MAINTENANCE Electrolyte Level Check --- every one month 1. Check the electrolyte level at least once a month. 2. Park the machine on level ground and stop the engine. 3. Check the electrolyte level. 3.1 When checking the level from the battery side: Clean around the level check lines with a wet towel. Don’t use a dry towel. Static electricity may be devel- oped, causing the battery gas to explode. Check if the electrolyte level is between U.L (Upper Level) and L.L (Lower Level). In case the electrolyte level is lower than the middle level between the U.L and L.L, immediately refill distilled water or commercial battery fluid.
Be sure to refill with distilled water before recharging (operating the machine). After refilling, securely tighten the filler plug. U.L (Upper Level) L.L (Lower Level) M146-07-109 Filler Port 3.2 When impossible to check the level from the battery side or no level check mark is indicated on the side: After removing the filler plug from the top of the bat- tery. Check the electrolyte level by viewing through the filler port. It is difficult to judge the accurate electrolyte level in this case. Therefore, when the electrolyte level is flush with the U.L, the level is judged to be proper. Then, referring to the right illustrations, check the level.
When the electrolyte level is lower than the bottom end of the sleeve, refill with distilled water or commercial battery fluid up to the bottom end of the sleeve. Be sure to refill with distilled water before recharging (operating the machine). After refilling, securely tighten the filler plug. Sleeve Upper Level Separator Top Lower Level M146-07-110 Proper Since the electrolyte surface touches the bottom end of the sleeve, the electrolyte surface is raised due to surface tension so that the electrode ends are seen curved. M146-07-111 Lower When the electrolyte surface is lower than the bottom end of the sleeve, the electrode ends are seen straight.
3.3 When an indicator is available to check the level, follow its check result. M146-07-112 4. Always keep around the battery terminals clean to pre- vent battery discharge. Check terminals for loose and/or rust. Coat terminals with grease or petroleum jelly to pre- vent corrosion build up. M409-07-072 7-73
