PLEASE SAVE THIS OWNERS MANUAL AND READ BEFORE EACH USE. 

This manual will explain how to use the charger safely and effectively. Please read and follow these instructions and 
precautions carefully. 

1. IMPORTANT SAFETY INSTRUCTIONS 

– SAVE THESE INSTRUCTIONS

1.1 SAVE THESE INSTRUCTIONS

 

– This manual contains important safety and operating instructions.

1.2

 Keep out of reach of children.

1.3

 Do not expose the charger to rain or snow.

1.4

 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.

1.5

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

charger.

1.6

 An extension cord should not be used unless absolutely necessary. Use of improper extension cord could result in

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

• The pins on plug of extension cord are the same number, size and shape as those of plug on charger.
• The extension cord is properly wired and in good electrical condition.
• The wire size is large enough for AC ampere rating of charger as specified in section 8.

1.7

 Do not operate charger with damaged cord or plug 

– replace the cord or plug immediately. 

1.8

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

qualified serviceperson. 

1.9

 Do not disassemble charger; take it to a qualified serviceman when service or repair is required. Incorrect 

reassembly may result in a risk of electric shock or fire. 

1.10

 To reduce risk of electric shock, unplug charger from outlet before attempting any maintenance or cleaning. 

Turning off controls will not reduce this risk. 

1.11

 WARNING: RISK OF EXPLOSIVE GASES. 

a.

WORKING IN VICINITY OF A LEAD-ACID BATTERY IS DANGEROUS. BATTERIES GENERATE

EXPLOSIVE GASES DURING NORMAL BATTERY OPERATION. FOR THIS REASON, IT IS OF UTMOST
IMPORTANCE THAT YOU FOLLOW THE INSTRUCTIONS EACH TIME YOU USE THE CHARGER.

b.

To reduce risk of battery explosion, follow these instructions and those published by battery manufacturer

and manufacturer of any equipment you intend to use in vicinity of battery. Review cautionary markings on
these products and on engine.

2. PERSONAL SAFETY PRECAUTIONS
2.1

 Consider having someone close enough by to come to your aid when you work near a lead-acid battery.

2.2

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

2.3

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

2.4

 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.

2.5

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

2.6

 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.

2.7

 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.

2.8

 Use the charger for charging only 6V or 12V LEAD-ACID (STD, AGM, Gel or deep-cycle) rechargeable batteries. It

is not intended to supply power to a low voltage electrical system other than in a starter-motor 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.

2.9

 NEVER charge a frozen battery.
