In this time of machines being bought and sold from bank Repos and Internet sites I would like to ask you to do yourself a favor. If there is an update or info pertaining to a PM unit it is sent to the registered owner, You might be the 2nd or 3rd owner. Please contact the PMA Customer support Group to let us know you are the new owner of a Putzmeister Pump. This will make it easier for us to service and help you in the future. It would be a simple thing to even e-mail or phone your contact info and Serial # for the unit. This can be done at 1 800 890 0269 Or I can forward the info woodsa@putzma.com Please look into this for your fleet. Thanks
