This is clearly indicated by circular sparking, rotat-
ing with the diamond cutting disc.
In this case, interrupt the cutting process and allow
the diamond cutting disc to cool by running the
machine for a short time at maximum speed with
no load.
Noticeably decreasing work progress and circular
sparking are indications of a diamond cutting disc
that has become dull. Briefly cutting into abrasive
material (e. g. lime-sand brick) can resharpen the
disc again.
Information on Structures
Slots in structural walls are subject to the Standard
DIN 1053 Part 1, or country-specific regulations.
These regulations are to be observed under all cir-
cumstances. Before beginning work, consult the
responsible structural engineer, architect or the
construction supervisor.
Recommendations for Optimal Handling of the
Battery
Store the battery only within a temperature range
between –20 °C and 50 °C. As an example, do
not leave the battery in the car in summer.
A significantly reduced working period after charg-
ing indicates that the battery is used and must be
replaced.
Observe the notes for disposal.
Maintenance and Service
Maintenance and Cleaning

Before any work on the machine itself (e. g.
maintenance, tool change, etc.) as well as dur-
ing transport and storage, remove the battery
from the power tool. There is danger of injury
when unintentionally actuating the On/Off
switch.

For safe and proper working, always keep the
machine and ventilation slots clean.
Please store and handle the accessory(-ies) care-
fully.
Transport
The contained lithium-ion batteries are subject to
the Dangerous Goods Legislation requirements.
The user can transport the batteries by road with-
out further requirements.
When being transported by third parties (e.g.: air
transport or forwarding agency), special require-
ments on packaging and labelling must be ob-
served. For preparation of the item being shipped,
consulting an expert for hazardous material is re-
quired.
Dispatch batteries only when the housing is un-
damaged. Tape or mask off open contacts and
pack up the battery in such a manner that it cannot
move around in the packaging.
Please also observe possibly more detailed nation-
al regulations.
Disposal
The machine, rechargeable batteries, acces-
sories and packaging should be sorted for
environmental-friendly recycling.
Do not dispose of power tools and batter-
ies/rechargeable batteries into household
waste!
