TROUBLESHOOTING
The following is a list of inconveniences which may occur during the use of the tracked carrier,
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 diesel engine cannot be switched off:
– check that the OFF button located on the right side of the handlebar (fig. 23, no. 1) 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 tracked carrier.
- dismount the battery, store it in a dry environment and charge it at least once a month.
