Personal injury or death can result from grease under pressure.Grease coming out of the relief valve under pressure can penetrate the body causing injury or death.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.Loosen the relief valve one turn only.If track does not loosen, close the relief valve and contact your Caterpillar dealer.
Keeping the track properly adjusted will increase the service life of the track and drive components.

The sag is measured from the highest point of the track grouser to the bottom of the edge. A track that is properly adjusted will have a slack of 40 to 55 mm (1 5/8 to 2 1/8 inch).Tightening The Track
