GENERAL SAFETY PROCEDURES
For any questions regarding the hazard and safety notices listed in this manual or on the product, please
call [phone] Mon-Fri 9-5 EST before using the engine.
DANGER: CARBON MONOXIDE
Using an engine indoors CAN KILL YOU IN MINUTES. Engine exhaust contains carbon
monoxide (CO). This is a poison gas you cannot see or smell. If you can smell the engine exhaust, you are
breathing CO. But even if you cannot smell the exhaust, you could be breathing CO.
NEVER use an engine inside homes, garages, crawlspaces, or other partly enclosed areas. Deadly levels
of carbon monoxide can build up in these areas. Using a fan, or opening windows and/or doors will NOT
properly vent CO nor supply adequate fresh air. ONLY use an engine outside and far away from windows,
doors, and vents. These openings can pull in engine exhaust.
Even if you use an engine correctly, CO may leak into the home. ALWAYS use a battery-powered or
battery-backup CO alarm in the home. If you start to feel sick, dizzy, or weak after the engine has been
running, move to fresh air RIGHT AWAY. See a doctor. You may have carbon monoxide poisoning.
WARNING: The exhaust from this product contains chemicals known to the State of California to cause
cancer, birth defects, or other reproductive harm.
WARNING: This engine may emit highly flammable and explosive gasoline vapors, which can cause
severe burns or even death if ignited. A nearby open flame can lead to explosion even if it isn’t directly in
contact with gasoline.
• Do not operate near an open flame.
• Do not smoke near the engine.
• Always operate on a firm, level surface.
• Always turn engine off before refueling. Allow engine to cool for at least 2 minutes before
removing fuel cap. Loosen cap slowly to relieve pressure in tank.
• Do not overfill fuel tank. Gasoline may expand during operation. Do not fill to the top of the tank.
Allow for expansion.
• Always check for spilled fuel before operating.
• Empty fuel tank and carburetor bowl before storing or transporting the engine.
WARNING: This engine produces heat when running. Temperatures near exhaust can exceed 150
0
F
(65
0
C).
Do not touch hot surfaces. Pay attention to warning labels on the engine identifying hot parts of the
machine.
Allow engine to cool down after use before touching engine or areas of the engine that become hot during
use.
CAUTION: Misuse of this engine can damage it or shorten its life.
Only use engine for its intended purposes.

5. Slowly add more oil and repeat step 4 until the oil mark reached to the upper mark of the dipstick. Do
not overfill the crankcase.
6. Check for oil leaks. Tighten dipstick firmly.
ADD GASOLINE
WARNING: This engine may emit highly flammable and explosive gasoline vapors, which
can cause severe burns or even death if ignited. A nearby open flame can lead to explosion
even if not directly in contact with gasoline.
Use fresh (within 30 days from purchase), lead-free gasoline with a minimum of 87 octane rating. Do not
mix oil with gasoline.
To add gasoline, follow these steps:
1. Make sure the engine is on a travel surface.
2. Unscrew fuel cap and set aside. NOTE: The fuel cap may be tight and hard to unscrew.
3. Slowly add unleaded gasoline to the fuel tank be careful not to overfill. The capacity of the fuel tank
is 0.9Gallon.NOTE: Do not fill the fuel tank to the very top. Gasoline will expand and spill over
during use even with the fuel cap in place.
4. Reinstall fuel cap and wipe clean any spilled gasoline with a dry cloth.
IMPORTANT:
 Never use an oil/gasoline mixture.
 Never use old gasoline.
 Avoid get dirt or water into the fuel tank

time with fuel in the tank or the carburetor.
ENGINE START/STOP LEVER
This lawn mower comes equipped with an engine start/stop lever to prevent
unintentional starting and to ensure safe operation. Releasing this lever will
quickly stop the blade in case of danger. The lever must be actuated before the
Engine start/stop lever

14
lawn mower is started. When the engine start/stop lever is released, it must return to its initial position.
Before you start mowing, you should run through this process several times in order to ensure that the
lever and actuator cables are working properly. Repeat the test several times after the engine has started
up. When the engine start/stop lever is released, the engine must stop within a few seconds. If not, contact
Customer Service.
Warning: The blade begins to rotate as soon as the engine is started.
START THE ENGINE
1. Ensure that the ignition cable is connected to the spark plug.
2. Stand behind the lawn mower. Actuate the engine start/stop lever with one hand. The other hand must
be on the starter handle.
3. Start the engine using the starter handle. To do this pull out the handle approx. 4 –6 inches (until you
feel a resistance) and then start the engine with a sharp tug. If the engine does not start, tug the handle
again.
Caution: Never allow the actuator cable to snap back.
Caution: In cold weather, it may be necessary to repeat the starting process several times.
STOP THE ENGINE
Release the engine start/stop lever to stop the engine.
DRIVE CONTROL BAR
If you press drive control bar the clutch for the drive will be closed and the
lawnmower will start to move with the engine running. Release the drive
control bar in good time to stop the moving lawnmower.
Practice starting and stopping before you use the mower for the first time until
you are familiar with controlling the mower.
MOWING
The engine throttle on your mower has been preset to provide optimum bagging and mulching
performance for years to come.
Only use a sharp blade that is in good condition. This will prevent the grass blades from becoming frayed
and the lawn from turning yellow.
Mow in straight lines for a nice, clean look. The swaths should overlap each other by a few inches in
order to avoid stripes.
It’s import to keep the underside of the mower deck clean and remove grass build-up. This buildup will
decrease mulching quality, and make it harder for the equipment to bag the grass.
Always mow along inclines (not up and down). You can prevent the lawn mower from slipping down by
holding a position at an angle upwards. Select the cutting height according to the length of the grass. If
necessary, mow a number of times so that you never cut more than 2 inches of grass in one go.

