I can't help other than let you know there is a guy on the forum edward t in north carolina who is very familiar with cat/mitsubishi lifts & very helpful to techs. His email address is in his forkliftaction profile. Surf around and find his name then double click on his name and it should pop up - send him an e-mail. Give him the make, model & serial number of the lift truck in your message - he will always ask for it. s/n on forklifts are important as the build dates on automobiles.
