Observe the safety instructions and warnings in this documentation and on the product.
5.1.1 Fitting the dust removal module
Before fitting the module, check that the attachment points and the electrical interfaces on the rotary
hammer drill and dust removal module are free of dust and that the parts fit or move freely and easily.

3. Remove the depth gauge from the side handle.
4. Push the dust removal module onto the tool from the front until it engages.

5.2 Types of work
5.2.1 Setting the length (stroke)
WARNING
Risk of injury The telescopic section will jump out when the stroke preselection button is pressed.
▶ Hold the rotary hammer with the dust removal module so that the telescopic section cannot injure you
when it jumps out.
The default stroke setting is for a drill bit length of 170 mm. The stroke has to be adjusted if shorter
drill bits are used.
1. Press the stroke length limiter and keep it pressed.
2. With the drill bit fitted, press the rotary hammer drill against the working surface until the tip of the drill
bit comes into contact with the surface.
3. Release the stroke length limiter.
5.2.2 Setting drilling depth (depth gauge)
If drilling depth has to be exact, drill test holes to establish the correct depth.
1. Press the depth gauge and keep it pressed in.
2. Move the ring to the desired drilling depth.
3. Release the depth gauge.
5.2.3 Cleaning the TE-DRS-T1 filter
Clean the filter after drilling 5 holes (16 mm x 50 mm) (1/2 in x 3 in).
▶ When suction power diminishes, slide the cleaning mechanism 5 times forward and back until it audibly
clicks on each slide.
5.2.4 Emptying the dust box
Dust can escape if the filter is full, so it has to be emptied regularly. Wear respiratory protection when
doing this.
