QDust suction
Warning! Fire hazard! A risk of fire exists when working with electrical appliances that have a dust collection box or can be connected to an external collection unit via a dust suction adapt- er! Under unfavourable conditions, such as flying sparks, grinding of metal or metal remnants in wood, the wood dust in the dust sack (or in the dust sack of a vacuum cleaner) can ignite.This can hap- pen especially if the wood dust has paint particles on it or is mixed with other chemical substances and the material being sanded is hot after extensive working. You should therefore avoid an overheat- ing of the items being sanded, as well of as the ap- pliance itself, and always empty the dust collection box or the dust bag of the suction unit before work pauses.
