

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.



Keep cutting tools sharp and clean. 

Properly maintained 

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



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



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



Wear ear protectors. 

Exposure to noise can cause hear-

ing loss.



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

Loss 

of control can cause personal injury.



Hold power tool by insulated gripping surfaces, when 
performing an operation where the cutting accessory 
may contact hidden wiring or its own cord. 

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.



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 
authorised 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 
socket elsewhere.

Products sold in AUS and NZ only:

 Use a residual current 

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

Additional Safety and Working In-
structions



Observe the mains voltage! The voltage of the power 
source must correspond with the data on the type plate 
of the machine.



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 ex-
plosion. Penetrating a water line causes property damage.



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.



Secure the workpiece. 

A workpiece clamped with clamp-

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



Select the correct operating mode and the suitable ap-
plication tool for the material to be worked.



Insert the SDS-max application tool: 

Check the latching 

by pulling the tool.



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.



Dust 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 res-
piratory infections and/or cancer.

 Materials containing 

asbestos may only be worked by specialists.

–

As far as possible, use a dust extraction system suitable 
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.



If the application tool should become blocked, switch 
the machine off. Loosen the application tool.



Before switching on the power tool, make sure that the 
application tool moves freely. 

When switching on with a 

blocked drilling tool, high torque reaction can occur.



To save energy, only switch the power tool on when us-
ing it.



Always wait until the machine has come to a complete 
stop before placing it down. 

The tool insert can jam and 

lead to loss of control over the power tool.



Restarting Protection

In chiselling mode, the restarting protection prevents un-
controlled starting of the machine after a power failure.

–

To 

restart the operation

, switch the On/Off switch  to 

the Off position and start the machine again.

Symbols

The following symbols are important for reading and under-
standing the operating instructions. Please take note of the 
symbols and their meaning. The correct interpretation of the 
symbols will help you to use the machine in a better and safer 
manner.

Vibration Damper (GBH 12-52 DV)

The integrated vibration damper reduces occurring vibra-
tions.
