If the electrolyte is below the maximum level line,
add distilled water using the following procedure.
See “Removing Machinery Cover” on page 5-14
and remove the machinery cover.
WARNING! Fire Hazard. Do not fill the battery
with electrolyte above the maximum level line.
1. Remove all battery caps (3) and refill with
distilled water to the maximum level line.
2. Check the ventilation holes of the battery
caps. Clean the caps, then install and
securely tighten.
3. Clean the battery. Using water, wipe with a

Battery Charging
WARNING! The following safety messages
address a potential Explosion and Fire
Hazard:
• Batteries produce flammable hydrogen gas
when charging. Do not smoke near a battery
and never expose the battery to fire or
sources of high heat.
Fig. 5-100
• Excessive charging current or
over-charging may cause battery fluid leaks.
• Always remove the battery cables from the
battery or remove the battery from the
machine before charging the battery.
• Never charge a frozen battery. See “COLD
TEMPERATURE PREPARATION” on page
5-72.
• Always charge the battery in a
well-ventilated area.
• Remove all the battery caps to release
hydrogen gas while charging.
• Never use excessive charging voltage
settings.
NOTICE:
• Always keep the battery fully charged to
lengthen battery life.
• During high ambient temperatures, check the
electrolyte level frequently in addition to its
regular maintenance intervals.
• The battery should not be charged quickly after
being discharged. Measure the specific gravity
of the battery fluid in advance and charge the
battery slowly as needed.
