WARNING

Gases/ vapours hazardous to health are generated when welding, soldering or cutting using tools which produce sparks in foam-treated areas.

– Do not weld, solder or cut closer than 15 mm to moulded foam inserts.

– Use an extraction system during work.

NOTICE

If separating cuts are made too deep, underlying reinforcement could be damaged.

– Only make separating cuts with body saw.

– Rewelding of reinforcements is not permitted due to safety reasons.

NOTICE

If welds are positioned too far on outside, strength could be impaired

– RP weld points must be placed as far as possible from outer edge of welding flange.

NOTICE

If adhesive is applied prematurely, bond could be impaired

– New part must be welded in within 90 minutes.
