A new spark plug and clean air filter assure proper air-fuel mixture and help your engine run better and last longer. BEFORE EACH USE 1. Check engine oil level. 2. Check brake operation. 3. Check tire pressure. 4. Check operator presence and ROS systems for proper operation. 5. Check for loose fasteners. _General Purpose Grease @Refer to Maintenance "ENGINE" Section iMPORTANT: Do not oil or grease the pivot points which have special nylon bearings.
