1. Prepare a grease pump.
2. Loosen the two screws and rotate the bottom cover
to access the lubrication nipple.
3. Raise the machine with the equipment by activating
the command lever.
WARNING
Do not support the machine with the accessory on-
ly. The command levers may move or hydraulic oil
may spill accidentally and cause the machine to
fall.
When the machine is checked or adjusted by two
people, one of them must commission the machine
according to the signals given by the other person.
Be sure to perform the track tension verification
on a firm and even surface. It is strictly forbidden
to be positioned under the machine for the dura-
tion of the operation.
4. Using the grease pump, inject grease with the grea-
ser so that the play H is between 8 ~ 13 mm.
5. Proceed with the track tensioning.To check that the
tension is correct, put the machine down and move it
gently forwards and backwards.
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 tension is still in-
sufficient, 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.
