Common questions about manuals, registration, and support for this brand.
Before starting, absolutely ensure the power source is disconnected. Follow the exact wiring diagram specific to your controller model provided in the manual, accurately matching the phase, throttle, lock, and battery inputs to prevent electrical shorts.
Yes, most YIYUN pneumatic shock absorbers feature adjustable force settings. You can use a pressure regulator to safely fine-tune the dampening characteristics within the recommended operating range (often 0.1-0.8 MPa based on the model).
Common issues involve miswired connections or an incompatible motor phase. Carefully cross-reference the color-coded diagram in the YIYUN manual. Furthermore, confirm that your motor is correctly rated for the controller's wattage (e.g., 350W/500W/1000W).
Routine maintenance involves routinely inspecting connecting points and rubber seals for wear or air leakage. It is recommended to perform periodic pressure checks, clean pneumatic line filters to prevent clogging, and lightly lubricate external mounting points.
