4.8 Service procedure Maintenance Every 250 hours service 2. Use a wet cloth to clean the area around the electrolyte level lines and check that the electrolyte level is between the (MAXIMUM) UPPER LEVEL and (MINIMUM) LOWER LEVEL lines. If the battery is wiped with a dry cloth, static electricity may cause a fire or explosion. (maximum) Upper Level Lower level (minimum) GK032268 3. If the electrolyte level is below the midway point between the (MAXIMUM) UPPER LEVEL and (MINIMUM) LOWER LEVEL lines, remove cap (1) and add distilled water to the (MAXIMUM) UPPER LEVEL 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. GK032269 1 Keep the top of the battery clean and wipe it with a wet cloth. REMARK If distilled water is added to above the (MAXIMUM) UPPER LEVEL line, use a syringe to lower the level to the (MAXI- MUM) UPPER LEVEL line. Neutralize the removed fluid with baking soda (sodium bicarbonate), then flush it away with a large amount of water or consult your KOMATSU distributor or battery maker.
When it is impossible to check electrolyte level from side of battery If it is impossible to check the electrolyte level from the side of the battery, or there is no display of the (MAXIMUM) UPPER LEVEL line on the side of the battery, check as follows. 1. Open the cover of the battery box. There are two battery boxes: One on each side at the rear of the machine. 2. Remove cap (1) at the top of the battery, look through the water filler port, and check the electrolyte surface. If the electrolyte does not reach the sleeve, add distilled water so that the level reaches the bottom of the sleeve (MAXIMUM) (UPPER LEVEL line) without fail. 3.
If distilled water has been added to any cell of cap (1), add distilled water also to the other cells. GK032269 1 WA150-5H – VEAM934100 4-45
