2. Inspection and Adjustment Battery structure (1) Electrolyte level z Check the level of fluid in the battery. When the amount of fluid nears the lower limit, fill with battery fluid (available in the market) to the upper limit. If operation continues with insufficient battery fluid, the battery life is shortened, and the battery may overheat and explode. z Battery fluid tends to evaporate more quickly in the summer, and the fluid level should be checked earlier than the specified times. z If the engine cranking speed is so slow that the engine does not start up, recharge the battery. z If the engine still will not start after charging, replace the battery.
z Remove the battery from the battery mounting of the machine unit after daily use if letting the machine unit leave in the place that the ambient temperature could drop at -15 or less. And store the battery in a warm place until the next use the unit to start the engine easily at low ambient temperature. (2) Battery charge Use a battery tester or hydrometer and check the battery condition. If the battery is discharged, recharge it.
(a) Measurement with a battery tester When checking the battery with the batter tester, connect the red clip of the tester to the battery positive (+) terminal and black clip to the battery negative (-) terminal by pinching them securely, and judge the battery charge level from the indicator position. Green zone: Normal Yellow zone: Slightly discharged Red zone: Defective or much discharged 30
