Overall Hydraulic Puller Two-Jaw Three-Jaw YL5T 10T 30T 50T Pulley Wheel Puller Bearing Removal Horizontal Use
F eatures:
2/3 claw interchangeability for versatile site selection.
Detachable handle and 360° pressure direction design for easy operation in confined spaces.
Resilient center pin ensures precise positioning.
High-strength alloy steel forged claw hooks and brackets resist deformation.
Solid steel hydraulic cylinder with monoblock construction delivers high safety factor.
Quick-adjust positioning nut saves time and effort.
I nstruction Manual
1. When using, first insert the slotted end of the handle onto the return valve stem and tighten the stem clockwise.
2. Adjust the claw base to position the claw hook to grasp the object being pulled.
3. Insert the handle into the lever hole and move the piston starter rod back and forth. As the rod advances smoothly forward, the claw hook retracts correspondingly, pulling out the object.
The piston actuator rod of the hydraulic jack has an effective stroke of only 50mm. Therefore, during operation:
4. The extension distance must not exceed 50mm. If the object is not pulled out, stop, loosen the return valve to retract the piston actuator rod, readjust, and repeat steps 1, 2, and 3 until the object is fully extracted.
5. To retract the piston starter rod, simply use the handle's slotted end to slightly loosen the return valve stem counterclockwise. The piston starter rod will gradually retract under spring force.
6. Before use, select the appropriate tonnage hydraulic puller based on the object's outer diameter, pulling distance, and load capacity. Never overload to prevent damage.
7. This hydraulic jack operates between -5°C and 45°C using N15 mechanical oil (GB443-84). For use between -20°C and -5°C, use synthetic gear oil (GB442-64).
8. To prevent tool damage from overload, the hydraulic system incorporates an automatic overload relief valve. When the load exceeds the rated capacity, the relief valve automatically discharges pressure. In such cases, select a hydraulic jack with a higher tonnage rating.
9. As this machine uses oil as its medium, proper maintenance of both the oil and the tool is essential to prevent clogging or oil leakage, which could impair performance.
10. New or long-idle hydraulic jacks may exhibit slight piston rod jerks during initial operation due to trapped air in the cylinder. Perform 2-3 no-load reciprocations to purge air from the chamber. For jacks stored long-term, seals may harden from prolonged inactivity, reducing service life. Therefore, perform 2-3 no-load reciprocations monthly when the jack is not in use.
