 When the boom is fully retracted, it can be two seconds before the
boom starts to move.
 Lift the load vertically. Do not try to lift the load diagonally. Do not pull
a load across the ground.
 Do not use the bypass key switch when you do usual crane
operations.
 An extended boom can retract a short distance if the boom is extended
for a long period of time. The items that follow are a possible cause for
the movement:
 A change in the hydraulic oil temperature
 A change in the angle of the boom
 Lubrication status.
Solutions:
 Make sure that the hydraulic oil temperature does not increase too
high.
 Extend the boom to the correct length.
 Do not extend / retract the boom with a suspended load.
