10. To reduce the risk of electric shock, unplug the charger from the outlet before attempting any maintenance or cleaning. Turning off controls will not reduce this risk.
11. WARNING:
    RISK OF EXPLOSIVE GASES.
    1. WORKING IN THE 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.
    2. To reduce the risk of battery explosion, follow these instructions and those published by the battery manufacturer and the manufacturer of any equipment you intend to use in the vicinity of the battery.. Review cautionary markings on these products and on the engine.

PERSONAL SAFETY PRECAUTIONS

1. Consider having someone close enough by 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 and clothing protection. Avoid touching your eyes while working near a battery.
4. If battery acid contacts skin or clothing, wash immediately with soap and water. If acid enters the eye, immediately flood the 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 the vicinity of the battery or engine.
6. Be extra cautious to reduce the risk of dropping a metal tool onto the battery. It might spark or short-circuit the battery or other electrical parts, which may cause an 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 a charger for charging only LEAD-ACID (STD or AGM) rechargeable batteries with recommended rated capacities of
   22-59Ah (12V). It is not intended to supply power to a low-voltage electrical system other than in a starter-motor application. Do not use a battery charger for charging dry-cell batteries that are commonly used with home appliances. These batteries may burst and cause injury to persons and property damage.
9.  NEVER charge a frozen battery.
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.

PREPARING TO CHARGE

1. If necessary to remove the battery from the vehicle to charge, always remove the grounded terminal from the battery first. Make sure all accessories in the vehicle are off, so as not to cause an arc.
2. Be sure the area around the battery is well ventilated while the battery is being charged.
3. Clean battery terminals. Be careful to keep corrosion from coming in contact with your eyes.
4. Add distilled water in each cell until the battery acid reaches the level specified by the battery manufacturer. Do not overfill. For a battery without removable cell caps, such as valve-regulated lead-acid batteries, carefully follow the manufacturer’s recharging instructions.
5. Study all battery manufacturers’ specific precautions while charging and recommended rates of charge.
6. Determine the voltage of the battery by referring to the car owner’s manual, and make sure that the output voltage selector switch is set at the correct voltage. If the charger has an adjustable charge rate, charge the battery initially at the lowest rate.

CHARGER LOCATION

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

DC CONNECTION PRECAUTIONS

1. Connect and disconnect DC output clips only after setting any charger switches to the “off” position and removing the AC cord from the electric outlet. Never allow clips to touch each other.
2. Attach clips to the battery and chassis, as indicated in sections 6 and 7.

FOLLOW THESE STEPS WHEN THE BATTERY IS INSTALLED IN THE VEHICLE

WARNING: A SPARK NEAR THE BATTERY MAY CAUSE A BATTERY EXPLOSION. TO REDUCE THE RISK OF A SPARK NEAR THE BATTERY:

1. Position the AC and DC cords to reduce the risk of damage from the hood, door, or moving engine parts.
2. Stay clear of fan blades, belts, pulleys, and other parts that can cause injury to persons.
3. Check the polarity of battery posts. POSITIVE (POS, P, +) battery post usually has a larger diameter than NEGATIVE (NEG, N,–) post.
4. Determine which post of the battery is grounded (connected) to the chassis. If the negative post is grounded to the chassis (as in most vehicles), see (6.5). If a positive post is grounded to the chassis, see (6.6).
5. For a negative-grounded vehicle, connect the POSITIVE (RED) clip from the battery charger to the POSITIVE (POS, P, +) ungrounded post of the battery. Connect NEGATIVE (BLACK) clip to vehicle chassis or engine block away from battery. Do not connect the clip to the carburetor, fuel lines, or sheet-metal body parts. Connect to a heavy-gauge metal part of the frame or engine block.
6. For a positive-grounded vehicle, connect the NEGATIVE (BLACK) clip from the battery charger to the NEGATIVE (NEG, N, –) ungrounded post of the battery. Connect the POSITIVE (RED) clip to the vehicle chassis or engine block away from the battery. Do not connect the clip to the carburetor, fuel lines, or sheet-metal body parts. Connect to a heavy-gauge metal part of the frame or engine block.
7. When disconnecting the charger, turn the switches off, disconnect the AC cord, remove the clip from the vehicle chassis, and then remove the clip from the battery terminal.
8. See Operating Instructions for length of charge information.

