Operate Mid SCV Multi-Function Control Lever—If Equipped

CAUTION: Overheated hydraulic oil can cause personal injury and component malfunctions. To prevent hydraulic oil from overheating, DO NOT hold multi-function control lever in operating position for an extended period of time.

A - Multi-Function Control Lever

B - Front—Boom Lower

C - Back—Boom Raise

H - Fast Speed

I - Detented “Float” Position

J - Third-Function Operations

Multi-function lever controls any hydraulically driven device connected to mid selective control valve (SCV), most commonly a loader.

NOTE: Multi-function lever and loader operation depend on hose to coupler connection. See “Connect Cylinder Hoses to Mid SCV—If Equipped” in this section.

1. A single function operates when control lever (A) is moved straight away from center, in one of four primary directions (front, back, left, or right).

   • Front—Boom Lower (B)
     • Full-front (I) is a detented position used for “float” operations.
   • Back—Boom Raise (C)
   • Left—Bucket Rollback (Curl) (D)
   • Right—Bucket Tilt (Dump) (E)
   
   

2. Two functions operate simultaneously when lever is moved at 45° angles from primary directions, into a two-function zone (F). Two-function zones are: Boom Lower/Bucket Dump, Bucket Dump/Boom Raise, Boom Raise/Bucket Curl, Bucket Curl/Boom Lower.

3. When lever is released to spring-centered neutral position, mid-mount valve holds boom and bucket in position.

4. Cylinder operating speed depends on how far from center the control lever is moved. When lever is first moved from center, hydraulic functions operate slowly (G), then move progressively faster as lever is moved further away from center, out to fast speed operating position (H).

5. Third functions controlled by switch (J) can be operated simultaneously with any single and two function operations.

“Float”: Push lever full forward into detent when “float” is desired. “Float” position (I) allows loader boom to move up and down freely while traveling over rough ground. Manually return lever to neutral when “float” is no longer needed.

Transport Lock

Locked

LV12595-UN-21APR05

Unlocked

A - Transport Lock

CAUTION: To prevent loader movement, engage control lever transport lock (A) before dismounting tractor. Control lever must be in center (neutral) position for lock to engage.

Transport lock does not lock out switch operated third-function hydraulics, which are active anytime the key is ON.

• Push IN to lock.
• Pull OUT to unlock.

NOTE: Lock is engaged when dashed line is in against body and lever does not move.

Third-Function (Electrohydraulic)

LV9662-UN-20AUG04

A - Mid SCV Third-Function Switch

Switch (A) controls third-function hydraulics connected to three-function mid-mount valve. Third-function hydraulics are active anytime the key is ON.

• Top half pressed: Attachment retract/raise (grapple open).
• Bottom half pressed: Attachment extend/lower (grapple close).

NOTE: Front switch is not operational in this application.

Manually Operating Third-Function (Electro-Hydraulic) Valve Section

LV14617-UN-11AUG11

A - Access Hole (Extend)

B - Access Hole (Retract)

Third-function (grapple) valve section can be manually operated if an electrical malfunction occurs.

Insert a small diameter punch through access hole (A or B) and push spool to either extend or retract cylinders as needed to release load.
