interference with other equipment or operations.
2. Verify all controls are in the "off" position and all
operating features secured from inadvertent motion
by brakes, pawls, or other means.

circuits before loosening or removing hydraulic
components.

guards have been reinstalled, trapped air removed
from hydraulic system (if required), safety devices
reactivated, and maintenance equipment removed.
ADJUSTMENTS AND REPAIRS
1. Any hazardous conditions disclosed by the
inspection requirements shall be corrected before
operation of crane is resumed. Only designated
personnel shall do adjustments and repairs.
2. Adjustments shall be maintained to assure correct
functioning of components, the following are
examples:
A. Functional operating mechanism.
B. Safety devices.
