MAINTENANCE PROCEDURE 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 UPPER LEVEL line on the side of the battery, check as follows. 1. Open the engine rear cover and cooling cover. For de- tails, see Section "3.2.10 COOLING COVER". 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 (UP- PER LEVEL line) without fail.
Use the diagram below for reference, and check if the electrolyte reaches the bottom of the sleeve. 3. After adding distilled water, tighten cap (1) securely. NOTE If distilled water is added to above the bottom of the sleeve, use a syringe to lower the level to the bottom of the sleeve. 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. When It is Possible to Use Indicator to Check Electrolyte Level If it is possible to use and indicator to check the electrolyte level, follow the instructions given. 181
