Changing the Tool

With the SDS-plus tool holder, simple and con-
venient tool changing is possible without addi-
tional aids.
As a requirement of the system, the SDS-plus 
drilling tool can move freely. This causes a cer-
tain radial run-out at no-load, which has no ef-
fect on the accuracy of the drill hole, as the drill 
bit centres itself upon drilling.
The dust protection cap 

2

 largely prevents the 

entry of drilling dust into the tool holder during 
operation. When inserting the tool, take care 
that the dust protection cap 

2

 is not damaged.

f

A damaged dust protection cap should be 
changed immediately. We recommend hav-
ing this carried out by an after-sales service.

Inserting SDS-plus Drilling Tools (see figure C)

Clean and lightly grease the shank end of the 
tool.
Insert the tool in a twisting manner into the tool 
holder until it latches itself.
Check the latching by pulling the tool.

Inserting Drilling Tools without SDS-plus 
(see figure E)
Note: 

Do not use tools without SDS-plus for 

hammer drilling or chiselling! Tools without 
SDS-plus and their drill chucks are damaged by 
hammer drilling or chiselling.
Insert the quick change keyless chuck 

12

.

Firmly hold the retaining ring of the quick 
change keyless chuck

. Open the quick 

change keyless chuck by turning the front sleeve 
in the direction of the symbol “

. Firmly hold the retaining ring of 

the quick change keyless chuck

Check the tight seating by pulling the tool.

Note: 

If the tool holder was opened to the stop, 

then the latching noise possibly may be heard 
while closing the tool holder and the tool holder 
will not close.
In this case, turn the front sleeve 

13

 once in the 

opposite direction of the arrow. Afterwards, the 
tool holder can be closed (tightened) again.
Turn the mode selector switch

Dust Extraction with the Dust Extrac-

tion Attachment (Accessory)

f

Dusts from materials such as lead-containing 
coatings, some wood types, minerals and 
metal can be harmful to one’s health. Touch-
ing or breathing-in the dusts can cause aller-
gic reactions and/or lead to respiratory infec-
tions of the user or bystanders.
Certain dusts, such as oak or beech dust, are 
considered as carcinogenic, especially in 
connection with wood-treatment additives 
(chromate, wood preservative). Materials 
containing asbestos may only be worked by 
specialists.
– Provide for good ventilation of the work-

ing place.

– It is recommended to wear a P2 filter-

class respirator.

Observe the relevant regulations in your 
country for the materials to be worked.

Mounting the Dust Extraction Attachment 
(see figure F)

For dust extraction, the dust extraction attach-
ment (accessory) is required. When drilling, the 
dust extraction attachment retracts so that the 
attachment head is always close to the surface 
at the drill hole.
