Use care when unreeling the hydraulic hoses from
the boom hose reel as the hose reel is under tension.
Do not release the hydraulic hoses and allow them
to rewind onto the reel as this will allow hoses to
swing freely until the tension on the reel is relieved.
When attaching tag lines to grapple, ensure they are
even, secure, and taut so that there will be no tension
on hydraulic hoses when connected.
Unclasp the hose reel tag lines from stowage link, and while maintaining the
preload on the hose reel, pull the hoses from hose reel on end of boom.
Then hook tag lines onto rings of grapple, remove caps on hose fittings and
cylinder fittings, and connect quick disconnect fittings to grapple cylinder
Position grapple by lifting, swinging, and telescoping the boom and by
hoisting the grapple.
To prevent bird caging of hoist cable, permit as little
slack in cable as possible when operating the
grapple. Correct any bird caging as soon as detected
to prevent having to rewind entire length of cable.
Raise and lower the grapple using the Boom LIFT/MAIN HOIST Control
