case to replace the knives in the same hole where
they were before being dismantled
DANGER
When for some reason you have to replace a single
knife, you must replace all the other kinves to pre-
vent that the rotating assembly causes imbalances
and strong vibrations resulting in serious dysfun-
ction of the machine.
5.4 EXTRAORDINARY MAINTENANCE
The operations of extraordinary maintenance are
not mentioned in this manual: however, they shall
be performed only by the Manufacturer or by skilled
personnel 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 antitrust
varnish.
- To lubricate/grease all parts subject to wear.
- 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
detergents, 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 always
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 fol-
lows:
1) the fuel level reaches at least the half of the fuel
tank;
2) that the fuel valve is open and that the kill switch
is in the "ON" (if it is present in the engine);
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) that the electrical cable placed in the accelerator
to shut off the motor is not grounded, even when
the lever is in position;
5) the fuel reaches the carburetor or the injector;
6) the vent on the fuel cap is not clogged;
7) the filter on the carburetor inlet is clean (if any);
8) the carburetor jet is clean. In order to check it,
unscrew it and if dirty, clean it by means of an air
jet;
9) 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.
B) The engine has no power:
1) check that the air filter is clean; possibly remo
-
ve the dirt using compressed air;
2) replace the filter if it is soiled with oil, espe
-
cially during transport.
3) replace the spark plug.
C) The machine struggles to advance forward or in
reverse:
1) increase the load on the forward or reverse
gear clutch using the register placed in front of
the control lever (unscrew it a few turns)
