5. Description
5.1 Field of application
For breaking concrete and asphalt as well as rubble-laden ground, for
demolishing concrete, masonry and similar 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.
Always use the proper pin driving tool with the machine when ramming
posts or ground 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.
5.2 Functional description
On activation of the switch lever (1), and electric motor (2) drives the
crank mechanism (3) through a transmission (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 then strikes the tool directly (without any
intermediate piston).
