The vibration emission 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 another.
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 poorly maintained,
the vibration emission may differ. This may significantly in-
crease 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 signif-
icantly 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 hands warm, organise work patterns.
Assembly
 Before any work on the machine itself, pull the mains
plug.
Auxiliary Handle
 Operate your machine only with the auxiliary handle 5.
The auxiliary handle 5 can be set to any position for a secure
and low-fatigue working posture.
– Turn the bottom part of the auxiliary handle 5 in counter-
clockwise direction and swivel the auxiliary handle 5 to the
desired position. Then retighten the bottom part of the
auxiliary handle 5 by turning in clockwise direction.
Changing the Tool
With the SDS-max tool holder, simpler and easier tool chang-
ing is possible without additional aids.
The dust protection cap 1 largely prevents the penetration of
dust into the tool holder during operation. When inserting the
tool, pay attention that the dust protection cap
1 is not damaged.
 A damaged dust protection cap should be changed im-
mediately. We recommend having this carried out by
an after-sales service.
Inserting (see figure A)
– Clean and lightly grease the shank end of the tool.
– Push back the locking sleeve 2 and insert the tool in a twist-
ing manner into the tool holder. Release the locking sleeve
2 again in order to lock the tool.
– Check the latching by pulling the tool.
Removing (see figure B)
– Push back the locking sleeve 2 and remove the tool.
Dust/Chip Extraction
Dusts 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 dusts can cause allergic
reactions and/or lead to respiratory infections 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 contain-
ing asbestos may only be worked by specialists.
– 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 mate-
rials to be worked.
