CAUTION: Relieve hydraulic pressure before connection.

NOTE: When connecting hydraulic hoses, ensure that hose tag matches tractor SCV symbol.

Extend and Retract symbols are on SCV cover. Refer to tractor operator’s manual for description of tractor controls.

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

IMPORTANT: Improper hose connection can damage motor seals. Connect the case drain hose before any other hose. Improper use of tractor SCV’s can damage motor seals. Move tractor SCV lever to float (not neutral) position to shut off cart fan.
