Wood and light-metal dust, hot mixtures of grinding dust
and chemical materials can self-ignite under unfavourable
conditions or cause an explosion. Avoid sparking in the
direction of the dust collector as well as overheating of
the power tool and the materials being sanded, empty the
dust collector/container in time, observe the material
manufacturer's working instructions, as well as the rele-
