4.9.3 Permissible depth of water
Note:
When driving your machine out of water, an
inclination of slope exceeding 15° would have
the rear of its upper turntable immersed in
water, thus the fan could be damaged due to
water.
Pay special attention to your machine when
driving it out of water.
● Don not drive your machine into water
where water level could reach the center of
carrier roller (1).
● Add grease to parts that have been soaked
long in water, till old grease is completely
squeezed out of the bearing (especially the
area around the pin of bucket).
● Never operate your machine in water un-
less the foundation of job site is strong
enough so that the level of water could not
reach the center of carrier roller.
● If the swing bearing, swing gear and cen-
tral swing joint are soaked in water, the
drain plug should be opened to remove
mud and water. Clean the swinging area
and reinstall the plug. Lubricate the mesh
gear and swing bearing inside the swing
unit.
4.10 Traveling on Slope
● When operating your machine on a slope,
never turn your machine or operate the
work equipment as that would cause your
machine to loose balance.
● It is dangerous to swing downward on a
slope when your bucket is loaded. If such
operation is necessary, you have to pile
up a platform on the slope with earth so
that your machine could be kept on a level
ground.
