Safety Checking and Filling Fuel Engine Oil Change WARNING! TO PREVENT SERIOUS INJURY FROM FIRE: Fill the fuel tank in a well-ventilated area away from ignition sources. If the engine is hot from use, shut the engine off and wait for it to cool before adding fuel. Do not smoke. CAUTION! Oil is very hot during operation and can cause burns. Wait for engine to cool before changing oil. 1. Clean the Fuel Cap and the area around it. 2. Unscrew and remove the Fuel Cap. 3.
Spark plug 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.
