6. Operation
• Do not start the engine with the throttle
lever kept pulled because the blade will
immediately begin to move upon starting
the engine. When starting the engine, place
the machine on a flat and firm place, and
keep all objects away from the blade.
• When starting the engine, keep all objects
away from the machine so that the blade
does not touch the ground.
• If the blade continues to rotate even after
the throttle lever is returned to the idling
position, stop the engine and check the
idling adjustment screw of the throttle wire
and the carburetor.
• When the engine has started, make sure
that the blade does not move. If the blade
continues to move, stop the engine, and
check the idling adjustment screw of the
throttle wire and the carburetor.
• While using the machine, hold the grips of
the machine with both hands, and keep
your eyes on the blade.
• Do not touch the metal part of the engine
body and the muffler while using the
machine or immediately after stopping
using it, otherwise you might suffer burns.
• Do not touch the spark plug or plug cord
while using the machine, otherwise you
might suffer an electric shock.
If you repeat the starting operation with the choke
closed, the electrode of the spark plug may become
wet and the engine might not start. If this happens,
open the choke, set the throttle lever to the almost
fully-open position and pull out the starter rope
repeatedly, or try the starting operation again after
removing the spark plug and drying the electrode.
IMPORTANT
■ STARTING THE ENGINE
• Before starting the engine after filling with
fuel, move the machine at least 3 m away
from where it was refueled.
Starting the engine where the machine was
refueled might cause a fire.
• Do not start the engine indoors or in any
place which is not well ventilated.
Otherwise, you might suffer carbon
monoxide poisoning which could injure
you.
• Keep the throttle lever set always to the
idling position when starting or stopping
the engine, or moving the machine. If the
throttle lever is set to any position other
than the idling position, the blade will begin
to rotate, causing danger.
• The engine might start after a delay. Hold
the unit until it starts.
• Before starting the engine, check the entire
unit for troubles such as looseness in
installing the handle, malfunctioning of the
throttle lever, looseness in installing the
blade, and fuel leaks.
• When starting the engine, place the
machine on the ground and hold it securely.
Since the blade might touch the ground or
object near the machine, do not start the
engine while holding up the machine with
one hand.
