2.3 Additional safety instructions
Personal safety
▶ Use the product only when it is in technically faultless condition.
▶ Never tamper with or modify the product in any way.
▶ Apply appropriate safety measures at the opposite side of the workpiece in work that involves breaking
through. Parts breaking away could fall out and / or fall down causing injury to other persons.
▶ Check that the side handle is fitted correctly and tightened securely. Always hold the tool with both
hands on the grips provided. Keep the grips dry, clean and free from oil and grease.
▶ For this product, use only Hilti chisels with the TE-H connection end.
▶ Change the chisel only when the power tool is in the horizontal position, never when it is vertical.
▶ Push the chisel into the chuck until it engages with an audible click and the yellow warning ring is no
longer visible.
▶ Check that the chisel is correctly engaged. ATTENTION: A chisel not securely engaged in the chuck can
unexpectedly lead to dangerous situations!
▶ Start this product only when it is in the working position, not in a transport position!
▶ Take breaks between working and do physical exercises to improve the blood circulation in your fingers.
Exposure to vibration during long periods of work can lead to disorders of the blood vessels and nervous
system in the fingers, hands and wrists.
▶ The product is not intended for use by children, by debilitated persons or by persons who have received
no instruction or training.
▶ Keep the power tool out of reach of children.
▶ Before starting work, check the hazard class of the dust that will be produced when working. Use an
industrial vacuum cleaner with an officially approved protection classification in compliance with locally
applicable dust protection regulations.
▶ Use a dust removal system and suitable mobile dust extractor whenever possible. Dust from materials
such as lead-based paint, certain types of wood and concrete/masonry/stone containing quartz, minerals
or metal can be harmful to health.
▶ Make sure that the workplace is well ventilated and, where necessary, wear a dust mask 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, such as oak and beech
dust, are classified as carcinogenic, especially in conjunction with additives for treating wood (chromate,
wood preservative). Only specialists are permitted to handle material containing asbestos.
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 can become live, presenting a risk of electric shock, if you
accidentally damage an electric cable.
▶ Check the supply cord of this product 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. Unplug the supply cord 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 by Hilti Service. 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
electricity supply. This will prevent accidental restarting when power returns.
