CLEANING
Carefully clean the machine with water after each cut; remove the grass debris and mud accumulated
inside the chassis to avoid their drying and thus making the next start-up difficult.
The paintwork on the inside of the chassis may peel off in time due to the abrasive action of the cut grass;
in this case, intervene promptly by touching up the paintwork using a rustproof paint to prevent the
formation of rust that would lead to corrosion of the metal.
Remove the transmission casing by removing the screws and clean around the transmission and drive
belts with a brush or compressed air once or twice a year.
Once every season, the drive wheels should be cleaned internally. Remove both wheels. Clean the gear
wheel and the wheel gear rim of grass and dirt using a brush or compressed air.
CHANGING BLADES
Empty the oil tank before removing the blade.
To replace the blade, undo the screw.
Reinstall as illustrated. Tighten the screw properly. Tightening torque 45 Nm.
When replacing the blade, the blade screw should also be replaced.
ENGINE MANUAL
You should refer to your engine manual for instructions on changing the engine oil, air filter and draining
the fuel tank and carburettor.
Warning: Avoid skin contact with used engine oil. Wash your skin with soap and water after changing the
oil.
Caution: Used oil is a hazardous waste product. It is recommended that used oil is taken to your local
recycling centre in a properly sealed container. Do not discard with household waste.
Spark Plug
Once the engine has cooled, remove the spark plug and clean the plug with a wire brush. Using a feeler
gauge, set the gap to 0.75 mm (0.030"). Refit the spark plug taking care not to overtighten it.
