Maintenance
Adjusting track tension
The lubricating valve can be squeezed out due to the high grease pressure in
the hydraulic cylinder.
Injury hazard!
☞ Do not loosen and unscrew the lubricating valve by more than one turn.
☞ Loosen no other component except the lubricating valve.
☞ Keep your face away from the lubricating valve connection.
➥ Contact your Neuson dealer if this does not reduce the tension of the
rubber sliding block.
Excessive tension of the tracks causes serious damage to the cylinder and the
track.
☞ Tighten the tracks only up to the prescribed measuring distance!
Tightening the tracks
☞ Inject grease with the pump through lubricating valve A
☞ Check the tension is correct by starting the engine, letting it run at idling speed and
slowly performing forward and reverse machine travel and switching it off again
☞ Check the tension of the tracks again
➥ If it is not correct:
☞ Adjust again
☞ Should the track still be slack after injecting more grease, replace the track or the seal
in the cylinder. Contact a Wacker Neuson service center in this case
Reducing track tension
• Draining grease in a way different from the one described below is very dangerous.
Also bear in mind the safety instructions on this page
☞ Slowly open the lubricating valve A by 1 turn to allow the grease to flow out.
☞ Place a suitable container underneath to collect the grease
➥ The grease flows out of the groove of the lubricating valve
☞ Retighten lubricating valve A
☞ Check the tension is correct by starting the engine, letting it run at idling speed and
slowly performing forward and reverse machine travel and switching it off again
☞ Check the tension of the tracks again
➥ If it is not correct:
☞ Adjust again
Use a suitable container to collect the grease as it flows out and dispose of it in an
environmentally friendly manner.
