Engine oil CAUTION: Running the engine with low oil level will cause serious engine damage. Wipe the dipstick up. Put the dipstick into the oil filler neck, and screw it in. If the level is low, fill the recommended oil to the middle of the oil dipstick. Use high‐detergent, premium quality 4‐stroke engine oil, certified to meet or exceed U.S. automobile manufacturer’s requirement for API Service Classification SG, SF. CAUTION: Using non‐detergent oil or 2‐stroke engine oil could shorten the engine’s service life. SAE 10w‐30 is recommended for general, all temperature use. Other viscosities shown in the following chart might be used when the average temperature in your area is within the indicated range. 5.2.

Refill with the recommended oil and check its level. Oil capacity: refer to chapter 12 specifications Wash your hands with soap and water after touching used oil. NOTE: Please dispose used motor oil in a manner that is compatible with the environment. We suggest you put it in a sealed container to your local service for reclamation. Do not throw it to the trash can or pour it on the ground. 9.2 Air Filter Service A dirty air cleaner will block air flow into the carburetor. To prevent carburetor malfunction, service the air cleaner regularly. Service more frequently when operating the engine in extremely dusty areas. WARNING Never use gasoline or low flash point solvents to clean the air cleaner element. A fire or explosion could result in. CAUTION: Never run the engine without air cleaner, or rapid engine wear will be the result. Remove the wing nut and the air cleaner cover. Remove the elements and separate them. Carefully check elements for holes and tears, and replace it if damaged. Foam element: clean in warm soapy water, risen and allow to dry thoroughly or clean in high flash‐point solvent and allow to dry. Dip the element in clean engine oil and squeeze out all the excess. The engine will smoke during initial start –up if too much oil is left in the foam. Paper element: Tap the element lightly several times on a hard surface to remove excess dirt or blow compressed air through the filter from the inside out. Never try to brush the dirt off, for so doing will force dirt into the fibers. 9.3 Fuel Strainer Cup Cleaning WARNING Gasoline is highly flammable and explosive under certain conditions. Do not smoke or allow flames of sparks in the area. Remove the fuel strainer cup and the O‐ring. Wash the removed parts in solvent, dry them thoroughly and reinstall them securely. 19 ...
Page 23 9.4 Spark plug service Recommended spark plug: BPR5ES (NGK) F7RTC (LG) To ensure proper engine operation, the spark plug must be properly gapped and free of deposits. Remove the spark plug cap. WARNING If the engine has been running the muffler will be very hot. Be careful not to touch the muffler. Visually inspect the spark plug. Discard it if the insulator is cracked or chipped. Measure the plug gap with a feeler gauge. The gap should be 0.7‐0.8mm (0.028‐0.031 in), Correct as necessary by bending the side electrode. Attach the plug washer, thread the plug in by hand to prevent cross‐threading. When mounting a new spark plug, you should screw 1/2 more thread with the wrench after the washer is compressed. If you are mounting an old one, you should only screw 1/8‐1/4 more thread. CAUTION: The spark plug must be securely tightened. An improperly tightened plug can become very hot and possibly damage the engine. Never use a spark plug with an improper heat range. 20 ...
Page 24: Transporting And Storage
Transporting and Storage WARNING When transporting the tiller, turn the fuel valve OFF and keep the tiller level to prevent fuel spillage. Fuel vapor or spilled fuel may be ignited. Before storing the unit for an extended period, follow below steps. Be sure the storage area is free of excessive humidity and dust. Drain the fuel. WARNING Gasoline is highly flammable and explosive under certain conditions. Do not smoke or allow flames or sparks in the area. With the fuel valve turned OFF, remove and empty the fuel strainer cup. Turn the fuel valve ON and drain the gasoline in the fuel tank into a suitable container. Replace the fuel strainer cup and tighten securely. Drain the carburetor by loosening the drain knob. Drain the gasoline into a suitable container. Pull the starter grip until resistance is felt. Continue pulling until the notch on the starter puller aligns with the hole on the recoil starter. At this point, the intake and exhaust valves are closed and this will help to protect the engine from internal corrosion. Change engine oil. Cover tiller with plastic sheet. Do not place the tiller with the handlebars on the ground. It will cause the oil entering the cylinder or the fuel spillage.
