Emptying the dust container

-CAUTION-

●Dust may be released into the air when

emptying the dust removal module. ● Dust may be harmful to the respira-

tory system.

●Wear breathing protection.

-NOTE-

Hold the dust removal module so that the dust removal adaptor faces upwards.

1.Unplug the supply cord from the electric socket.

2.Press the two buttons on the dust removal module (one on each side) simultaneously.

3.Pull the dust container downwards away from the tool.

4.Empty the dust out of the container by tapping it light- ly or, alternatively, use a vacuum cleaner to clean out the container (wear breathing protection).

3.1.6Care and maintenance

We recommend use of compressed air and a cloth for
cleaning the dust removal module. Do not use water, oil,
	en
grease or cleaning agents.
3.1.7 Changing and cleaning the filter
Change the filter if it becomes defective or if so badly
soiled that cleaning is no longer possible. Disassemble
it to facilitate thorough cleaning. Especially after cutting
plaster or plasterboard (drywall panel), the filter should
be cleaned thoroughly to ensure no loss of suction power
by the dust removal system. Clean the filter carfully, using
compressed air or a vacuum cleaner.
