•  Check that it is seated securely by pulling the saw blade. A loose saw blade can fall out and lead to injuries. For particular jobs, the saw blade (1) can also be flipped 180° (teeth point upwards) and refitted.

Removing the saw blade

•  Let the saw blade cool down before removing it. There is a risk of injury when touching the hot saw blade. Press the SDS lever (4) forward and pull out the saw blade (1). Release the SDS lever (4).

Dust/Chip Extraction

Dust from materials such as lead-containing coatings, some wood types, minerals, and metal can be harmful to one’s health. Touching or breathing in the dust can cause allergic reactions and/or lead to respiratory infections of the user or bystanders.
Certain dust, such as oak or beech dust, is considered carcinogenic, especially in connection with wood-treatment additives (chromate, wood preservative). Materials containing asbestos may only be worked by specialists.
–Provide for good ventilation of the working place.
– It is recommended to wear a P2 filter-class respirator.
Observe the relevant regulations in your country for the materials to be worked.

• Avoid dust accumulation at the workplace. Dust can easily ignite.

Operation

• Products that are only sold in AUS and NZ: Use a residual current device (RCD) with a nominal residual current of 30 mA or less.

Starting Operation

•  Pay attention to the mains voltage. The voltage of the power source must match the voltage specified on the rating plate of the power tool. Power tools marked with 230 V can also be operated with 220 V.

Worklight
The work light (9) lights up when connected to the mains power and improves visibility in the immediate work area.

To switch off the power tool, release the on/off switch (7). Note: For safety reasons, the on/off switch (7) cannot be locked; it must remain pressed during the entire operation.
Controlling the stroke rate
You can variably adjust the stroke rate of the power tool when it is on by pressing in the on/off switch (7) to varying extents.
Applying light pressure to the on/off switch (7) results in a low stroke rate. Applying increasing pressure to the switch increases the stroke rate.
The required stroke rate is dependent on the material and the work conditions and can be determined using practice tests.
It is recommended that you reduce the stroke rate when placing the saw blade on the workpiece and when sawing plastic and aluminum.
During prolonged periods of use at a low stroke rate, the power tool may heat up significantly. Remove the saw blade and let the power tool run at the maximum stroke rate for around three minutes to cool down.

Working Advice

•  Pull the plug out of the socket before carrying out any work on the power tool.
•  Switch the power tool off immediately if the saw blade becomes blocked.

Tips

•  When sawing lightweight materials, take into account the statutory provisions and recommendations of the material manufacturers.

Before sawing into the wood, chipboard, building materials, etc., check for any foreign objects such as nails, screws, etc. and use a suitable saw blade.
Switch on the power tool and guide it towards the workpiece you wish to work on. Place the base plate (2) on the surface of the workpiece and saw through the material applying even pressure and feed. Switch the power tool off once you have finished your work.
Switch the power tool off immediately if the saw blade jams. Widen the sawing gap slightly with a suitable tool and pull the power tool out.

Swiveling and removable base plate (see figures B−C)

Thanks to its mobility, the base plate (2) adopt the required angle position of the surface.
Depending on the application and the saw blade being used, the base plate (2) can be moved continuously in the length direction to different
settings.
Loosen the screws (12) with the hex key (8) and slide the base plate (2) into the desired position. Re-tighten the screws and check whether the base plate is fixed in place.

Plunge cutting (see figures D–E)

• Plunge cuts may only be applied to soft materials, such as wood, gypsum board, etc. Do not plunge cut metal materials.

For plunge cutting, use only short saw blades.
Place the power tool so that the edge of the base plate (2) rests on the workpiece, without the saw blade (1) touching the workpiece, and switch it on. When using power tools with stroke rate control, select the maximum stroke rate.
Press the power tool firmly against the workpiece and allow the saw blade to plunge slowly into the workpiece.
As soon as the base plate (2) rests fully on the workpiece, continue sawing along the required cutting line.

For particular jobs, the saw blade (1) can also be fitted after being turned 180° in order to operate the power tool the other way around.

Flush sawing (see figure F)
Protruding components such as water pipes, for example, can be cut directly at the wall using elastic bi-metal saw blades.

•  Ensure that the saw blade is always longer than the diameter of the workpiece. There is a risk of kickback.

Place the saw blade directly against the wall and bend it slightly by applying lateral pressure to the power tool until the base plate is flush with the wall. Switch on the power tool and saw through the workpiece applying consistent lateral pressure.

Utility hook (see figure G)
Your power tool is equipped with a utility hook (5) for hanging it, e. g., from a ladder. Simply fold out the utility hook to the required position.

•  When the power tool is hung up, take care that the saw blade is protected from accidental contact. saw blade is protected from accidental contact. This poses a risk of injury.

Fold the utility hook (5) in again when you want to begin work with the power tool.

Coolant/lubricant
