Do not drill into metal with
the dust extraction system
mounted. Hot metal chips can self-ignite or
igniteparts of the dust extraction system.
Do not drill into wood with
dust extraction system
mounted. Wood chips are typically too large
and will clog the dust channel.
Your tool is equipped with
a dust canister, empty it
frequently, after completion of drilling and
before storing the tool. Be extremely
careful of dust disposal, materials in fine
particle form may be explosive.
Note: Do not use the dust extraction system
when chiselling, screwdriving or cutting threads.
The dust extraction system retracts during
operation so that the dust cap is always kept
close to surface being drilled.
The dust extraction system automatically
switches on and off with the power tool.
For maximum dust extraction efficiency, please
observe the following.
* The drill bit being used may not project
beyond the dust cap as shown in figures 13 &
14. (Example for an SDS-plus drill bit: Max.
total length approx. 160 mm, working length
approx. 100 mm).
* Pay attention that the dust cap faces flush
against the workpiece or the wall. At the same
time, this makes working at a right angle easier.
* After reaching desired drilling depth, first pull
the drill bit out of the hole and then switch the
tool off.
* Check the condition of the microfilter regularly.
Replace a damaged microfilter immediately.
