Hi, I´ve got a BT CBE 15 T (2001) with triplex mast and double cilinder on center. The problem is when I lift only the forks in the first part, the forks down slowly, but I lift a pallet the forks no down. Also I lift only the forks and second part of mast and down the forks to first part of mast, the forks don´t down. Could you help me?. Thanks in advance.
