10. Tighten the clamp nut securely. BATTERY CHARGING Battery electrolyte temperature may temporarily be allowed to rise to 55°C (131°F).
Increase of electrolyte temperature above 55°C (131°F) is harmful to the battery,
causing deformation of battery cell, decrease in life of battery, etc.
case is cracked or leaking to protect hands from
the electrolyte. A suitable pair of rubber gloves
(not the household type) should be worn when
removing battery by hand.
WARNING:When batteries are being charged, an explosive gas
forms beneath the cover of each cell. Do not smoke
near batteries on charge or which have recently
been charged. Do not break live circuits at the
terminals of the batteries on charge. A spark will
occur where the live circuit is broken. Keep all open
flames away from the battery.
