Correcting track tension
Injury hazard due to grease escaping under pressure!
Grease escaping under pressure can penetrate the skin and cause
serious injuries or death.
► Open the lubricating valve only very carefully and do not unscrew it
more than a revolution.
► Wear protective gloves and safety glasses.
► Release grease only as described below.
► Contact a Wacker Neuson service center if this does not reduce track
tension.
Damage to tracks due to overtightening. This causes severe damage to
the hydraulic cylinder and the track.
► Tighten the tracks only up to the mandatory measuring distance.
Tightening the tracks
1. Place the machine on firm, level and horizontal ground.
2. Raise the machine evenly and horizontally by means of the boom and
the 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. Lower the machine to the ground.
7. Check the tension is correct by:
- starting the engine,
- letting it run at idling speed without any load
- slowly moving the machine forward and reverse and switching it off
again.
8. Check the track tension again.
