Using Third Selective Control Valve (SCV) Outlet—If Equipped

CAUTION: Avoid injury! Escaping fluid under high pressure can penetrate the skin and cause serious injury. Avoid the hazard by relieving pressure before connecting hydraulic or other lines. Tighten all connections before applying pressure.

• Search for leaks with a piece of cardboard. Protect hands and body from high-pressure fluids.

• If an accident occurs, see a doctor immediately. Any fluid injected into the skin must be surgically removed within a few hours or gangrene may result. Doctors unfamiliar with this type of injury should reference a knowledgeable medical source. Such information is available from Deere & Company Medical Department in Moline, Illinois, U.S.A. In the United States and Canada only, this information may be obtained by calling 1-800-822-8262.

NOTE: Some continuous flow attachments can elevate tractor oil temperature. Make sure to refer to the OM of the attachment and supply the device the proper flow rate. In the event that the tractor hydraulic system overheats, the valve will disengage, and the light will remain lit. Operate the tractor for 10 minutes at mid engine speed to cool it down, identify the cause of the overheating, and resume work.

This machine model series can be equipped with an optional Third selective control valve (SCV) outlet kit to operate hydraulically driven implements from one set of outlets at the mid-mount position or the rear-mount position.

The machine-mounted hydraulic outlets are female quick couplers.

A - Activation Switch

B - Off

C - On

D - Enable

•Continuous Flow Enable Switch (A): This switch will supply continuous flow to a hydraulic device.

• Off (B): Place switch in this position to deactivate continuous flow from the third SCV outlet or depress the bottom of control switch (H).

• On (C): This position will activate continuous flow from the third SCV outlet after the key switch has been turned on. Turning the key switch off will deactivate the continuous flow circuit. When the key switch is turned on, the third SCV continuous flow circuit will not activate until after the operator presses and releases the switch in the momentary enable (D) position.

NOTE: The green light in the switch will illuminate if continuous flow is activated.

• Enable (D): This is a momentary position that will reactivate the third SCV continuous flow circuit. When the switch is depressed and released, it will return to the center on position.

Using Third Selective Control Valve (SCV) Outlet Control

The third (SCV) outlet may be operated in a momentary condition to operate attachments such as extending or retracting a hydraulic cylinder. The attachment will receive full hydraulic flow in direct response to the use of the control switch.

2. Depress the bottom of the third (SCV) control switch (H) to allow flow from the circuit out the lower outlet (G) and return to the machine through the upper outlet (F).

IMPORTANT: Avoid damage! To prevent contamination of female quick couplers, color-coded hose ends should be installed in the couplers when not being used.
