undercarriage and the working attachment must face to
the front in travel direction. The travel gears must be at
the rear in the direction of travel.

For maximum stability carry the bucket as close to
ground level as possible. Operate the travel control ped-
als sensitively. Avoid jerky acceleration and deceleration
of travel motions. Travel speed must be conform to the
