CAUTION
(1) Always monitor the wire rope in process of raising main boom to make sure that the
wire rope on boom head is kept in the rope groove all the time.
(2) Before main boom is raised to 30° position, make sure that the hook is in contact
with the ground. After main boom is raised to 30° position, the hook can be lifted
away from the ground.
(3) The boom-raising movement should be performed slowly and stably. And during the
operation, the crane operator must observe the data shown on the screen, while
other workers should pay attention to environmental changes.
(4) Standing beneath the boom frame is prohibited.
(5) Working radius stipulated in the load capacity charts should be adhered to, even if
no load is attached on the load hook! If this is not observed, the crane may topple
over!
