○ Release the lever when you finish cutting and stop the
motor.
○ Take a posture that makes it easy to move.
[Using the semi-auto nylon head]
–
Do not swing the pipe, but use the hips to move the
nylon head horizontally from left to right in an arc while
going forward and use the right side of the nylon head
for cutting grass. (Fig. 20)
[Using the blade]
–
Cut grass from right to left, using the left side of the
blade to cut. (Fig. 21)
–
Slightly tilting the blade to the left while cutting will pile
the cut grass to the left, making collection easy.
WARNING
○ Blade thrust may occur when the spinning blade
contacts a solid object in the critical area.
A dangerous reaction may occur causing the entire unit
and operator to be thrust violently. This reaction is
called blade thrust. As a result, the operator may lose
control of the unit which may cause serious or fatal
injury. Blade thrust is more likely to occur in areas
where it is difficult to see the material to be cut.
○ If cutting attachment should strike against stones or
other debris, stop the engine and make sure that the
attachment and related parts are undamaged.
NOTE
Excessively increasing rotation speed may cause
increased blade wear, vibration and noise. It will also
wear out the battery faster.
6. Carrying the tool
CAUTION
○ Remove the storage battery. (Fig. 5)
○ Carry the tool holding with hands.
○ If the blade is installed, attach the included blade cover.
OPERATIONAL CAUTIONS
This tool incorporates a function to safeguard the electronic
components that control the main unit. If an overload
occurs during mowing—for example, if the cutting
attachment locks up or becomes clogged with vegetation—
the function will activate to stop the motor. If this happens,
the power switch (47 in Fig. 22) will flash.
Check the signal status and take appropriate corrective
action. (Table 3)
You can resume use after taking the following corrective
action. Take steps to reduce the load imposed on the motor
—for example, by reducing the cutting depth. Before
clearing vegetation from the cutting attachment, turn off the
power and remove the battery from the tool main unit.

recommended by the manufacturer.
Improper maintenance could result in serious machine
damage or in serious personal injury.
The cutting attachment should be checked regularly. If
worn or broken cutting attachment can slip or decrease
the efficiency of the motor and burn it out.
Replace worn cutting attachment with new ones.
If you use a cutting attachment of which point is worn or
broken, it will be dangerous. So replace it with a new
one.
Regularly inspect all mounting screws and ensure that
they are properly tightened. Should any of the screws
be loose, retighten them immediately. Failure to do so
could result in serious hazard.
The motor unit winding is the very "heart" of the power
tool. Exercise due care to ensure the winding does not
become damaged and/or wet with oil or water.
Check to make sure that swarf and dust have not
collected on the terminals.
On occasion check prior, during and after operation.
Remove any swarf or dust which may have collected on
the terminals.
Failure to do so may result in malfunction.
When the power tool is stained, wipe with a soft dry
cloth or a cloth moistened with soapy water. Do not use
chloric solvents, gasoline or paint thinner, for they melt
plastics.
Check gear case or angle gear for grease level about
every 50 hours of operation by removing the grease
filler plug on the side of gear case.
If no grease can be seen in the screw hole on the sides
of the gears, fill the gear case up to 3/4 full with quality
lithium based multipurpose grease (sold separately).
