Maintenance And Inspection - Hitachi UC 10SFL Handling Instructions Manual

English
APPLICATION
For charging the HITACHI BATTERY BCL1015.
CHARGING
Before using the power tool, charge the battery as
follows.
1. Connect the charger power cord to the receptacle
2. Insert the battery in the charger
Position the battery so that the nameplate faces
toward the nameplate of the charger and press in
the battery until it comes into contact with the
bottom plate (See Fig. 1).
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.
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 first,
then start charging.
Regarding recharging time
Table 1 shows the recharging time required
according to the type of battery.

NOTE: The recharging time may vary according to the
ambient temperature.
3. Disconnect the charger's power cord from the
receptacle
4. Hold the charger firmly 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 first
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.

40 min.
(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.
2. Cleaning of the charger
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.
3. Store idle charger
When not in use, the charger should be stored in
dry, high or locked-up place — out of reach of
children.
4. Service parts list
CAUTION
Repair, modification 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.
MODIFICATIONS
Hitachi Power Tools are constantly being improved
and modified to incorporate the latest technological
advancements.
Accordingly, some parts may be changed without
prior notice.
NOTE
Due to HITACHI's continuing program of research and
