5.4.5 Changing attachments
This Operator’s Manual describes only the use of the following attachments:
•
Light cargo buckets
•
Earth buckets
•
Earth buckets with digging teeth
If you wish to use optional attachments with your loader, please observe the following:
Contact your Wacker Neuson dealer before using any attachment not in the approved list. The dealer and Wacker
Neuson technical staff can determine the compatibility of the proposed attachment.
Wacker
Neuson
is not liable for changes made without its approval.
•
Use only Wacker Neuson -approved attachments for your loader. Wacker Neuson is not liable in the event of other attachments being used.
•
Do not exceed the rated load capacity of the wheel loader as stated in the specifications.
Exceeding the rated capacity can create unintended hazards and reduce the operating life of the loader.
•
Replace the hoses on the loader with original equipment hose assemblies supplied by your
Wacker Neuson dealer. These assemblies meet the exacting standards of performance of the new machine.
•
Make sure to match the SAE designations when ordering replacement hoses and/or fittings. Con
tact your Wacker Neuson dealer for assistance in obtaining replacement parts.
•
Observe the safety instructions for changing attachments.

Operating and operation
NOTICE
Unapproved attachments could overload the loader.
This can result in damage to the loader.
1. Before assembly, start-up or maintenance, read the
Operator’s Manual for the relevant attachment.
2. Practice using the attachment before working with it the first time. Familiarize yourself ahead of time with all the functions and control elements.
•
When loading, adjust your driving speed to the material being loaded and traction conditions.
• Avoid contact with hydraulic fluid in the event of pressurized leakage. In the event high pressure fluid comes in contact with skin, or if hydraulic fluid enters the eye, seek immediate treatment in an emergency room.
•
Do not use an attachment unless it is in serviceable condition.
•
Before attempting to uncouple an attachment, read the instructions for the uncoupling process.
Confirm that the attachment will not move when removed from the loader lift arms.
•
To avoid personal hazards and potential machine damage, confirm that the attachment is properly and firmly connected to the loader lift arms before use.
•
Do not perform service or repairs on the attachment unless the loader and loader lift arms are secured as described in Section 9, page 139
»Securing the Loader«.

Coupling of attachments with manual quick-change system
WARNING
Personal injury hazard.
Falling attachments can strike people.
►
Check the locking pins item 4 (Fig. 41) to avoid unintentional disconnection of the attachment.
Confirm that the hydraulic couplings are cor
rectly matched to operate the attachment.
Pressurized hydraulic oil can penetrate the skin, causing infections.
►
If this occurs, seek immediate emergency room treatment.
►
Oil entering the eyes must also be treated immediately in an emergency room.
ENVIRONMENTAL NOTE
Hydraulic oil is hazardous to the environment. Do not allow it to be released uncontrollably into the environment.
1. Drive the loader up to the attachment (Fig. 41).

that the pins engage in the tabs of the attachment Item 4.
Check that the locking pins fit correctly in the tabs Item 4.
For hydraulically activated attachments:
6. Switch the control lever for the optional hydraulics to
“float position” (Fig. 42) to depressurize the lines for the optional hydraulics.
7. Insert the attachment‘s quick couplers in the appropriate connections for the attachment hydraulic lines on the loader lift arms.
8. Check that there are no leaks in the attachment‘s hydraulic system and the quick couplers of the attachment hydraulic lines. Slowly actuate the attachment control to confirm the controls are working correctly and the couplers and hydraulic lines are not leaking.

Operating and operation
Uncoupling attachments with manual quick-change system
• Lower the attachment until it is firmly resting on a hard surface.
•
Close attachments with movable components such as clamshells.
•
Actuate the attachment controls through the full range of motion to release residual hydraulic pressure.
•
If the attachment is equipped with integral supports, extend them to the support position.
•
Place the attachment only on a hard, even foundation.
ENVIRONMENTAL NOTE
When uncoupling the hydraulic connections, hold a pan under the optional hydraulics‘ quick couplers to catch any oil that might run out. Dispose of it in an ecologically sound way.
1. Lower the attachment.
2. Switch the control lever for the optional hydraulics to
“float position” (Fig. 42) to depressurize the lines for the optional hydraulics.
3. Disconnect the hydraulic couplers and place covers over the exposed ends to exclude foreign material.
4. Place the hydraulic hoses over the attachment.
5. Move the levers of the locking pins Item 3 (Fig. 41) upward, so that the pins are pulled out of the tabs of the attachment Item 4.
6. Slightly lower the loader lift arms to disengage the upper attachment support coupler halves. Activate the bucket curl, rotating the lower portion of the loader frame coupler away from the attachment coupler.
(This releases the receptacle frame item 1 (Fig. 41) from the mounting brackets Item 2 (Fig. 41)).
7. Back the loader away from the attachment if the receptacle frame is free.

WARNING
Personal injury hazard.
Falling attachments can strike people.
►
Check the locking pins item 4 (Fig. 41) to avoid unintentional disconnection of the attachment.
Confirm that the hydraulic couplings are cor
rectly matched to operate the attachment.
Pressurized hydraulic oil can penetrate the skin, causing infections.
►
If this occurs, seek immediate emergency room treatment.
►
Oil entering the eyes must also be treated immediately in an emergency room.
If the loader is equipped with a hydraulic quick-change system for various attachments, the operator can thus couple and uncouple attachments in a quick and uncomplicated manner, from the operator‘s seat.
ENVIRONMENTAL NOTE
Hydraulic oil is hazardous to the environment. Do not allow it to be released uncontrollably into the environment.
107
Operating and operation
1. Drive the loader up to the attachment (Fig. 41).
2. Bring the receptacle frame Item 1 under the mounting brackets Item 2 (Fig. 41).
3. Raise the loader lift arms and curl the attachment bracket to mate the coupler surface together.
4. Extend the locking pins Item 3 (Fig. 41) downward by moving the control lever for the optional hydraulics Item Z
(Fig. 43) into direction “R”, so that the pins engage in the tabs of the attachment Item 4 (Fig. 41).
5.
Check that the locking pins fit correctly in the tabs Item 4.
For hydraulically activated attachments:
6. Switch the control lever for the optional hydraulics to
“float position” (Fig. 42) to depressurize the lines for the optional hydraulics.
7. Insert the attachment‘s quick couplers in the appropriate connections for the attachment hydraulic lines on the loader lift arms.
