Control Valve Label

A - Dual Selective Control Valve (SCV) Lever

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

The label installed on the machine next to the dual selective control valve (SCV) lever shows the different lever positions.

Lever positions numbered 1—4 on the label match hydraulic line couplers numbered 1—4 on the label installed on the machine near the couplers. Moving the lever to position 1 will supply fluid to coupler 1 and return fluid through coupler 2 and so forth.

Move the lever to the full right or “regen” position for faster loader bucket dumping.

Move the lever to the full forward or “float” position to remove pressure in both lines 3 and 4 and allow fluid to flow back and forth between the lines. The lever may be left in the “float” position.

B - 0 Position

C - 1 Position

D - 2 Position

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

Selective control valve (SCV) lever lock does not lock out switch-operated third-function hydraulics, which are active anytime the key is ON.

Selective control valve (SCV) lever lock (A) allows the operator to control the type of dual SCV lever movement needed for a particular operation or situation. Operation of the SCV lever lock is indicated on SCV lever lock label.

• To prohibit movement of SCV lever in all directions, move SCV lever lock in to the 0 position (B). Operation of the SCV is totally locked.

• To prohibit engagement of the REGEN (regeneration) function of the SCV, pull lever lock to the middle or 1 position (C). This will lock out the loader bucket function. REGEN can cannot be used for hydraulic motors, and it will always cause a cylinder to extend regardless of connections. REGEN is intended to increase bucket dump speed and eliminate cavitation in bucket cylinders.

• To allow movement of SCV lever in all directions, move SCV lever lock to the 2 position (D). Operation of the SCV is totally unlocked.

• To prohibit movement of dual SCV lever in all directions, make sure SCV lever (B) is in center position, and press the SCV lever lock (A) to the in position (C). Operation of the dual SCV is totally locked.

• To allow movement of dual SCV lever in all directions, move SCV lever lock to the center position (D). Operation of the dual SCV is totally unlocked.

To prohibit engagement of the REGEN (regeneration) function of the SCV, pull lever lock to the full out position (E). This will lock out the loader bucket function. REGEN cannot be used for hydraulic motors, and it will always cause a cylinder to extend regardless of connections. REGEN is intended to increase bucket dump speed and eliminate cavitation in bucket cylinders.

NOTE: After extended use, the dual SCV lever may require cable adjustment to lock out.
