Hello friends. I have a LINDE H35D-02 (393 series) forklift from the year 2013. When I activate the ignition key, the display shows the code T282. Once the diesel engine has started, the T284 code also appears. The traction and the servo-steering work correctly, but the hydraulic functions (lift, inclination) act slowly except for the lowering movement that works at full speed. Can you give me some guidance on this fault? Very grateful in advance.
