MAINTENANCE LAWN MOWER BLADE Always observe safety rules when performing any maintenance. BLADE ADAPTER TRAILING EDGE TIRES • • Keep tires free of gasoline, oil, or insect control chemicals which can harm rubber. Avoid stumps, stones, deep ruts, sharp objects and other hazards that may cause tire damage. HARDENED WASHER DRIVE WHEELS Check rear drive wheels each time before you mow to be sure they move freely. The wheels not turning freely means trash, grass cuttings, etc.
MAINTENANCE NOTE: Multi-viscosity oils (5W30, 10W30 etc.) improve starting in cold weather, and you should check your engine oil level frequently to avoid possible engine damage from running low on oil. Change the oil after every 25 hours of operation or at least once a year if the lawn mower is not used for 25 hours in one year. Check the crankcase oil level before starting the engine and after each five (5) hours of continuous use. Tighten oil plug securely each time you check the oil level. 7.
