Abstract
A masonry-slitting apparatus has a housing (1) containing a drive unit (2) for a slitting member (4), and a trolley (3) on which the housing (1) is pivotally mounted about a rotary bearing (6) located in a first end region of the housing. The housing (1) has a first handle (10) in the first end region and a second handle (9) in a second end region at the opposite end from the first end region. Each handle (9, 10) has a substantially cylindrically shaped gripping surface (12, 13) extending parallel to one another and disposed at right angles to a disk plane of the slitting member (4). An electric switch (5) is located in the gripping surface (13) of the first handle (10) and a locking switch (11), actuating an arresting element (8), is located in the gripping surface (12) of the second handle (9).
