Safety Instructions

! Safety Guidlines

1 General Safety Precautions

1.IMPORTANT SAFETY INSTRUCTIONS. IT IS OF UTMOST

IMPORTANCE THAT BEFORE USING YOUR CHARGER, YOU READ THIS MANUAL AND FOLLOW THE SAFETY AND OPERATING INSTRUCTIONS EXACTLY. SAVE THESE INSTRUCTIONS.

Risk of explosive gases

Batteries generate explosive gases during normal operation, and when discharged or charged.

1.1To reduce risk of battery explosion, follow these safety instructions and those published by the battery manufacturer and the manufacturer of any equipment you intend to use in the vicinity of a battery. Review cautionary marking on these products and on the engine, and on the vehicle or equipment containing the battery.

Charging a non-rechargeable battery may cause the battery to burst.

To reduce the risk of injury, only charge rechargeable lead-acid type batteries including maintenance-free, low-maintenance, or deepcycle batteries.

If you are uncertain as to the type of battery you are attempting to charge, or the correct procedure for checking the battery’s state of charge, contact the seller or battery manufacturer.

1.2Use 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.

1.3To reduce risk of damage to the electric plug and cord, pull by the plug rather than by the cord when disconnecting the charger.

1.4Position the AC and DC leads to avoid tripping over them and to prevent damage by hood, doors, or moving engine parts; protect from heat, oil, and sharp edges.

1.5Do not operate the charger if it has received a sharp blow, been dropped or otherwise damaged in any way; take it to a qualified service center.

1.6Do not disassemble charger; take it to a qualified service center when repair is required. Incorrect reassembly may result in a risk of electric shock or fire.

1.7To reduce risk of electric shock, unplug the charger from the AC outlet before attempting any maintenance or cleaning. Turning off the controls will not reduce this risk.

Remove marine “boat” batteries and charge them on shore.

Charging marine batteries on-board requires specially designed equipment for marine use.

1.8Connect and disconnect the battery leads only when the AC supply cord is disconnected.

1.9Do not overcharge the battery. (See sections 3 and 10 in the safety instructions)

1.10Charge the battery in a dry, well-ventilated area.

1.11Never place articles on or around the charger, or locate the charger in a way that will restrict the flow of cooling air through the cabinet.

1.12An extension cord should not be used unless absolutely necessary. (See paragraph 4.3.)

1.13Have a damaged cord or plug replaced immediately.

1.14Do not expose the charger to rain or snow.

2 Personal Precautions

2.1Always have someone within range of your voice, or close enough to come to your aid, when working around lead acid batteries.

2.2Have plenty of fresh water and soap nearby in case battery acid contacts skin, clothing or eyes.

2.3Wear complete eye protection, clothing protection, and wear rubber soled shoes. Place damp cloth over battery to protect against acid spray. When ground is very wet or covered with snow, wear rubber boots. Avoid touching eyes while working near battery.

2.4If battery acid contacts skin or clothing, wash immediately with soap and water. If acid enters the eye, immediately flush with cold running water for at least 10 minutes, and seek medical attention.

2.5NEVER smoke or allow a spark or flame in vicinity of a battery or engine.

2.6Be extra cautious to reduce risk of dropping a metal tool onto the battery. It might spark or short circuit the battery or other electrical part that may cause an explosion.

2.7Before working with a lead-acid battery, remove personal metal items such as rings, bracelets, necklaces, watches, etc. A lead-acid battery can produce a short circuit current high enough to weld such items causing a severe burn.

Safety Instructions

GR8-1200 OEM

Non-rechargeable batteries may burst when charging causing personal injury and damage.

Only charge rechargeable lead-acid maintenance-free, low-maintenance or deepcycle batteries.

The charger is not intended to supply power to a lowvoltage electrical system other than applications using rechargeable, lead-acid type batteries. Do not use the battery charger for charging dry-cell batteries commonly used with home appliances. These batteries may burst and cause personal injury and property damage.

2.9 NEVER charge a frozen battery; thaw it out first.

3 Preparing To Charge The Battery

3.1If it is necessary to remove the battery from vehicle to charge it, 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.

3.2Be sure the area around the battery is well ventilated while the battery is being charged. Gas can be forcefully blown away by using a piece of cardboard or other nonmetallic material as a fan.

3.3Clean the battery terminals. Be careful to keep corrosion from coming into contact with your eyes.

3.4Add distilled water in each cell until the battery acid reaches the level specified by the manufacturer. This helps purge excessive gas from the cells. Do not overfill. For a battery without caps, carefully follow the manufacturer’s recharging instructions

3.5Study all battery manufacturer’s specific precautions such as removing or not removing cell caps while charging and recommended rates of charge.

