To adjust the mitre square, you must first loosen the wing screws. Then swivel the device sideways and set the desired measurement on the scale. Then you can tighten the wing screws again. To adjust the cutting depth, first release the clamping lever. Afterwards you either pull the saw away from the base plate to get a smaller cutting depth, or you push the saw to the base plate to get a larger cutting depth. A rip fence and cutting line guide are also possible.


You can saw through wood easily.


The device is protected against children due to the switch-on lock. The run-out brake, which reduces the after-running of the saw blade after it has been switched off, also ensures safe handling of the hand-held circular saw.

Before cleaning, you must remove the battery from the circular hand saw. You can clean dust and shavings either by blowing it out with compressed air or by removing it with a brush.
