(18) Retract the holdown pin (8) by lifting up on overhead cylinder lever #1 for about 30 seconds.

WARNING

Due to the noise of the engine,

communication between the dismounted

crew member and the operator will be

strained. Ensure that a visible hand

signal is used and the meaning of such

hand signal is understood. Early

operation of the holddown cylinder

could result in the hands or fingers of

the crew member being severely injured

or severed. Take all necessary

precautions to avoid injury.

(19)

Place both tiedown chain turnbuckle eyes in the socket (9) of the holddown cylinder bracket

(10) located on the bridge seat (11).

(20)

Extend the holddown pin (8) by holding down on lever #1 until the tumbuckle eyes are

securely pinned in the holddown cylinder socket (9).

(21) Reduce engine RPM to idle. Disengage the power takeoff clutch and cycle the control levers

up and down to the launching and retrieving positions two or three times to relieve the

pressure in all hydraulic lines.

be transported.
