FAILURE TO OBSERVE THE FOLLOWING SAFETY INSTRUCTIONS COULD RESULT IN SERIOUS INJURY OR DEATH. WARNING: In order to prevent accidental starting when setting up, transporting, adjusting or making repairs, always disconnect spark plug wire and place wire where it cannot contact spark plug. WARNING: Do not coast down a hill in neutral, you may lose control of the tractor. [. . . ] 12 • If grass is extremely tall, it should be mowed twice to reduce load and possible fire hazard from dried clippings. Make first cut relatively high; the second to the desired height. Wet grass will plug mower and leave undesirable clumps. Always operate engine at full throttle when mowing to assure better mowing performance and proper discharge of material. Regulate ground speed by selecting a low enough gear to give the mower cutting performance as well as the quality of cut desired. When operating attachments, select a ground speed that will suit the terrain and give best performance of the attachment being used. • • • 13 MAINTENANCE MAINTENANCE SCHEDULE Check Brake Operation BEFORE EACH USE EVERY 8 HOURS EVERY 25 HOURS EVERY 50 HOURS EVERY 100 HOURS EVERY SEASON BEFORE STORAGE T R A C T 0 R Check Tire Pressure Check Operator Presence & ROS Systems Check for Loose Fasteners Check/Replace Mower Blades Lubrication Chart Check Battery Level Clean Battery and Terminals Clean Debris Off Steering Plate Check Transaxle Cooling Check Mower Levelness Check V-Belts Check Engine Oil Level Change Engine Oil (with oil filter) 1, 2 1, 2 2 2 5 4 3 E N G I N E Change Engine Oil (without oil filter) Clean Air Filter Clean Air Screen Inspect Muffler/Spark Arrester Replace Oil Filter (If equipped) Clean Engine Cooling Fins Replace Spark Plug Replace Air Filter Paper Cartridge 1, 2 2 2 Replace Fuel Filter 1 - Change more often when operating under a heavy load or in high ambient temperatures. 2 - Service more often when operating in dirty or dusty conditions. 3 - Replace blades more often when mowing in sandy soil. 4 - Not required if equipped with maintenance-free battery. 5 - See Cleaning in Maintenance Section.
