6.5.4 Increasing the tension
1. Prepare a grease pump.
2. Loosen the two screws and rotate the bottom cover
to access the lubrication nipple.
a = Cover
b = Track roller
c = Track
3. Raise the machine with the equipment by activat-
ing the command lever.
4. Using the grease pump, inject grease with the
greaser so that the play H is between 20 ~ 25 mm.
1 = Greaser
b = Track roller
c = Track
5. Proceed with the track tensioning. To check that the
tension is correct, put the machine down and move it
gently forwards and back.
6. Check the tension again. If it is still not correct, ad-
just it again.
7. Re-install the cover.
• The tension may be adjusted until the distance A is reduced to 0. If the voltage is still insuf-
ficient, the track must be replaced due to excessive wear. Contact your dealer for repair.
• If the tension is weak, even after grease is injected, the track must be replaced or a system
tension check must be performed. Contact your dealer.
