. MAINTENANCE SERVICE PROCEDURE the 4 - 44 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 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 (2), and check the electrolyte surface. If the electrolyte does not reach the sleeve (3), add distilled water so that the level reaches the bottom of the sleeve (UPPER LEVEL line) without fail. (A) Suitable level:

Electrolyte level is up to bottom of sleeve, so surface tension causes electrolyte surface to bulge and poles appear bent. (B) Low: Electrolyte level is not up to bottom of sleeve, so poles appear straight and not bent. 3. If distilled water has been added to any cell of cap (1), add distilled water also to the other cells. 4. After adding distilled water, tighten cap (1) securely. REMARK If water is added to above the bottom tip of the sleeve, use a pipette to remove electrolyte. Neutralize the removed electrolyte with sodium bicarbonate, then flush it away with a large amount of water. If necessary, contact your Komatsu distributor or your battery maker.
