To Determine The Slope Grade; Drive Enable - Genie S-85 Operator's Manual

Seventh Edition • Third Printing
Note: Slope rating is subject to ground conditions
and adequate traction.The term gradeability
applies to the counterweight uphill configuration
only.
Be sure the boom is below horizontal and the
platform is between the circle-end wheels.
Move the drive speed select switch to machine on
incline symbol.

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.
Part No. T107108
Operating Instructions
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 slope 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 to either side
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.
