10. Maintenance
Changing the transmission chains
If there is the need to repair the transmissions, proceed as follows:
1. Support the equipment using the jacks (A);
2. Totally retreat the hydraulic cylinder to lift the tire from the soil;
3. Release the protection covers;
4. It is not necessary to release all the sprocket set, just release the chain tighteners (B).
Right after, remove the chain that is in need of a repair.
5. After repairing or replacing the chain, return it to its original position and adjust the
tighteners until the chain is totally stretched out.
