•
Despite the safety system, blank firing must be prevented to reduce
damage to the fastening elements, the tool holder, and the tool!
NOTICE
As soon as the material breaks into single parts, the breaker must be switched
off immediately!
•
The standard breaker is not suitable for underwater work, because water
will penetrate the impact chamber of the breaker and cause dangerous
shock waves with each impact.
A conversion set for such work is available upon request.
•
Operate the breaker when the excavator is stable on an even and compact
surface.
WARNING
In case of contact with high-voltage lines, do NOT leave the cabin of the
carrier machine; move the machine until there is no longer contact and a safe
distance has been reached.

Gas support - nitrogen N
2
The
SB hydraulic breaker
is equipped with a
gas support system
.
It consists of a pressure chamber filled with
nitrogen (N
2
)
that is located on
the upper part of the breaker.
If a
decline in performance
of the breaker is noticed, the
nitrogen pressure
in the upper part
of the breaker must be checked and refilled (see table -
Nitrogen pressure guide values
):
