5.1 Preparations at the workplace
WARNING
Risk of injury by inadvertent starting!
▶ Before inserting the battery, make sure that the product is switched off.
▶ Remove the battery before making any adjustments to the power tool or before changing accessories.
Observe the safety instructions and warnings in this documentation and on the product.
5.2 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.
1. Set the forward / reverse selector switch on the rotary hammer drill to the middle position.
2. Remove the depth gauge from the side handle.
3. Position the dust removal module on the guides and from the front, push it on to the power tool until it
engages.
4. After fitting, check that the dust removal module is secure.
5.3 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. Stroke has to be adjusted if shorter drill
bits are used.
1. Press and hold down the stroke preset button.
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 preset button.
5.4 Setting drilling depth (depth gauge)
If drilling depth has to be exact, drill test holes to establish the correct depth.
1. Press and hold down the button of the depth gauge.
2. Move the ring to the desired drilling depth.
3. Release the button of the depth gauge.
5.5 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.
1. Hold the power tool horizontal and allow it to run for a short time.
▶ This ensures that residual dust deposits in the dust removal module are drawn into the dust box.
2. Press and hold down the release button of the dust container.
3. Pull the dust box down and clear of the dust removal module.
4. Empty the dust box.
5. Push the empty dust box back into the dust removal module from below until it engages.
