Operating Instructions for the Hydraulic Rail Lifter/Line Adjuster
⚪ For Lifting: Place the machine beneath the rail base, ensuring the rail base contacts the lifting wheel and the rail base side contacts the limit stop. (For Line Adjustment: Place the machine beneath the rail base, ensuring the rail side contacts the lining stop.) Then, lower the carrying beam and close the oil return valve.
⚪ Operate the pumping lever to actuate the oil pressure rocker arm. Stop the lifting/lining operation when the piston rod extends to the visible safety warning line.
⚪ Once the desired lifting/lining height is achieved, stop pumping. Press the oil return handle to retract the piston into the cylinder, resetting the working cylinder. The lifting/lining task is now complete.
