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.

a sharp blow, been dropped, or otherwise 

damaged in any way; take it to a qualified 

serviceman.

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 charger for charging LEAD-ACID 

(STD or AGM) rechargeable batteries with 

recommended rated capacities of 24Ah 

(6V) and 44-75Ah (12V). 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.

2.10 WARNING:

 This product contains one 

or more chemicals known to the State 

of California to cause cancer and birth 

defects or other reproductive harm.
