Before Starting The Engine

Read "Operator Safety Rules" section prior to using this product.

CAUTION

This engine was shipped from the factory without oil. If you start the engine without oil, the engine will be damaged beyond repair and will not be covered under warranty.

Oil Capacity

The engine holds approximately 20 ounces (0.6 liter)

of oil.

Oil Recommendation

Choose a viscosity from the following chart.

SAE 30 40°F and higher (5°0 and higher)

is good for all purpose use above 40°F, use below 40°F will cause hard starting.

10W-30 0 to IO0_F (- 18 to 38c'C) is better for varying temperature conditions. This grade of oil improves cold weather starting, but may increase oil consumption at 80°F (27°C) or higher.

Check oil level frequently at higher temperatures.

Synthetic 5W-30 -20 to 120_'F (-30 to 40_C) provides the best protection at all temperatures as well as improved starting with less oil consumption.

5W-30 40_F and below (5°C and below) is recommended for winter use, and works best in cold conditions.

Always wear safety glasses. If you wear eye glasses, put a Wide Vision Safety Mask over your eye glasses.

WARNING

• Always wear safety glasses or eye shields while you assemble, operate or do maintenance to

the unit.

Gasoline Requirements

All gasoline is not the same. If a starting or

performance problem is encountered after new gasoline has been used, try another service station or change brands.

This engine is designed to operate on gasoline. The

emission control system for this engine is EM (Engine Modifications).

Type of gasoline to use Always use gasoline that meets these requirements:

• Clean, fresh, unleaded gasoline.

• A minimun of 87 octane/87 AKI (91 RON). At altitudes over 5,000 feet, see "High-altitude use".

• Gasoline with up to 10% ethanol (gasohol) or up

to 15% MTBE (methyl tertiary butyl ether), is

acceptable.

• Use of any gasoline other than those approved above will void the engine warranty. Some areas require that fuel pumps be marked if the gasoline contains alcohols or ethers. If you are not sure if your gasoline contains alcohol or ethers that are different than those approved above, then

check with the service station operator.

• Do not modify the engine fuel system or carburetor to run on alternative fuels.

• Never mix oil with gasoline.

Gasoline Storage

Follow these guidelines when storing gasoline for longer than 30 days:

• If fuel stabilizer is used, you do not need to drain gasoline prior to storage.

• If no fuel stabilizer is used, then always remove gasoline from engine during storage.

Fuel stabilizer

• If you do not want to remove the gasoline, add a

fuel stabilizer to any gasoline left in the fuel tank. A fuel stabilizer will minimize gum deposits and acids.

If the fuel tank is almost empty, mix the fuel stabilizer with fresh gasoline in a separate

container and add the mixture to the fuel tank.

Always follow the instructions on the stabilizer

container. Start the engine. Let the engine run for 3 minutes to allow the mixture to reach the

carburetor.

High-altitude use

At higher altitudes (over 5,000 feet), 85 octane / 85 AKI (89 RON) gasoline can be used. Operation at high altitude may require a high-altitude carburetor jet kit to improve performance and decrease fuel consumption.

Adding Fuel

1 Stop the engine. Before you remove gas cap (A),

let the engine cool at least 2 minutes.

2 Remove the gas cap. Fill the fuel tank (B) to

approximately 1-1/2 inches below top of neck to allow for fuel expansion. Be careful, do not overfill.

How To Operate The Edger

The edger is designed to cut a small trench along

sidewalks and driveways or to trim close to trees,

flower beds, lampposts, etc. The main reason for

edging is to enhance the overall appeal of the yard. A cleanly-edged yard gives a nice, overall finished look.

Always dress properly to protect against flying debris. Wear substantial shoes, long pants and close-fitting

clothes that are not likely to get caught in the machinery. Also, make sure to wear safety glasses or goggles.

WARNING

• Always wear safety glasses or eye shields while you assemble, operate or do maintenance to

the unit.

To reduce the risk of flying debris, inspect the area

and remove any stones, sticks or other objects that could be thrown by the edger.

3 Start the engine. See "How To Start The Engine".

4 Move the depth control lever back to lower the

blade. Do not try to edge too deep. It may take

several passes to obtain a nice clean edge.

burned or worn. Make sure that the spark plug is clean. Check the gap with a wire gauge (B). If

necessary, reset to 0.030" (0.76 mm). See (Figure 17).

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 same type for replacement.

How To Change The Oil

Change oil after first 5 to 8 hours of use, then every 50 hours. Change oil every 25 hours when operating the engine under heavy load or in high

temperatures.

1 Make sure the engine is level. 2 Disconnect the spark plug wire and keep it away

from the spark plug.

3 With engine off but still warm, remove the oil drain

plug (A) as shown in Figure 18. Drain the oil into an appropriate receptacle.

Figure 18: Oil Drain Plug

8 To add oil, pour the oil slowly into the engine oil fill.

The engine holds approximately 20 ounces (0.6

liter) of oil. For the type of oil to use, see "Oil Recommendation" in the Operation Section.

9 Before checking the oil level, wait 2 minutes for the

oil to drain out of the oil fill. Then, install the dipstick and check the oil level. Make sure the oil

is at the FULL mark shown on the dipstick (see Figure 19). Do not overfill.

10 Connect the spark plug wire to the spark plug.

4 After draining all the oil, install and tighten the oil

drain plug.

5 Make sure the engine is level. 6 Clean the engine oil fill area of debris. 7 Remove the dipstick (B) from the engine oil fill (C).

Wipe the dipstick with a clean cloth.
