USE  IN  VICINITY  OF  BATTERY.    REVIEW
CAUTIONARY 

MARKINGS 

ON 

THESE

PRODUCTS AND ON ENGINE.

1.

Someone  should  be  within  range  of  your  voice
or  close  enough  to  come  to  your  aid  when  you
work near a lead-acid battery.

2.

Wear  complete  eye  protection  and  clothing
protection.    Avoid  touching  eyes  while  working
near battery.

3.

Have  plenty  of  fresh  water  and  soap  nearby  in
case  battery  acid  contacts  skin,  clothing,  or
eyes.

4.

If  battery  acid  contacts  skin  or  clothing,  wash
immediately with soap and water.  If acid enters
eye,  immediately  flood  eye  with  running  cold
water  for  at  least  10  minutes  and  get  medical
attention immediately.

5.

NEVER  smoke  or  allow  a  spark  or  flame  in
vicinity of battery or engine.

6.

Be  extra  cautious  to  reduce  risk  of  dropping  a
metal  tool  onto  battery.    It  might  spark  or  short-
circuit  battery  or  other  electrical  part  that  may
cause explosion.

7.

Remove  personal  metal  items  such  as  rings,
bracelets,  necklaces,  and  watches  when
working  with  a  lead-acid  battery.    A  lead-acid
battery  can  produce  a  short-circuit  current  high
enough  to  weld  a  ring  or  the  like  to  metal
causing a severe burn.

8.

Use  charger  for  charging  a  LEAD-ACID  battery
only.  It is not intended to supply power to a low
voltage  electrical  system  other  than  an
automotive  application.    Do  not  use  battery
charger  for  charging  dry-cell  batteries  that  are
commonly  used  with  home  appliances.    These
batteries may burst and cause injury to persons
and damage to property.

9.

NEVER charge a frozen battery.

CAUTION: 

 

DO 

NOT 

OPERATE 

THE

CHARGER  IF  IT  IS  DAMAGED  OR  APPEARS  TO
BE  MALFUNCTIONING.    PERSONAL  INJURY  OR
DAMAGE 

TO 

THE 

CHARGER 

AND/OR

BATTERIES MAY RESULT.

PREPARING TO CHARGE

1.

If  necessary  to  remove  battery  from  vehicle  to
charge,  always  remove  grounded  terminal  from
battery  first.    Make  sure  all  accessories  in  the
vehicle are off, so as not to cause an arc.

2.

Be  sure  area  around  battery  is  well  ventilated
while  battery  is  being  charged.

Gas  can  be

forcefully  blown  away  by  using  a  piece  of
cardboard  or  other  non-metallic  material  as  a
fan.

3.

Clean  battery  terminals.    Be  careful  to  keep
corrosion from coming in contact with eyes.

4.

Add  distilled  water  in  each  cell  until  battery
reaches level specified by battery manufacturer.
This  helps  purge  excessive  gas  from  cells.    Do
not  overfill.    For  a  battery  without  cell  caps,
carefully 

follow 

manufacturer's 

recharging

instructions.

5.

Study 

all 

battery 

manufacturer's 

specific

precautions  such  as  removing  or  not  removing
cell  caps  while  charging  and  recommended
rates of charge.

6.

Determine  voltage  of  battery  by  referring  to  car
owner's  manual  and  make  sure  charger  output
voltage is the same as battery voltage.

CHARGER LOCATION

1.

Locate  charger  as  far  away  from  battery  as  DC
cables permit.

2.

Never place charger directly above battery being
charged;  gases  from  battery  will  corrode  and
damage charger.

3.

Never allow battery acid to drip on charger when
reading gravity or filling battery.

4.

Do  not  operate  charger  in  a  closed-in  area  or
restrict ventilation in any way.

5.

Do not set a battery on top of charger.

DC CONNECTION PRECAUTIONS

1.

Connect  and  disconnect  DC  output  clips  only
after  setting  all  charger  switches  to  "OFF"
position  and  removing  AC  cord  from  electric
outlet.  Never allow clips to touch each other.

2.

Attach  clips  to  battery  posts  and  twist  or  rock
back  and  forth  several  times  to  make  a  good
connection.    This  tends  to  keep  clips  from
slipping  off  terminals  and  helps  reduce  risk  of
sparking.

NORMAL OPERATING INSTRUCTIONS

1.

With  AC  supply  cord  disconnected  from  outlet
and power switch in "OFF" position, connect DC
output  clips  to  battery  as  described  in  (a)  or  (b)
below:

a.

FOLLOW THESE STEPS FOR A BATTERY
INSTALLED IN A VEHICLE.  POSITION AC
AND  DC  CORDS  TO  REDUCE  RISK  OF
DAMAGE  BY  HOOD,  DOOR,  OR  MOVING
ENGINE  PART.    STAY  CLEAR  OF  FAN
BLADES,  BELTS,  PULLEYS,  AND  OTHER
PARTS  THAT  CAN  CAUSE  INJURY  TO
PERSONS.
