English
Inserting the battery will turn on the charger (the pilot
lamp lights up).
CAUTION
If the pilot lamp does not light up, pull out the power
cord from the receptacle and check the battery
mounting condition.
The pilot lamp goes off to indicate that the battery is
fully charged.

receptacle
4. Hold the charger fi rmly and pull out the battery
NOTE
Be sure to pull out the battery from the charger after
use, and then keep it.
Regarding electric discharge in case of new
batteries, etc.
As the internal chemical substance of new batteries
and batteries that have not been used for an extended
period is not activated, the electric discharge might be
low when using them the fi rst and second time. This is
a temporary phenomenon, and normal time required
for recharging will be restored by recharging the
batteries 2-3 times.
How to make the batteries perform longer.
(1) Recharge the batteries before they become completely
exhausted.
When you feel that the power of the tool becomes
weaker, stop using the tool and recharge its battery.
If you continue to use the tool and exhaust the electric
current, the battery may be damaged and its life will
become shorter.
(2) Avoid recharging at high temperatures.
A rechargeable battery will be hot immediately after
use. If such a battery is recharged immediately after
use, its internal chemical substance will deteriorate,
and the battery life will be shortened. Leave the battery
and recharge it after it has cooled for a while.

MAINTENANCE AND INSPECTION

1. Inspecting the mounting screws
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.

CAUTION
If the battery is heated due to direct sunlight, etc.,
just after operation, the charger pilot lamp may not
light. At that time cool the battery fi rst, then start
charging.

When the charger 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.
When not in use, the charger should be stored in dry,
high or locked-up place — out of reach of children.
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.
Hitachi Power Tools are constantly being improved
and modifi ed to incorporate the latest technological
advancements.
Accordingly, some parts may be changed without prior
notice.
