5. Safety instructions

NOTE

contain all general safety rules for power tools which, in accordance with the applicable standards, require to be listed in the operating instructions. Accordingly, some of the rules listed may not be relevant to this tool.

5.1 General Power Tool Safety Warnings

WARNING

Read all safety warnings and all instructions.

Failure to follow the warnings and instructions may result in electric shock, fire and/or serious injury. Save all warnings and instructions for future reference. The term “power tool” in the warnings refers to your mains-operated (corded) power tool or battery-operated (cordless) power tool.

5.1.1 Work area safety

a) Keep work area clean and well lit. Cluttered or

dark areas invite accidents.

b) Do not operate power tools in explosive atmo-

spheres, such as in the presence of flammable liquids, gases or dust. Power tools create sparks

which may ignite the dust or fumes.

c) Keep children and bystanders away while oper-

ating a power tool. Distractions can cause you to lose control.

5.1.2 Electrical safety

a) Power tool plugs must match the outlet. Never

modify the plug in any way. Do not use any adapter plugs with earthed (grounded) power tools. Unmodified plugs and matching outlets

will reduce risk of electric shock.

b) Avoid body contact with earthed or grounded

surfaces, such as pipes, radiators, ranges and refrigerators. There is anincreased riskof electric

shock if your body is earthed or grounded.

c) Do not expose power tools to rain or wet con-

ditions. Water entering a power tool will increase the risk of electric shock.

d) Do not abuse the cord. Never use the cord for

carrying, pulling or unplugging the power tool. Keep cord away from heat, oil, sharp edges or moving parts. Damaged or entangled cords

increase the risk of electric shock.

e) When operating a power tool outdoors, use an

extension cord suitable for outdoor use. Use of a cord suitable for outdoor use reduces the risk of electric shock.

f) If operating a power tool in a damp location

is unavoidable, use a residual current device (RCD) protected supply. Use of an RCD reduces

the risk of electric shock.

5.1.3 Personal safety

a) Stay alert, watch what you are doing and use

common sense when operating a power tool. Do not use a power tool while you are tired or under

the influence of drugs, alcohol or medication.

A moment of inattention while operating power tools may result in serious personal injury.

b) Use personal protective equipment. Always

wear eye protection. Protective equipment such as dust mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal injuries.

c) Prevent unintentional starting. Ensure the

switch is in the off‐position before connecting to power source and/or battery pack, picking up or carrying the tool. Carrying power tools with

your finger on the switch or energising power tools that have the switch on invites accidents.

d) Remove any adjusting key or wrench before

turning the power tool on. A wrench or a key left attached to a rotating part of the power tool may result in personal injury.

e) Do not overreach. Keep proper footing and bal-

ance at all times. This enables better control of the power tool in unexpected situations.

f) Dress properly. Do not wear loose clothing or

jewellery. Keep your hair, clothing and gloves away from moving parts. Loose clothes, jewellery

or long hair can be caught in moving parts.

g) If devices are provided for the connection of

dust extraction and collection facilities, ensure these are connected and properly used. Use of

dust collection can reduce dust-related hazards.

5.1.4 Power tool use and care

a) Do not force the power tool. Use the correct

power tool for your application. The correct

power tool will do the job better and safer at the rate for which it was designed.

b) Do not use the power tool if the switch does not

turn it on and off. Any power tool that cannot be controlled with the switch is dangerous and must be repaired.

c) Disconnect the plug from the power source

and/or the battery pack from the power tool before making any adjustments, changing accessories, or storing power tools. Such prevent-

ive safety measures reduce the risk of starting the power tool accidentally.

d) Store idle power tools out of the reach of chil-

dren and do not allow persons unfamiliar with

the power tool or these instructions to operate the power tool. Power tools are dangerous in the

hands of untrained users.

e) Maintain power tools. Check for misalignment

or binding of moving parts, breakage of parts and any other condition that may affect the power tool’s operation. If damaged, have the power tool repaired before use. Many accidents

are caused by poorly maintained power tools.

f) Keep cutting tools sharp and clean. Properly

maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.

g) Use the power tool, accessories and tool bits

etc. in accordance with these instructions, taking into account the working conditions and the work to be performed. Use of the power tool for

operations different from those intended could result in a hazardous situation.

5.1.5 Service

a) Have your power tool serviced by a qualified

repair person using only identical replacement parts. This will ensure that thesafety of the power

tool is maintained.

5.2 Hammer safety warnings

a) Wear ear protectors. Exposure to noise can cause

hearing loss.

b) Use auxiliary handle(s), if supplied with the

tool. Loss of control can cause personal injury.

c) Hold 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 electricshock.

5.3 Additional safety precautions

5.3.1 Personal safety

a) Always hold the power tool securely with both

hands on the grips provided. Keep the grips dry, clean and free from oil and grease.

b) Breathing protection must be worn if the power

tool is used without a dust removal system for work that creates dust.

c) Improve the blood circulation in your fingers by

relaxing your hands and exercising your fingers during breaks between working.

d) Avoid touching rotating parts. Switch the power

tool on only after bringing it into position at the

workpiece. Touching rotating parts, especially rotating insert tools, may lead to injury.

e) 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.

f) Children must be instructed not to play with the

power tool.

g) The power tool is not intended for use by chil-

dren, by debilitated persons or those who have received no instruction or training.

h) WARNING: Some dust created by grinding,

sanding, cutting and drilling contains chemicals known to cause cancer, birth defects, infertility or other reproductive harm; or serious and permanent respiratory or other injury.

Some examples of these chemicals are: lead from lead-based paints, crystalline silica from bricks, concrete and other masonry products and natural stone, arsenic and chromium from chemicallytreated lumber. Your risk from these exposures varies, depending on how often you do this type of work.To reduce exposure to these chemicals,

the operator and bystanders should work in a well-ventilated area, work with approved safety equipment, such as respiratory protection appropriate for the type of dust generated, and designed to filter out microscopic particles and direct dust away from the face and body. Avoid prolonged contact with dust. Wear protective clothing and wash exposed areas with soap and water. Allowing dust to get into your mouth,

eyes, or to remain on your skin may promote absorption of harmful chemicals.

5.3.2 Power tool use and care

a) 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.

b) Check that the insert tools used are compatible

with the chuck system and that they are secured in the chuck correctly.

c) 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.

5.3.3 Electrical safety

a) 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.

b) 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 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.

c) Dirty or dusty power tools which have been

used frequently for work on conductive materials should be checked at regular intervals at a Hilti Service Center. Under unfavorable cir-

cumstances, dampness or dust adhering to the surface of the power tool, especially dust from conductive materials, may present a risk of electric shock.

d) When working outdoors with an electric tool

check to ensure that the tool is connected to the electric supply by way of a ground fault circuit interrupter (GFCI) with a rating of max. 30 mA (tripping current). Use of a ground fault circuit

interrupter reduces the risk of electric shock.

e) Use of a ground fault circuit interrupter (GFCI)

with a maximum tripping current of 30 mA is recommended.

5.3.4 Work area safety

a) Ensure that the workplace is well lit. b) Ensure that the workplace is well ventilated.

Exposure to dust at a poorly ventilated workplace may result in damage to the health.

c) 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.
