Connection

WARNING Before the generator can be connected to a build- ings electrical system, a licensed electrician must install an isolation (transfer) switch in the build- ings main fuse box. The switch is the connection point for generator power and allows selection of generator or main line power to the building. This will prevent the generator from charging the main power line (backfeeding) when the main power supply has failed or has been turned off for line repair. Backfeeding can electrocute or injure line maintenance personnel. Also, generator and build- ing electrical system damage can occur when nor- mal operating power returns if unit is used without an isolation switch.

AE00086

Extension cord notes Extension cords should be protected by a tough flexi- ble rubber sheath (IEC 245) or the equivalent to with- stand mechanical stresses.

NOTICE

9 Be sure to connect the red battery charger lead to the positive (+) battery terminal, and connect the black lead to the negative () bat- tery terminal. Do not reverse these positions.

9 Connect the battery charger leads to the bat- tery terminals securely so that they are not disconnected due to engine vibration or other disturbances.

9 Charge the battery in the correct procedure by following instructions in the owners manual for the battery.

9 The DC protector turns off automatically if cur- rent above the rated flows during battery charging.

To restart charging the battery, turn the DC protector on by pressing its button to (ON). If the DC protector turns off again, stop charg- ing the battery immediately and consult a Yamaha dealer.

TIP 9 Follow instructions in the owners manual for the

battery to determine the end of battery charging. 9 Measure the specific gravity of electrolyte to

determine if the battery is fully charged. At full charge, the electrolyte specific gravity is between 1.26 and 1.28.

9 It is advisable to check the specific gravity of the electrolyte at least once every hour to prevent overcharging the battery.

Operating range of DC power supply (exclusively for charging 12 V battery) This power source is designed to charge batteries up to 40 Ah that are half-discharged. Do not charge bat- teries of a higher capacity than 40 Ah. 12 V battery The time required for recharging a battery varies depending on the discharge level of the battery. When the specific gravity of the battery reaches 1.26 to 1.28, charging is complete. When charging, check the bat- terys specific gravity once an hour. The average time for charging a half-discharged 40 Ah battery is approximately 5 hours. Be sure to check the battery fluid level before charging.

NOTICE

9 Do not connect any load to the battery or use the engine starter motor while charging. This causes high current to flow through the gener- ator which will burn out the coil.

9 Do not connect a VRLA (Valve Regulated Lead Acid) battery. To charge a VRLA battery, a spe- cial (constant-voltage) battery charger is required.

WARNING 9 Electrolyte is poisonous and dangerous since

it contains sulfuric acid, which causes severe burns. Avoid any contact with skin, eyes or clothing and always shield your eyes when working near batteries. In case of contact, administer the following FIRST AID.

9 EXTERNAL: Flush with plenty of water. 9 INTERNAL: Drink large quantities of water or

milk and immediately call a physician. 9 EYES: Flush with water for 15 minutes and

seek prompt medical attention. 9 Batteries produce explosive hydrogen gas.

Therefore, keep sparks, flames, cigarettes, etc., away from the battery and provide sufficient ventilation when charging it in an enclosed space.

9 KEEP THIS AND ALL BATTERIES OUT OF THE REACH OF CHILDREN.

1 Side cover screw 2 Side cover

2. Remove the spark plug cap and the spark plug.

3 Spark plug cap

3. Check for discoloration and remove the carbon. The porcelain insulator around the center elec-

trode of spark plug should be a medium-to-light tan color.

4. Check the spark plug type and gap.

a Spark plug gap

Standard spark plug: BPR4ES (NGK) Spark plug gap: 0.70.8 mm (0.0280.031 in)

TIP The spark plug gap should be measured with a wire thickness gauge and, if necessary, adjusted to specifi- cation.

5. Install the spark plug.

Spark plug tightening torque: 20 Nm (2.0 mkgf, 14 ftlbf)

TIP If a torque wrench is not available when installing a spark plug, a good estimate of the correct torque is 1/4-1/2 turn past finger tight. However, the spark plug should be tightened to the specified torque as soon as possible.

6. Install the spark plug cap.

7. Install the side cover and tighten the side cover screws.
