Dust Extraction

!WARNING Do not drill into metal with the dust extraction system

mounted. Hot metal chips can self-ignite or ignite parts of the dust extraction system.

! CAUTION	Do not drill into wood with
	dust extraction system

mounted. Wood chips are typically too large and will clog the dust channel.

!WARNING 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.
