safety protection, frequentl y check componen ts and
replace immediatel y with original equipm ent
manufacturer’s (O.E.M .) parts only , listed in this ma nual.
“Use of parts which do not m eet the ori ginal eq uipment
specifications ma y lead t o imprope r performan ce and
compromise safety!”
10. Do not change t he engine governor setting o r overs peed

SECTION 5: OPERATING YOUR LAWN MOWER
Towards Better Mower Performance
1. Pour fresh, clean gasoline into the mower’s gas
tank until the tank is full. Do not use gasoline
that is more than 30 days old.
2. Always use a fuel stabilizer. It will double the life
of the gasoline used.
3. Make sure to connect the mower’s spark plug
wire before trying to start the engine.
4. Add engine oil to the oil fill on the mower engine.
Check the dipstick and add more if necessary.
Remember that the oil level has to touch the fill
line.
5. Locate the primer decal near the primer bulb on
the engine, and read its instruction. Using your
thumb, press the primer bulb slowly as many
times as the deca l advises.
WARNING: Keep hands and feet away from
chute area on the cutting deck. The
operation of any lawn mower can result in
foreign objects being thrown into the eyes,
which can result in severe eye damage.
Always wear safety glasses or eye shields.
6. Hold control handle down and pull rope firmly to
start the engine.
7. Set cutting height adjustment lever to middle
setting and mow a single pass on your lawn;
then adjust to desired height for a closer cut.
8. To mulch insert the mulch plug/cover on the
mower.
9. In heavy growing season, it may be necessary
to mow lawn twice weekly. Clumps of grass
clippings left behind on the lawn usually means
that the grass is too high to mulch.
10. Before storing the lawn mower for the winter,
use stabilizer-treated fuel and run the tank dry.
11. Thirty days before start of the new season,
check the air filter, spark plug and blade on the
lawn mower, and replace if needed.
NOTE: For shipping pur poses your mower is set with
the wheels in a low cutting height position. For best
results raise the cutting position until it is determine
which height is best for your lawn. See the Adjustment
Section for details.

Gas and Oil Fill-Up
Service the engine with gasoline and oil as instructed in
the separate engine manual packed with your mower.
Read instructions carefully.
WARNING: Never fill fuel tank indoors with
engine running or until the engine has
been allowed to cool for at least two
minutes after running.
Starting Engine
• Attach spark plug wire to spark plug. Make certain
the metal cap on the end of the spark plug is
fastened securely over the metal tip on the spark
plug.
• Prime engine as instructed in the separate engine
manual packed with your unit.
• Your lawn mower may be equipped with a constant
speed throttle, which is set at full throttle for best
performance.
• Stand behind the mower and squeeze the blade
control handle against the upper handle.
• Grasp recoil starter handle and pull rope out slowly
until engine reaches the start of compression cycle
(rope will pull slightly harder at this point). Let the
rope rewind slowly. Pull rope with a rapid,
continuous, full arm stroke. Keeping a firm grip on
the starter handle, let the rope return to the starter
slowly.
Using Y our Lawn Mow er
Be sure the lawn is clear of stones, sticks, wire, or other
objects which could damage the lawn mower or the
engine. Such objects could be accidently thrown by the
mower in any direction and cause serious personal
injury to the operator and others.
For best results, do not cut wet grass because it tends
to stick to the underside of the mower, preventing
proper discharge of grass clippings, and could cause
you to slip and fall. New grass, thick grass, or wet grass
may require a narrower cut.
For a healthier lawn, never cut off more than one-third
of the total length of the grass. Your lawn should be cut
in the fall as long as there is growth. This mower is
designed to be operated at full throttle to give you the
best cut and do the most effective job of mowing or
mulching.
WARNING: If you strike a foreign object,
stop the engine. Remove wire from the
spark plug, thoroughly inspect the mower
for any damage, and repair the damage
before restarting and operating the
mower. Extensive vibration of the mower
during operation is an indication of
damage. The unit should be promptly
inspected and repaired.
Mulching
For effective mulching, do not cut wet grass because it
tends to stick to the underside of the deck, preventing
proper mulching of grass clippings. New or thick grass
may require a narrower cut. The ground speed should
be adjusted to the condition of the lawn. If mowing has
been delayed and the grass has been allowed to grow
in excess of 4”, mulching is not recommended. Mow
using the side discharge to reduce the grass height to 3
1/4” maximum before mulching.
SECTION 6: MAKING ADJUSTMENTS
Cutting Height Adjustment
WARNING: Always stop engine, disconnect spark plug, and ground against
engine before performing adjustments.
Each wheel has a height adjustment lever which
provides cutting height adjustment. When the
adjustment lever is moved from one location to another
the height of cut will be changed. Simply depress the
lever towards wheel and move lever assembly to
desired position. See .
IMPORT ANT :

height adjustment lever to a higher position. This will
help stop scalping of the grass.
All wheels must be placed in the same

WARNING: Always stop engine, disconnect spark plug, and ground against
engine before cleaning, lubricating or
doing any kind of maintenance on your
machine.
Blade Control Handle: Lubricate the pivot points on
the blade control handle at least once a season with
light oil. The blade control must operate freely in both
directions. See Figure 11.
Wheels: Lubricate the wheels at least once a season
with light oil (or motor oil). If the wheels are removed for
any reason, lubricate the surface of the axle bolt and
inner sur face of the whee l wit h lig ht oi l.

• The spark plug should be cleaned and the gap
reset once a season. Spark plug replacement is
recommended at the start of each mowing season.
Clean the engine regularly with a cloth or brush. Keep
the cooling system (blower housing area) clean to
permit proper air circulation which is essential to engine
performance and life. Be certain to remove all grass,
dirt, and combustible debris from muffler area.
Deck
The underside of the mower deck should be cleaned
after eac h use to pr even t a bu ildup of gr ass c lippi ngs,
leaves, dirt, or other matter. If this debris is allowed to
accumulate, it will invite rust and corrosion, and may
prevent proper mulching, discharge, or bagging. The
deck may be cleaned by tilting the mower and scraping
clean with a suitable tool (make certain the spark plug
wire is disconnected).
IMPORT ANT :
pressure washer or garden hose to clean your unit.

keep the air cl eaner side of engine up. Never t ip the
mower more than 90 degrees and do not leave the
mower tipped for any length of time. O il can drain into
the upper part of the engine causing a starting problem.
Engine
Refer to the separate engine manual for all engine
maintenance instructions.
• Maintain engine oil as instructed in the separate

WARNING: Periodical ly inspect the blade
adapter for cracks , espec ially if yo u st rike
a foreign object. Replace when necessary.
When sharpening the blade, follow the original angle of
grind as a guide. It is extremely important that each
cutting edge receives an equal amount of grinding to
prevent an unbalanced blade. An unbalanced blade will
cause excessive vibration when rotating at high
speeds. It may cause damage to the mower, and could
break causing personal injury.
12
The blade can be tested by balancing it on a round
shaft screwdriver. Remove metal from the heavy side
until it balances evenly. It is recommended that the
blade always be removed from the adapter when
testing for balance. Before reinstalling the blade and
the blade adapter to the unit, lubricate the engine
crankshaft and the inner surface of the blade adapter
with light oil.
• Be sure to install the blade with the end tips facing
up or side of the blade marked “Bottom” (or with
part number) facing the ground when the mower is
in the operating position.
