Recommendations for Optimal Handling of the
Battery
Protect the battery against moisture and water.
Only store the battery within a temperature range of −20 to
50 °C. Do not leave the battery in your car in the summer, for
example.
Occasionally clean the ventilation slots on the battery using a
soft brush that is clean and dry.
A significantly reduced operating time after charging indic-
ates that the battery has deteriorated and must be replaced.
Follow the instructions on correct disposal.
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.

Inserting/changing the saw blade
When fitting or changing the saw blade, wear protect-
u
ive gloves. Blades are sharp and can become hot when
used for prolonged periods of time.
While replacing the saw blade, ensure that the saw
u
to
blade receptacle is free of material residue, e.g. wood
or metal chips.
Selecting the saw blade
You will find an overview of recommended saw blades at the
end of these operating instructions. Only use saw blades
with a 1/2" universal shank. The saw blade should not be
longer than required for the intended cut.
Inserting the saw blade (see figure A)

Capacity
saw blade receptacle (10). Release the locking sleeve again.
60–100 %
Check that it is seated securely by pulling the saw
u
30–60 %

For particular jobs, the saw blade (1) can also be flipped
0–5 %
180° (teeth point upwards) and refitted.
Removing the Saw Blade (see figure B)

Dust/Chip Extraction
80–100 %
Dust from materials such as lead-containing coatings, some
60–80 %
wood types, minerals and metal can be harmful to one's
40–60 %
health. Touching or breathing-in the dust can cause allergic
20–40 %
reactions and/or lead to respiratory infections of the user or
5–20 %
bystanders.
Certain dust, such as oak or beech dust, is considered carci-
0–5 %
nogenic, especially in connection with wood-treatment ad-
ditives (chromate, wood preservative). Materials containing
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 ma-
