CAUTION
Non-compliance with safety data sheets
Injury due to skin, eye and respiratory tract irritation.
► Read the appropriate safety data sheets before working with 634A58
isopropyl alcohol, 636W145 adhesive and 636P4 primer.

INFORMATION
Inspection for contamination or damage
Check the following points after removing the protective cap:
► Condition of the groove (a) in the housing (Gummikappe abziehen).
► Penetration of foreign bodies in the area around the release button.
The protective cap is not a seal to prevent the penetration of liquids, but pro­
tects against coarse contaminants (mud, sand etc.). If the protective cap
comes loose during the service life or if the cap is damaged, it has to be
replaced with a new protective cap.
