Don’t slewing on slope.
and place the bucket arc on ground.
(b)
Slew upper structure 90
and lower bucket to lift one side
of crawler off ground. Don’t dig into the ground with
bucket teeth when the machine is in backhoe condition.
(c)
Place
chock
under
the
framework
to
support
machine.(Figure 3.6.8)
Avoid tilting
Avoid transverse traveling on slope. When the machine travels on
slope, the traveling direction should be accordant with the gradient.
When upgrade and downgrade, keep the bucket pointing to the
traveling direction and lifting 200-300mm to the ground (As figure
3.6.9). Lower bucket at once if the machine is skidding or instable.
(As figure 3.6.10).When the machine slew with heavy load, it
should operate carefully and operate with low slewing speed.
Operate in water or mud
You should note following information when operate in water or
mud:
(1)
The working area should be sufficient hard to avoid
excavator going down.
(2)
The water flow should be slow.
(3)
Undercarriage immerged height doesn’t allow
exceeding chain support wheel.
(4)
Slewing support, inner gear ring, and slewing
connector won’t be allowed immerging.
(5)
When operate in these conditions, please check the
excavator position usually.
Backhoe operation
(1)
Place the bucket teeth on ground while the angle
between bucket bottom and ground is 45
.
(2)
Apply arm to be the main digging force, pull bucket to
the machine direction.
(3)
When dirt adhered on the bucket, remove arm and (or)
bucket quickly to throw the dirt.
(4)
When dig straight trench, place crawler parallel to the
trench. After dig to required depth, remove machine to
continue digging.
