. MAINTENANCE SERVICE PROCEDURE CHECK BATTERY ELECTROLYTE LEVEL Carry out this procedure before operating the machine. WARNING the 1. Open the cover of the battery box. There are two battery boxes: One on each side at the rear 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. 4.
If distilled water has been added to any cell of cap (1), add distilled water also to the other cells. 5. Clean the vents of the battery caps, then close the caps securely. Keep the top of the battery clean and wipe it with a wet cloth. the 4 - 45 EVERY 250 HOURS SE RVICE Maintenance for every 50 an d 100 hours service should be carried out at the sa Do not use the battery if the b attery electrolyte level is below the LOWER LEVEL line. T his will accelerate deterioration inside of the battery and redu ce the service life of the battery. In addition, it may cause an explosion. or sparks near the battery.
The battery generates flamma ble gas and there is danger of explosion, do not bring fire Battery electrolyte is dangero us. If it gets in your eyes or on your skin, wash it off with a large amount of water and con doctor. When adding distilled water to the battery, do not allow the battery electrolyte to go above the UPPER LEVEL line. may leak and cause damage to the paint surface or corrode other parts. electrolyte level is too high, it may leak and cause damage to the paint surface or corro NOTICE If there is a fear that the battery w ater may freeze after refilling with purified water (e.g.
comm ercially available replenishment for a battery), do the replenishm ent before the day's work on the next day. Inspect the battery electrolyt e level at least once a month and follow the basic sa fety procedures given below WHEN CHECKING ELECTROLYTE LEVEL FROM SIDE OF BATTERY If it is possible to check the e lectrolyte level from the side of the battery, check a REMARK If distilled water is added to above the U.L. line, use a syringe to lower the level to the U.L. line. Neutraliz removed fluid with baking sod a (sodium bicarbonate), then flush it away with a larg e amount of water or consult Komatsu distributor or batter y maker.