15
Turn off the engine before doing any checks on the blade. Keep in mind that the blade continues to rotate
for a few seconds after the engine has been turned off. Never attempt to manually stop the blade.
Regularly check to see if the blade is securely attached, is in good condition and is sharp. If the contrary
is the case, sharpen the blade or replace it. In the event that the blade strikes an object, immediately turn
off the lawn mower and wait for the blade to come to a complete stop. Then inspect the condition of the
blade and the blade mount. Replace any parts that are damaged.
USING AS MULCHING CONTROL LEVER
If the Grass Catcher is on the mower, and the Mulching Control Lever is
in the bagging position, move the lever to the mulching position before

17
CHECKING THE OIL
The oil capacity of the engine crankcase is 18 fl. oz.
Check the oil level of the engine according to the Recommended Maintenance Schedule.
The lawn mower should be checked before each use for proper oil level. This is a critical step for proper
engine starting.
To check the oil level:
1. Make sure the lawn mower is on a level surface.
2. Clean around oil fill. Remove dipstick and wipe the dipstick with a clean rag. Insert the dipstick into
the oil fill opening without screwing in. Remove the dipstick to check the oil mark. Add oil if the oil
mark covers less than one half of the dipstick.
3. Slowly add more oil and repeat step 2 until the oil mark reaches to the top of dipstick. Do not over fill
the crankcase.
4. Reinstall oil dipstick.
CHANGING/ADDING OIL
Change the oil according to the Recommended Maintenance Schedule. Change the oil when the engine is
warm. This will allow for complete drainage. Change oil more often if operating under heavy load or high
ambient temperatures. It is also necessary to drain the oil from the crankcase if it has become
contaminated with water or dirt. The oil capacity of the engine is 18 fl.oz. Add oil when the oil level is
low. For proper type and weight of oil refer to “GAS AND OIL FILL-UP” portion of the “OPERATION”
section.
To refill the crankcase with oil, follow these steps:
1. Make sure the lawn mower is on a level surface. Tilting the lawn mower to assist in filling will cause
oil to flow into engine areas and will cause damage. Keep lawn mower level!
2. Remove the dipstick from the engine.
3. Using a funnel or appropriate dispenser, add the correct amount of oil (18 fl.oz) into the crankcase.
4. Reinstall dipstick.
NOTE: Never dispose of used motor oil in the trash or down a drain. Please call a local recycling center
or auto garage to arrange oil disposal.
AIR CLEANER MAINTENANCE
Routine maintenance of the air cleaner helps maintain proper airflow to the carburetor. Occasionally
check that the air cleaner is free of excessive dirt. Refer to Recommended Maintenance Schedule. For air
cleaner detail:
1. Open the air cleaner cover.
2. Remove the sponge-like element from the casing.
3. Wipe the dirt from inside the empty air cleaner casing.
4. Wash the sponge-like element in household detergent and warm water. Small amount of oil in the
element is normal and necessary for the engine to work properly.
5. If necessary, replace the paper element.
6. Reinstall the sponge-like element in the air cleaner casing and reinstall the cover.
CAUTION: running the engine with dirty, damaged or missing air cleaner element will cause the engine
to wear out prematurely.
SPARK PLUG MAINTENANCE
The spark plug is important for proper engine operation. A good spark plug should be intact, free of
deposits, and properly gapped. Refer to Recommended Maintenance Schedule. To inspect the spark plug:
1. Remove spark plug boot. Be careful not to tear insulation or wire.

18
2. Unscrew the spark plug from the engine using the spark plug wrench provided. There is limited space
for the wrench to turn. Use both rows of holes in the spark plug wrench to gain leverage to loosen the
plug.
3. Visually inspect the spark plug for cracks or excessive electrode wear. Replace as necessary.
4. Measure the plug gap with a wire gauge. The gap should be 0.7 to 0.8 mm (0.028-0.031 in).
5. If re-using the spark plug, use a wire brush to clean any dirt from around the spark plug base then
re-gap the spark plug.
6. Screw the spark plug back into the spark plug hole using the spark plug wrench. Do not over-tighten
spark plug. Recommended tightening of spark plug is ½ to ¾ of a turn after spark plug gasket contacts
spark plug hole. Reinstall the spark plug boot.
