Ion 8 inch 033406 Model Year 2019
Loading Schematic Pages...
Maintaining a 2019 Ion 8-inch electric ice auger (Series 033406) involves a mix of electrical troubleshooting and mechanical upkeep. Because this model relies on a 40V lithium-ion system, safety is the primary concern during any repair.
Safety and Preparation
Before performing any diagnostics or repairs, adhere to these protocols:
-
Remove the Battery: Never work on the auger with the battery connected. This prevents accidental activation.
-
Blade Guard: Always keep the blade protector on unless you are specifically servicing the blades.
-
Work Surface: Use a clean, dry bench. Ice augers are often wet; ensure the unit is wiped down to prevent slipping or short-circuiting electrical components.
Troubleshooting Guide
| Issue | Potential Cause | Solution |
| Motor will not start | Dead battery or poor connection | Charge battery; clean terminals with a dry cloth. |
| Auger stops under load | Battery cold-soak or low charge | Warm the battery in a vehicle/jacket; recharge. |
| Motor runs, shaft doesn't turn | Broken shear bolt or gear failure | Replace the bolt connecting the flighting to the powerhead. |
| Auger vibrates excessively | Bent flighting or loose blades | Straighten the metal shaft or tighten blade bolts. |
| Poor cutting speed | Dull or incorrectly installed blades | Sharpen or replace blades; check mounting direction. |
Electrical System Repairs
Battery Terminal Maintenance
If the auger is intermittent, the issue is often at the contact points.
-
Inspect the copper terminals on both the battery and the powerhead for green or white oxidation.
-
Use a small piece of fine-grit sandpaper or a contact cleaner spray to remove debris.
-
Ensure the battery "clicks" firmly into the cradle. If the latch is loose, the vibration from drilling will break the circuit.
Trigger Switch Replacement
If the battery is charged but the motor doesn't respond to the trigger:
-
Unscrew the plastic housing of the powerhead (typically using a Phillips head or Allen wrench).
-
Locate the trigger assembly. Use a multimeter to check for continuity when the switch is depressed.
-
If there is no continuity, the switch assembly must be replaced as a single unit.
Mechanical Repairs and Blade Service
Blade Replacement
The Series 033406 uses two flat blades and a center point.
-
Use a 6mm Allen wrench to remove the two bolts holding each blade.
-
Note the angle: The beveled edge of the blade must face the ice.
-
Apply a small amount of blue thread-locker to the bolts before re-installing to prevent them from vibrating loose during use.
-
Tighten until snug; do not over-torque, as this can strip the aluminum mounting plate.
Straightening the Flighting
If the auger was dropped and the flighting (the corkscrew part) is wobbling:
-
Lay the auger on a flat floor and rotate it slowly.
-
Identify the high spots.
-
Use a rubber mallet to gently tap the flighting back into alignment. Do not use a steel hammer, as it may chip the powder coating and lead to rust.
Gearbox and Transmission
The 2019 Ion uses a planetary gear system. This is a sealed unit and rarely requires internal repair. However, if you hear grinding:
-
Remove the flighting from the powerhead by removing the hitch pin or bolt.
-
Check the output shaft for play. If the shaft moves side-to-side, the internal bearings may be worn.
-
If the gearbox is compromised, it is generally recommended to replace the entire transmission assembly, as the gears are press-fitted at the factory.
Storage and Long-Term Care
-
Off-Season Battery Care: Do not store the 40V battery completely empty or completely full. Keep it at approximately 50% to 60% charge in a cool, dry place.
-
Rust Prevention: Spray the blades and the bottom of the flighting with a light coat of silicone lubricant or WD-40 before summer storage to prevent surface corrosion.
