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.
2.1.2 Hammer safety warnings
Safety instructions for all operations
▶ Wear ear protectors. Exposure to noise can cause hearing loss.
▶ Use auxiliary handle(s), if supplied with the tool. Loss of control can cause personal injury.
▶ Hold the power tool by insulated gripping surfaces, when performing an operation where the
cutting accessory may contact hidden wiring or its own cord. Cutting accessory contacting a "live"
wire may make exposed metal parts of the power tool "live" and could give the operator an electric
shock.
Safety instructions when using long drill bits with rotary hammers
▶ Always start drilling at low speed and with the bit tip in contact with the workpiece. At higher
speeds, the bit is likely to bend if allowed to rotate freely without contacting the workpiece, resulting in
personal injury.
▶ Apply pressure only in direct line with the bit and do not apply excessive pressure. Bits can bend
causing breakage or loss of control, resulting in personal injury.
2.1.3 Additional safety instructions
Personal safety
▶ Modification of the tool is not permitted.
▶ Keep the grips dry, clean and free from oil and grease.
▶ Check that the side handle is fitted correctly and tightened securely. Always hold the tool securely
with both hands on the grips provided.
▶ Wear a dust mask if the tool is operated without a dust removal system.
▶ Improve the blood circulation in your fingers by relaxing your hands and exercising your fingers
during breaks between working.
▶ The tool is not intended for use by debilitated persons who have received no special training.
▶ Keep the tool out of reach of children.
▶ Avoid touching rotating parts. Switch the power tool on only after bringing it into position at the
workpiece. Touching rotating parts, especially rotating drill bits or other accessories, may lead to injury.
▶ Always lead the supply cord and extension cord away from the tool to the rear while working. This
helps to avoid tripping over the cord while working.
▶ Dust from material such as paint containing lead, some wood species, minerals and metal may
be harmful. Contact with or inhalation of the dust may cause allergic reactions and/or respiratory
diseases among operators or bystanders. Certain kinds of dust such as oak and beech wood dust
are classified as carcinogenic, especially in conjunction with additives for wood conditioning (chromate,
wood preservative). Material containing asbestos may be worked on only by specialists. Use a dust
removal system that is as effective as possible. To achieve a high level of dust collection, use a
suitable vacuum cleaner of the type recommended by Hilti for wood dust and/or mineral dust and
which is designed for use with this tool. Ensure that the workplace is well ventilated. Observe
national regulations applicable to the materials you intend to work with.
▶ In the event of a power failure or interruption in the electric supply, switch the 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 power tool
may become live, for example, when an electric cable 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.
