Check battery electrolyte and specific gravity of battery electrolyte
Battery electrolyte: every 250 hours
Specific gravity of battery electrolyte: every 500 hours
If there seems to be a problem in starting an engine due to a flat battery, carry out the checks
by following the procedures below:
Ordinary type battery:
Check battery electrolyte level and if the level is not within the specified level, add distilled
water.
Measure specific gravity of battery electrolyte, and if it shows below 1.24, recharge the battery
immediately.
Refer to 5.5.4
for method of specific gravity measurement and recharging the battery.
Enclosed type battery:
Check the indicator on top surface of the battery.
If the indicator shows that charge is needed, recharge the battery immediately.
If specific gravity of battery electrolyte does not rise in spite of replenishing distilled water or
charging battery, be sure to replace battery with new one quickly.
