Adjustment
Adjustments should be made with the oil at normal operating
temperature of 80 to 130 degrees F.
Relief valve adjustment screw (back side of this block)
The adjustment for the relief valve is located as shown above. Turning the
adjustment screw clockwise (in) raises the relief pressure: turning it
counterclockwise lowers the relief pressure. The screw takes a 5/32" Allen
wrench: the locknut for the screw a 9/16" wrench.
The relief valve setting can be determined by operating the unit with no
equipment connected to the quick disconnects, the bypass closed, and
observing the pressure reading on the panel gage.
DO NOT OPERATE THE UNIT WITH EQUIPMENT
DISCONNECTED FOR OVER FIVE MINUTES. THINGS WILL GET
VERY HOT.
It is NOT recommended to exceed the factory setting of 2500 psi. Doing
so will shorten the life of the pump, perhaps dramatically.
