C) Checking Water Cooling; D) Greasing The Drive Shaft - Reely Black Rocket X V2 Bedienungsanleitung

c) Checking water cooling

Turning propeller draws water into the tube on the rudder blade holder, causing the motor and speed controller to cool
down. The water is pushed out on the right-hand side of the hull, which can be seen clearly while driving.
Before using the model boat, check that the water cooling system is working properly. To do this, use e.g. a small
piece of hose to blow air into the water cooling inlet. The air blown must come out of the outlet. Also check the model
boat hoses for damage or kinks.
Never operate the model boat with a faulty water cooling system. This can lead to overheating and cause
damage to the motor and the speed controller, which will void the warranty/guarantee!

d) Greasing the drive shaft

The drive shaft must be greased on a regular basis. Lu-
bricate the shaft when the amount of water that leaks into
the hull is higher than usual and/or when the motor makes
an unusual noise.
We recommend removing the drive shaft after about
2 - 3 hours of operation.
First completely unplug the drive battery from the speed
controller.
The connection between the motor and the drive shaft
must be loosened using two 8 mm open-ended spanners.
Then pull the drive shaft out backward.
Clean the drive shaft and apply a thin layer of biodegrad-
able grease on it.
After that, reassemble the drive shaft in reverse order.
Make sure there is a 0.5 mm gap between the plastic
washer and the shaft holder.
