Clamp shaft with pliers and insert into the mount to the

Never overload the tool by pressing too hard. Always
remember that power is provided by the rotational
speed and not the contact pressure.
Working with the tool:
Switch on the tool and hold like a pen with a gentle
grip. Rest the lower half of your arm on the table or
against your body. After some practice, we recommend
that you work with templates (available in shops).
Simply adhere these to the rear of the glass with
adhesive tape. Always make the outline first. Use the
diamond abrasive pencils to do this. Then create matt
surfaces with the silicon-carbide pencils.
W ar ning:
While working dangerous dust can be emitted!
Never work without wearing googles and dust mask.
Always remember:
Practice makes perfect. At the beginning, use simple
types of glass (panes or cylindrical glass). Use dark
materials underneath to give a better contrast.
