Notes On Removal/Installation Of Bonded Elements Of Panoramic Roof - AH77.21-P-0001-01A

MODEL ALL 

The side window on the driver door must be open during the adhesive material's curing time.

Otherwise the relevant element of the panoramic roof may be pushed outward by the resulting air pressure when the doors are closed.

If new parts are installed during body repair in the area of the panoramic roof body flange, mask off the bonding surfaces before painting.

Otherwise the strength of the adhesive connection can be impaired and proper adhesion of the adhesive material is not ensured.

Mask off the roof cutout at the side roof paneling and at the front and rear window using suitable duct tape.

Otherwise there is a risk of damaging the vehicle paintwork when cutting out.

The object and room temperature should be min. 15 °C and should not exceed 35 °C.

Otherwise the strength of the adhesive connection can be impaired and proper adhesion of the adhesive material is not ensured.

Only use material from repair kit approved for corresponding vehicle and always observe enclosed processing instructions.

Otherwise the strength of the adhesive connection can be impaired and proper adhesion of the adhesive material is not ensured.

Do not touch bonding surfaces with bare fingers and they should be free of dust, oil, grease, wax and other adhesive components or dirt residues.

Otherwise the strength of the adhesive connection can be impaired and proper adhesion of the adhesive material is not ensured.

The primer must flash off for at least 15 minutes.

Otherwise the adhesive effect of the adhesive material will be impaired.

Apply adhesive only after primer has completely cured.

Otherwise the strength of the adhesive connection can be impaired and proper adhesion of the adhesive material is not ensured.

Ensure that adhesive material is applied only to present adhesive beads, which have been cut down, or to the original factory primer or repair primer approved by Daimler.

Otherwise the strength of the adhesive connection can be impaired and proper adhesion of the adhesive material is not ensured.

Apply adhesive material within 25 minutes and then place the elements of the panoramic roof onto body flange within 15 minutes.

Otherwise the strength of the adhesive connection can be impaired and proper adhesion of the adhesive material is not ensured.

The vehicle must not be moved for at least 10 hours after gluing in panoramic sliding roof frame.

Otherwise the strength of the adhesive connection can be impaired and proper adhesion of the adhesive material is not ensured.

Working on panoramic roof 

• The use of approved materials and tools is absolutely necessary for proper repair because the material characteristics of the approved products influence the work results and labor times.
• Adhesive bonds are a part of the unibody construction. Always exercise particular care when performing work on bonded elements of the panoramic roof.
• Following any fire damage, check the bondings and replace if required, as strong heat can damage the adhesive.
• Clean paint damages in the area of damaged points and treat with anticorrosion agents, and apply paint on the repair point (see guidelines for paint repair).
• Following cleaning and priming, do not touch bonding surfaces.
• Any adhesive residue may only be cut to the required height of approx. 1 to 2 mm just before installation.
• Before the adhesive is applied to painted sheet metal, the gluing point must be cleaned and treated with a primer (bonding agent).
• The vehicle may only be moved again after curing of the adhesive (idle time) (observe manufacturer's specifications for adhesive).
• Protect entire vehicle interior against soiling.
