Masonry slitting apparatus

Masonry-slitting apparatus comprising a housing (1) having a first end region a second end region and side regions extending between the end regions, a first handle (10) located in said first end region and a second handle (9) located in said second end region, a drive unit (2) mounted in said housing (1), an electric switch (5) for actuating said drive unit (2), a slitting member (4) connected to said drive unit for rotating at least one disk (25) for effecting a slit in a base material (U), said housing (1) being pivotally mounted on a trolley (3) about a rotary bearing (6) disposed in the first end region of said housing (1) and being pivotally displaceable against the biasing force of a spring element (7), said at least one disk (25) forming a disk plane extending between and transversely of said end regions and said housing being pivotally displaceable parallel to said disk plane, an arresting element (8) located in the second end region of said housing for limiting pivotal movement between said housing (1) and said trolley (3), said arresting element (8) being actuated by a locking switch (11) located in said second handle (9), each said handle (9, 10) having a substantially cylindrically-shaped gripping surface (12, 13) extending substantially perpendicularly to said disk plane and parallel to one another, and said electric switch (5) being located in said first handle.
