OPERATING THE MACHINE
3. Ensure the slope grade is within the machine
gradeability.
NOTICE
Gradeability refers to the maximum permissible
percentage of the slope (or called slope grade as
below) when the machine is on solid ground with
sufficient traction and the platform is carrying only
one person. As the weight of the machine’s platform
increases, the machine’s gradeability will be reduced.
To determine the slope grade:
1. Prepare a carpenter’s level, a straight wooden
board (at least 1m [3.3ft] long) and a tape measure.
2. Measure the height (H) and length (L) of the slope.
Figure 7-5
3. Slope grade= H/L x 100%.
NOTICE
The machine must not run on the maximum
permissible slope grade for over 2min to prevent the
tires running suspended.
