CAUTION
Wear protective gloves. The cutting edges of the saw
blade teeth are sharp. The cutting edges may present a
risk of injury.
CAUTION
Wear protective glasses and a dust mask. The sawing
operation swirls up dust and wood chips into the air. The
dust and wood chips may be harmful to the eyes and
respiratory system.
CAUTION
Wear ear protectors. The power tool and the sawing
operation generate noise. Exposure to noise can cause
loss of hearing.

blade is securely attached.
6.2 Adjusting the cutting depth 4
NOTE

3 preset angles are possible: 22.5º, 45º and 56º.
1. Disconnect the supply cord plug from the power
outlet.
2. Release the cutting angle adjustment clamping
lever.
3. Pivot the base plate to the 0° position.
4. Set the preset angle indicator to the desired angle.
5. Pivot the base plate as far as it will go.
6. Tighten the cutting angle adjustment clamping lever.
6.3.2 Setting the bevel cutting angle without
presetting
1. Disconnect the supply cord plug from the power
