Selecting drill chucks and tools
For hammer drilling and chiselling, you will need SDS max
tools, which insert into the SDS max drill chuck.
Changing the Tool
The dust protection cap (3) largely prevents the penetration
of drilling dust into the tool holder during operation. When
inserting the tool, make sure that the dust protection cap (3)
does not become damaged.
Replace a damaged dust protection cap immediately.
u
It is recommended that you have use an after-sales
service for this.
Changing the Tool (SDS max)
Inserting the Application Tool (see figure B)
With the SDS-max tool holder, you can change the applica-
tion tool simply and easily without additional aids.
– Clean and lightly grease the insertion end of the applica-
tion tool.
– Insert the application tool into the tool holder while turn-
ing it until it locks automatically.
– Check the latching by pulling the tool.
Removing the application tool (see figure C)
– Push the locking sleeve (4) back and remove the applica-
tion tool.
Dust/Chip Extraction
The dust from materials such as lead paint, some types of
wood, minerals and metal can be harmful to human health.
Touching or breathing in this dust can trigger allergic reac-
tions and/or cause respiratory illnesses in the user or in
people in the near vicinity.
Certain dusts, such as oak or beech dust, are classified as
carcinogenic, especially in conjunction with wood treatment
additives (chromate, wood preservative). Materials contain-
ing asbestos may only be machined by specialists.
– Use a dust extraction system that is suitable for the ma-
terial wherever possible.
– Provide good ventilation at the workplace.
– It is advisable to wear a P2 filter class breathing mask.
The regulations on the material being machined that apply in
the country of use must be observed.
Avoid dust accumulation at the workplace. Dust can
u
easily ignite.
Operation
Start-up
Ensure that the cover (11) of the Bluetooth
u
Module GCY 42 is closed during operation. This will pre-
vent dust from getting in.
