Service the Battery Safely



c CAUTION: Avoid injury! Battery electrolyte contains sulfuric acid. It is poisonous and can cause serious burns:

• Wear eye protection and gloves.

• Keep skin protected.

• If electrolyte is swallowed, get medical attention immediately.

• If electrolyte is splashed into eyes, flush immediately with water for 15-30 minutes and get medical attention.

• If electrolyte is splashed onto skin, flush immediately with water and get medical attention if necessary.

The battery produces a flammable and explosive gas. The battery may explode:

• Do not smoke near battery.

• Wear eye protection and gloves.

• Do not allow direct metal contact across battery posts.

• Remove negative cable first when disconnecting.

• Install negative cable last when connecting.

Checking Battery Electrolyte Level

NOTE: Add only distilled water to replace battery electrolyte.

1. Park the machine safely. (See Parking Safely in the SAFETY section.)

2. Remove battery cell caps. Make sure cap vents are not plugged.

3. Check electrolyte level. Electrolyte (B) should be approximately halfway between bottom of filler neck (A) and top of plates (C).

IMPORTANT: Avoid damage! Do not overfill battery. Electrolyte can overflow when battery is charged and cause damage.


4. Add only distilled water if necessary.

5. Install battery cell caps.

Using Booster Battery

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

• Do not smoke or have open flame near battery.

• Wear eye protection and gloves.

• Do not jump start or charge a frozen battery. Warm battery to 16?C (60?F).

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).

IMPORTANT: Avoid damage! Electric charge from booster battery can damage machine components. Do not install negative booster cable to machine frame. Install only to the engine block.

Install negative booster cable away from moving parts in the engine compartment, such as belts and fan blades.


4. Connect the other end (F) of negative (–) booster cable to a metal part of the disabled machine engine block 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.

Replacing Fuses

1. Park machine safely. (See Parking Safely in the SAFETY section.)
