A worn grass catcher could allow small stones and
other similar debris to be thrown in the operator's or
bystanders direction and result in serious personal
injury or death to the operator or bystanders.
The blade is sharp. Contact with the blade can cause
serious personal injury.
Stop the engine and wait for all moving parts to stop
before leaving the operating position.
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 cable and examine the mower for damage.
• Replace the blade when necessary with a genuine
Pulsar replacement blade.
Cutting Grass
• When cutting grass over 6 inches tall, mow at the
highest cut setting and proceed slowly. After the first
pass, set your cutting height as desired and mow the
area again.
Wet grass or leaves can cause serious injury if you
slip and contact the blade. Mow only in dry conditions.
WARNING
WARNING
WARNING
• 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.
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.
