SECTION 1 - INTRODUCTION 1.1 THE MANUAL 1.5 DISCLAIMER Before operation of unit, carefully and completely read your manuals. The contents will provide you with an understanding of safety instructions and controls during normal operation and maintenance. Ariens reserves the right to discontinue, make changes to, and add improvements upon its products at any time without public notice or obligation. The descriptions and specifications contained in this manual were in effect at printing.
SECTION 2 - SAFETY 2.6 PREPARATION 2.1 SAFETY ALERTS Look for these symbols to point out important safety precautions. They mean: Before starting any removal of parts, proper preparation is very important for efficient work. A clean work area at the start of each job will allow you to perform service repairs easily and quickly.
DO NOT pull mower backwards unless absolutely necessary. Look down and back before and while moving backwards. When taking unit out of extended storage: 1. Check for any damage or loose parts. Repair, replace, or tighten hardware before operation. DO NOT start the engine or operate mower unless either the Side Discharge Opening Cover or the Side Discharge Deflector is installed. 2. If a preservative fluid was used in fuel tank, drain and discard. Fill fuel tank with fresh new fuel. 2.
Fuel is highly flammable and its vapors can explode. Use ONLY approved fuel containers. NO Smoking! NO Sparks! NO Flames! Allow engine to cool before servicing. NEVER fill fuel tank when engine is running, hot, or unit is indoors. Abnormal Vibrations are a warning of trouble. Striking a foreign object can damage unit. Stop unit and engine. Wait for all moving parts to stop. Remove wire from spark plug. Inspect unit and make any necessary repairs before restart. Hazardous Slopes Wear sturdy footwear.
Battery Spark Arrestor Avoid Electric Shock. DO NOT remove wire from spark plug while engine is running. Do not put battery in fire or mutilate. This product is equipped with an internal combustion engine. DO NOT use on or near any unimproved, forest or brush covered land unless the exhaust system is equipped with a spark arrestor meeting applicable local, state or federal laws. A spark arrestor, if used, must be maintained in effective working order by the operator.

Regularly check mower blades for wear and that lock washer is fully compressed by cap screw (requires 25-30 ft-lbs (33-40 Nm) of torque on cap screw). When blade needs sharpening: 1. Block blade to prevent rotation. 2. Remove cap screw, lock washer and blade from shaft. OM0240 Figure 5 4.
To check (Figure 7): 1. Start engine and slowly release control until engine stops firing. 5 2. Measure distance between handlebar and control at the point that engine stopped firing. 3 4 3. Turn cable nuts at handlebar mount clockwise if measurement is more than 1-1/4" or counterclockwise if measurement is less than 3/4". 1 2 4. Turn nuts against mount to lock in position.

To check the control cable spring: 1. Squeeze the wheel drive control bail towards the handlebar until the spring starts to open. 1 2 7 3 2. Measure the distance between the wheel drive bail to the handlebar indentation. 3. To obtain the proper adjustments turn the control cable nuts at the handlebar or the bottom of the control cable anchor against the anchor supports. 4 6 1 8 2 4 3 4 5 1. 2. 3. 4. 5. 3 Hole No. 1 Hole No. 2 Hole No. 3 Hole No. 4 Handlebar Stud 1 1.

5.3 ENGINE OIL IMPORTANT: Change engine crankcase oil after first two (2) hours of operation. Thereafter, change oil every twenty five hours of operation (more often in dusty dirty conditions). Refer to Engine Manual for oil type and grade and detailed instructions. Engine Oil Check and Change The engine crankcase oil should be checked daily or every five (5) hours of operation. Oil level MUST be maintained in safe operating range on dipstick at all times or engine damage will result.

5.5 ENGINE COOLING The engine is air cooled. Air must circulate freely around engine and over cooling fins on cylinder head and block to prevent overheating. Once a year or every one hundred (100) operating hours (more if conditions require) clean engine fins and external surfaces of engine of dust, dirt, and oil deposits which can contribute to improper cooling. Keep Areas within Heavy Line Clean of all Debris (Figure 16).
