sounds, odor, or vibrations after starting, stop the
engine immediately and inspect it. If the engine
is operated without attending to such problems, an
accident may occur.
WARNING: To avoid accidents, maintain a
distance of more than 15 m (50 ft) between oper-
ators when two or more operators are working
in one area. Be sure that there is someone there
to observe the distance between operators. If a
person or an animal enters the work area, immedi-
ately stop operation.

load or run at a higher speed than required . Doing
so may cause an engine malfunction.
Always hold the machine on your right side and slide it
