51 00 ... Notes on fitting window guide seals

1. Work safety when handling anti-friction agent G13*
- Wear protective goggles, protective gloves and if necessary an apron.
- Do not eat, drink or smoke in the area of processing/application
- Ensure rooms are well ventilated.
- Keep heat and ignition sources well away
- In event of skin contact: Wash areas of skin affected with soap and water immediately, change work clothing which has been fouled with anti-friction agent immediately (keep spare work clothing in reserve)
- In event of eye contact: Rinse eyes immediately with plenty of water and seek medical advice
- Observe safety data sheet (see After Sales Assistance Portal (ASAP) - Service/Technology - Safety Data Sheet - 7 digit part number)

2. General notes
- Use only the BMW-approved anti-friction agent for fitting
- Application only at room and object temperatures between 18 and 25°C
- Anti-friction agent dries at different rates depending on the quantity, temperature and ventilation and becomes sticky
- Anti-friction agent can only be used for fitting and not for fault elimination (e.g. grating)
- Newly painted parts may only be brought into contact with the anti-friction agent after cooling
- Optimal bonding/attachment to the background surface is achieved after approx. 48 hours. The window guide seal must not be exposed to mechanical strain beforehand (car wash, strength test, etc.).

IMPORTANT: To avoid grating noises, do not use soapy water (low-surface-tension water with washing-up liquid) or anti-friction agent containing silicone

3. Auxiliary materials and tools
- Spirit, cleaning cloth, plastic squeegee, needle
- Anti-friction agent G13* (manufactured by Zestron) part no. 83 23 0441 032
(*sourcing reference: BMW Parts Service)

4. Preparations
- Heat and remove anti-friction agent residues with a hot air blower or clean new part thoroughly
- Immediately prior to fitting, clean the work area with spirit in order to remove silicone and grease residues

NOTE: Air drying time approx. 1 minute

5. Assembly
- Apply a thin coating of anti-friction agent to the reverse side of the window guide seal only
- Perform fitting within 30 minutes of applying anti-friction agent
- Anti-friction agent dries after fitting and becomes sticky
