f Dress properly. Do not wear loose clothing or jewel-

lery. Keep your hair, clothing and gloves away from

moving parts. Loose clothes, jewellery or long hair can be

caught in moving parts.

f If devices are provided for the connection of dust ex-

traction and collection facilities, ensure these are con-

nected and properly used. Use of dust collection can re-

duce dust-related hazards.

Power tool use and care

f 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.

f 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.

f 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.

f Store idle power tools out of the reach of children 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.

f Maintain power tools. Check for misalignment or bind-

ing 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.

f Use the power tool, accessories and tool bits etc. in ac-

cordance 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.

Service

f Have your power tool serviced by a qualified repair per-

son using only identical replacement parts. This will en-

sure that the safety of the power tool is maintained.

Hammer Safety Warnings

f Wear ear protectors. Exposure to noise can cause hear-

ing loss.

f Use auxiliary handle(s), if supplied with the tool. Loss

of control can cause personal injury.

f Hold the tool by the insulated gripping surfaces when

performing operations where the application tool or

the screw could contact hidden wiring or its own power

cord. Contact with a “live” wire will also make exposed

metal parts of the power tool “live” and shock the operator.

Products sold in GB only: Your product is fitted with a

BS 1363/A approved electric plug with internal fuse (ASTA

approved to BS 1362).

If the plug is not suitable for your socket outlets, it should be

cut off and an appropriate plug fitted in its place by an author-

ised customer service agent. The replacement plug should

have the same fuse rating as the original plug.

The severed plug must be disposed of to avoid a possible

shock hazard and should never be inserted into a mains sock-

et elsewhere.

Products sold in AUS and NZ only: Use a residual current de-

vice (RCD) with a rated residual current of 30 mA or less.

Additional Safety and Working

Instructions

f Observe correct mains voltage! The voltage of the pow-

er source must agree with the voltage specified on the

nameplate of the machine. Power tools marked with

230 V can also be operated with 220 V.

f Use appropriate detectors to determine if utility lines

are hidden in the work area or call the local utility com-

pany for assistance. Contact with electric lines can lead

to fire and electric shock. Damaging a gas line can lead to

explosion. Penetrating a water line causes property dam-

age or may cause an electric shock.

f Firmly tighten the auxiliary handle, hold the machine

firmly with both hands while working and keep proper

footing and balance at all times. The machine is securely

guided with both hands.

f Secure the workpiece. A workpiece clamped with clamp-

ing devices or in a vice is held more secure than by hand.

f For drilling without impact in wood, metal, ceramic and

plastic as well as for screwdriving, tools without SDS-plus

are used (e.g., drills with cylindrical shank). For these

tools, a keyless chuck or a key type drill chuck are re-

quired.

f The quick change chuck is automatically locked. Check the

locking effect by pulling the quick change chuck.

f Inserting SDS-plus Drilling Tools: Check the latching by

pulling the tool.

f Replace a damaged dust protection cap immediately.

The dust protection cap largely prevents the penetration of

drilling dust into the tool holder during operation. When in-

serting the tool, pay attention that the dust protection cap

is not damaged.

f Dusts from materials such as lead-containing coatings,

some wood types, minerals and metal can be harmful to

one’s health and cause allergic reactions, lead to respi-

ratory infections and/or cancer. Materials containing as-

bestos may only be worked by specialists.

– As far as possible, use a dust extraction system suita-

ble for the material.

– Provide for good ventilation of the working place.

– It is recommended to wear a P2 filter-class respirator.

Observe the relevant regulations in your country for the

materials to be worked.
