Troubleshooting Guide - DeWalt D51420 Guide D'utilisation

Compressor will be sufficient for tools at all production rates.
Le compresseur peut actionner tout outil, quel que soit le taux de production.
El compresor será suficiente para las herramientas a todo índice de producción.
Compressor will be sufficient at slow or moderate production rates, but may have difficulty at very rapid rates.
Le compresseur peut actionner des outils à des taux de production faibles ou modérés, mais peut avoir de la difficulté à
des taux très élevés.
El compresor será suficiente a índices de producción lentos o moderados pero tendrá dificultad con índices demasiado
rápidos.
Compressor will be adequate only when tools are utilized at slow production rates (punch-out or occasional use).
Le compresseur ne sera vraiment efficace que lorsque les outils sont utilisés à de faibles taux de production
(p. ex., lors de travaux rapides ou occasionnels).
El compresor será adecuado sólo cuando las herramientas sean utilizadas a índices de producción lentos
(perforación o uso ocasional).
