driver's cab.

S
Risk of damage to driver's cab!
Lift the main boom far enough to ensure that the pivot point of the derrick-
ing cylinder does not damage the driver's cab.
G
Danger of hands and arms being crushed.
Whilst rigging the crane, maintain sufficient distance from the main boom
and do not reach in between the connecting points. This will prevent you
from being crushed between the turntable and the main boom.
