When

 

the

 

pilot

 

lamp

 fl 

ickers

 

in

 

red

 

(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

 

your

 

authorized

 

Service

 

Center.

PRIOR TO OPERATION

1.  Preparing and checking the work environment

 

Make

 

sure

 

that

 

the

 

work

 

site

 

meets

 

all

 

the

 

conditions

 

laid

 

forth

 

in

 

the

 

precautions.

2.  Checking the battery

 

Make

 

sure

 

that

 

the

 

battery

 

is

 

installed

 fi 

rmly.

 

If

 

it

 

is

 

at

 

all

 

loose

 

it

 

could

 

come

 

o

ff

  

and

 

cause

 

an

 

accident.

3.  Selecting the socket matched to the bolt 

 

Be

 

sure

 

to

 

use

 

a

 

socket

 

which

 

is

 

matched

 

to

 

the

 

bolt

 

to

 

be

 

tightened.

 

Using

 

an

 

improper

 

socket

 

will

 

not

 

only

 

result

 

in

 

insu

ffi

  

cient

 

tightening

 

but

 

also

 

in

 

damage

 

to

 

the

 

socket

 

or

 

nut.

 

A

 

worn

 

or

 

deformed

 

hex.

 

or

 

square-holed

 

socket

 

will

 

not

 

give

 

an

 

adequate

 

tightness

 

for

 fi 

tting

 

to

 

the

 

nut

 

or

 

anvil,

 

consequently

 

resulting

 

in

 

loss

 

of

 

tightening

 

torque.

 

Pay

 

attention

 

to

 

wear

If

 

your

 

eye

 

is

 

continuously

 

exposed

 

to

 

the

 

light,

 

your

 

eye

 

will

 

be

minutes.

4.  Tightening and loosening bolts

 

A

 

hex.

 

socket

 

matching

 

the

 

bolt

 

or

 

nut

 

must

 fi 

rst

 

be

 

selected.

 

Then

 

mount

 

the

 

socket

 

on

 

the

 

anvil,

 

and

 

grip

 

the

 

nut

 

to

 

be

 

tightened

 

with

 

the

 

hex.

 

socket.

 

Holding

 

the

 

wrench

 

in

 

line

 

with

 

the

 

bolt,

 

press

 

the

 

power

 

switch

 

to

 

impact

 

the

 

nut

 

for

 

several

 

seconds.

 

If

 

the

 

nut

 

is

 

only

 

loosely

 fi 

tted

 

to

 

the

 

bolt,

 

the

 

bolt

 

may

 

turn

 

with

 

the

 

nut,

 

therefore

 

mistaking

 

proper

 

tightening.

 

In

 

this

 

case,

 

stop

 

impact

 

on

 

the

 

nut

 

and

 

hold

 

the

 

bolt

 

head

 

with

 

a

 

wrench

 

before

 

restarting

 

impact,

 

or

 

manually

 

tighten

 

the

 

bolt

 

and

 

nut

 

to

 

prevent

 

them

 

slipping.

OPERATIONAL CAUTIONS

1.  Resting the unit after continuous work

 

After

 

use

 

for

 

continuous

 

bolt-tightening

 

work,

 

rest

 

the

 

unit

 

for

 

15

 

minutes

 

or

 

so

 

when

 

replacing

 

the

 

battery.

 

The

 

temperature

 

of

 

the

 

motor,

 

switch,

 

etc.,

 

will

 

rise

 

if

 

the

 

work

 

is

 

started

 

again

 

immediately

 

after

 

battery

 

replacement,

 

eventually

 

resulting

 

in

 

burnout.

NOTE:

 

Do

 

not

 

touch

 

the

 

metal

 

parts,

 

as

 

it

 

gets

 

very

 

hot

 

during

 

continuous

 

work.

2.  Work at a tightening torque suitable for the bolt 

under impact

 

The

 

optimum

 

tightening

 

torque

 

for

 

nuts

 

or

 

bolts

 

di

ff

 

ers

 

with

 

material

 

and

 

size

 

of

 

the

 

nuts

 

or

 

bolts.

 

An

 

excessively

 

large

 

tightening

 

torque

 

for

 

a

 

small

 

bolt

 

may

 

stretch

 

or

 

break

 

the

 

bolt.

 

The

 

tightening

 

torque

 

increases

 

in

 

proportion

 

to

 

the

 

operation

 

time.

 

Use

 

the

 

correct

 

operating

 

time

 

for

 

the

 

bolt.
