Maintenance
Steel track (option)
•Place a measuring rod A across the highest points of the track.
•Adjust the correct track tension if the play between the track roller and the
track is not 20 – 25 mm (0.8 - 1 in).
Setting the tracks
Risk of lubricant escaping under high pressure!
Can cause serious injury or death.
• Do not loosen and unscrew the lubricating valve by more than one turn.
• Only the lubricating valve may be loosened.
• Keep your face away from the lubricating valve connection.
➥ Contact a Wacker Neuson service center if this does not reduce track
tension.
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 dealer in this case.
