♦
The hydraulic breaker or the working tool is not to
be used as a lifting device. When lifting heavy
components use the hook on the carrier arm.
♦
Never use the hydraulic breaker as a sledge
hammer to demolish material.
♦
Never use the hydraulic breaker to move debris.
Breaking under water
Hydraulic breakers can be used for operating under
water.
NOTICE When operating under water the hydraulic
breaker must be fed with compressed air to keep the
area between the piston and the inserted tool free
from water. If the area between the piston and the
inserted tool gets filled with water, it may penetrate
into the hydraulic oil system when the hydraulic
breaker is started.
The air pressure must be 1.5-2 bar at the air inlet on
the breaker and the air consumption can be found
in "Technical data". Suitable air hose is a

in.
hydraulic hose with JIC connection. Contact your
nearest authorised workshop for further instructions.
Heavy duty operation
The hydraulic breakers SB302 SC and SB452 SC
are specially suited for heavy duty operations such
as scaling in tunnelling and underground applications.
The SC breakers are equipped with water nozzles
(A).
Use a permanent water flushing and air supply as
standard to minimize wear and enable dust binding
during operation. See "Hoses and connections" for
information about connecting utilities.
Other breakers in the SB series, with the exception
of SB52 and SB102, can be retrofitted with water
nozzles. More information about water nozzles can
be found in the Spare parts list.
Special attention should be taken to ensure proper
lubrication and maintenance during heavy duty
operation. The use of a permanent lubrication system
or the ContiLube™ II micro is recommended.
