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

10. WARNING – RISK OF EXPLOSIVE GASES.

    • 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 MAINTAINER.
      b.o 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.

11. PERSONAL PRECAUTIONS

12. Consider having someone close enough by 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.

13. 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.

    • NEVER smoke or allow a spark or flame in vicinity of battery or engine.
    • 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.
    • 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.
    • Use Maintainer for charging Gel, LEAD-ACID orAbsorbed Glass Mat (AGM) batteries only. It is not intended to supply power to a low voltage electrical system other than in a starter-motor application. Do not use battery Maintainer 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.
    • NEVER charge a frozen battery.

14. PREPARING TO CHARGE

    • If necessary to remove battery from vehicle to charge, always remove grounded terminal from battery first. Make sure all accessories in the vehicle are off, so as not to cause an arc.
    • Be sure area around battery is well ventilated while battery is being charged.

15. Clean battery terminals. Be careful to keep corrosion from coming in contact with eyes.

    • Add distilled water in each cell until battery acid reaches level specified by battery manufacturer. Do not overfill. For a battery without removable cell caps, such as valve regulated lead acid batteries, carefully follow manufacturer’s recharging instructions.
    • Study all battery manufacturer’s specific precautions while charging and recommended rates of charge.
    • Determine voltage of battery by referring to vehicle owner’s manual and make sure it matches output rating of battery Maintainer.
    •  not place Maintainer or electrical connections on ground or floor.

16. MAINTAINER LOCATION

    • Locate Maintainer as far away from battery as DC cables permit.
    • Never place Maintainer directly above battery being charged; gases from battery will corrode and damage Maintainer.
    • Never allow battery acid to drip on Maintainer when reading electrolyte specific gravity or filling battery.
    • Do not operate Maintainer in a closed-in area or restrict ventilation in any way.
    • Do not set a battery on top of Maintainer.DC CONNECTION PRECAUTIONS

    • Position AC and DC cables to reduce risk of damage by hood, door, or moving engine part.
    • Stay clear of fan blades, belts, pulleys, and other parts that can cause injury to persons.
    • Check polarity of battery posts. POSITIVE (POS, P, +) battery post usually has larger diameter than NEGATIVE (NEG, N,–) post.
    • Determine which post of battery is grounded (connected) to the chassis. If negative post is grounded to chassis (as in most vehicles), see (e). If positive post is grounded to the chassis, see (f).
    • For negative-grounded vehicle, connect POSITIVE (RED) clip from battery Maintainer to POSITIVE (POS, P, +) ungrounded post of battery. Connect NEGATIVE (BLACK) clip to vehicle chassis or engine block away from battery. Do not connect clip to carburetor, fuel lines, or sheet-metal body parts. Connect to a heavy gauge metal part of the frame or engine block.
    • For positive-grounded vehicle, connect NEGATIVE (BLACK) clip from battery Maintainer to NEGATIVE (NEG, N, –) ungrounded post of battery. Connect POSITIVE (RED) clip to vehicle chassis or engine block away from battery. Do not connect clip to carburetor, fuel lines, or sheet-metal body parts. Connect to a heavy gauge metal part of the frame or engine block.
    • When disconnecting maintainer, disconnect AC cord, remove clip from vehicle chassis, and then remove clip from battery terminal.
    • See operating instructions for length of charge information.

19. FOLLOW THESE STEPS WHEN BATTERY IS OUTSIDE VEHICLE. A SPARK NEAR THE BATTERY MAY CAUSE BATTERY EXPLOSION. TO REDUCE THE RISK OF A SPARK NEAR BATTERY:
