Lifting Capacities
When a machine is operated on tires, the machine
capacities are different from a machine that is operated
on stabilizers. Also, the machine capacities for each
type of attachment are different.
Machine instability can result in injury or death. To
ensure stability during operation the following
conditions must be observed:
Tires must be correctly inflated and have the correct
amount of ballast (if equipped).
The machine frame must be level.
The frame level switch must never be operated when
the boom is raised.
The frame level switch must never be operated when
stabilizers are lowered.
Stabilizer switches must never be operated when the
boom is raised.
The correct load chart for the machine as equipped
must be referenced and the weights and load centers
specified must never be exceeded.
The machine must never be moved when the boom is
raised.

The load charts are located on the dash panel at the
right side of the instrument cluster. Ensure that the
correct load chart is used. The chart is intended for the
type of attachment that is represented by a symbol at
the top of the chart. Symbols are also shown for
operation on tires or on stabilizers. The load charts
may be in metric units (meters and kilograms) or
conventional units (feet and pounds).
When the machine is operated on tires, the weight of
the intended load determines the maximum height
above ground. The weight of the intended load also
determines the maximum distance that is between the
load center of gravity and the front wheels.
When the machine is operated with lowered
stabilizers, the weight of the intended load determines
the maximum height above ground. The weight of the
intended load also determines the maximum distance
that is between the load center of gravity and the
stabilizer pads.
The machine boom has two scales which must be
used for reference with the load chart in order to
assess the lift operation. The boom extension
reference scale gives an indication of the boom length.
The letters "B", "C" and "D" correspond to the same
letters on the load chart.

Boom angle reference scale (1) gives an indication of
the angle of the boom.
Follow the instructions below in order to assess the
intended load:
1. Carefully position the machine. The machine
should be as close as possible to the intended
load. For more information on operating the
machine, refer to the appropriate topic in the
Operation Section of the Operation and
Maintenance Manual.
2. In order to move the attachment into position for
the operation, raise the boom and extend the
boom, as required. Do not make the liftoperation.
3. Look at the boom extension reference scale and the
boom angle reference scale and note the readings.
Refer to the load chart and use these two values in
order to locate the equivalent load zone.
4. If the intended load is equal to the value in the
equivalent load zone the lift operation can be
attempted with caution. Also, if the intended load
is less than the value in the equivalent load zone
the lift operation can be attempted with caution.
