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 nylon head locks up or
becomes clogged with vegetation—the function will activate
to stop the motor. If this happens, the power lamp will fl ash.
Check the lamp status and take appropriate corrective
action.
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 nylon head, turn off the power
and remove the battery from the tool main unit.

MAINTENANCE AND INSPECTION
CAUTION
Pull out battery before doing any inspection or
maintenance.
1. Checking the condition of the nylon head
The nylon head should be checked regularly. If worn or
broken nylon head can slip or decrease the effi ciency of
the motor and burn it out.
Replace worn nylon head with new ones.
CAUTION
If you use a nylon head of which point is worn or broken,
it will be dangerous. So replace it with a new one.
2. Check the Screws
Loose screws are dangerous. Regularly inspect them
and make sure they are tight.
CAUTION
Using this power tool with loosened screws is extremely
dangerous.
3. Inspection of terminals (tool and battery)
Check to make sure that swarf and dust have not
collected on the terminals.
On occasion check prior, during and after operation.
CAUTION
Remove any swarf or dust which may have collected on
the terminals.
Failure to do so may result in malfunction.
4. Cleaning of the outside
When the grass trimmer is stained, wipe with a soft dry
cloth or a cloth moistened with soapy water. Do not use
chloric solvents, gasoline or paint thinner, as they melt
plastics.
5. Storage
Store grass trimmer in a place in which the temperature
is less than 40°C and out of reach of children.
NOTE
Storing Lithium-ion Batteries
Make sure the lithium-ion batteries have been fully
charged before storing them.
Prolonged storage (3 months or more) of batteries with
a low charge may result in performance deterioration,
signifi cantly reducing battery usage time or rendering
the batteries incapable of holding a charge.
However, signifi cantly reduced battery usage time may
be recovered by repeatedly charging and using the
batteries two to fi ve times.
If the battery usage time is extremely short despite
repeated charging and use, consider the batteries dead
and purchase new batteries.
CAUTION
In the operation and maintenance of power tools, the
safety regulations and standards prescribed in each
country must be observed.
