◆
Never use the hydraulic breaker to move
debris.
Breaking under water
Hydraulic breakers can be used for operating
under water.
bar
1.5-2
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
1
⁄4
in. hydraulic hose with JIC connection. Contact
your nearest authorised workshop for further
instructions.
Heavy duty operation
The hydraulic breakers SB 302 Tunnel and SB 452
Tunnel are specially suited for heavy duty
operations such as scaling in tunnelling and
underground applications. The Tunnel breakers
are equipped with water nozzles (A).
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 SB 52 and SB 102, 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.
Special applications
NOTICE Always consult the Customer Center /
Dealer in your area in case of special applications-
tunnelling, high thermal load and underwater
application.
You can contact your nearest authorised workshop
for further instructions.
Maintenance
It is essential that regular maintenance is
performed to maintain the breakers maximum
efficiency.
Equipment that is insufficiently maintained can be
dangerous for both the operator and persons near
the breaker. Make sure that regular maintenance
routines with lubrication are followed to keep the
equipment safe and efficient.
