Please insert this bulletin into the "Technical Bulletins" section of your Bosch Parts Manual,
only after making any additions or notes to your Illustrated Parts List(s).
Please be advised that a new dust bag is now available for the above listed models. Part Number
2605 411 023 (dust bag assembly 754) replaces 2605 411 096 (dust bag assembly 754) for these
models only, and eliminates the need for 2605 702 029 (elbow 655). The new dust bag helps reduce
static build up and should be used in situations where static shock is an issue. The old dust bag and
elbow will remain available and can still be used if preferred by the customer.
