NOTE:

Do not use rust remover, contact spray or grease because the lack of friction will cause the torque to be exceeded when installing and this will lead to the threaded connection breaking.
The gray sanding pads are for slight contamination and suitable for "soft surfaces". The red sanding pads are for heavy contamination and suitable for "hard surfaces".

WARNING: Danger of injury! Observe warning notes and safety precautions. Refer To Warnings and Safety Measures !

Loosen the cap nut and remove the wiring eyelet from the threaded connection.
Check the wiring eyelet for corrosion, contamination, etc.
Select the corresponding adapter and the corresponding sanding pad.

NOTE:

The sanding block can be used instead.

CAUTION: Ensure the tin layer is not worn down too much and the copper is not visible. A galvanic element can form from this, destroying the metal and causing incorrect repairs.

NOTE:

Due to the different thicknesses of the tin layer, the cleaning process must be performed in several steps and a visual inspection of the wiring eyelet between steps is necessary.
