SWE90UF-2PB Operation & Maintenance Manual
Avoid transverse traveling on slopes. When the machine travels on slopes, 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, operate carefully with low
slewing speed.
Operate in water or mud
You should note following conditions when operating the
excavator in water or mud:
(1) The working area should be hard enough to avoid
excavator sinking.
(2)
The water flow should be slow.
(3) Undercarriage submerged height can’t exceed the
carrier roller.
(4)
Slewing support, inner gear ring, and slewing
connector is not allowed to be submerged
(5) When operating 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 digging straight trench, place crawler parallel to
the trench. After digging to required depth, remove
machine to continue digging.
【Important】
When lowering boom, you should avoid stopping it suddenly. Otherwise the impact load may
damage excavator (As figure 3.5.10).
When operating the arm, avoid lowering hydraulic cylinder to the bottom to prevent the damage
of hydraulic cylinder.
Avoid bucket colliding with the crawler.
