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.

ATTACHMENT CLUTCH LEVER (RIGHT SIDE) WARNING: Read and understand the Safety section before proceeding. See Figure 5. Controls auger / impeller movement. See Figure 3 for all controls and features locations. ENGINE KEY Controls power to the engine. The key cannot be removed when in run position. PRIMER BULB Adds fuel to engine for easier start on cold engines. FUEL VALVE Controls fuel flow to the engine. ELECTRIC START BUTTON Starts a correctly choked engine.
DISCHARGE CHUTE ROTATION LEVER HEATED HAND GRIP SWITCH Turns the heated hand grips on and off. See Figure 7. Rotates discharge chute to control snow discharge. Pull lever back to unlock chute, move lever left or right to desired position, and then push lever forward to lock chute in place. SCRAPER BLADE Contacts the surface being cleared and protects the housing from damage during normal use. DRIFT CUTTER Breaks up snow drifts that are taller than the auger housing and directs snow into auger.
c. If handle does not pull, move unit to a warm area to thaw. 2. Check fuel level and add fuel if needed. 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 23. 3. Check engine oil level and add oil if needed. Refer to engine manual. 4. Check function of controls.
NOTICE: NEVER secure from rods or linkages that could be damaged. See Figure 10. 2. Rotate drift cutter forward 180 degrees until notch engages upper wing knob. Tighten wing knobs. 3. Repeat on other side. ENGINE OPERATION ANGLE Engine angle during operation can affect how well the engine is lubricated regardless of oil level. Operating beyond the engine manufacturer’s recommended maximum angle will lead to premature engine wear and void the engine warranty.
Service Performed Each Use Every 5 hrs. Every 25 hrs. Annually As Needed. MAINTENANCE SCHEDULE Add Fuel Stabilizer * Check Attachment Drive Clutch Operation • Check Traction Drive Clutch Operation • Check Engine Oil ** CHECK FASTENERS • Check Tire Pressure 1. Stop engine. 2. Engage attachment clutch and then the traction drive clutch. 3. Release the attachment clutch lever. The attachment clutch should stay engaged until the traction drive clutch lever is released.
CHANGE ENGINE OIL LUBRICATE UNIT Refer to engine manual. Ariens recommends using Ariens Hi-Temp Grease or equivalent (see Service Parts on page 13) to lubricate fittings. Lubricate each season or every 25 hours of operation. CHECK AUGER GEARCASE OIL 1. Place unit on flat, level surface. 2. Remove oil fill plug. See Figure 12. IMPORTANT: Wipe each fitting clean before and after lubrication. IMPORTANT: DO NOT remove gearcase cover.
3. Reinstall bottom cover and return unit to operating position. ADJUSTMENTS Auger Shaft 1. Remove shear bolt nuts and bolts. 2. Apply grease at the grease zerks. See Figure 15. WARNING: AVOID INJURY. Read and understand the Safety section before proceeding. ADJUST SCRAPER BLADE The auger housing may be damaged if blade wears down too much. 1. Tip unit back onto handlebar, support auger housing and loosen nuts retaining blade. 2. Lower blade and tighten nuts. 3. Adjust skid shoes.
REPLACE SHEAR BOLTS Replace shear bolts if obstruction stops auger rotation and shear bolts break. See Figure 18. 1 If deflector does not follow full range of travel: 1. Position deflector control in the rear-most position. 2. Adjust nuts on chute cable. See Figure 20. • To adjust deflector lower, loosen lower nut and tighten upper nut. • To adjust deflector higher, loosen upper nut and tighten lower nut. 1 2 1.

Check Attachment Idler Arm Roller Clearance 1 1. Place unit in service position and remove bottom cover. 2. Engage attachment clutch and check the clearance between the frame and plastic roller on the lower end of the attachment idler arm. Roller should be 12.7 mm – 22.2 mm (1/2" – 7/8") from the frame. See Figure 25. 2 3 Measure here. 1. Attachment Clutch Cable 2. Cable Adjustment Barrel 3. Jam Nut Figure 23 5. With the attachment clutch disengaged, make sure auger idler arm lightly touches the frame.
• If there is less than 1.6 mm (1/16") gap, loosen idler adjustment nut and move idler away from belt or pulley. Position idler to achieve a 1.6 mm (1/16") minimum brake pad gap and a 12.7 mm – 22.2 mm (1/2" – 7/8") gap between the plastic roller and the frame. See Figure 26. 2 3 IMPORTANT: If adjustments cannot be brought into specified ranges, see your dealer for repair. Check Belt Finger Clearance See Figure 28.

TROUBLESHOOTING Problem Probable Cause Engine is turned off. Correction Turn engine key to run position. See Engine Key on page 9. Turn choke control knob to on position. See Choke Control Knob on page 9. Open valve. See Fuel Valve on page 9. Fill tank with fuel. See Before Operating Unit on page 10. If engine is cold, press primer bulb two times and start engine. Do not prime a warm engine. See Primer Bulb on page 9. See your dealer for repair. Choke is off. Fuel valve is closed. Fuel tank is empty.
TROUBLESHOOTING Problem Probable Cause Shear bolts are broken. Attachment clutch / brake is not adjusted correctly. Impeller is frozen in place. Ice or debris is obstructing auger. Correction See Replace Shear bolts on page 16. See Adjust Attachment Clutch & Brake on page 17. Move unit to a warm place to thaw. Stop engine, remove key and wait for moving parts to stop. Check for and remove obstruction before restarting.
STORAGE WARNING: AVOID INJURY. Read and understand the Safety section before proceeding. SHORT TERM 1. Run auger / impeller for a few minutes to remove loose or melting snow to prevent impeller from freezing. 2. Tighten all hardware to correct specifications. 3. Inspect unit for visible signs of wear or damage. Repair as needed. 4. Apply a light layer of oil or anti-rust compound on bare metal areas. 5. Prepare fuel system for storage. NOTICE: Ariens recommends using a quality fuel stabilizer in all fuel.
