After about 10 hours work, you could probably
face the possibility to adjust the scything blade . In case you need to unscrew the lock-nut (4) and adjust the set-screws (3) to eliminate the over-
clearance between upper / lower teeth.

that the blades can freely turn. Unscrew the screws (1) and take the driving bar plate out (2) . Loosen the plastic-strip (3) , the set-screw (4) and take
the blade out. In case of too much wear , it is necessary to change the plate as well (2) and the spacer-lock (5). To re-assemble the blade , please

ENGINE SERVICING ( please read the specific part). The motormower is delivered equipped with a 4 stroke engine , NO OIL is included. Please fill
the tank in up to the shown level ( capacity about 0,500 kg.) . Referring to the oil/viscosity type, please follow the engine producer instructions.
SCYTHING BAR SERVICING : the motormower is undoubtly one of the most used agricultural equipment and need a good and frequent servicing.
We recommend you to clean very deeply after every use. If the machine is not used for long periods it is ESSENTIAL to protect the blade and the
bar using some anticorrosive and antioxidant materials. The presence of impurities or foreign bodies on the meadow, damages the teeth sharpening
of the scything bar. It is useful to sharpen the blade and check the teeth integrity every 10 hours use, Only if you keep a good sharpening teeth level
you can obtain the best grass cut. Furthermore it is good to perform a periodical control and a possible setting up of the “ clearance” of the blade in
the sliding supports.
