INSTRUCTION MANUAL
SAFETY WARNINGS AND PRECAUTION
CAUTION: TO PREVENT BATTERY DAMAGE: DO NOT USE on gel batteries or
AGM (absorbed glass mat) type batteries.
Do not operate the Battery Maintainer in explosive atmospheres, such as in the presence of flammable
liquids, gases, or dust. Electrical products create sparks which may ignite the dust or fumes.
Keep bystanders, children, and visitors away while operating the Battery Maintainer. Distractions can
cause you to lose control. Protect others in the work area from sparks. Provide barriers or shields as needed.
Grounded products must be plugged into an outlet properly installed and grounded in accordance with all
codes and ordinances. Never remove the grounding prong or modify the plug in any way. Do not use any
adapter plugs. Check with a qualified electrician if you are in doubt as to whether the outlet is properly grounded.
Double insulated products are equipped with a polarized plug (one blade is wider than the other). This plug
will fit in a polarized outlet only one way. If the plug does not fit fully in the outlet, reverse the plug. If it still
does not fit, contact a qualified electrician to install a polarized outlet. Do not change the plug in any way.
Double insulation eliminates the need for the three wire grounded power cord and grounded power supply system.
Avoid body contact with grounded surfaces such as pipes, radiators, ranges, and refrigerators. There is an
increased risk of electric shock if your body is grounded.
Do not abuse the Power Cord. Never use the Power Cord to carry the Battery Maintainer or pull the Plug from
an outlet. Keep the Power Cord away from heat, oil, sharp edges, or moving parts. Replace damaged Power
Cords immediately. Damaged Power Cords increase the risk of electric shock.

An extension cord should not be used unless absolutely necessary. If an extension cord is used, make sure
wire size is large enough to operate battery maintainer.
Stay alert, watch what you are doing, and use common sense when operating the Battery Maintainer. Do not
operate the Battery Maintainer under the influence of drugs, alcohol, or medication.
Dress properly. Do not wear loose clothing or jewelry. Contain long hair. Keep your hair and clothing away
from the Battery Maintainer. Loose clothes, jewelry, or long hair can be caught in the Battery Maintainer, causing
personal injury.
Use safety equipment. Always wear eye protection during assembly, use, and maintenance.
Do not overload the Battery Maintainer. Use the correct Battery Maintainer for your application. The Battery
Maintainer will perform better and safer at the speed and capacity for which it is designed.
Disconnect the Power Cord Plug from the power source before making any adjustments, changing
accessories, or storing the Battery Maintainer. Such preventive safety measures reduce the risk of turning on the
product accidentally.
Maintain the Battery Maintainer with care. Do not use a damaged Battery Maintainer. Tag damaged Battery
Maintainer “Do not use” until repaired.

electrical equipment in close proximity to a heart pacemaker could cause interference or failure of the
pacemaker.
Do not expose the Battery Maintainer equipment to moisture, rain or wet conditions. Water entering electrically
powered equipment will increase the risk of electric shock.
Do not service or disassemble the battery maintainer.
Follow all warnings, cautions and instructions from battery manufacturer.
WARNING: Risk of Explosive Gases: Working around a Lead-acid battery is dangerous. Lead-acid
batteries generate explosive gases during normal operation. It is very important that you read these
instructions every time you use this battery maintainer and follow them.
