Vibration total values a (triax vector sum) and uncertainty K

determined according to EN 62841-2-6:
The vibration level and noise emission value given in these
instructions have been measured in accordance with a
standardised measuring procedure and may be used to com-
pare power tools. They may also be used for a preliminary
estimation of vibration and noise emissions.
The stated vibration level and noise emission value repres-
ent the main applications of the power tool. However, if the
power tool is used for other applications, with different ap-
plication tools or is poorly maintained, the vibration level
and noise emission value may differ. This may significantly
increase the vibration and noise emissions over the total
working period.
To estimate vibration and noise emissions accurately, the
times when the tool is switched off or when it is running but
not actually being used should also be taken into account.
This may significantly reduce vibration and noise emissions
over the total working period.
Implement additional safety measures to protect the oper-
ator from the effects of vibration, such as servicing the
power tool and application tools, keeping their hands warm,
and organising workflows correctly.
Assembly
Remove the battery from the power tool before carry-
u
ing out work on the power tool (e.g. maintenance,
changing tool, etc.). The battery should also be re-
moved for transport and storage. There is risk of injury
from unintentionally pressing the on/off switch.

Changing the Tool
The dust protection cap largely prevents the penetration of
drilling dust into the tool holder during operation. When in-
serting the tool, make sure that the dust protection cap 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.
Fitting the adapter (see figure A)
Remove the application tool.
Insert the adapter into the holder (1). Turn the locking ring
(9) until it audibly engages.
Inserting the SDS plus Application Tool into the Adapter
(see figure B)
The SDS-plus drill chuck enables you to change the applica-
tion tool easily and conveniently without needing to use ad-
ditional tools.
– Insert the application tool all the way into the holder of
the locking sleeve.
– Check the latching by pulling the tool.
Removing the Application Tool (see figure C)
Push back the locking sleeve and remove the application
tool.
Swivelling the Auxiliary Handle (see figure H)
You can swivel the auxiliary handle (11) to any angle for a
safe work posture that minimises fatigue.
– Turn the lower gripping end of the auxiliary handle (11)
anticlockwise and swivel the auxiliary handle (11) into
the required position. Then, turn the lower gripping end
of the auxiliary handle (11) clockwise to retighten.
Make sure that the retaining strap of the auxiliary handle
slots into the corresponding groove of the housing.
