BATTERY MAINTENANCE
The battery should be inspected per the "Service Schedule" sec-
tion. The following procedure should be followed for inspection:
1.
Inspect the battery posts and cables for corrosion and tight-
ness. Clean and tighten as necessary.
2.
Check the battery fluid level of unsealed batteries and, if nec-
essary, fill with Distilled Water Only. Do not use tap water in
batteries.
3.
Have the state of charge and condition checked. This should
be done with an automotive-type battery hydrometer.
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:
• Remove the 7.5A fuse from the generator con-
trol panel.
• Remove watches, rings or other metal objects.
• Use tools with insulated handles.
• Wear rubber gloves and boots.
• Do not lay tools or metal parts on top of the
battery.
• Disconnect charging source prior to connecting
or disconnecting battery terminals.
Do not open or mutilate the battery.
Released electrolyte has been known to
be harmful to the skin and eyes, and to be
toxic.
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:
• Wear full eye protection and protective clothing.
• If electrolyte contacts the skin, wash it off
immediately with water.
• If electrolyte contacts the eyes, flush thorough-
ly and immediately with water and seek medical
attention.
• 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 (baking soda)
solution is to be added until the evidence of
reaction (foaming) 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:
• DO NOT SMOKE when near the battery.
• DO NOT cause flame or spark in battery area.
• Discharge static electricity from body before
touching the battery by first touching a ground-
ed metal surface.
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.

ADJUSTING OHV-432 VALVE
CLEARANCE
After the first six (6) months of operation, check the valve clear-
ance in the engine, adjust if necessary.
Important: If feeling uncomfortable about doing this procedure
or the proper tools are not available, please contact the Dealer for
service assistance. This is a very important step to ensure longest
life for the engine.
To check valve clearance:
•
The engine should be cool before checking. If valve clearance is
0.006" - 0.008" (0.15 - 0.20mm), adjustment is not needed.
•
Remove spark plug wire and position wire away from plug.
•
Remove spark plug.
•
Make sure the piston is at Top Dead Center (TDC) of its com-
pression stroke (both valves closed). To get the piston at TDC,
remove the intake screen at the top of the engine to gain access
to the flywheel nut. Use a large socket and socket wrench to
rotate the nut and hence the engine in a clockwise direction.
While watching the piston through the spark plug hole. The
piston should move up and down. The piston is at TDC when it
is at its highest point of travel.
