2. Holding the downhill end, raise the 2 x 4 until the level
indicates that the board is level (refer to Figure 8.8).

3. Use the tape measure to measure the distance
(height) from the end of the 2 x 4 to the ground.
Record the height distance.
4. Measure the length of the 2 x 4 and record this mea-
surement.
5. Use the formula in Figure 8.6 to calculate the percent
of the grade.
Machine Gradeability
The gradeability specification for the 460SJ aerial plat-
forms is 50%. An actual gradeability of 50%, indicates
that in most normal working conditions the machine can
be driven on a slope with an angle of 25 degrees.
Electrical Power Outlet
The electrical outlets at the platform have 2, 3-prong, 110
volt AC electrical connectors. Their combined output is
limited by a 15 amp circuit breaker.
Power may be supplied to the outlet using an external
power source or by operating the optional AC generator.
To use the outlet, plug a source of power into the pow-
er-input connector on the left side of the turntable. Unplug
the source of power before moving the aerial platform.
AC Generator
The optional generator supplies power to the electrical
outlet when the engine is running. Boom and drive func-
tions will operate at reduced speeds while the generator
is operating.
To supply power to the electrical power outlet, start the
engine and place the machine/generator switch (refer to
Figure 8.9) in the generator position.

The engine will run at high idle while the generator is
operating. The generator will continue to operate as long
as the engine is running and the switch is in the genera-
tor position.
Panel Carrier
The panel carrier allows the platform operator to position
a panel at the work place.
The panel carrier includes two cradles at the bottom rear
of the platform and a hook to place over the panel (refer
to Figure 8.10).

Figure 8.10 – Panel Carrier
The panel carrier is designed to carry a maximum size
panel of 4' x 8' (1.2 m x 2.4 m), with a maximum area of
32 ft
(3m
).

Place the panel on the cradles so its longest dimension is
across the cradles. The hook should be placed over the
panel at it's shortest dimension, not to exceed 48" (1.2 m)
Platform Capacity
The platform rated load capacity is the total weight of
the personnel and equipment that may be lifted in the
platform. The work load is stated on the platform rating
placard mounted on the toeboard at the rear of the plat-
form. Do not exceed the rated load capacity.
