DELIVERY WARNING: Improper assembly or adjustments can cause serious injury. Customer Note: If you have purchased this product without complete assembly and instruction by your retailer, it is your responsibility to: 2. Understand all Safety Precautions provided in the manuals. 1. Read and understand all assembly instructions in this manual. If you do not understand or have difficulty following the instructions, contact your nearest Ariens Dealer for assistance.
2. DANGER! 1 2 08000134 OS6610 3 ROTATING PARTS! ONLY use clean-out tool to clear blockages. NEVER use your hands. High speed impeller rotates below discharge opening. Wait for all moving parts to stop before removing clogs or servicing. 3. DANGER! ROTATING PARTS. Keep clear of auger while engine is running. OS2080 Figure 2 OS7015 1. WARNING! Read Owner/Operator Manual. • Read Operator’s Manual. • Allow operation only by properly trained adult, never children.
Check for weak spots on docks, ramps or floors. Avoid uneven work areas and rough terrain. Stay alert for hidden hazards. ROTATING AUGER CAN CAUSE SERIOUS INJURY. NEVER ATTEMPT TO UNCLOG OR CLEAN UNIT WHILE ENGINE IS RUNNING. DO NOT operate near drop-offs, ditches, or embankments. Unit can suddenly turn over if a wheel is over the edge of a cliff or ditch, or if an edge caves in. Read, understand, and follow all instructions in the manual and on the machine before starting.
ALWAYS shut off engine, remove key, and close fuel shut-off valve or drain fuel when transporting unit on a truck or trailer. Use extra care when loading or unloading unit onto trailer or truck. Battery posts, terminals and related accessories contain lead and lead compounds, chemicals known to the State of California to cause cancer and reproductive harm. Wash hands after handling. Follow First Aid directions for contact with battery fluid. Secure unit chassis to transport vehicle.
ASSEMBLY WARNING: AVOID INJURY. Read and understand the entire Safety section before proceeding. WARNING: Dropping or tipping over boxed unit could result in personal injury or damage to unit. 5. Install and tighten all wing knobs and wing nuts on the handlebar assembly and shift rod. NOTE: The handlebar has two height positions. Adjust the handlebar height to provide better operator comfort. See Handlebar Height on page 22 NOTE: Model 926023 ships with the handlebar assembly detached from the unit.
NOTE: After the chute rod has been inserted through the hex hole in the control assembly, placing the unit in the service position (see Service Position on page 19) will ease alignment and installation of the hair pin. 8. Secure the chute rod to the control assembly with the hair pin removed in step 6 using the end hole location as shown in Figure 7. Insert the hair pin with the loop end to the left of the chute rod so the control assembly follows a full range of travel. 1 3 2 2 3 1 4 4 1 1.

If clutches do not engage or disengage properly, adjust or repair before operation (see Attachment Clutch/Brake Adjustment on page 24 and Traction Drive Clutch Adjustment on page 27).
Manual Start 1. Turn discharge chute straight ahead. 2. Make sure that the traction clutch and attachment drive clutch levers are fully disengaged. 3. Push Primer Bulb 2 or 3 times for cold engine. IMPORTANT: DO NOT operate starter more than 15 seconds per minute, as overheating and damage can occur. (If engine does not start, refer to TROUBLESHOOTING on page 31.) 11. Adjust choke as needed. 12. Disconnect power cord from outlet, then starter.
2. 926016, 017, 500, 501: Press down on handlebars enough to raise front of unit slightly off surface. IMPORTANT: DO NOT overload unit capacity by attempting to clear snow at too fast a rate. Use slow speed to clear deep or hard packed snow. 926021, 022, 023: Place the unit in the transport position (see Track Angle (926021, 022, 023) on page 16). Tips for Operation Snow is best removed as soon as possible after snow fall. To clear an area, run unit in an overlapping series of paths.
CHECK DUAL HANDLE INTERLOCK CHECK AUGER GEARCASE Without the engine running, press down (engage) both clutch levers. Release attachment clutch lever. Attachment clutch should remain engaged until traction clutch lever is released, then both clutches must disengage. IMPORTANT: Proper oil level must be maintained. CHECK FASTENERS To ensure adequate lubricant level: Gear cases are filled to the correct level at the factory. Unless there is evidence of leakage, no additional lubricant should be required.
