Cleaning Or Replacing Battery

c CAUTION: Avoid injury! Battery gas can explode: · Keep sparks and flames away from batteries. Use a flashlight to check battery electrolyte level. · Never check battery charge by placing a metal object across the posts. Use a voltmeter or hydrometer. · Always remove grounded (-) battery clamp first and replace it last.

4. Remove the screw (D) and hold-down bracket from each side of the battery.

5. Remove the battery.

6. Clean the battery and related parts with a solution of one part baking soda and four parts water. Keep the solution out of the battery cells.

7. Rinse all the parts and let them dry.

8. Check the battery:

· The vent holes in the cap must be open.

· The electrolyte level must be 6 mm (1/4-in.) above the plates.

13. Lower the hood.

Checking Battery Electrolyte Level

c CAUTION: Avoid injury! Sulfuric acid in battery electrolyte is poisonous. It is strong enough to burn skin, eat holes in clothing, and cause blindness if splashed into eyes. · Wear eye protection and avoid spilling or dripping electrolyte.

M73361

1. Lift and open hood.

2. Remove battery manifold cap (A).

M39772

3. Electrolyte (C) should be 6 mm (1/4 in.) above plates (D).

4. Add distilled water if necessary.

5. Install manifold cap. Be sure manifold cap hose is behind positive cable.

6. Lower hood.

Charging The Battery

c CAUTION: Avoid injury! BE VERY CAREFUL: Battery fluid (electrolyte), is a solution of water and sulfuric acid. It is very harmful to eyes, skin, or clothing. · Wear goggles or an eye shield when you work with a battery. · If the acid contacts your eyes, skin, or clothing, flush the area immediately with water. Get medical help, if necessary. A battery gives off gas which can explode. An exploding battery will spray sulfuric acid in all directions. · Keep cigarettes, sparks, and flames away from the battery. · Charge the battery in an area with good ventilation.

Follow instructions on the battery charger or in the charger operator's manual, or use the instructions below as a guide.

Charging The Battery (Continued)

Before you charge a battery:

· Wait until the battery has warmed to room temperature. Do not charge a frozen battery.

· Check the electrolyte level of each cell. (See Checking Battery Electrolyte Level in this section.)

· Install the battery cap(s) on the battery.

Turn OFF and unplug the charger before you connect cables to the battery or disconnect cables from the battery.

If the battery becomes warm to touch during charging:

· Reduce the charging rate OR

· Stop charging the battery until it cools.

c CAUTION: Avoid injury! DO NOT charge a frozen battery. Battery gases can explode. Keep cigarettes, sparks, and flames away from battery.

Keep battery fully charged.

1. Remove and clean battery. (See Cleaning Or Replacing Battery in this section.)

2. Check electrolyte level. (See Checking Battery Electrolyte Level in this section.)

c CAUTION: Avoid injury! To avoid injury, before you connect or disconnect charger cables to battery, unplug charger cord.

3. Leave cell caps on battery while you charge it.

4. Connect positive (+) charger cable to positive (+) battery terminal.

5. Connect negative (-) charger cable to negative (-) battery terminal.

6. Plug in charger cord.

7. Charge battery.

8. Unplug charger cord. Remove charger cables.

9. Install battery.

Charging Rates

See your battery charger or charger operator's manual for information on charging. Or read the information below to FULLY CHARGE your battery.

For a charger with a CURRENT ADJUSTMENT CONTROL:

· Adjust the control to 10 amps.

· Charge the battery for 6-8 hours.

For a charger with a switch for MAINTENANCE FREE, DEEP CYCLE, or NORMAL (CONVENTIONAL) setting:

· Use the MAINTENANCE FREE or DEEP CYCLE setting.

For a charger with SLOW CHARGE, FAST CHARGE, or BOOST CHARGE setting:

· DO NOT use the BOOST CHARGE setting.

· Use the SLOW CHARGE setting:

· - For a charger rated at less than 10 amps.

· - For 3-16 hours.

· Use the FAST CHARGE setting:

· - For a charger rated at 10 amps.

· - For 5-8 hours.

NOTE: NOTE: Your charger may have an AUTOMATIC STOP to prevent charging the battery:

· When the battery is fully charged OR

· When the battery is not in condition to take a charge.

Using Booster Battery

c CAUTION: Avoid injury! Battery gas is explosive: · DO NOT smoke while you boost battery. · Keep all flames and sparks away. · DO NOT connect booster battery negative (-) cable to starting vehicle negative (-) terminal.

M71044

Connect positive (+) booster cable to booster battery positive (+) post (D).

Connect the other end of positive (+) booster cable to vehicle battery positive (+) post (A).

Connect negative (-) booster cable to booster battery negative (-) post (C).

Connect the other end of negative (-) booster cable to engine ground (B) away from battery.

Checking The Indicator Lights
