Working with the machine

CAUTION
Material with high dust generation (e.g. plaster-
board)
Damage to machine through dust penetration,
risk of injury
Do not work overhead!

When working on small or thin workpieces, always
use a stable base, or the CMS module (accessory).
When working, hold the electric power tool by the
handle and guide it along the desired cutting line.
For precise cuts and smooth running, use two
hands to guide the electric power tool.
Free saw guidance along a scribe mark
The triangular pointer on the splinterguard [4-1]
indicates the cutting line of the saw blade. This fa-
cilitates sawing along a scribe mark.
