★ When the lifting wheel rises to 120mm, the lever will be locked with the handle socket. Do not push the handle forcefully at this time to avoid component damage or safety hazards.
★ Conduct a no-load stroke test before track lifting to check if the lifting wheel can reach the maximum height. Fill sufficient No.10 machine oil if it cannot.
★ Regularly apply lubricating oil to all hinged joints to ensure flexible rotation.
★ An insulating sleeve is mounted at the rear end of the handle to prevent electric conduction between two rails and shall be well protected.
