The anti-icing effectiveness of the propellers decreases with usage over time. Please replace the propellers at least every 12 months or after 500 flight hours.

Do not scratch the surface of the propellers or touch them directly with your fingers. Do not use oil-based or alcohol-based solvents to wipe the propellers, as this may damage the anti-icing layer on the surface.

Each set of propellers is dynamically balanced. When replacing propellers, please use the propellers from the same package and do not mix them with propellers from other packages.

If the propellers become deformed or damaged during use, they need to be replaced promptly. When replacing propellers, be sure to simultaneously replace the corresponding washers and screws. Do not reuse them.
