■ HOW TO USE
• This machine is designed so as to
cut twigs upto 8 mm (0.3 inches)
thick. Cutting too thick twigs or
metal wires can not only break the
blade teeth but also give damage to
the drive mechanism.
• When trimming leaves and thin twigs,
guide the blades as drawing a half
circle on the surface, and you will get a
better finish.
• Running the engine at high speed with
the blades Jammed up can shorten the
life of clutch parts. When the blades
have been jammed by thick twigs, stop
operation at once and draw your unit
off the objects after stopping the
engine. When clipping comparatively
thick twigs, move your unit slowly back
and forth like a saw, and they can be
cut to a fine finish.
• When a new unit is first operated, in the
first few minutes grease may come out
of the gear case. But, since this is