3.6Determine 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 lowest rate. If the charger has only one voltage, verify that the battery voltage matches the voltage of charger.

For a charger not having an output voltage selector switch, determine the voltage of the battery by referring to car owner’s manual and make sure it matches the output rating of the battery charger.

4. Grounding & Power Cord Connections

4.1The charger must be grounded to reduce risk of electric shock. The charger is equipped with an electric cord having an equipment grounding conductor and a grounding plug. The plug must be plugged into an outlet that is properly installed and grounded in accordance with all lo-

cal codes and ordinances.

Hazardous voltage.

An improper connection can result in electric shock

To avoid electrical shock or burn, never alter the charger’s original AC cord and plug. Disconnect plug from outlet when charger is idle.

IFTHEPLUGDOES NOTFITTHEOUTLET, HAVEAPROPER OUTLET INSTALLED BY A QUALIFIED ELECTRICIAN.

4.2This battery charger is for use on a nominal 120-volt circuit and has a grounding plug that looks like the plug illustrated in Figure A. A temporary adapter, which looks like the adapter illustrated in Figures B and C, may be used to connect this plug to a two-pole receptacle as shown in Figure B, if a properly grounded outlet is not available. The temporary adapter should be used only until a properly grounded outlet can be installed by a qualified electrician.

Hazardous voltage.

An improper connection can result in electric shock

Before using an adapter be certain the center screw of the outlet plate is grounded. The rigid ear or lug extending from the adapter must be connected to a properly grounded outlet. Make certain it is grounded. If necessary, replace the original screw that secures the adapter ear or lug to the cover plate and make the ground connection to the grounded outlet.

USE OF AN ADAPTER IS NOT ALLOWED IN CANADA. IF A GROUNDING-TYPE RECEPTACLE IS NOT AVAILABLE, DO NOT USE THIS APPLIANCE UNTIL THE PROPER OUTLET IS INSTALLED BY A QUALIFIED ELECTRICIAN.

4.3An extension cord should not be used unless absolutely necessary. Use of an improper extension cord could result in a risk of fire and electric shock. If an extension cord must be used, make sure:

a.that the pins on plugs of the extension cord are the same number, size, and shape as those of the plug on the charger;

b.that the extension cord is properly wired and in good electrical condition;

c.that the wire size is large enough for the AC ampere rating of charger as specified in the following table.

6.1All switches should be set in the OFF position and AC cord should be DISCONNECTED from electrical outlet before you connect and disconnect the charger clamps. Never allow the clamps to touch each other.

6.2When attaching the charger clamps, be certain to make the best possible mechanical as well as electrical connection. This will tend to prevent the clamps from slipping off the connections, avoid dangerous sparking, and assure safer and more efficient charging. The clamps should be kept clean.

Hazardous voltage.

Can cause death or serious personal injury.

Setting the switches to “OFF” does not always disconnect the charger electrical circuit from the AC power cord or the DC charger clamps.

Risk of explosive gases

A spark near the battery may cause a battery explosion. Follow these steps when the battery is installed in the vehicle to reduce the risk of explosion.

7.1Before working on the vehicle, firmly apply the emergency brake and place the gear shift to NEUTRAL—shift an automatic transmission to PARK.

7.2Locate the charger as far away from the battery as the charger cords permit and position the AC and DC cords to avoid stepping on or tripping over them and to prevent damage by hood, doors, or moving engine parts.

7.3Stay clear of fan blades, belts, pulleys, and any other parts that can cause physical injury.

7.4Turn OFF all vehicle loads, including door lights, and correct any defects in the vehicle’s electrical system that may have caused low battery.

7.5Check the polarity of the battery posts. The POSITIVE (POS., P, +) post usually has a larger diameter than the

NEGATIVE (NEG., N,–) post.

7.6Determine which post of the battery is grounded (connected) to the chassis. If the negative post is grounded (as in most vehicles), see paragraph 7.7. If the positive post is grounded, see paragraph 7.8.

7.7For a negative-grounded vehicle, first connect the POSITIVE (RED) clamp from the charger to the POSITIVE (POS., P, +) ungrounded post of the battery. Then connect the NEGATIVE (BLACK) clamp to the NEGATIVE (NEG.,

N,–) post of the battery. Do not connect the clamp to the carburetor, fuel lines, or sheet-metal body parts. When disconnecting the charger, turn all switches to OFF, disconnect the AC cord, remove the clamp from the NEGATIVE battery terminal, and then remove the clamp from the POSITIVE battery terminal.
