The

temperatures

for

rechargeable

batteries

are

as

shown

in

Table 2

,

and

batteries

that

have

become

hot

should

be

cooled

for

a

while

before

being

recharged.

4. Disconnect the charger’s power cord from the

receptacle

5. Hold the charger

NOTE

After

properly.

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

○

When

the

battery

charger

has

been

continuously

used,

the

battery

charger

will

be

heated,

thus

constituting

the

cause

of

the

failures.

Once

the

charging

has

been

completed,

give

15

minutes

rest

until

the

next

charging.

○

If

the

battery

is

recharged

when

it

is

warm

due

to

battery

use

or

exposure

to

sunlight,

the

pilot

lamp

blinks.

The

battery

will

not

be

recharged.

In

such

a

case,

let

the

battery

cool

before

charging.

○

When

the

pilot

lamp

fl

ickers

(at

0.2-second

intervals),

check

for

and

take

out

any

foreign

objects

in

the

charger’s

battery

installation

hole.

If

there

are

no

foreign

objects,

it

is

probable

that

the

battery

or

charger

is

malfunctioning.

Take

it

to

Hitachi

Authorized

Service

Centers.
