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 an 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 the engine off before refueling. Allow the engine to cool for at least 2 minutes before removing the fuel cap. Loosen the cap slowly to relieve pressure in the tank.
Do not overfill the 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 the fuel tank and carburetor bowl before storing or transporting the engine.
WARNING: This engine produces heat when running. Temperatures near exhaust can exceed 1500F (650 C).
Do not touch hot surfaces. Pay attention to warning labels on the engine identifying hot parts of the machine.
Allow the engine to cool down after use before touching the 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 the engine for its intended purposes.

OPERATION

GAS AND OIL FILL-UP

The engine comes shipped without oil or gasoline. Be sure to add oil and gasoline before starting the engine. The oil capacity of the engine crankcase is 16.9 fl. oz. For general use, we recommend 10W-30, 4-stroke engine oil.

Add oil before starting the mower for the first time.
Service the engine with gasoline as instructed.

Warning: Use extreme care when handling gasoline. Gasoline is extremely flammable and its vapors are explosive.
Never fuel the machine indoors or while the engine is hot or running. Extinguish all cigarettes, cigars, pipes, and other potential sources of ignition.

Engine Oil

Engine oil is a key factor in deciding the performance of the engine. Do not apply engine oil with additives or 2-stroke gasoline engine oil, because they haven’t enough lubrication, and may shorten the engine’s service life.
Check the engine with it stopped on a level ground.
Engine oil recommended : 10W-30
As viscosity varies with regions and temperatures, SF-class oil is recommended.

Check method

Remove the dipstick and Clean it.
Reinsert the dipstick into the oil-filling hole, and insert it into the end.
Check the oil level: If the oil level is too low, add the recommended engine oil and make sure the oil level is between the upper level (1) and the lower level (2).
Re-install the dipstick.

Adding Gasoline

Remove the fuel tank cap and check the fuel level.
If the level is too low, refuel the tank, remember adding fuel not over the fuel upper level.

Warning:

Gasoline is extremely flammable and is explosive under certain conditions.
Refueling in a well-ventilation area with the engine stopped. Do not smoke and allow flames or sparks in the area where gasoline is stored or where the fuel tank is refueled.
Do not overfill the fuel tank (there should be no fuel in the filling neck). After refueling, make sure the fuel tank cap is set back securely.
Be careful not to spill fuel when refueling. Spilled fuel or fuel vapor may ignite. If any fuel is spilled, make sure the area is dry before starting the engine.
Avoid repeated or prolonged contact with skin or breathing of fuel vapor. Keep out of reach of children.
- 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:

Make sure the lawn mower is on a level surface.
Unscrew the fuel tank cap and set it aside.
NOTE: The fuel cap may be tight and hard to unscrew.
Slowly add unleaded gasoline to the fuel tank. Be careful not to overfill. The capacity of the fuel tank is 0.21 gallons.
- 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.
Reinstall the fuel cap and wipe clean any spilled gasoline with a dry cloth.

IMPORTANT:

Never use an oil/gasoline mixture.
Never use old gasoline.
Avoid getting dirt or water into the fuel tank.
Gasoline can age in the tank and make starting difficult. Never store lawnmowers for extended periods with fuel in the tank or the carburetor.

ENGINE START/STOP CONTROL

This lawn mower comes equipped with an engine start/stop control 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 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
Control is released, and 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 To start the engine, perform the following steps:

Check the oil and fuel levels.
For cold starting, slightly press the primer bulb one to three times. For hot starting, directly pull the recoil starter handle.
Engage the engine Start/Stop Control and simultaneously pull on the recoil starter. Pull on the recoil starter handle slowly until a slight resistance is felt, then pull quickly to start the engine.
- Return the cord gently to the recoil starter. Never allow the cord to snap back.
If an engine fails to start, repeat step 3.

NOTE: After repeated failed attempts to start the engine, please consult the troubleshooting guide before attempting again. If problems persist, please call customer service.
NOTE: Don’t allow the starter grip to snap back against the engine. Return it gently to prevent damage to the starter.

