▶ 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.
▶ Avoid applying an excessive amount of grease to the drill bit connection end. Grease may otherwise
be forced out of the chuck when the power tool is in operation.
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 power tool's supply cord at regular intervals and have it replaced by a qualified specialist
if found to be damaged. If the power 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
▶ Keep bystanders a safe distance away from work area. Anyone entering the work area must wear
personal protective equipment. Fragments of workpiece or of a broken accessory may fly away and
cause injury beyond the immediate area of operation.
▶ 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 protective equipment
▶ 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.
