an after-sales service.

Changing the Tool (SDS-plus)

Inserting SDS-plus Drilling Tools (see figure H)

The SDS-plus drill chuck allows for simple and convenient 
changing of drilling tools without the use of additional tools.

–

GBH 18V-26 F: Insert the SDS-plus quick change chuck 

2

.

–

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.

As a requirement of the system, the SDS-plus drilling tool can 
move freely. This causes a certain radial run-out at no-load, 
which has no effect on the accuracy of the drill hole, as the 
drill bit centres itself upon drilling.

Removing SDS-plus Drilling Tools (see figure I)

–

Push back the locking sleeve 

5

 and remove the tool.

Dust Extraction



Dust from materials such as lead-containing coatings, 
some wood types, minerals and metal can be harmful to 
one’s health. Touching or breathing-in the dust can cause 
allergic reactions and/or lead to respiratory infections of 
the user or bystanders.
Certain dust, such as oak or beech dust, is considered car-
cinogenic, especially in connection with wood-treatment 
additives (chromate, wood preservative). Materials con-
taining 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.



Prevent dust accumulation at the workplace. 

Dust can 

easily ignite.

Dust Extraction with GDE 18V-16 (Accessories) 
(see figure N)

A GDE 18V-16 (accessory) is required for extracting concrete 
dust and stone dust.
This dust extraction system is not suitable for dust from 
wood, metal and plastic or for dust which is harmful to one’s 
health (e.g. asbestos).
