Why does the platform lifts descend automatically?
1. Reason: One way valve discharge troubleshooting method: check the one-way valve in the valve group. If dirt is found on the sealing surface of the check valve. Clean the check valve.
2. Reason: The lowering valve is not tightly closed. Troubleshooting: check whether the lowering valve is powered on. If not, eliminate the failure of the lowering valve itself or replace the lowering valve. The spool of the lowering valve must be kept clean and move flexibly.
3. Reason: Oil cylinder internal leakage elimination method: replace the oil cylinder seal.
