CAUTION: Relieve hydraulic pressure before connection.

NOTE: When connecting hydraulic hoses, ensure that hose tag matches tractor selective control valve (SCV) symbol.

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

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 the blower return hoses to a tractor “extend” SCV.

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