Maintenance And Inspection - Hitachi UC 18YGH Bedienungsanleitung

4. Disconnect the charger's power cord from the
receptacle.
5. 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.
(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.
CAUTION
If the battery is charged while it is heated because
it has been left for a long time in a location subject
to direct sunlight or because the battery has just
been used, the pilot lamp of the charger lights for
1 second, does not light for 0.5 seconds (off for
0.5 seconds). In such a case, first let the battery
cool, then start charging.
Since the built-in micro computer takes about 3
seconds to confirm that the battery being charged
with UC18YGH is taken out, wait for a minimum
of 3 seconds before reinserting it to continue
charging. If the battery is reinserted within 3 seconds,
the battery may not be properly charged.

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.
