outrigger cylinders.
4. Place the boom derricking lever in the “Raise”
position (pull it toward you) to raise the boom
slightly for greasing the derricking cylinder
mounting pin and slide plate that is located on
top of the boom.
5. Place the boom telescoping lever in the
“Extend” position (push it toward the front) to
extend the boom for greasing both sides and
