2 Safety instructions

NOTE

The safety rules in section 2.1 contain all general safety
rules for electric tools which, in accordance with the
applicable standards, must be listed in the operating
instructions. Accordingly, some of the rules listed may
not be relevant to this tool.

2.1 General power tool safety warnings

a)

WARNING

Read all safety warnings and 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 battery­operated (cordless) power tool.

2.1.1Workareasafety

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 operat-

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

2.1.2 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. Un-

modified 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 an increased risk of electric

shock if your body is earthed or grounded.

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

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

Forward /

reverse

Location of identification data on the power tool

The type designation can be found on the type identifica­tion plate and the serial number on the side of the motor
housing. Make a note of this data in your operating in­structions and always refer to it when making an enquiry
to your Hilti representative or service department.

Type:

Generation: 02

Serial no.:

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.

2.1.3 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 turn-

ing 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

2

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.

2.1.4 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

preventive 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 main-

tained 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 opera-

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

2.1.5 Battery tool use and care

a) Recharge only with the charger specified by the

manufacturer. A charger that is suitable for one type

of battery pack may create a risk of fire when used
with another battery pack.

b) Use power tools only with specifically designated

battery packs. Use of any other battery packs may
create a risk of injury and fire.

c) When battery pack is not in use, keep it away

from other metal objects, like paper clips, coins,
keys, nails, screws or other small metal objects,
that can make a connection from one terminal to
another. Shorting the battery terminals together may

cause burns or a fire.

d) Under abusive conditions, liquid may be ejected

from the battery, avoid contact. If contact acci­dentally occurs, flush with water. If liquid contacts
eyes, additionally seek medical help. Liquid ejected

from the battery may cause irritation or burns.

2.1.6 Service

a) 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.

2.2 Hammer safety warnings

a) Wear ear protectors. Exposure to noise can cause

hearing loss.

b) Use auxiliary handles, 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. Cutting ac-

cessory contacting a "live" wire may make exposed
metal parts of the power tool "live" and could give
the operator an electric shock.

2.3 Additional safety rules

2.3.1 Personal safety

a) Modification of the machine or tampering with its

parts is not permissible.

b) Always hold the power tool securely with both

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

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 rotat-

ing insert tools, may lead to injury.

e) Activate the safety lock (forward / reverse switch

in the middle position) before storing or trans­porting the power tool.

f) The appliance is not intended for use by debili-

tated persons who have received no special train­ing. Keep the appliance out of reach of children.

g) Dust from materials, such as paint containing lead,

some wood species, concrete / masonry / stone con­taining silica, and minerals as well as metal, may be
harmful. 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 are classified as carcinogenic such as oak and
beech dust, especially in conjunction with additives
for wood conditioning (chromate, wood preservative).
Material containing asbestos must only be treated by
specialists. Where the use of a dust-extraction de-

vice is possible it shall be used. To achieve a
high level of dust collection, use a suitable dust
extractor. When indicated wear a respirator ap­propriate for the type of dust generated. Ensure
that the workplace is well ventilated. Follow na­tional requirements for the materials you want to
work with.

h) 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.

i) 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
isdamagedaccidentally.Thispresentsaseriousrisk

en

of electric shock.

j) In accordance with the applications for which it is

designed, the power tool produces a high torque.

Always use the side handle and hold the power
tool with both hands. Theusermustbeprepared

for sudden sticking and stalling of the insert tool.

k) 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.

2.3.2 Careful use of the cordless tool

a) Ensure the switch is in the off position before

inserting battery pack. Inserting the battery pack

into power tools that have the switch on invites
accidents.

b) Observe the special guidelines applicable to the

transport, storage and use of Li-ion batteries.

c) Do not expose batteries to high temperatures and

keep them away from fire. This presents a risk of

explosion.

d) Do not disassemble, squash or incinerate batter-

ies and do not subject them to temperatures over
80°C (176°F). This presents a risk of fire, explosion

or injury through contact with caustic substances.

e) Use only batteries of the type approved for use

with the applicable power tool. Use of unapproved
batteries or use of the batteries in areas of application
for which they are not approved presents a risk of
fire and explosion.

f) Do not charge or continue to use damaged bat-

teries (e.g. batteries with cracks, broken parts,
bent or pushed-in and/or pulled-out contacts).

g) If the battery is too hot to touch it may be defective.

Place the tool in a location where it can be kept
under observation, well away from flammable ma­terials, and allow it to cool down. Contact Hilti
Service after the battery has cooled down.
