Check mower blade balance before reinstalling blades. NEVER weld or straighten bent blades. 1. Remove mower blade from unit. Discard mower blade if: • More than 1/2 in. (1.27 cm) of metal is removed. • Air lifts become eroded. • Blade is bent or broken. 2. Sharpen mower blade by removing an equal amount of material from each end of mower blade. DO NOT change angle of cutting edge or round the corner of the mower blade. DO NOT Sharpen to This Pattern 12 DISCARD If More Than 1/2 in. (1.27 cm) 2 4 3 OT0792 Sharpen to This Pattern 1.

If either end of mower blade moves downward, sharpen the heavy end until blade is balanced (Figure 15). 4. Install mower blade on unit. 5. Tighten the bolts to a torque of 37.5 - 50 lbf-ft (51-68 N•m). Figure 15 OA0013 Bolt Blade CHECK DRIVE BELT (selfpropelled models) Check drive belt and replace if worn or damaged. 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. CAUTION: Avoid fuel spills. Follow steps below to help prevent fuel spills. If fuel leaks into air cleaner, replace air cleaner. ALWAYS clean up any spilled fuel. 1. Place unit on a flat, level surface. 2. Disconnect spark plug wire from spark plug. 3. Remove fuel cap, place a piece of plastic bag over the opening and tighten cap securely. 4. Tip unit onto right side (911112, 113). Tip unit onto left side, opposite the discharge opening (911110, 111). Make sure unit is secure and will not tip over. IMPORTANT: Remove plastic from fuel cap after unit is upright and service is complete. HANDLEBAR HEIGHT To adjust (Figure 16): 1. Remove hardware from lower handlebar mounting hole. 2. Rotate the handlebar up or down to the desired height and align the mounting holes with the holes in the handlebar upright. 3. Secure the handlebars in position with hardware removed in step 1. NOTE: To fold handlebars flat for storage, remove the hardware from the lower handlebar mounting holes, rotate the handlebars forward, and then replace the hardware in the holes on the handlebar upright.
