NOTE: Allow spilled fuel to evaporate before starting unit.

It is important to prevent gum deposits from forming in fuel system parts such as the carburetor, fuel hose or tank during storage. Alcohol-blended fuels (called gasohol, ethanol or methanol) can attract moisture, which leads to separation and formation of acids during storage. Acidic gas can damage the fuel system of an engine while in storage. To avoid engine problems, the fuel system should be emptied before storage of 30 days or longer. See the Storage section. Never use engine or carburetor cleaner products in the fuel tank as permanent damage may occur.

Before Starting Engine

1. Verify engine oil level is correct.
2. Verify fuel level is correct.
3. Verify unit is secure on level ground, with proper clearance and is in a well ventilated area.

Prepare Generator for Use

Asphyxiation. Running engines produce carbon monoxide, a colorless, odorless, poisonous gas. Carbon monoxide, if not avoided, will result in death or serious injury.

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.

Asphyxiation. Always use a battery operated carbon monoxide alarm indoors and installed according to the manufacturer's instructions. Failure to do so could result in death or serious injury.

Risk of fire. Do not use generator without spark arrestor installed. Failure to do so could result in death or serious injury.

Risk of Fire. Hot surfaces could ignite combustibles, resulting in fire. Fire could result in death or serious injury.

Hot Surfaces. When operating machine, do not touch hot surfaces. Keep machine away from combustibles during use. Hot surfaces could result in severe burns or fire.

Equipment and property damage. Disconnect electrical loads prior to starting or stopping unit. Failure to do so could result in equipment and property damage.

Grounding the Generator When Used as a Portable

The generator is equipped with a terminal for the connection of a grounding electrode system. Article 250.34 (A) does not require the frame of the generator to be connected to a grounding electrode system when the generator only supplies power to cord and plug connected equipment through the receptacles on the generator.

When the generator supplies power to a 3-pole manual transfer switch or distribution panel boards for temporary power, a grounding electrode system shall be installed and connected to the grounding electrode terminal on the generator. See NEC 250.30, 250.34 and 250.52 for clarification. See Figure 3-1

• Neutral Bonded to Fram
  
  Figure 3-1 . Grounding the Generator

Special Requirements

Review all Federal or State Occupational Safety and Health Administration (OSHA) regulations, local codes, or ordinances that apply to the intended use of the generator.

Consult a qualified electrician, electrical inspector, or the local agency having jurisdiction:

• In some areas, generators are required to be registered with local utility companies.
• If the generator is used at a construction site, there may be additional regulations which must be observed.

Connecting the Generator to a Building Electrical System

When connecting directly to a building electrical system, it is recommended that a manual transfer switch be used. Connections for a portable generator to a building electrical system must be made by a qualified electrician and in strict compliance with all national and local electrical codes and laws.

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 generator'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 selecting electrical devices to connect to the generator:

1. Figure the watts needed to start the largest motor.
2. Add to that figure the running watts of all other connected loads.

The Wattage Reference Guide is provided to assist in determining how many items the generator can operate at one time.

NOTE: All figures are approximate. See data label on appliance for wattage requirements.

Automatic Idle Control

This feature will improve fuel economy. When the switch is turned On, the engine will only run at its normal fast governed engine speed when electrical load is connected. When load is removed, the engine will run at a reduced speed. With the switch Off, the engine runs continuously at normal fast engine speed.
Always have the switch Off when starting and stopping the engine.

Cold Weather Operation/De-icer

Under certain weather conditions (temperatures below 40°F (4°C) and a high dew point), the engine may experience icing of the carburetor and/or the crankcase breather system. To eliminate this problem, the generator engine is fitted with a winter/summer valve.
This directs hot air into the carburetor during cold weather operation. Always make sure the winter/summer valve is in the correct location relative to weather condition.

Low Oil Level Shutdown System

The engine is equipped with a low oil pressure sensor that shuts down the engine automatically when the oil pressure drops below a specified level. The engine will not run until the oil has been filled to the proper level.
If the engine shuts down and there is sufficient fuel, check engine oil level.

Using the 12 VDC Battery Charger

Explosion. Batteries emit explosive gases while charging. Keep fire and spark away. Wear protective gear when working with batteries. Failure to do so could result in death or serious injury.

Risk of burn. Do not open or mutilate batteries. Batteries contain electrolyte solution which can cause burns and blindness. If electrolyte contacts skin or eyes, flush with water and seek immediate medical attention.

Risk of burns. Batteries contain sulfuric acid and can cause severe chemical burns. Wear protective gear when working with batteries. Failure to do so could result in death or serious injury.

Equipment damage. Do not make battery connections in reverse. Doing so will result in equipment damage.

The 12 VDC receptacle may be used to recharge 12 VDC automotive batteries only. The DC charging output is not regulated. The circuit protector does not prevent overcharging a battery.

1. Connect the charging cable to the generator first, then the battery. ALWAYS connect the red lead to positive (+), and the black to negative (-).
2. Start generator and use as normal. Charging time will vary with battery size and condition. Check voltage at battery terminals once the charging cable has been unplugged, or generator has been shut down.

NOTE: This receptacle cannot recharge 6 Volt batteries and cannot be used to crank an engine having a discharged battery.

NOTE: Call 1-888-GENERAC (1-888-4363722) with questions about component replacement.

Maintenance Schedule

Follow maintenance schedule intervals, whichever occurs first according to use.

NOTE: Adverse conditions will require more frequent service.

NOTE: All required service and adjustments should be each season as detailed in the following chart.

At Each Use: Check engine oil level

Every 100 Hours or Every Year: Inspect/clean spark arrestor

Every 200 Hours or Every Year:

• Replace spark plug
• Replace fuel filter
• Change oil ǂ
• Inspect/clean air filter**
• Check valve clearance***

ǂ Change oil after first 25 hours of operation, then every season.
* Change oil and oil filter every month when operating under heavy load or in high temperatures.
** Clean more often under dirty or dusty operating conditions. Replace air filter parts if they cannot be adequately cleaned.
*** Check valve clearance and adjust if necessary after first 50 hours of operation and every 200 hours thereafter.

Preventive Maintenance

Dirt or debris can cause improper operation and equipment damage. Clean generator daily or before each use. Keep area around and behind muffler free from combustible debris. Inspect all cooling air openings on generator.

Personal injury. Do not insert any object through the air cooling slots. Generator can start at any time and could result in death, serious injury, and unit damage.

• Use a damp cloth to wipe exterior surfaces clean.
• Use a soft bristle brush to loosen caked on dirt, oil, etc.
• Use a vacuum to pick up loose dirt and debris.
• Low pressure air (not to exceed 25 psi) may be used to blow away dirt. Inspect cooling air slots and openings on generator. These openings must be kept clean and unobstructed.

NOTE: DO NOT use a garden hose to clean generator. Water can enter engine fuel system and cause problems. If water enters generator through cooling air slots, some water will be retained in voids and crevices of rotor and stator winding insulation. Water and dirt buildup on generator internal windings will decrease insulation resistance of windings.
