Maintenance 7
Tightening the tracks
1. Park the vehicle on firm, level, and horizontal ground.
2. Raise the machine evenly and horizontally by means of the boom and
stabilizer blade.
3. Stop the engine.
4. Operate the control lever repeatedly to release the pressure in the
hydraulic system.
5. Pump grease with a grease gun through lubricating valve A.
6. In order to check that the tension is correct:
- Start the engine
- Let it run at idling speed without any load
- Slowly move the machine forward and reverse and switch it off
again.
7. Check the track tension again.
➥ If it is not correct:
8. Adjust again.
9. Should the tracks still be slack after pumping more grease, replace the
tracks or the seals in the cylinders. Contact a Wacker Neuson service
center in this case.
Reducing tension
1. Place a suitable container underneath to collect the grease.
2. Slowly turn lubricating valve A one revolution anticlockwise to release
the grease.
➥ The grease flows out of the groove of the lubricating valve.
3. Retighten lubricating valve A.
4. In order to check that the tension is correct:
- Lowering the machine to the ground, starting the engine, letting it run
at idling speed without any load and slowly moving the machine
forward and reverse and switching it off again. Raise the machine
again by means of the boom and stabilizer blade.
5. Check the track tension again.
➥ If it is not correct:
6. Adjust again.
Use a suitable container to collect fluids and lubricants as they flow out
and dispose of them in an environmentally friendly manner.
