21
- At cold starting, especially in winter time, do not increase the engine speed but
first let the engine running in idle speed to warm up.
- Do not leave the machine unattended.
At the first start there is much more air in the intake manifold and on this account
the engine may not roar to life immediately when turning the switch key for the
first time. Do not crank the engine for a longer time than 10 sec. Keep an interval
between two starts (standstill) 30 sec. at least.
Note! If the choke is opened for a longer time after start then you may flood the
carburettor and the engine stops. Too much fuel in the firing chamber may increase
engine wear. Let the choke opened only for warming the engine up at idling. Do
not use the choke while working.
Putting out of Operation
- Having finished working reduce the engine speed by the accelerator lever and
wait for real speed decrease (about one minute idling).
- Turn the switch key in the STOP position.
Never forget that the rotor wheel is running out .
