Battery Charging
DANGER
To avoid serious injury or death:
• When the battery is being activated, hydrogen and oxygen
gases in the battery are extremely explosive. Keep open
sparks and flames away from the battery at all times,
especially when charging the battery.
WARNING
To avoid serious injury:
• When charging the battery, ensure the vent caps are
securely in place (if equipped).
• When disconnecting the cable from the battery, start with
the negative terminal first.
When connecting the cable to the battery, start with the
positive terminal first.
• Never check battery charge by placing a metal object
across the posts.
Use a voltmeter or hydrometer.
(For accessible maintainable type batteries with removable vent
caps.)
1. Make sure each electrolyte (3) level is to the bottom of vent
wells (4), if necessary add distilled water in a well-ventilated
area.
2. The water in the electrolyte (3) evaporates during recharging.
Liquid shortage damages the battery. Excessive liquid spills
over and damages the machine.
3. To slow charge the battery, connect the battery positive terminal
to the charger positive terminal and the negative to the negative,
then recharge in the standard fashion.
4. A boost charge is only for emergencies. It will partially charges
the battery at a high rate and in a short time.
When using a boost-charged battery, it is necessary to recharge
the battery as early as possible.
Failure to do this will shorten the battery's service life.
5. When the specific gravity of electrolyte (3) become between
1.27 and 1.29 charge has completed.
6. When exchanging an old battery into new one, use battery of
equal specification shown in "SPECIFICATIONS".
