For breaking concrete and asphalt as well as rubble-laden ground, for demolishing concrete, masonry and sim-
ilar building materials (undisturbed and frozen ground) etc., for ripping up roads and concrete, asphalt, tar as
well as wood-block and stone paving, for cutting off clay, loam, turf and salts, for breaking compacted or
tamped ground, for ramming in posts and earth rods.

Damage will occur to the percussion system if posts and/or rods are directly inserted into the
toolholder. This will eliminate any responsibility for warranty claims and prevent unnecessary
customer complaints.

Functional description
On activation of the switch lever (1), and electric motor (2) drives the crank mechanism (3) through a transmis-
sion (4).
The rotary motion of the crankshaft journal is converted by means of a con-rod (5)and a guide piston (6) into a
linear motion and transmitted through an air cushion ("pneumatic spring") to the percussion piston (7).
The percussion piston (7) then strikes the tool directly (without any intermediate piston).
A built-in electronic control (8) ensures a low starting current and constant speed off the drive motor when idling
and under load.
