NOTE
:
The cable should be reeled out onto a smooth, clean surface or payed out into
a drum. Exercise care to prevent kinking of the cable.
Reel in cable by using both the pendant and the pilot
payout controls and verify hoist stops when hook
reaches upper limit without excess tension on cable.
Verify that pilot's pay out switch overrides hoist oper­
ator's pendant control.
OPERATE HOIST
NOTE
:
It is important that the cable be reeled in with an even pull under a drag load of
10 to 20 lb (4.54 to 9.07 kg) so that it does not wrap loosely on the drum. A drag
load must be applied using a gloved hand or clean heavy cloth on the cable to
achieve tight, even layers on the drum.

Maintain hover until the load is inside the passenger cabin – unless
safety or operational conditions dictate otherwise.
NOTE
:
Certain combinations of weight and cable length may induce a noticeable
lateral oscillation. Should a lateral oscillation occur, raise or lower the load to
alleviate this condition.
