Waydoo Subnado Quick Start Manual page 2

Grease
The controller connector is designed to prevent water from entering the connector port. Moisture
presenting in the connector port may cause: 1. The motor to run nonstop when the Subnado is switched
on. 2. Nonconductive connector or even permanent damage to the Subnado due to corroded connector
pins or contacts. Therefore, keeping the connector port dry is critical to using the Subnado.
Please carefully read and follow Waydoo's official checklist and maintenance notes to ensure optimal user
experience and product longevity.
Before connecting the controller, please check:
(1) If water is present in the connector. Please wash the connector with running fresh water, clean it with
cotton swabs or paper tissue, and air dry before use.
(2) The amount of grease applied to the connector. If insufficient, please add 2-3mm of grease to the
connector, plug and unplug multiple times to spread the grease evenly, and ensure the connector securely
plugs into the port. Please remove excess grease to prevent insecure connection.
(3) Signs of wear and tear on the connector port O-ring. To maintain waterproofness, please replace the
damaged O-ring and make sure it is sufficiently greased.
Notes:
1. If the Subnado is irresponsive after grease application, please consider the following causes and fixes:
(1) Cleaning the corroded copper contacts, if any.
(2) Too much grease to install in place.
(3) Replacing the wired controller if the connector pins are corroded.
2. Please check and apply grease to the O-rings around the waterproof cover to maintain waterproofness.
3. Please unplug and check the wired controller after each use. Please clean and dry the connector if
moisture is present inside.
