The drive system consists of a friction disc, drive belt, and traction control. Access requires removal of the housing cover.
Drive Belt Inspection: Check for cracks, glazing, or wear. Tension should allow 1/2 inch deflection at midpoint.
Friction Disc: Inspect for wear or glazing. Replace if thickness is below specification or surface is shiny/slippery.
Traction Control Cable: Adjust so drive lever fully engages and disengages the drive. Cable should have slight free play when released.
The auger assembly includes two steel augers connected by a shaft and shear bolts.
Tip: Always replace shear bolts in pairs with genuine Ariens bolts. Do not use standard hardware bolts.
Primary controls: Drive engagement lever, speed selector, chute rotation crank, and chute deflector.
WARNING! Cables must be properly adjusted to prevent unintended machine movement or auger rotation.
Includes electric starter, ignition switch, and safety interlock system.
Electric Start: Check battery charge (if equipped), clean terminals, inspect wiring for damage.
Ignition System: Test spark with spark plug tester. Check ignition switch and safety interlock switches for continuity.
Safety Interlock System: Prevents engine start unless drive and auger controls are disengaged. Test operation regularly.
| Symptom | Possible Cause | Corrective Action |
|---|---|---|
| Engine will not start | Fuel, spark, or safety switch | Check fuel level and freshness, inspect spark plug, verify safety interlock engagement. |
| Loss of traction/drive | Drive belt, friction disc, cable | Inspect drive belt for wear, check friction disc condition, adjust drive cable. |
| Auger does not turn | Shear pins, auger belt, cable | Replace broken shear pins, inspect auger drive belt and tension, adjust auger cable. |
| Excessive vibration | Loose parts, damaged auger | Tighten all bolts and hardware, inspect auger for damage or imbalance. |
| Poor snow discharge | Worn paddles, low engine RPM | Inspect auger paddles for wear, ensure engine is running at full governed speed. |
Reset: For safety interlock issues, ensure all controls are in neutral/off position.
