Ion 11733 ION 8 inch 015945 2013

The ION Series 015945 (Model Year 2013) is the original 40V powerhouse that shifted the industry away from gas. At over a decade old, most issues with this unit stem from battery degradation, switch oxidation, or gearbox grease thickening.

This guide covers the essential maintenance and repair steps to keep this vintage electric auger drilling.

Safety First

Always remove the battery before performing any maintenance on the blades or the drive head. Accidental trigger engagement can cause severe injury.

Phase 1: Power and Battery Troubleshooting

Since this is a 2013 model, the lithium-ion cells are likely reaching the end of their functional lifespan.

• Check the Terminals: Inspect the copper contacts on both the battery and the auger head. If they appear green or dull, clean them with a cotton swab dipped in isopropyl alcohol or a fine electronics cleaner.

• The "Cold Weather" Factor: Lithium batteries from this era struggle in sub-zero temperatures. If the auger cuts out under load, keep the battery inside your jacket or a heated bag until the moment you need to drill.

• Full Discharge Issues: If the charger flashes red immediately, the battery voltage may have dropped below the "recovery threshold." While some specialized shops can jump-start cells, usually this indicates it is time for a 40V ION replacement battery.

Phase 2: Drive Head and Trigger Assembly

If the battery is full but the motor won't turn, the issue is likely the trigger switch or the wiring harness.

1. Open the Housing: Remove the Phillips head screws securing the plastic shroud of the power head.

2. Inspect Connections: Look for wires that have vibrated loose from the motor or the control board. Re-solder any disconnected leads.

3. The Trigger Switch: The 2013 model uses a simple micro-switch. Spray "Electronic Contact Cleaner" into the switch housing and toggle it 20–30 times. This removes carbon buildup that prevents the electrical circuit from closing.

Phase 3: Gearbox Maintenance

The ION uses a planetary gear system. Over time, the factory grease can become contaminated with moisture or harden, causing the motor to strain.

1. Accessing the Gears: Separate the auger bit from the power head by removing the hex bolt.

2. Grease Replacement: If the auger sounds "grind-y" or laboured, the gearbox may need fresh lubricant. Use a low-temperature synthetic grease (standard axle grease will become too thick in the cold and stall the motor).

3. Seal Inspection: Check the bottom seal where the drive shaft exits the head. If it is cracked, moisture can enter the gears and freeze, locking the unit entirely.

Phase 4: The Cutting Head (Blades)

An electric auger relies on "shaving" ice rather than "chipping" it. Dull blades will cause the motor to overheat and the battery to drain prematurely.

• Blade Sharpening: The ION blades have a specific convex grind. It is generally recommended to replace them rather than hand-sharpen unless you have a specialized jig.

• Centering Point: Inspect the small pilot bit at the very bottom of the auger. If this is bent or dull, the auger will "skate" across the ice instead of biting. Straighten it with a pair of pliers or replace it to ensure a straight hole.

• Mounting Bolts: Ensure the two Allen bolts holding the blades are extremely tight. Even a slight wobble will ruin the cutting angle.

Long-Term Storage Tips

The 50% Rule: Never store your ION battery completely empty or completely full over the summer. Keep it at approximately two or three lights (50–70% charge) in a cool, dry place to prevent cell permanent capacity loss.

Rust Prevention: Wipe down the steel auger flutes with a light coat of WD-40 or vegetable oil before summer storage to prevent surface rust from pitting the metal.
