5.1.3 Cleaning
Make sure that the machine is kept as clean as possible. The machine’s service life and its satisfactory operation depend on the care given in cleaning it.
Clean the machine carefully with a clean rag or an air gun, taking care to remove any dirt that may be deposited on it,
especially close to moving parts and the cooling fins on the engine. As a precaution, systematically wear gloves to avoid injuring or burning your hands. Do
not use petrol for cleaning. Only use non-inflammable and non-toxic products that are inoffensive for the user and the equipment.
5.1.4 T
ightening
After a running-in period of about 1 hour’s work, check that all accessible nuts and screws are tight and seated correctly.
Refer to plan 36 000 ME for the tightening torques to be applied on the machine’s silent blocks if ever they need to be replaced.
5.1.5 Removing the engine cover
In order to carry out certain maintenance operations and access certain parts of the engine, engine cover, Item ②, must be
removed and the exhaust deflector must be dismantled by loosening the 2 screws holding it to the exhaust unit.
Do not start the engine when the cover has been removed.
Proceed as follows for removing the engine cover:
➊ Unscrew bolt Item ① (See Fig.1).
➋ Remove engine cover Item ②.
5.1.6 Carburettor
On leaving our works, the carburettor is delivered with the best-possible setting corresponding to the barometric and climatic conditions in our works at the
time.
Besides normal servicing during use, it is recommended that any possible repairs or adjustments to the carburettor are carried out by members of the
GEISMAR sales or repair network. All carburettor adjustments must be made when the engine is hot.
Regularly check the engine’s maximum speed when under load (5,500 rpm) (See §2.3 “Technical characteristics”). A check must be made before the machine
is used for the first time, weather conditions and altitude may considerably modify settings.
Use an electronic rev-counter for this check (Ref. HLN). If the engine speed is higher than 5,500 rpm under load (as shown in §2.3 “Technical
characteristics”), settings must be adjusted.
Rotate the carburettor setting screw very carefully and in small steps, as the slightest adjustment will give rise to a significant change in the way the engine
runs.
Too low or too high speeds on the vibration generating mechanism may cause premature wear on certain parts, or even serious operating incidents.
