Personal injury may occur from failure to properly service the batteries.

Batteries give off flammable fumes that can ex-plode.; Electrolyte is an acid and can cause personal injury if it contacts the skin or eyes.

Prevent sparks near the batteries. Sparks could cause vapors to explode.; Do not allow jumper cable ends to contact each other or the engine.; Improper jumper cable connections can cause an explosion.

Always wear protective glasses when working with batteries.

1. Turn the engine start switch to the OFF position.

The V-belt must be tensioned correctly. Failure to tension the belt properly could damage the belt and/or to the belt guide, or water pump bearing.

Do not allow the belt to come in contact with any foreign substance such as oil or grease as damage to the V-belt may occur.

For maximum engine performance and maximum utilization of your engine, inspect the belts for wear and for cracking.; Check the belt tension. Adjust the belt tension in order to minimize belt slippage. Belt slippage will decrease the belt life.; Belt slippage will also cause poor performance of the alternator and of any driven equipment.

If new belts are installed, recheck the belt adjustment after 5 minutes of operation.; If two belts or more are required for an application, replace the belts in belt sets.; If only one belt of a pair is replaced, the new belt will carry more load.; This is because the older belts are stretched.; The additional load on the new belt could cause the new belt to break.

2. Apply approximately 100 N (22 |b) of force midway between the pulleys.

3. Measure the deflection of the belt. The belt should deflect 6 to 8 mm (4/16 to 5/16 inch).
