with safety lever (3).
· To start the engine switch (2) must be set to "1".
· If you want to work with the engine at fixed
speed, press safety lever (3) and move lever
(4) towards the "+" mark until obtaining the
required engine rpm. To disable the fixed
speed setting, return the lever to the "-"
position.
· To stop the engine, set switch (2) to "0".
Observing the Fig,13B:
The switch (5) activate or block the automatic
opening of the liquid tap included in the handle.
· When the switch is in low position, the opening
of the tap is automatic while accelerating. With
the throttle at the idle, the tap remains closed.

always open whatever it is the position of the
throttle. To slide the switch (5) upward, it is
necessary to press simultaneously the throttle
