Remove track adjuster cover (1) and the O-ring seal from the track roller frame.
To prevent personal injury, never visually inspect the vent holes or the valves to see if grease or oil is coming out of them. Make sure the vent holes are clean before the tension is released on the track. Watch the front roller frame to see that it moves.

Loosen the track by the following steps:
Turn relief valve (2) counterclockwise by one turn. This adjustment releases grease from the track tension cylinder. If the track does not loosen, proceed to Step 2.b.
Turn relief valve (2) counterclockwise by one turn. This adjustment releases grease from the track tension cylinder. If the track does not loosen, start the machine. Move the machine forward and backward. If grease is not released, proceed to Step 2.c.
Install a piece of round bar stock between the bushing and the sprocket inside the track links. Move the machine to the rear, so the round bar stock pushes the track upward. This movement increases tension on the track. The track tension cylinder moves inward.
