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.


M39772

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).

• 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.
