★ When the lifting wheel rises to 120mm, the lever will lock against the handle socket. Do not push the handle forcibly at this moment to avoid component damage or safety accidents.
★ Perform a no-load stroke test before track lifting to check whether the lifting wheel can reach the maximum height. Fill with sufficient No.10 machine oil if it fails to reach the limit position.
★ Regularly apply lubricating oil to all hinged joints to ensure flexible rotation.
★ An insulating sleeve is fitted at the rear end of the handle to prevent electric conduction between two rails and shall be properly protected.
