2. Turn Engine switch (F) to the OFF position.
3. Turn Fuel cock (I) to the OFF position.

Troubleshooting

Engine will not start Out of fuel

• If engine is cold, ensure choke lever is set correctly.
• Add fuel

Engine flooded

• Set choke lever to open/run position

Fouled spark plug/engine fails to product spark

• Remove spark plug and clean it. Check the spacing on the electrode and set the gap to the correct dimension. See Maintenance Section. If plug is damaged, replace with a new spark plug.
• Ensure the spark plug is installed and wire is connected.

Electric starting

• (It is optional) Check battery capacity and Fuse is burnt out or not.
  Warning:

• Do not crank engine with spark plug removed.

Oil

Oil Recommendations

• We recommend the use of our Warranty Certified oils for best performance. Other high-quality detergent oils are acceptable if classified for service SF, SG, SH. SJ or higher.
• Do not use special additives.
• Outdoor temperatures determine the proper oil viscosity for the engine. Use the chart to select the best viscosity for the outdoor temperature range expected.

Note: Below 40 F° (4 °C) the use of SAE 30 will result in hard starting. Above 80 F (2°7 C) °the use of 10W-30 may cause increased oil consumption. Check oil level more frequently.

Before adding or checking the oil

• Place engine level.
• Clean the oil fill area of any debris.

How to Check/Add Oil

1. Remove the dipstick (O) and swipe with a clean cloth (Figure 1).
2. Insert the dipstick into the filler neck without screwing it in.
3. Remove the dipstick and check the oil level. Make sure the oil is at the FULL mark (B) on the dipstick.
4. To add oil, pour the oil slowly into the engine oil fill (A). Do not overfill. After adding oil, wait one minute and then recheck the oil level.
5. Replace and tighten the dipstick.

Fuel Recommendations
Fuel must meet these requirements:

• Clean, fresh, unleaded gasoline.
• A minimum of 87 octane/87 AKI (91 RON). High altitude use, see below.
• Gasoline with up to 10% ethanol (gasohol) or up to 15% MTBE (methyl tertiary butyl ether) is acceptable.

CAUTION: Do not use unapproved Gasoline, such as E85. Do not mix oil in gasoline or modify the
engine to run on alternate fuels. This will damage the engine components and void the engine warranty. To protect the fuel system from gum formation, mix a fuel stabilizer into the fuel. See Storage. All fuel is not the same. This engine is certified to operate on gasoline. The emissions control system for this engine is EM (Engine Modifications).

High Attitude Operation
Your engine is configured for operation below 2,000 feet altitude at the factory. Your engine must be reconfigured for operation above 2,000 feet altitude. Operating the engine with the wrong engine configuration at a given altitude may increase its emissions, decrease fuel efficiency, degrade per- formance, and cause irreversible damage. Engines configured for high altitude operation cannot be operated in standard altitude conditions. A qualified service center should ensure that your engine is properly configured for your location.

How to Add Fuel

• Turn engine off and let engine cool at least 2 minutes before removing the fuel cap.
• Fill fuel tank outdoors or in well-ventilated area.
• Do not overfill fuel tank. Fill tank to approximately 1.5 inches (38 mm) below top of neck to allow for fuel expansion.
• Keep gasoline away from sparks, open flames, pilot lights, heat, and other ignition sources.
• Check fuel lines, tank, cap, and fittings frequently for cracks or leaks. Replace if necessary.
• If fuel spill, wait until it evaporates before starting engine.

1. Clean the fuel cap area of dirt and debris. Remove the fuel cap.
2. Fill the fuel tank with gasoline. To allow for expansion of the gasoline, do not fill above the bottom of the fuel tank neck. 3. Reinstall the fuel cap.

Maintenance

Use only original equipment replacement parts. Other parts may not perform as well, may damage the unit, and may result in injury. In addition, use of other parts may void your warranty. We recommend that you see any ours’ for all maintenance and service of the engine and engine parts.

CAUTION: All the components used to build this engine must remain in place for proper operation.

Before performing adjustments or repairs:

• Disconnect the spark plug wire and keep it away from the spark plug.
• Use only correct tools.
• Do not tamper with governor spring, links or other parts to increase engine speed.
• Replacement parts must be the same and installed in the same position as the original parts.
• Do not strike the flywheel with a hammer or hard object because the flywheel may later shatter during operation.

When testing for spark:

• Use approved spark plug tester.
• Do not choke for spark with spark plug removed.

Maintenance Chart

Carburettor Adjustment
Never make adjustments to the carburetor. The carburetor was set at the factory to operate efficiently under most conditions. However, if adjustments are required, see any our Authorized Dealer for service.

CAUTION: The manufacturer of the equipment on which this engine is installed specifies the top speed at which the engine will be operated. Do not exceed this speed.

How to Replace the Spark Plug

Check the gap (A) with a wire gauge (B). If necessary, reset the gap. Install and tighten the spark plug to the recommended torque. For gap setting or torque, see the Specifications section. Note: In some areas, local law requires using a resistor spark plug to suppress ignition signals. If this engine was originally equipped with a resistor spark plug, use the same type for replacement.

Inspect Muffler and Spark Arrester (if applicable)

• Allow muffler, engine cylinder and fins to cool before touching.
• Remove accumulated debris from muffler area and cylinder area.

WARNING: Replacement parts must be the same and installed in the same position as the original parts or fire could result.

How to Service the Air Filter (see figure 2)

1. Remove the air cleaner outside cover (A). Be careful to prevent dirt and debris from falling into the air cleaner assembly.
2. Separate the Air Filter (A) from the Air Filter Housing (B).
3. Inspect the air filter. Clean dirty air filter with warm water and mild soap. Allow air filter to dry thoroughly before re-installation
4. Install the air filter assembly onto the carburetor and secure with screw.

Note: Do not use pressurized air or solvents to clean the filter. Pressurized air can damage the filter and solvents will dissolve the filter.

How to Remove Oil
Caution: Used oil is a hazardous waste product and must be disposed of properly. Do not discard with household waste. Check with your local authorities, service center, or dealer for safe disposal/recycling facilities.

Removing Oil
The oil must be drained from the Oil Drain Plug (See figure 3)

1. Remove the dipstick (C)
2. Please an approved container below the oil drain plug.
3. Remove the Oil drain plug (D) and allow oil to the drain into the approved container.
4. Install Oil drain plug (D) and wrench tighten.

WARNING: When you drain the oil from the oil drain plug, the fuel tank must be empty or fuel can leak out and result in fire or explosion. To empty the fuel tank, run engine until it stops from lack of fuel.

How to Service the Battery -see figure 4 (if applicable)
WARNING: Be careful not to connect the battery in reverse polarity, as this will short circuit the battery charging system.

Note: Use a 12-volt battery with an ampere-hour rating of at least 18 Ah.

1. Connect the positive (+) cable to the starter solenoid terminal.
2. Connect the negative (-) cable to an engine mounting bolt or other good engine ground connection.
3. Connect the positive (+) cable to the positive (+) terminal.
4. Connect the negative (-) cable to the negative (-) terminal. 5.
5. Coat terminals and cable ends with grease.
