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.
