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.

5. Remove 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:

M73449

· The vent holes in the cap must be open.

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

9. Install the battery. Install the hose in the hole of the battery base and through the hole in the side of the frame. Install the hold-down and screw (E) on each side of the battery.

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. · Flush eyes with water for 15-30 minutes if acid is splashed into eyes. · If acid is swallowed, get medical attention immediately.

1. Lift and open hood.

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

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

MIF

MIF

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.

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.

Keep battery fully charged

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

MIF

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.)

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

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

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.
