Filling the Fuel Tank

WARNING

• Gasoline is extremely flammable with explosive vapors. A fire or explosion from gasoline can burn you or others.
• To prevent a static charge from igniting the gasoline, place the container and/or mower directly on the ground before filling, not in a vehicle or on an object.
• Fill the tank outdoors when the engine is cold; wipe up spills.
• Do not handle gasoline while smoking or near open flame or sparks.
• Store gasoline in an approved fuel container, out of the reach of children.

Fill the fuel tank with fresh unleaded regular gasoline from a filling station. (Figure 5)

Important: To reduce starting problems, add fuel stabilizer to the fuel, mixing it with gasoline less than 30 days old. (Figure 5)

Checking the Engine Oil Level

Service Interval: Before each use.

1. Remove dipstick, wipe it clean, and fully re-insert it, check to see if oil is needed by the oil mark that is left the dipstick. (Figure 6)

2. Remove the dipstick and check the oil level (Figure 6). If the oil level is low on the dipstick, slowly pour oil into the oil fill hole to raise the oil level to the full range on the dipstick. Do not overfill. Max fill 13.5oz (0.4 L), type SAE 30 weight oil with an API service rating of SF or higher.

3. Install the dipstick and tighten the screw threads.

Cutting Height Adjustment

WARNING

• Adjusting the cutting height may bring you into contact with the moving blade, causing serious injury.
• Stop the engine and wait for all the moving parts to stop.
• Do not put your fingers under the housing when adjusting the cutting height.
• Do not exceed cutting height adjustment limited location, or it will causing serious injury or death.

WARNING

If the engine has been running, the muffler will be hot and can severely burn you. Keep away from the hot muffler.

Adjust the cutting height as desired. Set all four wheels to the same height.

Note: To lower the mower, move the cutting height levers forward; to raise the mower, move them towards the rear. (Figure 7)

1. Raise the Mower

2.Lower the Mower

Note: Height adjustment. 1"-3"

Starting the Engine

1.Press the primer three times

2. Hold the blade control bar (Figure 8) against the handle.

3. Hold blade control bar then pull the pull start to start the mower. (Figure 9)

Note: If the mower does not start after several attempts, please contact your authorized service center.

Stopping the Engine

To stop the engine, release the blade control bar (Figure 10)

Important: When you release the blade control bar, both the engine and the blade should stop within 3 seconds. If they do not stop properly, stop using your mower immediately and contact an authorized service center.

Mulching the Clippings

Your mower comes mulch ready. If you have a grass catcher please remove it before mulching.

Bagging the Clippings (Not Included) Use the grass catcher when you want to collect grass and leaf clippings from the lawn.

Operating Tips

General Mowing Tips

• Clear the area of sticks, stones, wire, branches, and other debris that the blade may hit.
• Avoid striking solid objects with the blade. Never deliberately mow over an object.
• If the mower strikes an object or starts to vibrate, immediately stop the engine, disconnect the spark plug and examine the mower for damage.
• Replace the blade when necessary with an AVVIX replacement blade.

Cutting Grass

• Cut only a third of the grass blade at a time. Do not cut bellow the 1.75 inch setting unless the grass is sparse or it is late in the fall when grass growth begins to slow down.
• When cutting grass over 6 inches tall, mow at the highest cutting height setting and walk slower. Then adjust your adjustment height lever to the desired height and mow again. If the grass is to tall it will be more difficult to navigate and could get stuck and cause the engine to stall.
• Alternate the mowing direction. This helps disperse the clippings over the lawn for even fertilization.
• If the finished lawn is unsatisfactory, try one or more of the following.

Replace the blade or have it sharpened.

Walk at a slower pace while mowing.

Raise the cutting height on your mower.

Cut the grass more frequently.

Overlap cutting swaths instead of cutting a full swath with each pass.

Set the cutting height on the front wheel one notch lower than the rear wheels. For example, set the front wheels at 2 inches and the rear at 2-1/2 inches

High Altitude Operation

Most small engines with carburetors are designed to work efficiently from sea level to around 5,000 feet elevation. As altitude increases, the air becomes thinner with less available oxygen. This causes the air/fuel mixture to become overly rich which can cause reduced performance, spark plug fouling, difficult starting and increased emissions.

A competent small engine shop can modify the carburetor by installing different 'jets' that are designed for high altitude operation. If your lawn mower is typically operated at an altitude of 5,000 feet or above, you should ask your dealer to 're-jet' the carburetor and calibrate the air fuel mixture to maximize performance at the altitude where it is to be used. You will realize better overall performance, while reducing excess emissions that occur when the air/fuel mixture is too rich. This modification need only be done once and should last for the life of the mower.

Keep in mind that any engine, even with properly calibrated carburetor jets, will realize a decrease in horsepower of about 3.5% for every 1,000 feet (300 meter) increase in altitude, simply due to thinner air. But an engine with a properly jetted carburetor will always run cleaner and more efficiently at high altitude than an identical unit with standard jets.

Spark Plug Maintenance

1. Once the engine has cooled, remove the spark plug wire.
2. Remove the spark plug using a spark plug wrench.
3. Clean the spark plug with a wire brush (not supplied).
4. Using a feeler gauge set the gap to 0.75mm.
5. Install the spark plug carefully by hand, to avoid cross-threading.
6. After the spark plug is seated, tighten with the spark plug wrench to compress the washer.
