Tip For S150 Model
New operators must operate the excavator in an open
area without bystanders. Operate the controls until the
excavator can be handled at an efficient and safe rate for
all conditions of the work area.
Operating Near An Edge Or Water
Keep the excavator as far back from the edge as possible
and the excavator tracks perpendicular to the edge so
that if part of the edge collapses, the excavator can be
moved back.
Always move the excavator back at any indication the
edge may be unstable.
