Operating The Controls During Excavation Work; Note On Using Wider And Deeper Buckets - Kubota U27-4 Operating Instructions Manual

Operating the controls during excavation work

Always observe the following safety instructions when working with the excavator.
STOP
Never crush concrete or boulders using side boom swings with the bucket.

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 (accessory).
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 the lower edge of the swivel frame.

After using the machine in water, always grease the pins at the bucket and arm with grease until the old lu-

bricating grease emerges.
When digging in reverse direction, pay attention that the boom does not get into contact with the dozer.

It is forbidden to use the excavator for lifting operations, unless it is equipped with a pipe safety valve for crane

operation (accessories) according to EN 474-5.
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 operate the bucket back and forth.
When excavating, always lower the dozer completely onto the ground.

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.
