CAUTION: Escaping high-pressure fluid can penetrate the skin causing serious injury. Avoid the hazard by relieving pressure before disconnecting the system lines.

If an accident occurs, consult a doctor immediately. Any fluid that penetrates the skin must be surgically removed within a few hours or gangrene can result.

CAUTION: Help prevent personal injury. Before implements are attached, hydraulic hoses are connected, and to avoid unintentional implement movement, observe the following:

• Shut off the engine.

• Set selective control valve controls to neutral position and lock them.

IMPORTANT: Hydraulic hoses can fail due to physical damage, kinks, age, and exposure. Check hoses regularly.

Any dirt, dust, or other foreign material can damage hydraulic system. Thoroughly clean hydraulic hoses and SCVs before connecting an implement to the tractor.

IMPORTANT: Steam cleaning or using a high pressure washer in the area around the SCV connections and electronics may damage equipment. In the case of high-pressure washers with a pressure of more than 6895 kPa (69 bar) (1000 psi), a min. distance of 200 mm (8 in) to the connections has to be maintained.

NOTE: Hydraulic connections at front of tractor and/or under the right step (if equipped) are operated by the multi-function lever.

Connecting the hydraulic hoses

1. Engage the park lock and shut off the engine.

2. Lock out SCV controls:

   • Move the multi-function lever to neutral position and latch with the locking button or ring (A).
   • Bring the SCV control lever into the neutral position and lock with the locking button or lever (B).
   
   

3. Clean dust caps/plugs.

4. IMPORTANT: Be sure to connect hydraulic hoses of implements to couplers correctly. If hose connections are reversed, machine will not respond to system controls as expected.

   Assignment of couplers on front hitch

   Extend = Left port

   Retract = Right port

   Pull off caps/plugs to expose connections.

5. Push hoses firmly into connections.

Disconnecting hydraulic hoses

CAUTION: Avoid personal injury. Before implements are detached, hydraulic hoses are disconnected, and to avoid unintentional implement movement, observe the following:

• Lower implements to the ground.

• Set selective control valve controls to neutral position and lock them.

1. Engage park lock.

2. Lower implement to ground.

3. Move SCVs to float position for a few seconds while ignition is on or engine is running.

4. Lock out SCV controls:

   • Move the multi-function lever to neutral position and latch with the locking button or ring (A).
   • Bring the SCV control lever into the neutral position and lock with the locking button or lever (B).
   
   

5. IMPORTANT: Forcing or jerking SCV hoses when disconnecting can damage hose ends and SCV couplers. If hoses cannot be removed easily, relieve pressure in hydraulic system by putting the SCV in float position for a few seconds with engine running.

   Pull hoses in a straight line out of connections.

6. Turn dust covers down to cover connections.
