GENERAL MAINTENANCE
The walking tractor G131 does not require special maintenance. However, to keep it at its highest
performance the following operations are recommended:
– Check that all screws and nuts are tightened; particularly those fixing the tines, those of the
engine and of the rotary tiller at the flange.
– Lubricate the clutch and throttle wires.
– Lubricate the sliding bearing of the handlebar locking pin.
– Remove any leaves and grass that may have deposited on the engine front grid.
– Often check oil levels and clean the air filter frequently.
– Grease the machine coupling 2 or 3 times a year, by disconnecting the rotary tiller from the
flange.
END OF SEASON MAINTENANCE
Carefully wash the walking tractor, replace the oil in both the engine, the gearbox oil and the rotary
tiller, clean the air filter. Sharpen the hoes and grease them. Replace them if worn. IMPORTANT:
The hoes of Grillo walking tractors are made of a special steel subjected to heat treatments.
Never weld the hoes if broken or cracked, because they could break and be flung away
becoming therefore highly dangerous for people and objects around.
