Hydraulic Hose Burst Check Valve warning page
(1) OK buttonThis machine is equipped with a hose burst check valve system. This system is for countries with specific regulation requirements that the implement linkage does not fall when there is a rupture in a hydraulic hose. A warning page appears. The warning appears providing awareness to operators because the hydraulic hose burst check valve is being bypassed by the ride control system hydraulics. The aforementioned warning informs operators that whenever the ride control system is active, the hydraulic hose burst check valve is being bypassed. When the hydraulic hose burst check valve is being bypassed, the regulation will not be satisfied. Also, the implement linkage will fail should a hydraulic hose rupture. When the machine is keyed on and the Hydraulic Hose Burst Check Valve is installed, a warning page will appear with the following message:
