IMPORTANT SAFETY INSTRUCTIONS

Please save these instructions. This manual contains important safety and operating instructions. Read all instructions and 
follow them with each use of this product.

1.   SAVE THESE INSTRUCTIONS. This manual contains important safety and operating instructions. You may need to refer to 

these instructions at a later date.

2.   CAUTION. To reduce risk of injury, charge lead-acid wet cell, gel or AGM automotive type rechargeable batteries. Other types 

of batteries may burst causing personal injury and property damage.

3.   Do not expose charger to rain or snow.
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.

5.   To reduce risk of damage to electric plug and cord, pull by plug rather than cord when disconnecting charger.
6.   Make sure cord is located so that it will not be stepped on, tripped over, or otherwise subjected to damage or stress.
7.   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:

a.   The pins on the plug of the extension cord are the same number, size and shape as those of the plug on the charger;
b.   That extension cord is properly wired and in good electrical condition;
c.   If the length of the extension cord is less than 15 meter, use a 0.75mm2 cord, If 30 metre - 1mm2, 60 meter -1.5mm2.
8.   Do not operate charger with damaged cord or plug, replace the cord or plug immediately.
9.   Do not operate charger if it has received a sharp blow, been dropped, or otherwise damaged in any way; take it to a qualified 

serviceman.

10. 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.

11. To reduce risk of electric shock, unplug charger form outlet before attempting any maintenance or cleaning. Turning off 

controls will not reduce this risk.

12. 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 TO READ THIS MANUAL AND FOLLOW 
THE INSTRUCTIONS EXACTLY EACH TIME BEFORE USING 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 marking on these products and on engine.

PERSONAL SAFETY PRECAUTIONS

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.   Have plenty of fresh water and soap nearby in case battery acid contacts skin, clothing, or eyes.
3.   Wear complete eye protection, and clothing protection. Avoid touching eyes while working near battery.
4.   If battery acid contacts skin or clothing, wash immediately with soap and water. If acid enter 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 the charger for charging Lead acid, Gel, Calcium, AGM and EFB 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.

9.   NEVER charge a frozen battery.
