For proper screw tightening, use an adequate torque wrench and the values listed in the tables below:
Thread
M6
M8
M10
M12
M14
M16
These are guiding values, and are based on average conditions of steel-to-steel friction.

5/16 23.9
3/8 41.5
1/2 101.0

These are guiding values, and are based on average conditions of steel-to-steel friction.
Avoid using fuel that has been stored for more
 
than seven days as it causes malfunctioning and
decreases the useful life of the engine.
Fill the tank carefully not to spill the fuel.
 
Use common gasoline, diesel or biodiesel only
 
(do not use with additives).
Note the capacity of the fuel tank, and the quantity
 
and type of oil of the crankcase (see "Technical
Specifications").
