Translation of the Original Instructions
END OF WORK
Once work is ended, switch the engine off, remove the key (for machines with electric starter), set
the gear lever into neutral and disengage the PTO. When the gear is in idle position (letter F on the
label) it is possible to move the machine manually.
CAUTION : never leave the machine on slopes
with the gear lever in neutral position. If the machine is to be parked on a slope always engage the
1
st
gear. CAUTION: never leave the machine unguarded or in a place where children or
inexperienced people could have easy access to it.
TROUBLESHOOTING
The following is a list of inconveniences which may occur during the use of the walking tractor,
which the operator himself can remedy.
1) if the petrol engine does not start check:
– that the fuel tank is at least half full;
– that the petrol cock is turned on;
– that the choke is engaged (when the engine is cold);
– that fuel is normally going to the carburettor;
– that the vent hole on the fuel tank is not blocked;
– that the mesh filter at the carburettor intake is clean;
– that the carburettor jets are clean. Check by unscrewing them and if dirty, clean them with a jet of
air;
– that spark plug is generating a spark. To check this, remove the spark plug, re-connect it to the
electricity supply wire, rest the metal side on an electrical earth and turn the engine-pulley as if to
start it. If no spark is seen between the electrodes, check the connection of the spark plug cable; if
there is still no current replace the spark plug with a new one. If a spark is still not obtained, the
problem is in the electric system: capacitor, coil, or in some other component. Contact your nearest
service centre or a specialist workshop.
2) if the diesel engine does not start check:
– that the fuel tank vent hole is not blocked;
– that the fuel tank is at least half full.
3) If the engine is on but the machine does not move forward:
– check that the gear is engaged.
– check that the red clutch lever is fully pressed down and that the clutch spring is compressed (fig.
8). Should this not be the case, adjust the screw of the clutch cable (fig. 3A, n. 17).
4) if the petrol engine cannot be switched off:
– check that the throttle lever (fig. 3, n. 24) is in “0” position.
– check that the electric wire to switch off the engine is correctly connected with the throttle lever
and with the connector on the engine.
5) if the diesel engine cannot be switched off:
– check that the lever to switch off the diesel engines located on the left side of the handlebar (fig.
3A, n. 25) is fully pressed down.
– check that the electric wire to switch off is correctly connected to the engine.
IN CASE OF LONG IDLE PERIODS
Should the machine not be used for a long time:
- fully empty the fuel tank.
- thoroughly clean both the engine and the walking tractor. Lubricate the handlebar support.
