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.

1. Remove grille.


IMPORTANT: Avoid damage! DO NOT fill cells to the bottom of the filler neck (B). Electrolyte can overflow when battery is charged and cause damage.

2. Remove battery manifold cap(s).

m39772

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

4. Add distilled water if necessary.

NOTE: On Early Model batteries, be sure manifold cap hose is behind positive cable.

5. Install manifold cap(s).

6. Install grille.

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.

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.

· 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:

m61341

c CAUTION: 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.

Using Booster Battery

c CAUTION: Avoid injury! The battery produces a flammable and explosive gas. The battery may explode:

· DO NOT attempt to jump start a frozen battery. Warm to 16 degrees C (60 degrees F).

· DO NOT smoke near battery.

· Wear eye protection and gloves.

· Keep sparks and flames away.

· DO NOT connect the negative (-) booster cable to the negative (-) terminal of the discharged battery. Connect at a good ground location away from the discharged battery.

A - Booster Battery

B - Disabled Vehicle Battery

1. Connect positive (+) booster cable to booster battery (A) positive (+) post (C).

2. Connect the other end of positive (+) booster cable to the disabled vehicle battery (B) positive (+) post (D).

3. Connect negative (-) booster cable to booster battery negative (-) post (E).

4. Connect the other end (F) of negative (-) booster cable to a metal part of the disabled machine frame away from battery.

5. Start the engine of the disabled machine and run machine for several minutes.

6. Carefully disconnect the booster cables in the exact reverse order: negative cable first and then the positive cable.

Cleaning and Gapping Spark Plugs

c CAUTION: Avoid injury! Before you remove spark plugs:
