SECTION 5 - ENGINE 5.1 ENGINE TROUBLESHOOTING The following troubleshooting chart is to be used to isolate engine problems and give possible causes and corrective action responses. TROUBLE Black Exhaust Blue/White Exhaust Difficult Starting Erratic Running Excessive Fuel Consumption High Oil Pressure Knocking Loss of Power or System Low Cranking Power Low Oil Pressure Misfiring Overheating Poor Compression Starts and Stops The troubleshooting key is generic and can be used for several types of engines.
NOTE: Run engine just prior to changing oil. Oil will flow more freely and carry away more contamination when warm. WARNING: Stop engine, remove key and wait for moving parts to stop before attempting any service procedures. 1. Drain engine crankcase by removing oil drain plug. After oil has drained, replace plug. 2. Remove oil fill cap and dipstick. CAUTION: DO NOT touch engine or riding mower parts which are hot from operation. Allow such parts to cool before servicing unit. 3.
5.5 SPARK PLUG 5.8 ENGINE REPLACEMENT Spark plug should be cleaned or replaced (if necessary) and gap reset to .030" every 100 hours of operation or yearly whichever comes first. 1. Remove debris from area around spark plug base. Consult parts manual to determine hardware used on replacement engine. NOTE: Depending on horsepower and manufacturer, various bolt patterns and amounts of hardware (taptites or cap screws) may be used to secure engine. 2. Remove spark plug from engine.

3. Sharpen both ends of blade at original angle (25o), removing equal amounts of material from each end to maintain proper blade balance. New blades are balanced to within 1.3 in. oz. at factory. DO NOT grind around corner at tip of blade. If cutting edge of blade cannot be sharpened in a straight line to within 1/8 of an inch of its end, replace blade with Ariens replacement blade only. 6 4. Install blade, lock washer, and tighten hardware to torque listed above.
should not be greater than 3/16". If it is greater than 3/16" see your Ariens dealer to have it corrected. 1 3 8.

SECTION 10 - BAGGER 10.2 BAGGER ASSEMBLY WARNING: When operating on slopes, front weight accessory (P/N 727016) is recommended. Tip over or complete loss of steering may result from any combination of excessive bagger load, operation on slopes, abrupt turns and speed changes. 1 2 10.1 VANE INSTALLATION 3 Since vanes generally require more power and generate more, try bagging without vanes first. If performance is satisfactory, use bagger without vanes.
10.3 LOWER BOOT INSTALLATION 28" and 32" Mower Pans 28" and 30" Mower Pans Position lower boot so that the two rear pan clips are in line with the notches in the boot. Place boot in front pan clip. Rotate boot counterclockwise until rear pan clips are seated properly in boot notches. Secure boot with L-pin. Lift deflector, slide bottom edge of lower boot between runner and bottom edge of mower pan.
SECTION 11 - ELECTRICAL 11.1 SAFETY INTERLOCK SYSTEM In the RUN position, there should be no continuity between contacts "B" and "S". DANGER: Failure of interlock, together with improper operation of unit, could result in severe personal injury. If after performing the above checks the engine does not start, check interlock module by disconnecting it at connector. This removes the module from electronic ignition circuit, If engine starts, module is defective and must be replaced.
After cleaning, apply a thin coat of grease or petroleum jelly to terminals and cable ends, to retard corrosion. Reinstall battery. CAUTION: Connect positive (+) cable first, negative (-) cable last. discharged, a battery charger will be required for recharging. Before using a charger, an attempt can be made to recharge the battery using the engine alternator by jump starting the unit and allowing the to engine run.
