We have just purchased a 2005 Linde H70D-03 that has been speed limited, and it's too slow for our application. A Linde tech advised me that it has been done mechanically (later models are done electronically) and that it could have been done two or three ways, including adjustments on the hydraulic motors. He also said that a Linde tech would need to fix it - he didn't want to tell me how it is done. Trouble is said Linde tech is over 300km away, and will cost a fortune in travel. Anyone got any ideas? Any help much appreciated!
