Adjustment of 3-way valve
The MANIFOLD valve can be adjusted if it is too tight to operate - or if it
is too loose (=liquid leakage). Correct setting is when the valve can be
operated smoothly by one hand. Use a suitable tool and adjust the
toothed ring inside the valve as shown on the drawing.
Retighten the frame
The frame are two sections bolted together. Also the drawbar is bolted to the frame. These bolts need to be tightened
correctly. Regularly check if bolts are tightened to the specified torque below.
