3 - Coupling position (E)
(OPEN HYDRAULIC CIRCUIT).
This position is used to obtain a continuous unidirectional
oil flow for the operation of equipment such as excavator,
demolition hammer, sweeper, etc. To hold the lever (1) in
coupling position (E), rotate the lever further to the left.
NOTE
The lever (1) remains in coupling position (E) only with pres-
q
surised hydraulic system.
When the lever (1) is in position (E), pressurised oil is deliv-
ered from the male coupling (3), with return to the female
coupling (4).
