-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.
4. Push the dust removal module onto the tool and the
dust removal adaptor until it is heard to engage.
Detaching the dust removal module
1. Unplug the supply cord from the electric socket.
2. Press the two buttons on the dust removal module
(one on each side) and hold them in this position.
3. Pull the dust removal module away from the tool and
the dust removal adaptor toward the rear.
4. Release the dust removal adaptor from the tool by
pushing it downwards.
5. Push the dust removal adaptor downwards and pull it
out of the tool.
Emptying the dust container
-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).
3.1.6 Care and maintenance
We recommend use of compressed air and a cloth for
cleaning the dust removal module. Do not use water, oil,
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.
-NOTE-
The vibration emission level given in this information sheet has been measured in accordance with a standardised
test given in EN 60745 and may be used to compare one tool with another. It may be used for a preliminary asses-
sment of exposure. The declared vibration emission level represents the main applications of the tool. However if
the tool is used for different applications, with different accessories or poorly maintained, the vibration emission
may differ. This may significantly increase the exposure level over the total working period. An estimation of the
level of exposure to vibration should also take into account the times when the tool is switched off or when it is
running but not actually doing the job. This may significantly reduce the exposure level over the total working peri-
