Cutting mineral materials
Cutting mineral materials such as concrete creates a lot of fine dust.
Recommendation: Use the water connection of the power tool and cut-off wheels suitable for wet cutting
when cutting mineral materials.
When cutting with water supply, the dust is reduced, visibility is improved and the cut-off wheel service life
is increased by the cooling effect of the water.
Water connection for wet cutting: Î Chap. 5.7, page 20
Small pieces of mineral materials may be ejected from the cutting groove by the quick rotation of the
cut-off wheel.
x Rotate the wheel guard down as far as possible so the cut particles are ejected away from the user.
x Mark the cutting line and grind a groove of approx. 5 mm [approx. 3/16"] along the entire line at half
throttle that will guide the power tool precisely for the subsequent cutting process.
x Perform the cutting process with even movements back and forth.
x When fitting stone plates, application of a flat groove is sufficient (avoiding unnecessary dust formation),
to then cleanly strike off the protruding piece on a flat support.
