CONTROL ELEMENT (THREE CONTROL LEVERS)
Distribution of functions, according to control levers, is described in the following.
CONTROL OF HYDRAULICS THROUGH QUICK COUPLING (DOUBLE)
Control lever E
Control lever redirects oil from pressure circuit through two-way functioning 6/4-directional control valve
(version A) directly to quick coupling, to control implement with two-way functioning hydraulic cylinder.
As standard, quick couplings are already fitted with hydraulic top connection shaft or crossbar – top link,
position of which can be changed by the user.
Operation:
When you move the control lever for operation of control valve into one of the positions (1 or 2),
the piston in the valve moves in a way that oil from the pressure line flows only through one
connection and from return through other connection and vice versa, if you shift the control lever
in other direction.
When you release it, the lever on the control element automatically returns back to neutral,
regardless of previous position.
As the control valve also functions as blocking device (DETENT), you can also move the lever to
position 3. When you release it, the lever remains fixed in position 3. Therefore, you must always
manually move it to position 0, if you want to stop oil supply.
CONTROL OF HYDRAULICS THROUGH QUICK COUPLING (DOUBLE)
Control levers F and G
Control lever redirects oil from pressure circuit through two-way functioning 6/3-directional control valve
through hydraulic output or quick coupling, to control implement external hydraulic implements with
two-way functioning hydraulic cylinder.
Operation:
Operation is the same as with control lever E, when levers, regardless of position (1 or 2), always return
to neutral position, when released. The difference is that the valves do not have a blocking device
(DETENT).
