5.8 TROUBLESHOOTING
A) The engine does not start at all: check what follows:
1) the fuel level reaches at least the half of the fuel
tank;
2) the fuel cap is open (if any);
3) the accelerator is in START position (end of
stroke), the control cable is not released or broken
and the rich mixture control is working («air» -
primer);
4) the fuel reaches the carburetor or the injector.
5) the vent on the fuel cap is not clogged;
6) the filter on the carburetor inlet is clean (if any);
7) the carburetor jet is clean. In order to check it,
unscrew it and if dirty, clean it by means of an air
jet;
8) the spark plug makes sparks (gasoline engines).
In order to carry out this check, disassemble the
plug, connect it again to the current cable, lean the
metallic ground part and pull slowly the rope of the
engine recoil starter, as if you wanted to start it.
If there is no spark between the two electrodes, try
to check the connections between the spark plug
cable and if the current does not arrive yet, replace
the spark plug. If also this gives no results, the
problem concerns the electric system, and at this
point we advice you to contact the closest service
center or a specialized repair shop.
For the engines with electric starter, besides the
above mentioned checks, check that:
1) the battery cables are well connected and oxide
free;
2) the battery is sufficiently charged;
3) some cables did not come out from the starter unit;
4) the battery charger pilot light is on only when the
engine idles and that it is automatically off when
it accelerates.
B) The engine has no power:
1) check if the air filter is clean; in case it is dirty,
remove the dirt by means of a compressed air jet;
2) replace the filter in case it is dirty with oil, above
all during the transportation;
3) enough gas oil (Diesel engine) arrives to the injec-
tor.
C) The machine moves forward with difficulty or the
PTO does not work well:
1) Check the distance between the control screw
and the gear clutch lever (distance between 0.5
and 2 mm); eventually record it as described in
the specific chapter 5.3.1.
2) Check that the accessory is well inserted into the
PTO quick coupling.
3) Make sure that the clutch is not worn or damaged;
ENGLISH
to check this and eventually change the clutch, call
the nearest Service.
D) The speeds or the PTO are engaged with difficulty:
1) Check that the control clutch lever (16, Fig. 1) in
the release position takes the vertical position.
2) To facilitate the insertion of the gears and/or PTO
little and slowly lower the control clutch lever.
