Dust/Chip Extraction
f 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-treat-
ment additives (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
materials to be worked.
f Prevent dust accumulation at the workplace. Dusts can
easily ignite.
Troubleshooting
Maintenance and Service
Maintenance, Cleaning and Storage
f Before any work on the machine (e. g. maintenance,
changing the tool, etc.) as well as during its transport
and storage, lock the On/Off switch in the off position.
There is danger of injury when the On/Off switch is unin-
tentionally actuated.
f Always remove the blade before any work on the ma-
chine.
f For safe and proper working, always keep the machine
and ventilation slots clean.
Clean the saw blade holder preferably with compressed air or
a soft brush. Remove the saw blade from the power tool for
this. Ensure proper operation of the saw blade holder by ap-
plying a suitable lubricant.
Heavy contamination of the machine can lead to malfunc-
tions. Therefore, do not saw materials that produce a lot of
dust from below or overhead.
Store the power tool in a secure, dry place, out of the reach of
children.
Do not place other objects on the power tool.
