Off/Run/Choke Switch This controls the ON/OFF functions, choke and fuel valve operation. See Figure 2-5.

• The OFF position (1) stops the engine and shuts off fuel flow.

• The RUN position (2) is for normal opera- tion and to gradually reduce the use of the choke.

• The CHOKE position (3) switches the fuel valve on to start the engine. NOTE: The CHOKE is not required to start a warm engine. Figure 2-5. Switch (example) USB Outlets The 5 VDC, 1/2.1 Amp USB outlet allows charging of compatible electronic devices. Economy Switch The economy switch has 2 modes of opera- tion:

• On: The quietest mode and best when run- ning appliances or equipment that are resistive loads (non-motor starting), (exam- ple: TV, video game, light, radio).

• Off: Best when running a both inductive (motor-starting) and resistive (non-motor starting) loads, especially when these loads are turning on and off (example: RV, air conditioner, hairdryer). Generator Status Lights See Figure 2-6.

• Overload LED (red): Indicates system overload (2). During motor starting it is nor- mal for the overload LED to illuminate for a few seconds. If LED stays illuminated and the ready LED turns off, the engine will con- tinue to run without output power. Remove all applied loads and determine if attached devices exceed recommended output power. Check for faulty or shorted connec- tions. To restore electrical output, turn dial OFF to reset. Start engine. If condition was corrected, the orange LED will not illumi- nate and electrical output will be restored. Loads can be applied once the green LED illuminates.

Prepare Generator for Use Grounding the Generator When In Use The generator is equipped with an equipment ground connecting the generator frame and the ground terminals on the AC output recep- tacles (see NEC 250.34 (A). This allows the generator to be used as a portable without grounding the frame of the generator as spec- ified in NEC 250.34. See Figure 3-1.

• Neutral Floating Figure 3-1.Grounding the Generator The generator (stator winding) is isolated from the frame and from the AC receptacle ground pin. Electrical devices that require a grounded receptacle pin connection will not function if the receptacle ground pin is not functional. Know Generator Limits Overloading a generator can result in damage to the generator and connected electrical devices. Observe the following to prevent overload:

• Add up the total wattage of all electrical devices to be connected at one time. This total should NOT be greater than the gener- ator's wattage capacity.

• The rated wattage of lights can be taken from light bulbs. The rated wattage of tools, appliances, and motors can be found on a data label or decal affixed to the device.

• If the appliance, tool, or motor does not give wattage, multiply volts times ampere rating to determine watts (volts x amps = watts).

• Some electric motors, such as induction types, require about three times more watts of power for starting than for running. This surge of power lasts only a few seconds when starting such motors. Make sure to allow for high starting wattage when select- ing electrical devices to connect to the gen- erator:

1. Figure the watts needed to start the largest

2. Add to that figure the running watts of all

other connected loads. Asphyxiation. Running engines produce carbon monoxide, a colorless, odorless, poisonous gas. Carbon monoxide, if not avoided, will result in death or serious injury.(000103) DANGER (000179b)DANGER Asphyxiation. The exhaust system must be properly maintained. Do not alter or modify the exhaust system as to render it unsafe or make it noncompliant with local codes and/or standards. Failure to do so will result in death or serious injury.

Proper valve clearance is essential for prolonging the life of the engine. Check valve clearance after the first fifty-hours of operation. Adjust as necessary.

• Intake — 0.10 ± 0.02mm (cold), (0.004" ± 0.001" inches)

• Exhaust — 0.10 ± 0.02mm (cold) (0.004" ± 0.001" inches) Storage General It is recommended to start and run the genera- tor for 30 minutes, every 30 days. If this is not possible, refer to the following list to prepare unit for storage.

• DO NOT place a storage cover on a hot generator. Allow unit to cool to room tem- perature before storage.

• DO NOT store fuel from one season to another unless properly treated.

• Replace fuel container if rust is present. Rust in fuel will cause fuel system prob- lems.

• Cover unit with a suitable protective, mois- ture resistant cover.

• Store unit in a clean, dry area.

• Always store generator and fuel away from heat and ignition sources. Prepare Fuel System/Engine for Storage Fuel stored over 30 days can go bad and damage fuel system components. Keep fuel fresh, use fuel stabilizer. If fuel stabilizer is added to fuel system, pre- pare and run engine for long term storage. Run engine for 10-15 minutes to circulate sta- bilizer throughout fuel system. Adequately prepared fuel can be stored up to 24 months. NOTE: If fuel has not been treated with fuel stabilizer, it must be drained into an approved container. Run engine until it stops from lack of fuel. Use of fuel stabilizer in fuel storage container is recommended to keep fuel fresh.
