Tip-over Hazards
DO NOT exceed the maximum platform capacity. The weight of options and accessories will
reduce the rated platform capacity and must be factored into the total platform load. Refer to
the decals on the options.
DO NOT elevate the platform when the machine is on a surface that is soft and / or on a slope.
DO NOT depend on the tilt alarm as a level indicator. STOP if the tilt alarm sounds and the
red light illuminates when the platform is raised. Use extreme caution to lower the platform.
Move the machine to a rm, level surface.
Driving: DO NOT drive the machine on a slope that exceeds the maximum uphill or downhill
slope rating. Slope rating applies to machines in the stowed position.
Driving in stowed position: use extreme care and reduce speed when driving across uneven
terrain, debris, unstable or slippery surfaces, and near holes or drop-offs.
Driving with the platform elevated: DO NOT drive on or near uneven terrain, unstable

Driving On A Slope
DO NOT drive the machine on a slope with the platform elevated.
The platform must be in the fully stowed position before driving on a slope.
Determine the slope and side slope ratings for the machine and determine the slope grade.
Maximum forward/rearward slope rating, stowed position 25%.
Maximum side slope rating, stowed position 5°.
Note: Slope rating is subject to ground conditions and adequate traction.
Set the Drive Speed Switch to the DOWN (Turtle) position to engage slow speed drive mode.
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 3.3 ft / 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 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:
Run = 12 ft / 3.6 m
Rise = 12 in / 0.3 m
12 in ÷ 12 ft = 0.083 × 100 = 8.3%
0.3 m ÷ 3.6 m = 0.083 × 100 = 8.3%
If the slope exceeds the maximum slope or side slope rating, the machine must be winched or
transported up or down the slope. See Transport and Lifting section.
