▶
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.
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.
Additional safety instructions
Personal safety
▶
Modification of the power 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 protective gloves when changing accessory tools, because the accessory tool and the tool holder get hot during use.
▶
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 power tool is not intended for use by debilitated persons who have received no special training.
▶
Keep the power 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 power 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 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 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.
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.
