Operation
Operating Levers/Pedals
Horn Button
The horn button is located on the right hand excavator lever. Refer to: Component Locations (Page 15). Press
and hold the button to activate the horn. It functions only when the ignition switch is on.
Excavator Controls
The excavator controls consist of the excavator levers.
The excavator levers are spring loaded to the central position. In this position related services will not operate.
The speed and movement of the associated hydraulic function depends on how far you move the lever. The
further you move the lever, the faster the action.
The boom ram incorporates damping at the limit of boom raise, reducing the speed of the ram and eliminating
shock loadings.
Raising the left armrest when leaving the cab prevents the services operating. When re-entering the cab, make
sure the armrest is lowered correctly for correct operation.
Most excavating movements are achieved using a combination of both the levers and the pedals at the same
time. Practice such movements until you are familiar with the operations that can be achieved safely.
