General safety rules

SAVE THESE INSTRUCTIONS

2. Work Area

2.1 Keep your work area clean and well lit. Cluttered

benches and dark areas invite accidents.

2.2 Do not operate power tools in explosive atmos-

pheres, such as in the presence of flammable liquids,

gases, or dust. Power tools create sparks which may

ignite the dust or fumes.

2.3 Keep bystanders, children and visitors away while

operating a power tool. Distractions can cause you to

lose control.

3. Electrical Safety

3.1 Grounded tools must be plugged into an outlet

properly installed and grounded in accordance with

all codes and ordinances. Never remove the ground-

ing prong or modify the plug in any way. Do not use

any adaptor plugs. Check with a qualified electrician

if you are in doubt as to whether the outlet is proper-

ly grounded. If the tools should electrically malfunc-

tion or break down, grounding provides a low resis-

tance path to carry electricity away from the user.

3.2 Avoid body contact with grounded surfaces such

as pipes, radiators, ranges and refrigerators. There

is an increased risk of electric shock if your body is

grounded.

3.3 Don’t expose power tools to rain or wet condi-

tions. Water entering a power tool will increase the risk

of electric shock.

3.4 Do not abuse the cord. Never use the cord to car-

ry the tools or pull the plug from an outlet. Keep cord

away from heat, oil, sharp edges or moving parts.

Replace damaged cords immediately. Damaged cords

increase the risk of electric shock.

3.5 When operating a power tool outside, use an out-

door extension cord marked «W-A» or «W». These

cords are rated for outdoor use and reduce the risk of

electric shock.

4. Personal Safety

4.1 Stay alert, watch what you are doing and use

common sense when operating a power tool. Do not

use a tool while tired or under the influence of drugs,

alcohol, or medication. A moment of inattention while

operating power tools may result in serious personal

injury.

4.2 Dress properly. Do not wear loose clothing or

jewelry. Contain long hair. Keep your hair, clothing,

and gloves away from moving parts. Loose clothes,

jewelry, or long hair can be caught in moving parts.

4.3 Avoid accidental starting. Be sure switch is off

before plugging in. Carrying tools with your finger on

the switch or plugging in tools that have the switch on

invites accidents.

4.4 Remove adjusting keys or wrenches before

turning the tool on. A wrench or a key that is left

attached to a rotating part of the tool may result in per-

sonal injury.

4.5 Do not overreach. Keep proper footing and bal-

ance at all times. Proper footing and balance enables

better control of the tool in unexpected situations.

4.6 Use safety equipment. Always wear

eye protection. Dust mask, non-skid safe-

ty shoes, hard hat or hearing protection

must be used for appropriate conditions.

4.7 Exercise your fingers during pauses between work

to improve the blood circulation in your fingers.

5. Tool Use and Care

5.1 Use clamps or other practical way to secure and

support the workpiece to a stable platform. Holding

the work by hand or against your body is unstable and

may lead to loss of control.

5.2 Do not force tool. Use the correct tool for your

application. The correct tool will do the job better and

safer at the rate for which it is designed.

5.3 Do not use tool if the switch does not turn it on or

off. Any tool that cannot be controlled with the switch

is dangerous and must be repaired.

5.4 Disconnect the plug from the power source be-

fore making any adjustments, changing accessories,

or storing the tool. Such preventive safety measures

reduce the risk of starting the tool accidentally.

5.5 Store idle tools out of reach of children and other

untrained persons. Tools are dangerous in the hands

of untrained users.

5.6 Maintain tools with care. Keep cutting tools sharp

and clean. Properly maintained tools with sharp cut-

ting edges are less likely to bind and are easier to con-

trol.

5.7 Check for misalignment or binding of moving parts,

breakage of parts and any other condition that may

affect the tools operation. If damaged, have the tool

serviced before using. Many accidents are caused by

poorly maintained tools.

5.8 Use only accessories that are recommended by

the manufacturer for your model. Accessories that

may be suitable for one tool may become hazardous

when used on another tool.

1. WARNING!

Read and understand all instructions.

Failure to follow all instructions listed below may result

in electric shock, fire and/or serious personal injury.

Read the operating

instructions.

Always wear eye protection. Always wear protective

clothing.

Always wear protective

gloves.

Use protective

equipment.

6. Service

6.1 Tool service must be performed only by qualified

repair personnel. Service or maintenance performed

by unqualified personnel could result in a risk of injury.

6.2 When servicing a tool, use only identical replace-

ment parts. Follow instructions in the Maintenance

section of this manual. Use of unauthorized parts or

failure to follow Maintenance Instructions may create a

risk of electric shock or injury.

Check the tool each time before use.

Check the condition of the tool, the supply cord,

power plug and hoses. Don't use it if it is damaged,

incomplete or if the controls cannot be operated cor-

rectly. If parts are damaged or missing, have the tool

repaired at an authorized Hilti service center.

Use the correct insert tool.

Ensure that the core bits are equipped with the appro-

priate connection end for the chuck system in use and

that they are locked in position correctly in the chuck.

Use only the recommended original Hilti accessories

and auxiliary equipment.

Use the tool only for the purposes for which it is intended.

Apply a safe working method.

Avoid unfavourable body positions. Always ensure

that you have a safe and stable stance. Always hold

the tool in both hands when it is in use. Always use

the side handle. Ensure that the side handle is fitted

correctly and tightened securely .

Hold the tool securely when drilling and pay attention

at all times. Switch the tool off if you are distracted

from your work.

When the tool is in use, always guide the supply

cord away from the tool to the rear.

Never carry the tool by the supply cord. Don't unplug

the tool by pulling on the supply cord. Don't expose

the supply cord to heat, oil or sharp edges. If the sup-

ply cord becomes damaged while working, don't touch

it – unplug the power plug immediately.

Check that the blades of the plug and supply cord are

clean and dry before it is connected. Unplug the sup-

ply cord form the power socket before cleaning.

Drilling through reinforcing bars

Obtain permission from the

architect or site engineer

before drilling through rein-

forcing bars. Drilling through

steel is indicated by slow progress and clear water at

the core bit.

Take care to avoid concealed cables and pipes.

Concealed electric cables or gas and water pipes

present a serious hazard if damaged while you

are working. Accordingly, check the area in

which you are working beforehand (e.g. using

a metal detector). Avoid contact between your body

and grounded objects such as pipes or radiators. Exter-

nal metal parts of the tool may become live, for exam-

ple, when an electric cable is drilled into inadvertently.

The power to cables (or water, gas etc. in pipes) locat-

ed where drilling work is to take place must be switched

off.

Avoid unintentional starting.

Do not carry the tool with your finger on the control

switch while it is connected to the power supply. Check

that the tool is switched off and that the trigger switch

lockbutton is released before connecting it to the pow-

er supply or before connecting the supply cord to the

tool. Disconnect the plug from the power socket when

the tool is not in use, e.g. during pauses between work,

before maintenance and when changing insert tools.

Keep the electric tool and insert tools in good

condition.

Follow the care and maintenance instructions and

replace insert tools in good time. Never operate the

tool when it is dirty or wet. Dust or dampness on the

surface of the tool make it slippery and difficult to hold

and may, under unfavourable conditions, present a risk

of electric shock.

Repairs to the tool may be carried out only by an autho-

rized electrical specialist using original Hilti spare

parts. Failure to observe this point may result in dam-

age to the tool or present a risk of accident. According-

ly, if necessary, have the tool repaired at a Hilti service

center or authorized Hilti repair workshop.

When setting anchors, follow all anchor instal-

lation instructions and applicable testing / inspec-

tion regulations.

Store the tool in dry area if it is not in use.
