ikan JIB-01C - Manual (Page 6)

The JIB-01C has a two stage telescoping arm that can
extend and contract depending on the desired length.
The rear portion of the Jib also telescopes providing
quick counterbalance adjustments. The longer the arm
the more extended the rear counterweight tail will need
to extend.
Telescoping
Arm Adjustments:
To begin add the supplied weight to the tail section. To do
this you will need to attach the Tail Threaded
Counterweight Bolt securely. Next collect the supplied
weight (5.5lbs) the carabineer and washer for Weight bag,
and place on the bolt and secure with the Counterweight
Retainer Nut.The Jib will start a little tail heavy, but as you
extend the Jib it will balance out.
Decide how long you want to extend the Jib, then start by
extending the first stage.
Extend the Jib at the first set of twist locks (the larger set closer to the
base of tripod) Loosen the twist locks and pull out the camera platform
to desired length and fully tighten the twist locks. Please note that
there are bubble levels in two places to balance the camera platform.
One under the plate and another at the front of the baseplate carrier
platform. You may need to make small adjustments to balance the
baseplate carrier before you mount your camera.
