extension  cord  could  result  in  a  risk  of  fire  and
electric  shock.    If  an  extension  cord  must  be
used, make sure that:

a.

Pins  on  the  plug  of  the  extension  cord  are
the same number, size, and shape as those
on  the  charger  (refer  to  Grounding
Instructions);

b.

Extension cord is properly wired and in good
electrical condition; and

c.

Wire size is No. 14 AWG or larger.

7.

Make  sure  all  electrical  connectors  are  in  good
working  condition.    DO  NOT  operate  charger
with a worn, cut, or damaged cord or plug.  Use
of a damaged cord or plug may result in a risk of
fire, electric shock, or injury to persons.  Take to
a qualified service agent for repairs.

8.

Do not operate charger if it has received a sharp
blow,  been  dropped,  or  otherwise  damaged  in
any way; take it to a qualified service agent.

9.

Do  not  disassemble  charger;  take  it  to  a
qualified service agent when service or repair is
required.    Incorrect  reassembly  may  result  in  a
risk of electric shock or fire.

10. To reduce risk of electric shock, unplug charger

from  outlet  before  attempting  any  maintenance
or cleaning.  Turning off controls will not reduce
this risk.

11. Provide  adequate  ventilation  for  both  batteries

and  charger.    The  convection  cooled  design
requires  an  unobstructed  flow  of  cooling  air  for
proper  operation.    Keep  all  charger  ventilation
openings  at  least  two  inches  (2")  (5cm)  away
from walls and other objects.

GROUNDING AND AC POWER CORD
CONNECTION INSTRUCTIONS

This charger must be grounded to reduce the risk of
electric shock.  This battery charger is equipped with
an  electric  cord  having  an  equipment-grounding
conductor  and  a  grounding-type  plug.    The  plug
must  be  plugged  into  an  appropriate  outlet  that  is
properly  installed  and  grounded  in  accordance  with
the National Electrical Code and all local codes and
ordinances.

DANGER: NEVER  ALTER  AC  CORD  OR

PLUG  PROVIDED;  IF  IT  WILL  NOT  FIT  OUTLET,
HAVE  PROPER  OUTLET  INSTALLED  BY  A
QUALIFIED 

ELECTRICIAN. 

 

IMPROPER

CONNECTION  CAN  RESULT  IN  A  RISK  OF
ELECTRIC SHOCK.

This  battery  charger  is  equipped  with  a  grounding
plug as illustrated in adjacent Figure A, for use on a
nominal  120  volt,  60  Hertz  circuit.    A  temporary
adapter,  as  illustrated  in  Figures  B  and  C,  may  be
used to connect this plug to a two-pole receptacle as
shown  in  Figure  B  if  a  properly  grounded  outlet  is
not  available.    The  temporary  adapter  should  be
used  only  until  a  properly  grounded  outlet  can  be
installed  by  a  qualified  electrician.    The  green-
colored rigid ear extending from the adapter must be
connected  to  a  permanent  ground  such  as  a
properly grounded outlet box.

DANGER: BEFORE  USING  ADAPTER  AS

ILLUSTRATED,  BE  CERTAIN  THE  CENTER
SCREW OF OUTLET PLATE IS GROUNDED.  THE
GREEN-COLORED 

RIGID 

EAR 

OR
