Filling the Fuel Tank
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
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. (Fig. 8)
Important: To reduce starting problems, add fuel
stabilizer to the fuel, mixing it with gasoline less than
30 days old. (Fig. 8)

WARNING

Cutting Height Adjustment
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 mower deck when
adjusting the cutting height.
Starting the Engine
2. Hold the blade control bar (Fig. 11) against
the handle.
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.

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.
TO ADJUST CUTTING HEIGHT (Fig. 10)
Raise wheels for low cut and lower wheels for high cut,
adjust cutting height to suit your requirements. Medium
position is best for most lawns.
Tochange cutting height, pull adjuster lever toward wheel.
Move wheel up or down to suit your requirements.
Be sure all wheels are in the same setting.
NOTE: Adjuster is properly positioned when plate tab inserts
into hole in lever. Also, 5-position adjusters (if so equipped)
allow lever to be positioned between the plate tabs.

Primer

A worn grass catcher could allow small stones and

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.
6
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
altitude operation. If your lawn mower is typically operated
at an altitude of 5,000 feet or above, you should ask your
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.
