Relieve pressure before connecting attach-
ment hoses
Machines with auxiliary hydraulic ports are built with a
Connect-Under-Pressure (CUP) valve for the auxiliary
hydraulic quick disconnects. Follow this procedure to
relieve the pressure prior to connecting the hydraulic
hoses from the attachment:
1. Using the palm of your hand push the 1/2 inch female
quick disconnect coupling toward CUP valve. When
done properly, the coupling will move about
10.0 mm
(
0.4 in
), relieving the stored pressure.
2. Perform the same action for the 1/2 inch male quick
disconnect coupling, relieving the stored pressure.
