How to Fix / Troubleshooting
Safety first: Turn OFF the mower, remove the battery, and dry the exterior before opening the housing.
- Dry the unit: Move the mower indoors to a dry, warm area. Remove the top cover and allow internal components to air‑dry for 24 hours.
- Inspect seals: Check the rubber gasket around the display and top cover. Replace any flattened, cracked, or missing seals with NAC originals.
- Check housing for cracks: Examine the plastic around the display and buttons. Replace the top cover if cracked.
- Reassemble correctly: Ensure all screws are installed and tightened evenly to compress the gaskets properly.
Warning: Do not use a hair dryer or heat gun directly on electronics; excessive heat can cause damage.
