6. While holding the unit firmly, pull out the
starter rope quickly until engine fires.
The product is equipped with a centrifugal
clutch mechanism, so the cutting
attachment begins to rotate as soon as the
engine is started by putting the throttle into
the start position. When starting the engine,
place the product onto the ground in a flat
clear area and hold it firmly in place so as
to ensure that neither the cutting part nor
the throttle come into contact with any
obstacle when the engine starts.
Avoid pulling the rope to its end or returning it
by releasing the knob. Such actions can cause
starter failures.
7. Move the choke lever downward to open the
choke. And restart engine.
8. Allow the engine to warm up for a several
minutes before starting operation.
1. When restarting the engine immediately after
stopping it, leave the choke open.
2. Overchoking can make the engine hard to
start due to excess fuel. When the engine
failed to start after several attempts, open
the choke and repeat pulling the rope, or
remove the spark plug and dry it.