FOLLOW THESE STEPS WHEN THE BATTERY IS OUTSIDE THE VEHICLE

WARNING: A SPARK NEAR THE BATTERY MAY CAUSE A BATTERY EXPLOSION. TO REDUCE THE RISK OF A SPARK NEAR THE BATTERY:

BATTERY CHARGING TIMES

Times are based on a 50% discharged battery and may change, depending on the age and condition of the battery.

AUTOMATIC CHARGING MODE

When an Automatic Charge is performed, the charger switches to maintenance mode automatically after the battery is charged.

ABORTED CHARGE

If charging cannot be completed normally, charging will abort. When charging aborts, the charger’s output is shut off, and the CLAMPS REVERSED/BAD BATTERY (red) LED will light. Do not continue attempting to charge this battery. Check the battery and replace, if necessary.

DESULFATION MODE

Desulfation could take 8 to 10 hours. If desulfation fails, charging will abort, and the CLAMPS REVERSED/BAD BATTERY (red) LED will light.

COMPLETION OF CHARGE

Charge completion is indicated by the CHARGED/MAINTAINING (green) LED. When pulsing, the charger has switched to the maintenance mode of operation.

MAINTAIN MODE (FLOAT MODE MONITORING)

When the CHARGED/MAINTAINING (green) LED is pulsing, the charger has started maintain mode. In this mode, the charger keeps the battery fully charged by delivering a small current when necessary. If the charger has to provide its maximum maintain current for a continuous 112-hour period, it will go into abort mode (see Aborted Charge section). This is usually caused by a drain on the battery, or the battery could be bad. Make sure there are no loads on the battery. If there are, remove them. If there are none, have the battery checked or replaced.

MAINTAINING A BATTERY

The SC1305 charges and maintains 12-volt batteries, keeping them at full charge.

NOTE: The maintain mode technology allows you to safely charge and maintain a healthy battery for extended periods. However, problems with the battery, electrical problems in the vehicle, improper connections, or other unanticipated conditions could cause excessive current draws. As such, occasionally monitoring your battery and the charging process is required.

USING THE ENGINE START SETTING

Your battery charger can be used to jump-start your car if the battery is low. Follow all safety instructions and precautions for charging your battery. Wear complete eye and clothing protection.

WARNING: Using the ENGINE START setting WITHOUT a battery installed in the vehicle could cause damage to the vehicle’s electrical system.

NOTE: If you have charged the battery and it still will not start your car, do not use the Engine Start setting, or it could damage the vehicle’s electrical system. Have the battery checked.

1. With the charger unplugged from the AC outlet, connect the charger to the battery, following the instructions given in Charging a Battery in the Vehicle.
2. With the charger plugged in and connected to the battery of the vehicle, set the rate selection to the Engine Start position.
3. Crank the engine until it starts or 5 seconds pass. If the engine does not start, wait a few minutes before cranking again. NOTE: During extremely cold weather, or if the battery is under 2 volts, use the 10A Boost setting for 5 minutes before cranking the engine.
4. If the engine fails to start, boost the battery for 5 more minutes before attempting to crank the engine again.
5. After the engine starts, unplug the AC power cord before disconnecting the battery clamps from the vehicle.
   NOTE: If the engine does turn over but never starts, there nisonooproblem with the starting system; there is a problem somewhere else with the vehicle. STOP cranking the engine until the other problem has been diagnosed and corrected.

MAINTENANCE AND CARE

A minimal amount of care can keep your battery charger working properly for years.

• Clean the clamps each time you are finished charging. Wipe off any battery fluid that may have come in contact with the clamps to prevent corrosion.
• Occasionally, cleaning the case of the charger with a soft cloth will keep the finish shiny and help prevent corrosion.
• Coil the input and output cords neatly when storing the charger. This will help prevent accidental damage to the cords and charger.
• Store the charger unplugged from the AC power outlet in an upright position.
