Position
When the booms are folded up in the transport
position, the full weight of the booms must be
supported by the inner boom. The outer aluminium
boom may sit on the boom rest rubber but must
not support any weight.
INNER BOOMS
• If the boom sits level in the working position but
when folded up, one side is lower than the other,
there is one adjustment that can be made.
• Shims can be placed at the bottom boom mount
of the lowest boom - refer to diagram A. This will
lift the boom in the open position.
• If the boom is not level in the working position,
the most likely cause if this is an out of balance
boom. Refer to previous boom adjust information.

not saddle correctly and will not be supported in
transport.
The boom support saddle is bolted to the outer
boom and when folded, couples to the inner boom.
This saddle must slide onto the inner boom freely to
prevent damage to the booms.
NOTE: This process will be re uire in the first 6
months of operation as the booms stretch and
ware in.
OUTER BOOMS
• If the outer boom hangs too low in the folded
position shims must be added to the cable drum
pivots. To raise the outer boom, add shims to
both the upper and lower pivots. This adjust the
angle of the pivot axis causing the outer boom to
fold up higher. By adding shims to both the upper
and lower pivots, the outer boom height is not

affected in the working position.
• To lower the outer boom in the folded position,
remove shims from both the upper and lower
pivots.
• 1 x 1 mm shim at the upper and lower pivots
equals approximately 15 mm change in height.
