WARNING
Risk of injury! Risk of kickback.
▶ Apply the appropriate safety measures at the rear of the workpiece when plunge sawing. Use only
suitable saw blades (length as short as possible).
Use the plunge cutting technique only on soft materials and only with short saw blades. The product
can be used in one of two plunge cutting positions: in the normal position or in the reversed position.
1. Bring the forward edge of the AVR contact shoe into contact with the workpiece.
2. Disengage the transport lock.
3. Press the control switch.
4. Press the forward edge of the contact shoe against the workpiece and begin the plunge action by slowly
increasing the angle of attack.
To prevent stalling, it is important that the product is running before the saw blade is brought into
contact with the surface.
5. Once the saw blade has penetrated right through the material, bring the product into the normal working
position (AVR contact shoe flush with the workpiece) and then continue sawing along the cutting line.
5.10 Changing the AVR contact shoe
The AVR contact shoe can be changed when required.
1. Engage the transport lock.
2. Remove the saw blade.
3. Pull the rectangular plastic pin forward.
It is located between the two AVR contact shoe guide pins.
4. Pull the AVR contact shoe out.
5. Press the rectangular plastic pin back into the original position.
6. Lightly grease the AVR contact shoe and insert it fully into the guide.
7. Check that the contact shoe has engaged.
