To adjust belt tension, remove the protective house, loosen the engine fastening screws. Using the
tightening screw on the cutting guide, tighten until an adequate level is achieved (between 8 - 10 mm).
Next, tighten the engine fastening screws and ensure that the pulleys are correctly aligned. Then, tighten the
lock of the tightening screw and assemble the belt guard. The machine is now ready to work again.
When a belt needs replacing, it is best to replace the whole set at a time.

10.2. CLEANING

Cleaning the machine is fundamental for its operational life.
ANY CLEANING OPERATION MUST BE CONDUCTED WITH THE MACHINE STOPPED.
Because of the nature of the work it performs, it is inevitable that particles are thrown onto the machine. The
parts of the machine must be cleaned periodically using a wet cloth. Do not use pressurized water.
Rubble and the material residues from cutting must be removed.
Bear in mind the potential risk posed by materials from the works (concrete, mud, etc.) being thrown onto the
machine. Remove them immediately.
Starting the machine without having every component properly installed and fixed is strictly prohibited.
