IMPORTANT SAFETY
INSTRUCTIONS FOR CANADA & USA
THIS PORTION OF THE MANUAL CONTAINS IMPORTANT SAFETY INSTRUCTIONS FOR
THE OPTIMATE 7 12V-24V BATTERY CHARGER. IT IS OF THE UTMOST IMPORTANCE
THAT EACH TIME, BEFORE USING THE CHARGER, YOU READ AND EXACTLY FOLLOW
THESE INSTRUCTIONS. SAVE THESE INSTRUCTIONS.
Automatic charger for 12 & 24V lead-acid batteries
DO NOT USE FOR NiCd, NiMH, Li-Ion OR NON-RECHARGEABLE BATTERIES.
1. CAUTION : CLASS II APPLIANCE. DO NOT CONNECT TO GROUND.
2. Do not expose charger to rain or snow.
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. 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 extension cord must be used make sure that :
a) pins on plug of extension cord are the same number, size and shape as those of plug on charger.
b) the extension cord is properly wired and in good electrical condition, and
c) the conductor wire size is large enough for the AC ampere rating of the charger as specified in the table below.

6. Do not operate charger with damaged cord or plug – replace the cord or plug immediately.
7. 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.
8. 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.
9. To reduce risk of electric shock, unplug the charger from outlet before attempting any maintenance or cleaning.
Turning off controls will not reduce this risk. Clean only with slightly moist, not wet, cloth. Do not use solvents.
10. 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 the battery manufacturer
and manufacturer of any equipment you intend to use in vicinity of the battery. Review cautionary marking on
these products and on engine.
11. PERSONAL PRECAUTIONS.
a) Someone should be within range of your voice OR close enough to come to your aid when you work near a lead-acid battery.
b) Have plenty of fresh water and soap nearby in case battery acid contacts skin, clothing or eyes.
c) Wear complete eye protection and clothing protection. Avoid touching eyes while working near battery.
d) If battery acid contacts or enters eye, flood eye with cold running water for at least 10 minutes and get medical
attention immediately. If battery acid contacts skin or clothing, wash immediately with soap and water. If acid enters
an eye, immediately flood eye with running cold water for at least 10 minutes and get medical attention immediately.
e) NEVER smoke or allow a spark or flame in vicinity of battery or engine.
f) 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.
g) 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.
i) NEVER charge a frozen battery.
