Driving on a slope
Determine the uphill, downhill and side slope
ratings for the machine and determine the slope
grade.
Maximum slope rating,
counterweight uphill
(gradeability):
2WD: 25% (14°)
4WD: 40% (22°)
Maximum slope rating,
counterweight downhill:
2WD: 20% (11°)
4WD: 30% (17°)
Maximum side slope rating:
25% (14°)
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 non-steer 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
OPERATING INSTRUCTIONS
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.
