15 m (50 ft) of the person using
the product should be considered
a hazardous area into which no

as to maintain a distance between
each person sufficient to ensure
safety.
2. Check the condition of working
area to avoid any accident by hitting hidden obstacles such as
stumps, stones, cans, or broken

part nor the throttle come into
contact with any obstacle when
the engine starts.

high-speed position when starting
the engine.
3. After starting the engine, check
to make sure that the cutting attachment stops rotating when the
