Operating The Controls During Excavation Work; Note On Using Wider And Deeper Buckets - Kubota U50-5 Operating Instructions Manual

Operation

Operating the controls during excavation work

Always observe the following safety instructions when working with the machine.
STOP
Breaking concrete or rocks with the bucket is prohibited.

Do not use the dropping action of the bucket for excavation.

Never fully extend the cylinders. Always keep a certain safety margin, especially when operating with a break-

er (optional).
Never use the bucket as a hammer to drive posts into the ground.

Do not drive or dig with the bucket teeth rammed into the ground.

When loading soil, do not dig the bucket deeply into the ground. Instead, make relatively shallow slices with

the bucket out as far as possible. This technique reduces the stress on the bucket.
When working in water, the water should only reach up to the lower edge of the swivel frame.

After using the machine in water, always grease the pins on the bucket and arm with grease until the old lu-

bricating grease emerges.
When digging with the boom above the dozer, make sure that the boom cylinder does not come into contact

with the dozer.
Adhering soil can be shaken off when the bucket is being emptied by moving the cylinder to the end of the

stroke. Should this not suffice, dump the arm as far as possible and swing the bucket back and forth.
To increase the machine's stability, we recommend lowering the bulldozer blade onto the ground. The bull-

dozer blade may only be used to increase the machine's stability if the bulldozer blade cylinder is equipped
with a pipe safety valve. The dozer control lever must not be moved into floating position in the process. The
machine's stability is not increased by the bulldozer blade while in the floating position.

Note on using wider and deeper buckets

When using a wider or deeper bucket, take good care
when swinging or retracting the front attachments to
make sure that the bucket does not hit the cab.
