TRAVELING ON A SLOPE
1. When traveling on a slope, it is necessary to determine
the grade of the path. The EB500 Mini Dumper can
travel up or down slopes not exceeding 25° (Figure 12).
DO NOT travel on steeper slopes.
To determine the % grade of your path of travel, use
the formula and graph in Figure 12.
2. Lateral side to side travel cannot exceed 6°.
