16. Unplug and connect the hydraulic hoses going from

the hydraulic cylinders, brakes and engine

compartment to the cab. All of the hoses may be

accessed either above (6) or below (7) the frame.

the hydraulic hoses between the cab, hydraulic valve

plate and the engine compartment.

negative battery cables (9 and 10) to both batteries.

Connect the lower negative battery cable (9) to the

negative (-) terminal on the lower battery (11). Swing

the upper battery box (12) in and make sure that the

lip (13) on the upper battery box slides below the

knob (14). Secure in place with the knob.

19. Carefully examine all cab components, fasteners,

etc., one last time before engine start-up. Rectify any

faulty conditions.

20. Start the engine and check the operation of all controls.

Check for hydraulic fluid leaks. Check the hydraulic

fluid level in the tank and add fluid as required.

IMPORTANT: When the engine is initially started, run it

briefly at low idle and check the vehicle for any visual

sign of fluid leakage. STOP the engine immediately if

any leakage is noted, and make any necessary repairs

before continuing.
