Belt Tensioner Special Notes

Use extreme care when removing and installing belt tensioner units. Handling belt tensioner units improperly is very dangerous and could result in serious personal injury.
Belt tensioner units that are mechanically damaged (dents, cracks) must always be replaced.
The open end of the belt tensioner should never be pointed at anyone.
When connecting a belt tensioner, all mechanical parts, including those in the three-point seat belt, must be secured correctly. If it is not possible to connect the belt tensioner because of insufficient space, the seat belt webbing must be rolled up completely prior to connection. In this case there is no increased safety risk, if all other safety instructions are followed. In particular, this includes the notes regarding the disconnection of the battery and the static discharging of the technician prior to connection of the belt tensioner.
Even after a crash, it is possible that the belt tensioner ignited, but the belt force limiter did NOT. Treat these components as if they had not ignited!
