14. Recirculation Kit
15. Hydraulic Pressure Regulator
Allows the pressure of the hydraulic system to be increased or
decreased. Turn clockwise to increase the pressure and
counterclockwise to reduce it. In order to regulate the pressure
of the hydraulic system, the NORMAL or RETRACT key must be
activated.
The regulation mechanism has two configurations:
a) Limiting of pressure with pin, for low pressure hoses (up
to 155 bar).
b) Limiting of pressure without pin, for high pressure hoses
(up to 276 bar).
Regulate the hydraulic system so that the output pressure of the unit
never exceeds the pressure of work of the installed product hoses.
