CONTROLS AND INDICATORS
The engine is electronically controlled by the Electronic
Control Module (ECM); it is the control center of the entire
engine system. The ECM processes all of the inputs and
sends commands to the fuel systems as well as vehicle and
engine control devices. This Operator Manual does not
include information on the engine ECM, however a separate
manual as prepared in detail by the engine manufacture is
shipped with the crane at the factory.
All the controls and indicators to operate and monitor crane
functions are found inside the crane cab Figure 3-1 and
include the following:
1. Foot Pedals
2. Outrigger Control
3. Seat Joystick and Armrest Controls
4. Side Display Panel
5. Steering Column
6. Overhead Control Panels
