Overview
To reduce the risk of serious injury or death to
yourself or others, read the Safety instructions
section found on the previous pages of this
manual before operating the machine.
Design and function
SB is a range of rig mounted hydraulic breakers
designed for all kinds of demolition works. No other
use is permitted.
SB has a solid body which means that the breaker
body is made in one piece. The accumulator is
integrated with the body.
The hydraulic breaker is operated from the driver's
cab of the carrier using the carrier's hydraulic
system. The breaker frequency is controlled by the
oil flow from the carrier.
Recommended working tools are listed in the
spare parts list.
