As the boom is extended, boom extend letters will appear on the left side of
the boom visible to the operator. The letters are graduated in four foot
increments. These letters indicate the point of boom extension and
correspond to the capacity chart. For example, when the letter “A” first
appears, the boom is at the point of boom extension corresponding to the
arc of line “A” throughout the entire capacity charts (Figure 54) through
(Figure 61).
The boom angle indicator, located on the left side of the outer boom,
indicates the angle of the boom and also corresponds with the angles
indicated on the capacity chart.
To accurately use the capacity chart, the operator must first determine three
important things:
1. Weight of the load being lifted.
2. Height of the structure where the load is to be placed.
3. Distance where the load will ultimately be placed in front of the front
tires.
WARNING:
DO NOT exceed rated capacities. Any attempt
to lift or carry loads in excess of those shown on the capacity
chart in the operator's compartment may cause vehicle tipover,
loss of load or structural damage which could result in death or
serious injury.
