To determine the slope grade:
Measure the slope with a digital inclinometer OR
use the following procedure.
You will need:

carpenter’s level

straight piece of wood, at least 3 feet/1 m long

tape measure
Lay the piece of wood on the slope.
At the downhill end, lay the level on the top edge of
the piece of wood and lift the end until the piece of
wood is level.
While holding the piece of wood level, measure the
vertical distance from the bottom of the piece of
wood to the ground.
Divide the tape measure distance (rise) by the
length of the piece of wood (run) and multiply by
100.
Example:
Piece of wood = 144 inches (3.6 m)
Run = 144 inches (3.6 m)
Rise = 12 inches (0.3 m)
12 in ÷ 144 in = 0.083 x 100 = 8.3% grade
0.3 m ÷ 3.6 m = 0.083 x 100 = 8.3% grade
If the slope exceeds the maximum uphill, downhill
or side slope rating, then the machine must be
winched or transported up or down the slope. See
Transport and Lifting section.
Drive Enable
Light on indicates that the boom
has moved just past either
non-steer wheel and the drive
function has been interrupted.
To drive, hold the drive enable switch up or down
and slowly move the drive control handle off
center.
Be aware that the machine may move in the
opposite direction that the drive and steer controls
are moved.
Always use the color-coded direction arrows on the
platform controls and the drive chassis to identify
the direction the machine will travel.
Low Voltage Interrupt (if equipped)
Machines equipped with Low Voltage Interrupt will
lose primary and secondary boom up functions
from the platform when batteries are low.
