3. Check the tension. The play H between the external
rolling surface of the second track roller on the tightener
rooler and the internal surface of the track must be 8 ~
13 mm.

b = Track roller
c = Track
• If the tension is incorrect, follow the procedures given in the following chapters to increase
or release the track tension.
IMPORTANT
Perform a task with a relaxed track link may derail the track or cause premature wear of
the undercarriage.

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, adjust 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 insufficient, 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.
