of dust collection, use a suitable vacuum cleaner. When indicated, wear a respirator appropriate
for the type of dust generated. Ensure that the workplace is well ventilated. Follow national
requirements for the materials you want to work with.
▶
Before beginning the work, check the hazard classification of the dust that will be produced. Use
an industrial vacuum cleaner with an officially approved protection classification in compliance
with locally applicable dust protection regulations.
▶
Observe the national health and safety requirements.
Careful handling and use of power tools
▶
Secure the workpiece. Use clamps or a vice to secure the workpiece.
The workpiece is thus held
more securely than by hand and both hands remain free to operate the power tool.
▶
Ensure that the accessory tools used have a mounting system that is compatible with the electric
tool and that they are secured in the chuck correctly.
▶
In the event of a power failure or interruption in the electric supply, switch the power tool off,
unplug the supply cord and release the switch lockbutton (if applicable).
This will prevent accidental
restarting when the electric power returns.
Electrical safety
▶
Before beginning work, check the working area (e.g. using a metal detector) to ensure that no
concealed electric cables or gas and water pipes are present.
External metal parts of the tool may
become live, for example, when an electric power line is damaged accidentally. This presents a serious
risk of electric shock.
▶
Check the tool’s supply cord at regular intervals and have it replaced by a qualified specialist if
found to be damaged. If the tool’s supply cord is damaged it must be replaced with a specially-
prepared and approved supply cord available from Hilti Customer Service. Check extension cords
at regular intervals and replace them if found to be damaged. Do not touch the supply cord or
extension cord if it is damaged while working. Disconnect the supply cord plug from the power
outlet.
Damaged supply cords or extension cords present a risk of electric shock.
▶
Dirty or dusty power tools that have been used frequently for work on conductive materials should
be checked at regular intervals at a Hilti Service Center.
Dust (especially dust from conductive
materials) or dampness adhering to the surface of the power tool may, under unfavorable conditions,
lead to electric shock.
Work area
▶
If the work involves breaking right through, take the appropriate safety measures at the opposite
side.
Parts breaking away could fall out and / or fall down and injure other persons.
Personal safety
▶
Wear protective gloves.
The rotary hammer may get hot during use. There is a risk of injury (cutting or
burning) if the accessory tool is touched while changing it.
