SAFETY WARNING: AVOID INJURY. This snow thrower is capable of crushing or amputating body parts. Failure to observe the safety instructions in the manuals and on decals could result in serious injury or death. ALWAYS disengage auger, stop unit and engine, remove key and allow moving parts to stop before leaving operator’s position. Read these safety rules and follow them closely.
4. Notice Safety Decal Descriptions NOTICE: Indicates information or procedures that are considered important but not hazard related. If not followed, property damage could result. 1. CAUTION! Danger! 5. Important IMPORTANT: Indicates general reference information worthy of special attention. SAFETY DECALS The safety decals on your machine are visual reminders of the important safety information in this manual. All messages on your unit must be fully understood and carefully followed.
Complete a walk-around inspection of the unit to understand the unit, your work area and all safety decals. 2. DANGER! Understand how to operate all controls, the functions of all controls and how to STOP in an emergency. Danger! ROTATING PARTS! Keep clear of auger while engine is running. • Read operator’s manual. • Allow operation only by properly-trained adult, never children. • Stop engine and remove ignition key prior to leaving the operator’s position for any reason.
Never attempt to make any adjustments while the engine is running (except when specifically recommended by manufacturer). Always allow unit and engine to adjust to outdoor temperature before clearing snow. Never operate the snow thrower without proper guards, and other safety protective devices in place and working. Operation Disengage all controls before starting engine. Always stand clear of the discharge area when operating this unit. Never leave a running unit unattended.
Avoid contact with sharp edges; sharp edges can cut. Always refer to operator's manual for important details if the snow thrower is to be stored for an extended period. Do not throw snow higher than necessary. Clearing a Clogged Discharge Chute Maintain or replace safety and instruction labels as necessary. Hand contact with the rotating auger / impeller inside the discharge chute is the most common cause of injury associated with snow throwers. Never use your hand to clean out the discharge chute.
Fuel is highly flammable and its vapors are explosive. Handle with care. Use only an approved gasoline container with an appropriately-sized dispensing spout. No smoking, no sparks, no flames. Always allow engine to cool before servicing. Never fill fuel tank when engine is running or hot from operation. Never fill or drain fuel tank indoors. Replace fuel cap securely and clean up spilled fuel. Never fill fuel containers inside a vehicle or on a truck or trailer bed with a plastic liner.

TRACTION DRIVE CLUTCH LEVER (LEFT SIDE) DISCHARGE CHUTE DEFLECTOR LEVER See Figure 6. Allows unit to travel forward and in reverse. See Figure 8. Moves discharge deflector up or down to control height of snow discharge. Figure 6 DUAL HANDLE INTERLOCK Allows auger / impeller to rotate without holding attachment clutch lever continuously. Auger continues to turn until both clutch levers are released. DISCHARGE CHUTE ROTATION LEVER See Figure 7.
HEIGHT ADJUSTMENT LEVER (RIGHT SIDE) IMPORTANT: Use fresh unleaded fuel with an octane rating of at least 87. DO NOT use E85 blended fuels; the engine is not E20 / E30 / E85 compatible. The maximum recommended ethanol content is 10%. Ariens recommends using a quality fuel stabilizer in all fuel. See Short Term on page 27. Model 920032 See Figure 9. Raises or lowers auger housing for various snow-clearing situations. 3. Check engine oil level and add oil if needed. Refer to engine manual. 4.
OPERATE UNIT Wheel Operation 1. Rotate discharge chute and move deflector to desired positions. 2. Select desired speed. 3. Engage attachment clutch. NOTICE: Stop auger when traveling between work areas. 4. Engage traction drive clutch. NOTICE: Release lever before changing speed. Adjust Track Angle Model 920032 See Figure 10. • Wheel Operation: Allows for maximum maneuverability and ease of turning for locations not requiring high traction. Squeeze height adjustment lever and push down on handlebar.
Set Axle Lock Pin Models 920025, 920030, 920033 NOTICE: Wheels must be locked in the outer axle holes when using tire chains. See Figure 11. Axle lock pins may be positioned so both wheels lock with axle rotation for greater traction, or so one wheel is unlocked from axle and rotates freely for easier turning. For greater traction: 1. Align both wheel hub holes with inner axle holes and insert lock pins. For easier right turns: 1. Remove lock pin from right wheel hub. 2.
