Spark plug Maintenance Spark Plug Cap Safety Setup Operation 1 GALLON UNLEADED GASOLINE 2.5 FLUID OUNCES 2-CYCLE OIL APPROVED CONTAINER Figure D: Fuel-Oil Mixture 4. To obtain the proper gasoline and 2-cycle oil mixture, mix 2.5 fluid ounces of 2-cycle oil with 1 gallon of 87 octane or higher unleaded gasoline that has been treated with a fuel stabilizer additive into an approved container. Then gently agitate the container to thoroughly mix the gasoline/2-cycle oil. 5. If needed, fill the Fuel Tank to about 1 inch under the fill neck of the Fuel Tank with the pre‑mixed stabilizer-treated unleaded gasoline/2-cycle oil mixture. 6. Then replace the Fuel Cap. 7. Wipe up any spilled fuel and allow excess to evaporate before starting engine. To prevent FIRE, do not start the engine while the smell of fuel hangs in the air. Air Filter Maintenance 1. Remove the Air Cleaner Cover and the air filter(s) and check for dirt. Clean as described below. 2. Cleaning: • For paper filters: To prevent injury from dust and debris, wear ANSI-approved safety goggles, NIOSH‑approved dust mask/respirator, and heavy-duty work gloves. In a well‑ventilated area away from bystanders, use pressurized air to blow dust out of the filter. • For foam filters: Wash the filter in warm water and mild detergent several times. Rinse. Squeeze out excess water and allow it to dry completely. Soak the filter in lightweight oil briefly, then squeeze out the excess oil. 1. Disconnect spark plug cap from end of plug. Clean out debris from around spark plug. 2. Using a spark plug wrench, remove the spark plug. 3. Inspect the spark plug: If the electrode is oily, clean it using a clean, dry rag. If the electrode has deposits on it, polish it using emery paper. If the white insulator is cracked or chipped, the spark plug needs to be replaced. Recommended Spark Plugs BONON® F5TC NOTICE: Using an incorrect spark plug may damage the engine. 4. When installing a new spark plug, adjust the plug's gap to the specification on the Specifications chart. Do not pry against the electrode, the spark plug can be damaged. 5. Install the new spark plug or the cleaned spark plug into the engine. • Gasket-style: Finger-tighten until the gasket contacts the cylinder head, then tighten about 1/2-2/3 turn more. • Non-gasket-style: Finger-tighten until the plug contacts the cylinder head, then tighten about 1/16 turn more. NOTICE: Tighten the spark plug properly. If loose, the spark plug will cause the engine to overheat. If overtightened, the threads in the engine block will be damaged. 6. Apply dielectric spark plug boot protector (not included) to the end of the spark plug and reattach the wire securely. Page 12 For technical questions, please call 1-888-866-5797.
