10. Use a gapping tool to gently bend the side
electrode closer to or farther from the center
electrode to set the correct gap. See Figure 4 -10.
Position the side electrode directly over the center
electrode.

11. Reinstall the spark plug. Do not bump the
electrode against the cylinder head. Rotate the
spark plug clockwise until you feel resistance.
12. Use a torque wrench to torque each spark plug to
25 Nm (18 ft. lbs.). Otherwise, hand-tighten the
spark plug until you feel resistance.
13. Use a ratchet wrench to final tighten an additional
1/4 turn. Do not overtighten, as doing so may strip
the threads or alter the electrode gap setting.
14. Check the spark plug wire connector in the boot for
accumulated dirt, grease, and other debris, and
clean as necessary.
15. Firmly push the spark plug boot onto the spark
plug.
16. Reconnect the generator set engine starting
battery, negative (--) lead last.
17. Reconnect the power for the battery charger.
4.8 Battery
Consult the battery manufacturer’s instructions
regarding battery care and maintenance.
Sulfuric acid in batteries.
Can cause severe injury or death.
Wear protective goggles and
clothing. Battery acid may cause
blindness and burn skin.
WARNING
Battery electrolyte is a diluted sulfuric acid. Battery acid
can cause severe injury or death. Battery acid can cause
blindness and burn skin. Always wear splashproof safety
goggles, rubber gloves, and boots when servicing the battery.
Do not open a sealed battery or mutilate the battery case. If
battery acid splashes in the eyes or o n the skin, immediately
flush the affected area for 15 minutes with large quantities of
clean water. Seek immediate medical aid in the case of eye
contact. Never add acidto a batteryafter placingthe battery in
service, as this may result in hazardous spattering of battery
acid.
Battery acid c leanup. Battery acid can cause severe
injury or death. Battery acid is electrically conductive and
corrosive. Add 500 g (1 lb.) of bicarbonate of soda (baking
soda) to a container with4L(1gal.)ofwaterandmixthe
neutralizing solution. Pour the neutralizing solution on the
spilled battery acid and continue to add the neutralizing
solution to the spilled battery acid until all evidence of a
chemical reaction (foaming) has ceased. Flush the resulting
liquid with water and dry the area.
Battery gases. Explosion can cause severe injury or
death. Battery gases can cause an explosion. Do not smoke
or permit flames or sparks to occur near a battery at any time,
particularly whenit is charging. Donot disposeof abattery in a
fire. To prevent burns and sparks that could cause an
explosion, avoid touching the battery terminals with tools or
other metal objects. Remove all jewelry before servicing the
equipment. Discharge static electricity from your body before
touching batteries by first touching a grounded metal surface
away from the battery. To avoid sparks, do not disturb the
battery charger connections while the battery is charging.
Always turn the battery charger off before disconnecting the
battery connections. Ventilate the compartments containing
batteries to prevent accumulation of explosive gases.
