HYDRAULICS
The relief valve is typically located internally in the control valve. Do not adjust this relief valve above 2500
PSI (172 bar). The relief valve system is a simple spring tension design but small pieces of debris can stick
the valve partially open which weakens the feedwheel power. The relief as well as hydraulic oil, and screen
must be kept clean.

Control Valve
1. VALVE SEAT:
The springs pushes the relief valve ball against it, until pressure builds.
2. POPPIT VALVE:
This ball opens and closes to relieve excess pressure on hydraulic system.
3.
RELIEF SPRING:
This spring tensions the amount of pressure required to open the relief valve ball. This spring weakens
and must be checked and/or readjusted every month for best performance.
4.
ALLEN SET SCREW:
Turn clockwise using a 1/4” allen wrench to increase pressure, but do not surpass maximum of the
specifi ed PSI (bar). Previous valves require 7/32” allen wrench or a fl at head screw driver.
5. HEX HEAD PLUG:
Remove to access the relief valve.
