2.3 LIFTING THE BOOM
Position the boom upwards in your preferred
angle and secure it by fixing both hexagon bolts
in the boom cylinder with the Hex Key.
2.4 LADDERS
The ladders can be positioned
downwards by prying them up a little,
turning them to the side and folding to
the side of the carrier.
2.5 BASE PLATE ATTACHMENT
Optionaly the counterweight
baseplate can be positioned
on the main body for a realistic
configuration.
To connect the baseplate to the crane,
use pins from bag 1 with the tools.

2.6 PLACEMENT RAILING
Place the railings on the uperstructure
and counterweight baseplate.
2.8 COUNTERWEIGHTS
Place the counterweights
on the baseplate.
2.7 CABIN POSITION
Angle the cabin upwards and pull out the side step
with the tools.
2.9 WIND DOWN THE HOOK
Use the winch key to wind down the hook. Push in to
unwind the winch to keep tension on the rope to prevent
the wire from jumping off the sheaves. This can be done
manually or by hanging the hook weight on the hook.

2.10 EXTENDING THE BOOM
Now carefully pull out the telescopic boom while
maintaining tension on the hook ropes.
Start with the first boom section, this boom
allows for 100% extension, but also has the
45% and 90% extension option build into the
telescopic boom sections. This will result in the
boom section securing themselves in the 45%
position first.
You can use the winch key to
push the trigger inwards so
you can proceed extending the
boom to the fully extended
position.
2.10-1 RETRACTING
To retract the boom fully you will
need to extend the boom to 90%
setting for each boom section. Then
start retracting the top boom first and
work your way down. Doing this gives
you access to the 45% spring lock.
