Removal of Hydraulically Powered Attachments
After use, the quick couples and hydraulic uid will be very hot. Wear gloves when dis-
connecting the auxiliary hydraulic lines.
To remove a hydraulically powered attachment;
1. Lower the attachment to the ground and shut off the engine.
2. Move the hydraulic control levers forward or backward to release any stored
hydraulic pressure.
3. Some of the female couplings will have a lock button preventing accidental
disconnection. To release this type of quick connect, rotate the collar on the
female quick connect (Item 1, Figure 3–41) to align the notch on the collar with the
lock button (Item 2, Figure 3–41).
4. Slide the collar backwards on the female quick connect (Item 4, Figure 3–41) until
it stops against the lock button (Item 3, Figure 3–41). The male connector will be
released. Move the attachment hose away from the bulkhead tting.
5. If the female connector does not have the lock pin type collar, just slide the collar
backwards until the male connector is released.

6. Repeat this procedure on the other hydraulic line.
7. Cover the hose connections with the dust caps (Item 5, Figure 3–41) and store the
hydraulic hoses to prevent damage.
8. Follow the instructions in “Removal of Attachment” earlier in this section to
complete the attachment removal.
