• When cutting grass over 6 inches tall, mow at the highest cutting hei-
ght 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.
WARNING
Wet grass or leaves can cause serious injury if you slip and contact the
blade. Mow only in dry conditions.
• Alternate the mowing direction. This helps disperse the clippings over
the lawn for even fertilization.
• If the nished 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 emis-
sions that occur when the air/fuel mixture is too rich. This modication
need only be done once and should last for the life of the mower.
Keep in mind that any engine, even with properly calibrated carbure-
