manual abstract
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. REMOVING AND INSTALLING DUST EXTRACTION SYSTEM To remove dust extraction system, press and hold the dust extraction release button and pull away from tool housing (Fig. 5). To install dust extraction system, align guide grooves with the grooves in tool housing and push toward tool until you hear it lock into place (Fig. 5). MICROFILTER DUST CANISTER The integral dust extraction system collects dust in a canister supplied with your extraction system. The dust level of the dust canister can easily be checked through the transparent door (Fig. 6). For maximum efficiency, the dust canister should be emptied frequently during operation. REMOVING DUST CANISTER To remove dust canister, press the two canister release buttons and pull canister downward out of the dust extraction system (Fig. 6). CLEANING AND EMPTYING THE DUST CANISTER Before opening the dust canister, gently strike or tap it against a firm surface to loosen the dust from the microfilter. Open the transparent door and empty the dust canister. Close transparent door. Check the microfilter for damage. Replace it immediately when damaged.

CHANGING THE MICROFILTER For maximum efficiency, the microfilter should be replaced after approx. 15 hours of operation. Remove the dust canister from the dust extraction system (Fig. 6). Lift the microfilter upward and remove old or damaged filter from dust canister (Fig. 7). Insert a new microfilter into the dust canister and reinstall the dust canister (Fig. 7.) Note: If the microfilter is damaged (e.g. holes, damage to the soft sealing material), it must be replaced immediately. Working with a damaged microfilter can cause damage to the power tool. Also replace the microfilter when the vacuuming performance is insufficient, even when the dust canister is empty. FIG. 7 DUST CANISTER MICROFILTER VACUUM ADAPTER DUST CANISTER (Not included, available as accessory) For dust extraction with a vacuum cleaner, the (optional) vacuum adapter dust canister can be inserted into the dust extraction system instead of the dust canister, if required. Press the two canister release buttons and pull canister downward and remove from the dust extraction system (Fig. 6). Install vacuum adapter dust canister upward into dust extraction system until you hear it lock into place (Fig. 8). To use this feature, attach vacuum hose (optional accessory) to dust port, then connect opposite end of the vacuum hose to a shop vacuum cleaner. A vacuum hose adapter (optional accessory) is available for connecting this tool to a 1-1/4" or 1-1/2" vacuum hose (Fig. 8). The vacuum cleaner must be suitable for the material being drilled.

After the auxiliary handle is installed, make sure the accessory has been fully inserted into the chuck before setting the depth gauge. Set the depth gauge by compressing the telescopic guide toward the tool. When the desired length of the bit is exposed, press and slide the depth stop button against the guide housing and release the button (Fig. 9).
