1. Read, understand and follow all instructions on the engine and in the manual(s) before attempting to assemble and operate. Keep this manual in a safe place for future and regular reference and for ordering replacement parts.

2. Be familiar with all controls and their proper operation. Know how to stop the engine and disengage them quickly.

3. Never allow children under 14 years of age to operate the engine. Children 14 and over should read and understand the instructions and safe operation practices in this manual and be trained and supervised by an adult.

4. Never allow adults to operate the machine without proper instruction.

5. Keep the area of operation clear of all persons, particularly small children and pets. Stop machine if anyone enters the area.

Preparation

1. Wear sturdy, rough-soled work shoes and close fitting slacks and shirts. Loose fitting clothes or jewelry can be caught in the moving parts. Never operate the machine in bare feet or sandals.

2. Disengage clutch levers and shift (if equipped) into neutral (“N”) before starting the engine.

3. Never leave the engine running while unattended.

4. Never attempt to make any adjustments while the engine is running, except where specifically recommended in the operator’s manual.

Safe Handling of Gasoline:

To avoid personal injury or property damage, use extreme care in handling gasoline. Gasoline is extremely flammable and the vapors are explosive. Serious personal injury can occur when gasoline is spilled on yourself and/or your clothes which can ignite. Wash your skin and change clothes immediately.

1. When adding fuel, turn engine OFF and let engine cool at least 2 minutes before removing the gas cap.

2. Fill fuel tank outdoors or in well ventilated area.

3. Use only an approved gasoline container.

4. Never fill containers inside a vehicle or on a truck or trailer bed with a plastic liner. Always place containers on the ground away from your vehicle before filling.

5. If possible, remove gas-powered equipment from the truck or trailer and refuel it on the ground. If this is not possible, then refuel such equipment on a trailer with a portable container, rather than from a gasoline dispenser nozzle.

6. Keep the nozzle in contact with the rim of the fuel tank or container opening at all times until fueling is complete. Do not use a nozzle lock-open device.

7. Do not overfill fuel tank. Fill tank to full as indicated by the fuel level indicator installed inside of the fuel tank or marked on the tank. Do not over-fill to allow space for fuel expansion. On some models, a fuel level indicator may NOT be present, in this instance, fill the tank no more than 1/2 inch below the bottom of the filler neck to allow space for fuel expansion.

8. Replace fuel cap and tighten until the cap ratchets.

9. If gasoline is spilled, wipe it off the engine and the equipment. Move the machine to another area. Wait five minutes before starting the engine.

10. To reduce fire hazards, keep the machine free of grass , leaves or other debris build up. Clean up oil or fuel spillage and remove any fuel-soaked debris.

11. Keep gasoline away from sparks, open flames, pilot lights, heat, and other ignition sources.

12. Never fuel equipment indoors because flammable vapors will accumulate in the area.

13. Extinguish all cigarettes, cigars, pipes, and other sources of ignition.

14. Check fuel line, tank, cap, and fittings frequently for cracks or leaks. Replace if necessary.

Operation

1. When starting the engine, make sure spark plug, muffler, and fuel cap are in place.

2. Do not crank engine with spark plug removed.

3. If fuel spills, wait until it evaporates before starting engine.

4. Allow muffler, engine cylinder, and fins to cool before touching.

5. Keep children away from hot or running engines. They can suffer burns from a hot muffler.

6. Remove accumulated combustibles from muffler and cylinder area.

7. Operate equipment with all guards in place.

8. Keep hands and feet away from rotating parts.

9. Tie up long hair and remove jewelry.

10. Do not wear loose-fitting clothing, dangling drawstrings or items that could become caught.

11. When starting the engine, pull cord slowly until resistance is felt, then pull rapidly (if not electric start).

12. Remove all external equipment/engine loads before starting engine.

13. Direct coupled equipment components such as, but not limited to blades, impellers, pulleys, sprockets, etc., must be securely attached.

Maintenance & Storage

1. Keep the engine in safe working order

2. Allow the engine to cool at least five minutes before storing. Never tamper with safety devices. Check their proper operation regularly.

3. Check bolts and screws for proper tightness at frequent intervals to keep the engine in safe working condition. Visually inspect the engine for any damage.

4. Before cleaning, repairing or inspecting; stop the engine and make certain all moving parts have stopped. Disconnect the spark plug wire and ground it against the engine to prevent unintended starting.

5. Do not change the engine governor settings or over-speed the engine. The governor controls the maximum safe operating speed of the engine.

6. Maintain and replace safety and instruction labels as necessary.

7. Always refer to the operator’s manual for important details if the machine is to be stored for an extended period of time.

8. If the fuel tank has to be drained, do this outdoors.

9. Observe proper disposal laws and regulations for gas, oil, etc. to protect the environment.

Do not modify engine

To avoid serious injury or death, do not modify engine in any way. Tampering with the governor setting can lead to a runaway engine and cause it to operate at unsafe speeds. Never tamper with factory setting of engine governor.

Notice Regarding Emissions

Engines which are certified to comply with California and federal EPA emission regulations for SORE (Small Off Road Equipment) are certified to operate on regular unleaded gasoline, and may include the following emission control systems: Engine Modification (EM), Oxidizing Catalyst (OC), Secondary Air Injection (SAI) and Three Way Catalyst (TWC) if so equipped.

Spark Arrestor

WARNING!

This machine is equipped with an internal combustion engine and should not be used on or near any unimproved for est-covered, brush covered or grass-covered land unless the engine’s exhaust s ystem is equipped with a spark ar restor meeting applicable local or s tate laws (if any).
