Do not dispose of the battery in a fire. The
battery is capable of exploding.
A battery presents a risk of electrical shock
and high short circuit current. The following
precautions are to be observed when work-
ing on batteries:
H Remove the 7.5A fuse from the generator con-
trol panel.
H Remove watches, rings or other metal objects.
H Use tools with insulated handles.
H Wear rubber gloves and boots.
H Do not lay tools or metal parts on top of the
battery.
H Disconnect charging source prior to connecting
or disconnecting battery terminals.
n
Do not open or mutilate the battery.
Released electrolyte has been known to
be harmful to the skin and eyes, and to be
toxic.
n
The electrolyte is a dilute sulfuric acid that
is harmful to the skin and eyes. It is electri-
cally conductive and corrosive. The follow-
ing procedures are to be observed:
H Wear full eye protection and protective clothing.
H Where electrolyte contacts the skin, wash it off
immediately with water.
H Where electrolyte contacts the eyes, flush thor-
oughly and immediately with water and seek
medical attention.
H Spilled electrolyte is to be washed down with
an acid neutralizing agent. A common practice
is to use a solution of 1 pound (500 grams)
bicarbonate of soda to 1 gallon (4 liters) of
water. The bicarbonate of soda solution is to
be added until the evidence of reaction (foam-
ing) has ceased. The resulting liquid is to be
flushed with water and the area dried.
Lead-acid batteries present a risk of fire
because they generate hydrogen gas. The
following procedures are to be followed:
H DO NOT SMOKE when near the battery.
H DO NOT cause flame or spark in battery area.
H Discharge static electricity from body before
touching the battery by first touching a ground-
ed metal surface.
n
Be sure the AUTO/OFF/MANUAL switch is
set to the OFF position before connecting
the battery cables. If the switch is set to
AUTO or MANUAL, the generator can crank
and start as soon as the battery cables are
connected.
Be sure the utility power supply is turned off
and the 7.5A fuse is removed from the gener-
ator control panel, or sparking may occur at
the battery posts as the cables are attached
and cause an explosion.
4.7 ADJUSTING GT-530 VALVE
CLEARANCE
After the first six (6) months of operation or 500 hours of
operation, check the valve clearance in the engine, adjust if
necessary.
