3. Wait for all moving parts to stop before leaving operator’s position.

START ENGINE

1. Position discharge chute in a safe direction. See Position Discharge Chute on page 11.
2. Move engine switch to ON position.
3. Electric Start Models Only: Connect a power cord to power cord receptacle and then plug cord into a wall outlet.
   • CAUTION: Use cord that is minimum of 13 amp, 16 Gauge, 3 wire grounded plug, UL listed, CSA Certified. Cord must be labeled suitable for outdoor use.
4. Open fuel valve.
5. If engine is cold, turn choke to CLOSED position.
   • IMPORTANT: Do not apply choke to a warm engine.
6. Push primer bulb twice.
   • IMPORTANT: Do not push primer bulb to start a warm engine.
7. Electric Start Models Only: Press electric start button. If engine does not start after three attempts, see Troubleshooting on page 18.
8. Electric Start Models Only: When engine starts, disconnect power cord from wall outlet, then disconnect cord from power cord receptacle.
9. Recoil Start: Pull recoil starter handle.
   • a. Grasp handle and pull rope out slowly until it pulls harder.
   • b. Pull handle firmly and quickly with a rapid, continuous full-arm stroke. Repeat until engine starts. If engine does not start, see Troubleshooting on page 18.
   • c. Let handle rewind slowly after engine starts. DO NOT let handle snap back against handlebar.

POSITION DISCHARGE CHUTE

IMPORTANT: Always throw snow in a safe direction, away from people and windows.

IMPORTANT: If chute becomes frozen and does not turn correctly, take unit into warm area until controls are unfrozen.

OPERATE UNIT

1. Rotate discharge chute and move deflector to desired positions.
   • NOTICE: On some surfaces, auger paddle rotation may leave residual paddle material. This usually washes off after rain showers. Scraper bar may be adjusted to minimize this condition. See Adjust Scraper Blade on page 15.
2. Pull auger control bar back to handlebar to start auger; release bar to stop auger. See Figure 9.

STOP ENGINE

1. Release auger control bar.
2. Turn engine switch to OFF position.

TRANSPORTING UNIT

1. Stop engine, remove key and close fuel valve.
   • NOTICE: Use extra care when loading or unloading onto truck or trailer. DO NOT lift using discharge chute handle.
2. Secure unit chassis to transport vehicle. Never secure from rods or linkages that could be damaged.

FOR BEST PERFORMANCE

• For complete snow removal, walk slowly and slightly overlap each path previously taken.
• Position discharge chute downwind when possible.
• Do not pick up gravel and rocks. Push down slightly on handlebar to avoid picking up debris.
• Inspect auger before each use and remove any accumulation / debris.
• Check oil level before each use.
• Clean unit after each use.

MAINTENANCE

WARNING: AVOID INJURY. Read and understand the Safety section before proceeding

Proper maintenance can prolong the life of unit. The Maintenance Schedule on Page 12 shows the recommended service schedule. Your Ariens dealer can provide service and adjustments to keep your unit operating at peak efficiency. Contact an authorized engine manufacturer’s service center for engine service. More frequent service may be required due to working conditions (heavy loads, high ambient temperatures, dusty conditions, or airborne debris).

See the maintenance instructions in the Engine Manual for additional information.

MAINTENANCE SCHEDULE

*Refer to engine manual for instructions.

Replace when damaged or when scraper blade has been adjusted down as far as possible and does not touch surface or clear properly. Scraper blade MUST be replaced when worn through to wear indicator pockets. See Figure 10.

NOTICE: DO NOT allow scraper blade to wear down too far or auger housing will become damaged. See Replace Scraper Blade on page 15.

CHECK BELT WEAR

Adjust auger cable as needed. Replace when damaged or when auger stops or stutters during operation. See Adjust Auger Cable on page 14 and Replace Belt on Page 15.

SERVICE & ADJUSTMENTS
