    ------ WARNING! ------

    Personal injury or death can result from grease and oil coming out of the relief valve.

    Grease and oil are under high pressure coming out of the relief valve and can penetrate the body.

    Do not watch the relief valve to see if grease is escaping. Watch the track or track adjustment cylinder to see if the track is being loosened.

    Make sure the vent holes are clean before the tension is released on the track.


  3. Release the tension on the track assembly. Slowly loosen relief valve (1) for the track adjuster. Do not loosen the relief valve more than one turn.

    Note: If the track assembly does not loosen, rotate the track forward and backward until the track tension is released.
