NBT40 SERIES OPERATOR MANUAL OPERATING CONTROLS & PROCEDURES
OPERATING PROCEDURES
You need to be familiar with the safety precautions outlined
in this manual before operating the crane.
Equipment Familiarization
All members of the crew should become familiar with the
location and operation of the controls, the correct operating
procedure, the maximum lifting capacities, and the Safety
Precautions in Section 2 of this manual. Carefully follow the
operating procedures outlined below and the information in
the load charts located in the crane cab.
Crane Cab Access
To enter the cab, pull the ladder out from under the crane cab
door and use the grab handles (1, Figure 3-12) inside the
cab to enter the cab. Take all precautions not to fall off the
crane. Falling from any elevation can cause serious injury or
death.
Equipment Checks
Prior to placing the unit in operation, do a complete walk-
around visual inspection and look for structural damage,
loose components, leaks, or other conditions that requires
immediate correction for safe operation. The following
checklist of items are suggested to ensure the crane is
prepared for performing work operations. Check:
• for any unusual conditions such as pools of hydraulic
fluid or lubricating oil under the chassis, any outrigger
which may have crept down or up and any signs of
damage or improper maintenance.
• the tires are inflated to the proper pressure.
• the level of the hydraulic reservoir.
