5.4.6 Bucket
NOTICE
Avoid overloading. Observe the maximum permissible payload.
Operate the control lever carefully.
The light cargo bucket is used for light materials such as grain, maize and pellets.
The earth bucket is used for heavy materials such as gravel, sand, soil and stone.
Function
The light cargo bucket / earth bucket attachments are in
tended for loosening, picking up, transporting and dumping materials.
Attaching the bucket
Read the chapter »Changing attachments« (Section 5.4.5, page 94).
Operating element
Operate the bucket using the control lever for the loader lift arms. Read the chapter »Operating lever for Loader lift
arms« (Section 5.4.1, page 88).

Operation
Before performing work for the first time, practice handling the bucket.
When dumping the bucket and loading vehicles, you can perform two work movements at the same time if necessary, e.g. lifting and dumping or lowering and curling to load. To do so it is necessary to overlay the movement on the control
lever (Fig. 41).
The float position facilitates stripping during resurfacing work. To do so, lower the bucket with the tip to the ground.
Then engage the control lever in position 2a. The bucket now lies on the ground, free to move and burdened only by its own weight.

Level indicator
(optional equipment)
If different attachments are used, you can add a marking on the guide tube for each attachment
(Fig. 42 a and b). This will enable you to adjust the
level display quickly when changing attachments.
Observe the level display (Fig. 42) so that you can judge the
tilt position of the attachment better from the operator’s seat.
Setting the level display:
1. Lower the attachment to the ground in a parallel position.
2. Release lever item 1 by turning it to the left.
3. Adjust the guide tube item 2 in such a way that the display rod item 3 aligns with the end of the guide tube.
4. Lock the lever by turning it to the right.
5. Now you can align the attachment according to the display position during your work.

Working with the bucket
WARNING
Tipping hazards. Improper use of the loader lift arms and bucket may cause the loader to tip, possibly causing injury or equipment damage.
►
Operate the loader with the bucket as close as practical to the working surface or ground to reduce the risk of tipping the wheel loader.
►
To reduce the risk of tipping the wheel loader, do not raise the loader lift arms and fully loaded bucket unless the ground or operating surface is firm and flat.
►
Do not drive across slopes with the loader arms raised.
►
Do not travel up or down slopes with the loader arms raised.
Loading work
Fig. 43
Loading work 1
Lower the bucket to pick up loose material so that it is parallel to the ground and move it into the material to be loaded.
Here the driving speed should correspond to the type of
material and the respective working conditions (Fig. 43).
Adjust your driving speed when driving into the loading material, according to the type of material and the respective conditions.
Make sure that no excessive wheel slip occurs.
Tire wear and fuel consumption will increase unnecessarily and the loader‘s performance will not be fully utilized.
W L 25
Now raise the loader lift arms slightly so that the weight is on the loader‘s front axle. This is to avoid excess wheel slip. You can also manually restrict wheel slip by inching.
To fill the bucket, curl the bucket as shown in Fig. 44 as the
loader arms are slowly raised. Carry the loaded bucket in this position to the location or truck where the material in the bucket is to be deposited.
Carry the loaded bucket low until necessary to lift it to the necessary loading height.
If material is to be loaded which the bucket cannot easily penetrate, you can create an up-and-down movement of the bucket cutting edge by alternately curling the bucket slightly upward and downward while penetrating into the material. This makes it easy for the bucket to penetrate the
material (Fig. 45).

Excavation work
Soft material:
Lower the bucket to the ground to lift out soft material and tilt the bucket forward until you have a digging angle. If you start driving the loader forward now, the bucket‘s digging edge will break into the ground. Now make the tilting angle flat to remove as even a layer as possible and to avoid a
large amount of wheel slip (Fig. 46).
Resistant material:
Lower the bucket to the ground to lift out resistant material and tilt the bucket forwards until you have a digging angle.
When you drive the loader forwards now, slightly press the bucket downwards so that it can break into the ground.
Should the bucket‘s digging angle penetrate the ground, make the tilting angle flatter. Use the bucket curl control lever to produce an up-and-down movement of the digging
edge of the bucket (Fig. 47).
