HYDRAULIC PRESSURE SETTINGS (595 ML CRL)
RELIEF VALVES
The Relief Valve portion of the control valves in your Barko Loader limit the flow of hydraulic oil, which relieves the
excess pressure in the hydraulic system, if for any reason pressure is built up above a predetermined, safe, maximum.
CAUTION
The relief valve pressure setting has been arrived at by our engineers after considerable
experience with and testing of this loader. The setting will provide maximum safety and
efficiency of operation. DO NOT ALTER THIS RELIEF SETTING! Relief settings increased
beyond this setting could be dangerous to life, limb and property.
Altering the settings on a new machine will void the warranty.
The following is a list of pressure settings used on your Barko Loader. Any questions should be directed to the factory.
