FAQ 

Q：When does the control box need replacement?
A: Replace when box deformation prevents proper control valve installation, mounting hole damage causes loose valve fixation, the panel cracks, or severe box corrosion occurs. Continued use may cause control valve position shift and inaccurate handle travel.

Q：Is abnormal gear or working attachment operation always caused by the control box?
A: Not necessarily. Check the control valves themselves, cable travel, oil pressure, and linkage mechanisms first. Inspect the control box for deformation causing valve position shift after confirming control valves and transmission mechanisms are normal.

Q：Can the control box be partially repaired?
A: Minor deformation can be corrected, and local corrosion can be derusted and repainted. When mounting hole damage is severe or box structural deformation affects valve installation accuracy, assembly replacement is recommended.

Q：What to note during control box installation?
A: Confirm the control box model matches the cab mounting position, and organize cable and harness routing before installation to avoid crushing. Tighten bolts to specified torque and check handle travel and control valve operation after installation.

Q：How to maintain the control box daily?
A: Regularly check box fixing bolts for looseness, valve mounting for looseness, and handle travel for normal operation. Keep the control box clean and dry, and address corrosion promptly.
