APPENDIX B. MANEUVERING POSITION

a. Placing Dolly Half in Maneuvering Position.

WARNING

DO NOT operate control valve levers to put front or rear dolly in maneuvering position

unless telescopic brace and front axle steering locking pin are installed. Telescopic

brace and front axle steering locking pin must ALWAYS be installed before lift

cylinders reach their vertical position. Failure to follow this warning may cause front

or rear dolly to overturn, resulting in serious injury or death to personnel.

CAUTION

Use extreme caution to ensure that near (left side) top beam vertical tube does not

contact control valve and fittings and cause damage when placing dolly half in

maneuvering position. Carefully follow all steps and monitor position of lift cylinders

and pivoting tray to guard against binding and interference.

NOTE

The maneuvering position is a three-wheel configuration. The dolly half's center of

gravity is shifted over the axle, the top beam is resting over the drawbar, and the axle

is level with the ground. In this position, the dolly half can be easily moved and

positioned where required.

Before proceeding, ensure that all stowed items such as rear drawbar, ladder, and

intradolly air hoses and cable have been removed; air bags must be deflated;

transportation lockouts have been secured to top beam vertical tubes with stowage

straps; and toolbox has been closed.

The following steps are performed at the front and/or rear dolly as required.

Procedure begins with bottom beam resting on ground with top and bottom beams

vertical and engines running at high idle.

(1)

Ensure that front axle steering locking pin (40) is installed to lock steering. Ensure that

telescopic braces are installed.

(2)

Pull down on positioning cylinders lever (71) to extend positioning cylinders (2) until

telescopic brace (49) reaches rest pin (50).

(3)

Quickly push up on positioning cylinders lever (71) to FLOAT position.
