DANGER
Always hold the power tool securely with both hands
on the grips provided. Keep the grips dry, clean
and free from oil and grease.
7.1 Preparing for use
CAUTION
Wear protective gloves when changing insert tools
as the insert tools get hot through use and they may
have sharp edges.
CAUTION
When changing insert tools, take care to handle the
locking mechanism correctly. You may otherwise
risk pinching your fingers.
CAUTION
Avoid body contact with the guide tube as this part
gets hot through use of the power tool.
7.1.1 Fitting the insert tool 45
NOTE
Use an insert tool of a length suitable for your body
height.
1. Disconnect the mains plug from the power outlet.
2. Check that the connection end of the chisel is
clean and lightly greased. Clean it and grease it if
necessary.
3. Check that the chuck and locking bar are clean
and undamaged.
4. Push the insert tool into the chuck and pivot the
retaining bar to locking position A for insert tools
with a collar or to locking position B for insert
tools with a groove (position the chisel so that
the groove is facing locking position B).

end (with collar and groove) can be locked in
position A or B, as desired.
5. Check that the chisel has engaged correctly by
pulling it.
7.1.2 Removing the chisel

Do not lay a hot insert tool down on flammable
materials. This could cause the material to ignite,
resulting in a fire.

2. Open the locking bar by pivoting it approx. 90°.
3. Pull the chisel out of the chuck.
7.2 Operation

Wear eye protection and protective gloves. Wear
breathing protection if no dust removal system is
used. Splintering material presents a risk of injury to
the eyes and body.

The work generates noise. Wear ear protectors.
Exposure to noise can cause hearing loss.

Take care to stand in a secure position, especially
when chiseling breaches in floors, walls or ceilings,
and wear protective gloves and safety footwear.
The power tool may pull you off balance if you break
through suddenly.
CAUTION
Improve the blood circulation in your fingers by
relaxing your hands and exercising your fingers
during breaks between working.

Take care to ensure that the locking bar is in the
correct position in accordance with the information
provided in the operating instructions and check that
the insert tool is held securely (check by pulling the
