Noise/Vibration Information
Sound emission values determined according to
EN 60745-2-6.
Vibration total values a (triax vector sum) and uncertainty K
h
determined according to EN 60745-2-6.
The vibration level given in this information sheet has been
measured in accordance with a standardised test given in
EN 60745 and may be used to compare one tool with anoth-
er. It may be used for a preliminary assessment of exposure.
The declared vibration emission level represents the main ap-
plications of the tool. However if the tool is used for different
applications, with different accessories or insertion tools or is
poorly maintained, the vibration emission may differ. This
may significantly increase the exposure level over the total
working period.
An estimation of the level of exposure to vibration should also
take into account the times when the tool is switched off or
when it is running but not actually doing the job. This may sig-
nificantly reduce the exposure level over the total working
period.
Identify additional safety measures to protect the operator
from the effects of vibration such as: maintain the tool and the
accessories, keep the hands warm, organisation of work pat-
terns.
Assembly
Changing the Tool
 Before any work on the machine itself (e. g. mainte-
nance, tool change, etc.) as well as during transport
and storage, remove the battery from the power tool.
There is danger of injury when unintentionally actuating
the On/Off switch.

Mounting the Adapter (see figure A)
Remove the application tool.
Insert the adapter into the mounting 1. Turn the locking ring
10 until it audibly engages.
Inserting the Application Tool into the Adapter
GFA 18-H, GHA FC2 (see figure B):
Insert the application tool all the way into the mounting 1.
Removing
GFA 18-H, GHA FC2 (see figure C):
Push back the locking sleeve and remove the tool.
Changing the position of the auxiliary handle (see
figure H)
You can swivel the auxiliary handle 9 in order to achieve a safe
work posture that minimises your fatigue.
– Turn the bottom part of the auxiliary handle 9 in antclock-
wise direction and swivel the auxiliary handle 9 to the re-
quested position. Then retighten the bottom part of the
auxiliary handle 9 by turning in clockwise direction.
Adjusting the Drilling Depth (see figure I)
The desired drilling depth X can be specified with the depth
stop.
– Press the button for the depth stop adjustment and insert
the depth stop into the auxiliary handle 9.
The knurled surface of the depth stop must face downward.
– Insert the SDS-plus drilling tool to the stop into the SDS-
plus tool holder. Otherwise, the movability of the SDS-plus
drilling tool can lead to incorrect adjustment of the drilling
depth.
– Pull out the depth stop until the distance between the tip of
the drill bit and the tip of the depth stop corresponds with
the desired drilling depth X.
