Each time the head is bumped, the line
advance about 1 inch(25.4 mm). For better
effect, tap the head on bear ground or hard
soil. Avoid bumping in thick, tall grass as
the engine may stall by overload.

WARNING
•
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.
