▶
Use a dust removal system and suitable vacuum cleaner whenever possible. Dust from materials, such
as paint containing lead, some wood species, concrete/masonry/stone containing silica, and minerals as
well as metal, may be harmful.
▶
Make sure that the workplace is well ventilated and, where necessary, wear a respirator appropriate for
the type of dust generated. Contact with or inhalation of the dust may cause allergic reactions and/or
respiratory or other diseases to the operator or bystanders. Certain kinds of dust are classified as
carcinogenic such as oak and beech dust, especially in conjunction with additives for wood conditioning
(chromate, wood preservative). Material containing asbestos may be handled only by specialists.
▶
Wear protective gloves when using the power tool and when changing accessory tools. Touching the
accessory tool presents a risk of injury (cuts or burns).
▶
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.
Electrical safety
▶
Before beginning work, check the working area for concealed electric cables or gas and water pipes.
External metal parts of the power tool may give you an electric shock if you damage an electric cable
accidentally.
▶
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 tool may, under unfavorable conditions, lead to electric shock.
▶
Switch the power tool off and unplug the supply cord in the event of a power failure or interruption in the
electric supply. This will prevent accidental restarting when the electric power returns.
