General Mowing Tips
Cutting Grass
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
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.

3. Tip the mower onto its side, with the dipstick down, to drain the used oil out through the oil fill tube.(Figure 16) (Figure 12)

4. Slowly pour oil into the oil deposit until the oil level reaches the full line on the dipstick. (Figure 15) Do not overfill. (Max 13.5oz. (0.4 L), type: SAE 30 detergent oil with an API service of SF, SG, SH, SJ, SL, or higher.). Note: If you overfill the engine, pour some oil out of it as directed in Changing the Oil.

7. Install new blade with all mounting hardware; tighten blade bolt by turning clockwise. (Figure 16).

Service Interval: Before each use or daily
1. With the engine running on a flat paved surface,spray a stream of water in front of the right rear wheel(Figure 17). The water will splash into the path of the blade,cleaning out the clippings.

6. Install the spark plug and tighten it with a wrench 8. Use a torque Wrench to tighten the blade bolt to to 15 ft-lb (20 N-m). 30-38 ft-lb (40-50 N-m).
7. Tighten all nuts, bolts, and screws.
8. Leave spark plug cable disconnected. important. Use proper tools only!
1. Loosen the handle knobs until you can move the handle freely.
