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. Inspecting the carbon brushes (Fig. 42)
The motor employs carbon brushes which are
consumable parts. Since and excessively worn carbon
brush can result in motor trouble, replace the carbon
brush with new ones when it becomes worn to or near
the "wear limit". In addition, always keep carbon brushes
clean and ensure that they slide freely within the brush
holders.
NOTE
When replacing the carbon brush with a new one, be sure
to use the Hitachi Carbon Brush Code No. 999015.
4. Replacing carbon brushes
Take out the carbon brush by fi rst removing the brush cap
and then hooking the protrusion of the carbon brush with
a slotted head screw driver, etc., as shown in Fig. 43.
When installing the carbon brush, choose the direction
so that the nail of the carbon brush (see Fig. 44) agrees
with the contact portion of brush tube. Then push it in with
a fi nger as illustrated in Fig. 45. Lastly, install the brush
cap.
CAUTION
◯ Be absolutely sure to insert the nail of the carbon brush
into the contact portion of brush tube. (You can insert
whichever one of the two nails provided.)
◯ Caution must be exercised since any error in this
operation can result in the deformed nail of the carbon
brush and may cause motor trouble at an early stage.
5. 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.
6. Storage
Store grass trimmer in a place in which the temperature is
less than 40°C and out of reach of children.
NOTE
Make sure that the battery is fully charged when stored
for a long period (3 months or more). The battery with
smaller capacity may not be able to be charged when
used, if stored for a long period.

NOTE
Storing Lithium-ion Batteries
Make sure the lithium-ion batteries have been fully
charged before storing them.
Prolonged storage 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.
7. Service parts list
CAUTION
Repair, modifi cation and inspection of Hitachi Power
Tools must be carried out by a Hitachi Authorized Service
Center.
This Parts List will be helpful if presented with the tool to
the Hitachi Authorized Service Center when requesting
repair or other maintenance.
In the operation and maintenance of power tools, the
safety regulations and standards prescribed in each
country must be observed.
