See DRIVE BELT REPLACEMENT (self-propelled models) on page 20. CHECK FASTENERS Check all fasteners for proper tightness. Pay special attention to blade hardware and all guards, shields and safety devices. CHECK AIR CLEANER See engine manual for specific information. CHANGE ENGINE OIL IMPORTANT: Change engine crankcase oil after first five (5) hours of operation. Then change oil after every 25 hours of operation. Refer to engine manual for instructions and proper oil type. IMPORTANT: Proper oil level must be maintained at all times or engine damage will result. DO NOT overfill. Be sure engine is level when adding oil. GENERAL LUBRICATION NOTE: The mower transmission is lubricated and sealed at the factory. It should need no routine lubrication. If the transmission leaks grease, bring the mower to your local Ariens dealer for repair. GB - 18 CHECK SPARK PLUG Spark plug should be replaced every 100 hours of operation or each year. NOTE: Loose spark plug wire terminals can cause sparking. Replace terminal if damaged. CHECK ENGINE COOLING WARNING: HOT SURFACES can cause death or serious injury. DO NOT TOUCH parts which are hot from operation. ALWAYS allow parts to cool. CHECK MUFFLER Check muffler for debris, cracks, wear, or other damage. CAUTION: Replace worn-out mufflers immediately. Continued use could result in fire or explosion. To prevent overheating, air must circulate freely around the cooling fins, cylinder head and block. Every 100 hours of operation or yearly (more often if conditions require) remove blower housing and clean cooling fins. See engine manual for instructions. SERVICE AND ADJUSTMENTS CAUTION: AVOID INJURY. Read and understand the entire Safety section before proceeding. SERVICE POSITION Put unit into service position for easy access to underneath the deck.
