Connect Cylinder Hoses—Rear SCV

CAUTION:

X9811
X9811-UN-23AUG88

Escaping fluid under pressure can penetrate the skin causing serious injury. Avoid the hazard by moving all rear SCV control levers and mid-mount joystick in all directions to relieve pressure before disconnecting 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.

    A - Coupler Covers

    Remove dust caps (if equipped) from hose ends.


  4. Open coupler covers (A).

  5. CAUTION: Hydraulic hoses can fail due to physical damage, kinks, age and exposure. Check hoses regularly. Replace damaged hoses.

    Making sure hose end and coupler are clean, push hose tip firmly into coupler. Pull on hose to make sure positive connection was made.

  6. CAUTION: Hoses that have been reversed when connecting pose a serious hazard. If SCV lever is pushed all the way forward to float, implement would drop suddenly, potentially causing serious injury or death. Never attempt to use float before you have performed the following verification step.

    To make sure hoses have been connected to correct receptacle, pull SCV lever I slightly back of center. This should raise implement. If implement lowers instead of rising, hoses are reversed and need to be connected correctly.

Always use SCV extend ports for lift functions for best performance. Deluxe SCV sections (with flow control and selectable detents) perform better than standard SCV sections.
