PREPARATION FOR FIRST OPERATION

CAUTION:
3
To avoid personal injury:
¡ To avoid personal injury from
contact with moving parts;
¡ N e v e r o p e n t h e d o o r o r
generator side cover while the
engine is running.
¡ D O N O T t o u c h m u f f l e r o r
exhaust pipes while they are
hot; Severe burns could result.
a How to Open the Door
Open the machine door and hold it open with the
door rod q.
(1) Door rod
a Battery
The battery is shipped in dry, charged condition
without electrolyte.
The battery must be charged properly before using
for the first time.
DANGER:
3
To avoid the possibility of battery
explosion:
The battery comes in two types:
refillable and non-refillable. For using
the refillable type battery, follow the
instructions below.
¡ DO NOT use or charge the battery if
the fluid level stands below the
LOWER (lower limit level) mark.
Otherwise, the battery component
parts may get deteriorated earlier
than expected, which may shorten
the battery's service life or cause an
explosion.
Immediately, add distilled water
until the battery's fluid level comes
somewhere between the UPPER
and LOWER levels.
PREPARATION FOR FIRST OPERATION
¡ Keep all sparks and flames away
from the battery and fuel tank. A
battery, especially when charging,
will give off hydrogen and oxygen
gases which can explode and
cause serious personal injury.
1. Remove the vent plugs.
2. Fill cells up to the upper level with electrolyte.
[Specific gravity of sulfuric acid 1.270 to 1.290 (at
20°C=68°F)]
3. Allow the battery to sit for about one hour after filling.
4. If the electrolyte level is dropped, refill with electrolyte
up to the upper level.
5. Charge the battery at the normal charging current of
6.0 amperes.
6. Replace the vent plugs, and wash off any electrolyte
which may have spilled.
(1) Vent plug opening
(2) Electrolyte level indication tube
(3) Indicated level
NOTE:
¡ The duration of dry charged efficiency, will decrease
in proportion to the period of time elapsed after
shipment and during storage. To obtain the longest
service life of the battery, it is necessary for the
battery to be charged for a sufficient period of time.
Continue to charge until all cells are gassing freely,
and the voltage and specific gravity reading in all
cells remain constant for 3 or more successive
readings taken at 30 minute intervals.
¡ When the battery has been charged fully, the
specific gravity of electrolyte should be 1.270 to
1.290 (at 20˚C = 68˚F).
