RAM FLAT Customer Support

What is your Serial Number?

When contacting S&G about your machine, please provide the machine’s Serial Number.  This is a 5 or 6-digit number on an aluminum nameplate located in the general area of the main control box.  This nameplate will include the Serial Number, the Model Number and the service voltage. The manuals will also reference the serial number. Don’t have it? Send an email or, better yet, give us a call along with your contact information and we should be able to figure it out.

Free Technical Support

Free phone support is available to all RAM FLAT customers by calling 1-888-RAM FLAT.  Questions can also be answered by sending an e-mail to service@ramflat.com.

Each hydraulic RAM FLAT Compactor or drum crusher was shipped with a supply of hydraulic fluid and a corresponding MSDS (Material Safety Data Sheet).  Several brands of oil have been used over the years. Older machines may not have the original oil in the reservoir – so if you don’t have any notes, we won’t necessarily know what you have either. We do recommend you replace your oil using one of types listed below that correspond to your particular RAM FLAT model. You might try going through a local lubricant supplier to buy or cross match with the original oil. You can also buy the oil from us by going to the Order Online page.
