Do not check the battery by short-circuiting the positive and negative terminals with a metallic
piece.
Never operate the machine nor charge the batteries with the battery liquid level being kept lower
than the lower level. Continuing operation at this lower level will cause deterioration of such
parts as pole plates etc., and also it may cause explosion as well as reduction of battery life.
Add distilled water so that the liquid level may reach the middle level between the “UPPER
LEVEL” and “LOWER LEVEL” without any delay.
