CD5520/YB5520 OPERATOR MANUAL OPERATING CONTROLS AND PROCEDURES
Boom Lift Operation
Know the capacity of the crane. The operator must be
familiar with the crane’s capacity chart before lifting a load.
See Capacity Chart, page 4-1. A falling load or crane tip-over
can cause injury or death.
NOTE: Look for overhead obstructions before raising the
boom. Possible damage or electrocution could
occur if the boom comes in contact with overhead
power lines.
To Raise the Boom
Press the accelerator pedal to increase the engine speed to
maximum rpm. Slowly pull back on the boom control lever
(Figure 3-35) until the desired raising speed is obtained. The
further the control is pulled back the faster the boom will
raise.
To Stop Boom Movement
Slowly move the control lever to the neutral position and
decrease the engine speed to idle.

WARNING
When lifting at high boom angles with an extended boom,
it is crucial to maintain proper side slide pad adjustment.
Visually check the lateral straightness of the boom before
raising the load. Lifting with a boom which is not visually
straight may cause boom failure and could result in injury
or death.
