OPERATION
Handling Rubber Crawlers
¡ When climbing in reverse, do not change
course at the point where the slope starts.
¡ Avoid traveling with one crawler on a slope
or projecting object and the other crawler
on a flat surface (with the machine at a tilt
of 10° or greater). Travel with both crawlers
on flat surfaces.
¡ Do not change directions when the crawler
belts are slack as shown in the diagram.
