MAINTENANCE PROCEDURE 4.9.1.c CHECK LEVEL OF BATTERY ELECTROLYTE Carry out this check before operating the machine. Do not use the battery if the battery electrolyte level is below the LOWER LEVEL line. This will accelerate deterioration of the inside of the battery and reduce the service life of the battery. In addition, it may also cause an explosion. The battery generates flammable gas and there is danger of explosion, so do not bring fire or sparks near the battery. Battery electrolyte is dangerous. If it gets in your eyes or on your skin, wash it off with a large amount of water and consult a doctor.
When adding distilled water to the battery, do not allow the battery electrolyte to go above the UPPER LEVEL line. If the electrolyte level is too high, it may leak and cause damage to the paint surface or cor- rode other parts. IMPORTANT When adding distilled water in cold weather, add it before starting operations in the morning to prevent the electrolyte from freezing. Inspect the battery electrolyte level at least once a month and follow the basic safety procedures given below. When Checking Electrolyte Level from Side of Battery If it is possible to check the electrolyte level from the side of the battery, check as follows. 1. Open the cover at the right side of the machine. 2.
Use a wet cloth to clean the area around the electrolyte level lines and check that the electrolyte level is between the UPPER LEVEL (U.L.) and LOWER LEVEL (L.L.) lines. If the battery is wiped with a dry cloth, static electricity may cause a fire or explosion. 3. If the electrolyte level is below the midway point between the U.L. and L.L. lines, remove cap (1) and add distilled water to the U.L. line. NOTE If distilled water is added to above the U.L. line, use a syrin- ge to lower the level to the U.L. line. Neutralize the removed fluid with baking soda (sodium bicarbonate), then flush it away with a large amount of water or consult your Komatsu Utility Dealer or battery maker. 4.
After adding distilled water, tighten cap (1) securely. 180 WARNING
