Operation
75 Model 10042 Rev. 11/03
As the boom is extended, boom extend letters (2) will appear on the left side
of the intermediate boom (4) 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 all of the capacity charts that
follow.
The boom angle indicator (3), located on the left side of the outer boom (5),
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
charts in the operator's compartment may cause vehicle tipover,
loss of load or structural damage which could result in death or
serious injury.