STOP THE ENGINE

Release the engine start/stop control to stop the engine.

ADJUSTING THE CUTTING HEIGHT

Warning! Cutting height adjustments should only be performed after the engine and blades have come to a complete stop!
It is always best to begin cutting your lawn with a higher deck height to prevent scalping your lawn.
The cutting height is adjusted with the lever.
Actuate the adjustment lever and pull it to the required position.

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 to avoid stripes.
It’s important 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 many times so that you never cut more than 2 inches of grass in one go.
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.
If 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.

MAINTENANCE

Proper routine maintenance of this mower will help prolong the life of the machine.
Always observe safety rules when performing any maintenance.
The warranty on this lawn mower does not cover items that have been subjected to operator abuse or negligence. To receive full value from the warranty, the operator must maintain the lawn mower as instructed here.
Changing of engine-governed speed will void the engine warranty.
All adjustments should be checked at least once each season.
Periodically check all fasteners and make sure these are tight.
Warning: Always stop the engine, allow the engine to cool, and disconnect the spark plug wire before performing any type of maintenance on your machine.

DECK CARE

It is important to clean the underside of the mower deck after use to prevent the build-up of grass clippings or other debris. Follow the steps below for proper cleaning.

Allow the engine to run until it is out of fuel. Do not attempt to pour fuel from the engine.
Disconnect the spark plug wire.
Slowly tip the mower so that it rests on the housing.
To prevent oil spills, always tip the mower so that the Air Filter is facing up.
Hold the mower firmly and scrape and clean the underside of the deck with a suitable tool.
Gently lower the mower back on its wheels on the ground.

Warning: Never tip the mower more than 90° in any direction and do not leave the mower tipped for any length of time. Oil can drain into the upper part of the engine causing a starting problem.

MOWER BLADE

To ensure safe operation, have all blade sharpening, balancing, and mounting work carried out by an authorized service center.
To achieve optimal results, we recommend having the blade checked once a year.
If, in spite of all caution, the blade comes into contact with an obstacle, switch off the engine immediately and pull off the spark plug connector.
Tilt the lawn mower to the rear and check the blade for damage. Always keep the side with the air cleaner facing up.
Damaged or bent blades must be replaced. Never straighten a bent blade. Never work with bent or heavily worn blades as this will result in vibrations, causing further damage to the mower.
Warning: Risk of injury when working with a damaged blade.

CHECKING THE OIL

The oil capacity of the engine crankcase is 16.9 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:

Remove the dipstick and clean it.
Reinsert the dipstick into the Oil filling hole without screwing it and check the Oil level.
If the Oil level is too low, add the recommended engine oil up to the oil upper level.
Reinstall the 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 16.9 fl. oz. Add oil when the oil level is low. For the proper type and weight of oil refer to the “GAS AND OIL FILL-UP” portion of the “OPERATION” section.

To refill the crankcase with oil, follow these steps:

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!
Remove the dipstick from the engine.
Using a funnel or appropriate dispenser, add the correct amount of oil (16.9 fl. oz) into the crankcase.
Reinstall the 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 the Recommended Maintenance Schedule. For air cleaner detail:

Open the air cleaner cover.
Remove the sponge-like element from the casing.
Wipe the dirt from inside the empty air cleaner casing.
Wash the sponge-like element in household detergent and warm water. The small amount of oil in the element is normal and necessary for the engine to work properly.
If necessary, replace the paper element.
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 elements 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 gaped. Refer to the Recommended Maintenance Schedule. To inspect the spark plug:

Remove the spark plug boot. Be careful not to tear insulation or wire.
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.
Visually inspect the spark plug for cracks or excessive electrode wear. Replace as necessary.
Measure the plug gap with a wire gauge. The gap should be 0.028-0.031 inch.
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.
Screw the spark plug back into the spark plug hole using the spark plug wrench. Do not over-tighten the spark plug. Recommended tightening of the spark plug is ½ to ¾ of a turn after the spark plug gasket contacts the spark plug hole. Reinstall the spark plug boot.
