Setting the tracks
Danger!
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.
Caution!
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 moving the machine forward and reverse 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 dealer in this case
Reducing 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 moving the machine forward and reverse and switching it off again
☞Check the tension of the tracks again
➥If it is not correct:
