9 Practical Tips
Do not drill into hidden electrical
lines or gas and water pipes.
Check the area to be worked with a
metal detector, for example, before
starting.
For metal, use only flawless, sharpened drills; for
stone and concrete, only masonry drills with hard
metal inserts.
Always adapt the speed to the material to be worked
and the diameter of the drill. For precision working
with metal and wood, place the machine in a drill
stand (accessory).
The most effective method for chiselling is to break
out only small pieces of material.
When chiselling, work only with protective glasses
and the auxiliary handle 12. Check before starting
