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
u
Remove the battery from the power tool before carry-
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
u
When fitting or changing the saw blade, wear protect-
ive gloves.
Blades are sharp and can become hot when
used for prolonged periods of time.
u
While replacing the saw blade, ensure that the saw
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 B)
Swing the lever for saw blade release (3) approx. 60° in the
direction of the arrow and hold it in place. Push the saw
blade
(1) into the saw blade receptacle (14) . Release the
lever for saw blade release again.
u
Check that it is seated securely by pulling the saw
blade.
A loose saw blade can fall out and lead to injuries.
For particular jobs, the saw blade (1) can also be flipped
180° (teeth point upwards) and refitted.
Removing the saw blade (see figure B)
u
Let the saw blade cool down before removing it. There
is a risk of injury when touching the hot saw blade.
Swing the lever for saw blade release (3) approx. 60° in the
direction of the arrow and hold it in place. Remove the saw
blade
(1) . Release the lever for saw blade release again.
Dust/Chip Extraction
Dust 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 dust can cause allergic
reactions and/or lead to respiratory infections of the user or
bystanders.
Certain dust, such as oak or beech dust, is considered carci-
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-
terials to be worked.
u
Avoid dust accumulation at the workplace. Dust can
easily ignite.
Operation
Operating modes
Pendulum action settings
