Extend and Retract symbols are on tractor selective control valve (SCV) cover.

Refer to tractor operator's manual for specific hydraulic operational details.

CAUTION: Avoid hydraulic hose failure due to physical damage, kinks, age, and exposure. Inspect hoses regularly. Replace damaged hoses.

IMPORTANT: Avoid motor seal damage. Connect the case drain hose before any other hose. Connect return hoses to a tractor “extend” SCV.

Avoid motor seal damage. Move tractor SCV lever to float (not neutral) position to shut off vacuum.

NOTE: Port locations for pressure, return, and load-sense vary by tractor model. (See your tractor manual.) Power-beyond hydraulic flow is active when the tractor engine is running.
