1. Park machine safely. (See Parking Safely in the SAFETY Section.)
2. Leave engine off and move key switch to the RUN position.
MX23740, MX13918
3. Turn the third SCV switch (A) to the ON position.
4. Switch the third SCV continuous flow switch (B) to the A position and connect the implement to the right coupler (C) to relieve tractor hydraulic hose pressure.
5. Switch the third SCV continuous flow switch (B) to the B position and connect the implement to the left coupler (D) to relieve tractor hydraulic hose pressure.
6. Turn key switch to OFF position.
7. Disconnect implement from couplers.
Connecting Hydraulic Hoses
c CAUTION: Avoid injury! Do not attempt to connect hoses to machine SCV couplers until all hydraulic system pressure has been relieved.
An operator must continuously be aware of all bystanders and other equipment at the worksite, implements may move during this procedure.
1. Relieve hydraulic hose pressure before connecting hydraulic hoses.
MX13918, MX13918
2. Pull back on outer knurled ring (E) and push couplers together with a firm continuous motion until couplers lock into place.
Removing Hydraulic Hoses
1. Relieve hydraulic hose pressure before removing hydraulic hoses.
2. Push hydraulic hose in while pulling back on outer knurled ring (A). The coupler will unlock and hydraulic hose can be removed.
