PROHIBITION OF SWINGING OR TRAVELING WHEN ROCK IS ON TOP OF
TRACK ASSEMBLY
If the machine travels or swings with crushed stones, soil, or
sand on the track, they hit and damage the undercover and
frame. In the worst case, the hydraulic components are dam-
aged and a serious accident can result.
During operation, keep checking the track top for crushed
stones, soil, and sand.

Although lifting operation with this machine is prohibited, it is
permitted only when the special lifting hook is installed.
