5.4 EXTRAORDINARY MAINTENANCE
The operations of extraordinary maintenance are not
mentioned in this manual: however, they shall be per-
formed only by the Manufacturer or by skilled per-
sonnel authorized by the Manufacturer himself.
5.5 SETTING AT REST
In case you foresee a long period of inactivity for the
machine, it is necessary:
- To clean thoroughly all dirt on the machine.
- To check the correct tightening of the screws.
- To check and replace, if necessary, the damaged
or worn parts.
- To coat the ruined or abraded parts with an anti-
trust varnish.
- To lubricate/grease all parts subject to wear.
- Completely empty the tank and the carburetor (for
the gasoline engines).
- To cover the machine with a cloth and put it inside,
away from bad weathers, freezing and humidity.
5.6 MACHINE DISMANTLING
In case you decide to dismantle the machine, you shall
separate its components in equal parts which must
be disposed one by one in compliance with the local
regulations concerning waste disposal.
Dispose the exhausted lubricants and the several de-
tergents, according to their different structure.
WARNING
FOR THE DISPOSAL OF THE SEVERAL COMPO-
NENTS, CONTACT EXCLUSIVELY LEGALLY AUTHOR-
IZED COMPANIES THAT MAY ISSUE A REGULAR
RECEIPT OF THE DISPOSAL.
5.7 SPARE PARTS
The spare parts of the engine unit must be directly
requested to the engine manufacturer or its dealer.
In order to request the spare parts of the machine,
contact the local Dealer of the Manufacturer.
We finally remind you that the Manufacturer is al-
ways at your disposal in case you need after-sale
service and/or spare parts.
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;
44
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, un-
screw 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 me-
tallic 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 re-
sults, the problem concerns the electric system,
and at this point we advice you to contact the clos-
est 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 in-
jector.
C) The machine moves forward with difficulty or the
PTO does not work well:
1) Check the clutch levers clearance.
2) Check that the accessory is well inserted into the
PTO quick coupling.
3) Make sure that the clutch is not worn or damaged;
to check this and eventually change the clutch, call
the nearest Service.
D) The speeds or the PTO are engaged with difficulty:
1) Adjust correctly the clutch lever, because it can
have too much clearance and make the clutch work
incorrectly.
