PLEASE SAVE THESE IMPORTANT SAFETY AND OPERATING INSTRUCTIONS

For correct operation of the equipment, it is important to read and be familiar

with this entire manual before installing and operating the charger.

DO NOT DISCARD THIS MANUAL AFTER READING.

LOOK  FOR  THIS  SYMBOL  TO  POINT  OUT  SAFETY  PRECAUTIONS.    IT  MEANS:

BECOME  ALERT—YOUR  SAFETY  IS  INVOLVED.

IF  YOU  DO  NOT  FOLLOW  THESE

SAFETY INSTRUCTIONS, INJURY OR PROPERTY DAMAGE CAN OCCUR.

Features

Patented electronic circuit monitors battery state of charge and automatically turns charger off when battery is fully charged.

Line voltage compensation produces consistent charger output for AC supply voltage variations of ±10% from nominal.

Reverse polarity protected and no output voltage when disconnected from battery.

Convection cooled design for maximum reliability and minimum maintenance.

IMPORTANT SAFETY INSTRUCTIONS

1.

Before 

using 

battery 

charger, 

read 

all

instructions  and  cautionary  markings  on  battery
charger and battery.

CAUTION:    TO  REDUCE  RISK  OF  INJURY,

CHARGE  ONLY  LEAD-ACID  TYPE  RECHARGE-
ABLE 

BATTERIES. 

 

OTHER 

TYPES 

OF

BATTERIES  MAY  BURST  CAUSING  PERSONAL
INJURY AND DAMAGE.

2.

Keep  dry;  do  not  expose  charger  to  rain  or
snow.  For storage, keep charger in a building.

3.

Use of an attachment not recommended or sold
by  the  battery  charger  manufacturer  may  result
in  a  risk  of  fire,  electric  shock,  or  injury  to
persons.

4.

To  reduce  risk  of  damage  to  electric  plug  and
cord,  pull  by  plug  rather  than  cord  when
disconnecting charger.

5.

Make  sure  cord  is  located  so  that  it  will  not  be
stepped  on,  tripped  over  or  otherwise  subjected
to damage or stress.

6.

An  extension  cord  should  not  be  used  unless
absolutely  necessary.    Use  of  an  improper
