6 Double insulation
To ensure maximum safety of the user, our tools are designed and
built to satisfy applicable European standards (EN standards). Tools
with double insulation are marked by the international symbol of
a double square. These tools must not be grounded and a two‑wire
cable is sufficient to supply them with power. Tools are shielded in
accordance with EN 55014.
7 Use
The machine is designed for blowing away non‑toxic substances
(such as splinters, metal shavings, stone dust) created during cut‑
ting, drilling, sanding, or grinding.
The machine is not suitable for blowing away hot, flammable, or
explosive material.
Occasionally, the machine can also be used as a vacuum cleaner for
fine‑grained dirt or dust.
The user bears full responsibility for the consequences of using the
tool for purposes other than the above.
8 Accumulator Charging Instructions
1. Please make sure the mains voltage is the same as the volt‑
age listed on the charger's machine plate. Connect the charg‑
er [N1] to a power source. A red LED indicator [N2] will light up.
This means the charger is ready to charge. If the red LED indi‑
cator does not light up, check the connection to power supply.
