tools.
▶ Keep cutting tools sharp and clean. Properly maintained cutting tools
with sharp cutting edges are less likely to bind and are easier to control.
▶ Use the power tool, accessories and tool bits etc. in accordance
with these instructions, taking into account the working conditions
and the work to be performed. Use of the power tool for operations
different from those intended could result in a hazardous situation.
▶ Keep handles and grasping surfaces dry, clean and free from oil and
grease. Slippery handles and grasping surfaces do not allow for safe
handling and control of the tool in unexpected situations.
Service
▶ Have your power tool serviced by a qualified repair person using
only identical replacement parts. This will ensure that the safety of the
power tool is maintained.
2.2 Battery charger use and care
▶ To avoid injury, use the charger only to charge Hilti Li-ion batteries
approved for use with this charger.
▶ The location at which the charger is used should be clean, cool, dry and
protected from frost.
▶ The charger must be able to emit heat while in operation. The air vents
must therefore remain unobstructed. Do not operate the charger inside
a closed container.
