Ammann have created a list of QR codes which give you direct links to a number of service specific videos, including as shown below, The ACR68 rammer.
You can view and download the selection of QR codes right here on the PDF file.
You can simply scan the code with any QR code scanning app, or alternatively there is the Ammann Service App which holds all the videos and information on. The App is a tool developed for customers to have machine documentation and service support on site at all times.
The tool is also helpful to quickly look up manuals and part lists when a machine is in the workshop.
You can download the app by following these links:

A&Y service manager, Jason Redgrave said the app is "awesome" and is a really helpful tool for anybody running Ammann machinery to have. It's free to install and is continually being updated and improved.
