order

to avoid the risk of injury, electric

shock and fire

hazards.

Please read and

observe

the

instructions below

before

using the appliance.

t^ l

1.

lZ\

4uo;X short circuits.

Short circuiting

the contacts of

the

charger

or

battery

oresents a risk of

fire.

2.

ol

lhe surrounding

area into

account.

Don't expose the charger to rain and don't

use it in damp

0r

wet

surroundings

or in the vicinity of

flammable liq-

uids

or

gases.

cneck the charger each

time belore use.

Checkthe condition

ofthe charger, supply

cord and

Don't use the charger

if it is found to be damaged,

incom-

plete

or if the controls cannot

be operated c0rrectly.

4. Use

the

Connect the charger

to the mains supply.

-

The mains voltage

must corresp0nd to the infor-

mation

given

on the rating

plate.

lf,

after unplugging and reconnecting

the

charger to the mains

supply,

the

self-test

is

still

not

successful,

please

return

the charger to a Hilti

service centre for reoair.

A]

/'\

Operale

the

charger only at a suitable location.

-

The

location for operation

of

the

charger should

be dry, clean

and cool but not exposed to frost.

-

The

charger

must

be able to

give

off heat during

the charging

procedure.

Accordingly, the ventlla-

tion slots must

always be unobstructed.

Condilioning charge mode

E

NiCd cells are subject to self-discharge. With

older bat-

teries, the rate

of self-discharge of some of the cells may

be higher than that of others. As

conventional chargers

switch

off

when the first

cells

have reached

full charge,

the

other

partly

charged cells do not receive the full

charge. The

user becomes aware of

this

effect in the

form

of

inadequate

battery capacity.

This

effect can be eliminated by applying a conditioning

charge. During this

procedure,

the

charger supplies a

small

current over several

hours,

with

pauses

made in

order

to

avoid overheating the battery. Depending

on

its

condition, the llattery will take 7 to 10

hours t0 reach

full

charge.

The

conditioning charge begins when the

conditioning

mode button is

pressed

before insertion

of

the

battery

and released

approx. 3 seconds after the battery has

been

inserted.

The

yellow

LED lights while the

battery

is being charged in conditioning mode.

The battery

should be charged

in

conditioning mode no

more than

once a month. The conditioning

charge

is,

so to

speak, a

kind

of

"training"

for the battery. Just as

excessive training can be harmful to the human

body,

t00 frequent

use of conditioning charging mode can also

weaken

the battery.

Baltery

(accessory)

f ^ l

/\

Brforr a battery is

used

for the first

time, it must

be charged

for 24

hours

in normal

mode or for 1

0

hours

in conditioning mode in order to

permit

"forming"

of the

battery

cells.

-At

iow

temperatures: Battery

performance

drops at

low temperatures.

Store

batteries

at

r00m tempera-

ture when not in

use.

-At

high

temperatures: Do n0t store

batteries

where

they may be subjected t0 high temperatures

(e.9.

exposed

to

the sun, at a window, behind

a car

wind-

screen or on a radiator).

Never fully discharge

a battery. Change the battery as

s00n

as

its

0erformance

droos. The cells that reach

a

state of total discharge first will

otherwise be damaged

by the

current still being drawn from the other cells.

An

excepti0n

to this is the

BP 6-86 battery for the

TE 6-4

(this

battery is equipped with

an electronic deep

discharge

prevention

device).

Care and

maintenance

Care of

the

charger

The outer casing of the charger is made

f rom impact-

resistant

plastic.

tat tAl

|lAl @l Clean the outside of the charger at regular

intervals

using a slightly

damp cloth. Do not use a spray,

steam

pressure

cleaning equipment or

running water

for cleaning. This may negatively af{ect the electrical

safety of

the

charger.

Do not use cleaning agents which

contain silicone.

t^l

lA

rysvsr ooerate the

tool when the ventilation

slots

are blocked.

ilean

the ventilation slots carefully using

a dry brush.

Do not

permit

foreign

objects

t0 enter the

interior of the charger.

Take care 0f

your

batteries. lf necessary, use a dry cloth

to

clean

the

contacts.

Mainlenance

Do not operate

the

charger

when

parts

are

damaged or when the controls do not function fault-

lessly. When necessary,

your

electric

tool should be

renaired

at a Hilti service centre.
