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.
