Decrease Track Tension
WARNING!
• The track tension grease fitting is under extreme pressure. Grease can exit the grease valve
at high pressure and cause serious injury.
• Wear safety goggles, gloves, and other personal protective equipment (PPE) to prevent
serious injury.
• Do not stand directly in front of the track tension grease fitting valve when loosening the
valve.
Failure to follow these warnings could result in death or serious injury.
1. Make sure there is no gravel or mud between the sprocket and the track shoe before releasing track tension.
2. Do not loosen the grease fitting (1).
3. Position yourself off to the side, not in front of the
grease valve (2).
4. Using the proper tools, slowly loosen the grease valve
(2) counterclockwise in 90° increments (1/4 turn) to
decrease track tension.
NOTE: The grease will come out from behind the
grease valve.
5. Move the machine back and forth for a short distance if
the grease does not come out smoothly.
6. Check track tension. When it is correct, turn the grease
valve (2) clockwise until it is tight.
7. Move the machine forward at low idle speed for a distance equivalent to the length of an unfolded track.
8. Stop the machine.
9. Check the track for proper tension. Adjust track tension as needed.
