2.16.5 Use of Multiway Valve
Shut off the engine.
Put the lifter in the lowering position.
Move the hydraulic output valve operation handle
forward and backward, in order to eliminate the
pressure in the hydraulic quick disconnect.
Remove the seal cover of the quick disconnects to
be used and clean the connectors.
Connect a hose with a male connector into the
female end of each quick disconnect on the valve.
Connect the other ends of these hoses to the oil inlet
and outlet of the double-acting oil cylinders on the
farm implement. The multi-way valve has four female connectors
(A1, B1, A2, and B2). A1 and B1 form the first group of the
hydraulic output loop and are controlled by control lever C.
A2 and B2 form the second group of the hydraulic output loop
and are controlled by control lever D.
IMPORTANT ISSUES:
1.
When a quick disconnect is not used, the connector seat should be covered with a seal cover to avoid dust.
2.
After the hydraulic output device is used, the operating handle should be set to the neutral position, otherwise
the hydraulic system may overheat.
