Note

The use of penetrating fluid, contact spray or grease etc. is prohibited since the missing adhesion in the threads may cause a torque excess and, therefore, the break of the threaded connection.

The grey sanding pads are suitable for light dirt and "soft surfaces". The red sanding pads are suitable for heavy dirt and "hard surfaces".

WARNING

Danger of injury! Observe warning notices and safety regulations → Chapter!

–	Disconnect battery.

Repairing threaded connections

–	Loosen cap nut and remove ring terminal from threaded connection.

Caution

Take care not to abrade excessively the tin coating and ensure that the copper does not appear. This could produce a galvanic cell which destroys metal and causes faulty repair.

Note

As the thickness of the tin coating may differ according to the design, the cleaning process must be performed step by step and a visual check of the ring terminal is necessary between the steps.

–	Check threaded connection and regrind if necessary.

–	Tighten connection and, if necessary, locating element again to specified torque → Current flow diagrams, Electrical fault finding and Fitting locations.
