Important Information On Machine Operation; Rops Bar - Kubota U 10-5 Operator's Manual

OPERATING THE EXCAVATOR
IMPORTANT :
• Do not lock the service port pedal when the
service port is not in use.
Locking the pedal can cause the hydraulic oil
temperature to rise, which leads to problems
with the hydraulic components.
IMPORTANT INFORMATION ON
MACHINE OPERATION
WARNING
To avoid personal injury or death:
• After operation, clean the machine, lubricate all
of the movable parts, and check the oil level.
• Do not try to crush concrete or boulders using side
swings with the bucket. Also avoid using side
sweeps of the bucket to move earth piles.
• Under all circumstances avoid the following
operations:
– Excavation using the gravitational impact of the
machine
– Compacting of gravel or soil using the dropping
action of the bucket
– Excavation using the traveling power of the
machine
• If soil adheres to the bucket, do not try to violently
shake off the soil. This can cause damage to the
machine. Instead, use the following technique:
Shake off adhering soil when the bucket is being
emptied by moving the bucket out to the maximum
stroke of the cylinder. Should this not suffice, swing
out the arm as far as possible and operate the
bucket back and forth.
• Do not hit the dozer with the boom cylinder.
Make sure that the boom cylinder does not hit the
dozer when carrying out deep excavation. If
necessary, swivel the upper structure so that the
dozer is at the back of the machine.
• Pay attention when pulling in the bucket.
When pulling in the bucket (for driving or
transportation) avoid hitting the dozer.
• Avoid collisions.
When moving the machine, pay attention so that
the dozer does not collide with boulders or other
such obstructions.
Such collisions substantially shorten the life span of
the dozer and the cylinder.
• Support the machine correctly.
When stabilizing the machine with the dozer, Iower
the whole dozer fully to the ground.
• If the water or mud level reaches higher than the
top of the tracks, the swivel bearing, swivel motor
gear, and ring gear may be exposed to mud, water,
and other foreign objects.

IMPORTANT INFORMATION ON MACHINE OPERATION

The machine must be properly pressure washed
after each use.
– Thoroughly clean the area around the swivel
bearing, swivel motor gear, and ring gear to
remove foreign objects.
– Inspect the swivel motor oil sump (if equipped)
for water contamination. If water is present,
refer to operator's
replacement procedure.
– Refer to operator's manual for proper swivel
bearing, swivel motor gear, and ring gear
lubrication procedures.
– Reinstall any protective covering if removed
earlier.

ROPS BAR

WARNING
To avoid personal injury or death:
• Before extending or folding the ROPS bar, stop
the engine and remove the key.
Perform this task on flat, stable ground.
• Fold the ROPS down only when absolutely
necessary. After folding the ROPS, raise it back
up and lock it again as soon as possible.
• When extending or folding the ROPS bar, be
careful not to get your hands caught by the
joints.
• Before folding the ROPS bar, keep the front
attachment at the center of swing and the
bucket on the ground.
• When operating the machine with the ROPS
folded, observe the following points:
– Do not wear the seat belt.
– Operate with the tracks at the widest width
possible.
– Avoid steep or uneven terrain.
Kubota recommends operating the machine
with the ROPS up and the seat belt fastened in
almost all situations.
