GENERAL SAFETY PROCEDURES
For any questions regarding the hazard and safety notices listed in this manual or on the product, please call (800) 791-9458 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 1500F (650 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.

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 front and rear levers. Actuate the adjustment lever and pull it to the required position. Please make sure that the lever locks into same position.
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. 1. Add oil before starting mower for the first time. 2. 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 engines performance. Do not apply engine oil with additives or 2-stroke gasoline engine oil, because they haven't enough lubrication, and may shorten the engines 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 1. Remove the dipstick and Clean it. 2. Reinsert the dipstick into the oil filling hole, and insert it to the end. 3. Check the oil level: If the oil level is too low, add the recommended engine oil and make sure the oil level
between upper level(1) and lower level(2). 4. Re-install the dipstick.
13

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

Warning:

1. Gasoline is extremely flammable and is explosive under certain conditions.
2. 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.
3. 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.
4. 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.
5. 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: 1. Make sure the lawn mower is on a level surface. 2. Unscrew fuel tank 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
0.24gallons. 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 getting dirt or water into the fuel tank. Gasoline can age in the tank and make starting difficult. Never store lawn mower for extended periods of
time with fuel in the tank or the carburetor.

ENGINE START/STOP CONTROL This lawn mower comes equipped with an engine start/stop control to

Engine start/stop Control

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
14

several times after the engine has started up. When the engine start/stop Control 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 To start the engine, perform the following steps: 1. Check the oil and fuel levels. 2. Press the primer bulb 3 times. 3. 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.

Drive control bar

DRIVE CONTROL BAR If you press drive control bar the clutch for the drive will be closed and the lawn mower will start to move with the engine running, Release the drive control bar in good time to stop the moving lawn mower. 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 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 a number of 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. 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.
15

USING AS SIDE DISCHARGE You should close the rear cover with mulching adapter in order to use the side discharge. 1. On the side of the mower, lift the side discharge cover. 2. Slide two hooks of side discharge chute under hinge pin on the side discharge cover. Lower the side discharge
cover.
Caution: Do not remove side discharge cover at any time.
USING AS A REAR BAGGER To use the grass catcher to collect clippings while you are operating the mower. 1. Attached grass catcher following instruction in the lawn mower preparation. Grass clippings will
automatically collect in bag as you run the mower. Operate mower until grass catcher is full. 2. Stop engine completely by releasing the engine start/stop lever. Make sure that the engine has come to a
complete stop. 3. Lift rear discharge door and pull grass catcher up and away from the mower to remove the grass catcher.
Dispose of the grass clippings and reinstall the grass catcher when complete.
Warning: If you strike a foreign object, stop the engine. Remove spark plug wire, thoroughly inspect mower for any damage, and repair damage before restarting and operating. Excessive vibration of the mower during operation is an indication of damage. The mower should be promptly inspected and repaired.
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 valve from warranty, operator must maintain the lawn mower as instructed here. Changing of engine-governed speed will void 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 engine, allow engine to cool, disconnect spark plug wire before performing any type of maintenance on your machine.
DECK CARE
16

It is important to clean underside of the mower deck after use to prevent the build-up of grass clippings or other debris. Follow steps below for proper cleaning.
1. Allow the engine to run until it is out of fuel. Do not attempt to pour fuel from the engine. 2. Disconnect spark plug wire. 3. Slowly tip mower so that it rests on the housing. 4. To prevent oil spills, always tip the mower so that the Air Filter is facing up. 5. Hold mower firmly and scrape and clean the underside of the deck with a suitable tool. 6. 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: 1. Remove the dipstick and clean it. 2. Reinsert the dipstick into the Oil filling hole without screwing it and check Oil lever. 3. If the Oil lever is too low, add the recommended engine oil up to the oil upper lever. 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 16.9 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 (16.9 fl.oz) into the crankcase. 4. Reinstall dipstick.
17

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 gaped. Refer to Recommended Maintenance Schedule. To inspect the spark plug: 1. Remove spark plug boot. Be careful not to tear insulation or wire. 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.
