All Dynamos and most Jet and revolution machines fit the 60L cylinders. Some do not need any adjustments to fit the 60L cylinder but on many models a small adjustment is needed. Instructions on how to do so are below:

1. Remove the back of your machine.

2. At the bottom of the back of your machine is circular piece, in most machines this piece is grey. Remove this piece, it will come out easily. 

After removing the circular piece the 60L gas cylinder will fit. 

Please note that there may be other models, other than the Dynamo, Revolution and Jet, that require this small piece to be removed.
