KUBOTA pipe safety valve

The pipe safety valve prevents the load from suddenly lowering
during lifting operation in case a pipe or hose bursts.
A pipe safety valve is located on the hydraulic port of the boom
cylinder (2) and arm cylinder (1), respectively.
Additionally, a pipe safety valve can be mounted to the hydraulic
port of the dozer cylinder (3).
Excavators that will be used in the lifting operation, must be
equipped with at least a pipe safety valve on the boom and arm,
together with an overload warning function according to
EN 474-5.
An additional pipe safety valve in accordance with EN 474-1
must be installed before using the dozer for lifting operation
support.
To equip the excavator for the lifting operation, contact your
KUBOTA specialist dealer.
The pipe safety valve is adjusted in the factory on the particular
excavator.
Manipulating the pipe safety valve will void the warranty.
Any manipulation can result in substantial personal injuries, even death, and is therefore strictly
forbidden.
The manipulation and repair of the pipe safety valves is forbidden. They may only be replaced by your
KUBOTA dealer as a kit.

Note on the use

•
Check the pipe safety valve lead seal before using the excavator. Do not carry out any excavating work if
the lead seal is missing and/or the pipe safety valve is damaged.
•
It is not allowed to swing the boom during lifting operation.
