Pipe safety valve
The pipe safety valve prevents the load from suddenly lowering dur-
ing lifting operations in the event a pipe or hose bursts.
A pipe safety valve (1) is located on the hydraulic port of the boom
cylinder and arm cylinder, respectively.
Additionally, a pipe safety valve can be mounted to the hydraulic
port of the dozer cylinder.
Machines that will be used for lifting operations must be equipped
with at least one pipe safety valve on the boom and arm, together
with an overload warning system (page 33) according to EN 474-5.
If the dozer is being used to increase the machine’s stability, an ad-
ditional pipe safety valve must be installed in accordance with
EN 474-1.
To acquire the proper equipment for your machine, please contact
your KUBOTA dealer.
The pipe safety valve is adjusted in the factory on the particular ma-
chine.
Manipulating the pipe safety valve will void the warranty.
The manipulation and repair of the pipe safety valves is prohibited. They may only be replaced by your KUBOTA
dealer as a kit.
Any manipulation can result in substantial personal in-
juries, even death, and is therefore strictly prohibited.
