instruction of hydraulic puller
Hydraulic puller is a new ideal tool to replace traditional puller. It has the characteristics of compact structure, flexible use, convenient carrying and operation, less restrictions on site, etc. It is suitable for various maintenance.
1. Tighten the oil return valve stem clockwise before use;
2. Adjust the hook seat so that the hook can grasp the object being pulled;
3. Tilt the piston starting rod back and forth to move forward steadily, and the hook moves back accordingly to pull out the object being pulled;
4. When using, if the extension of the piston start rod needs to be greater than the effective distance of the hydraulic puller piston start rod, it is necessary to stop when the extension distance is close to the maximum effective distance and release the oil return valve rod to let the piston start rod retracts. After adjusting, repeat steps 1-3 again until the object is pulled out;
5. To release the oil return valve stem, just loosen the oil return valve slightly counterclockwise. The piston start rod gradually retracts under the action of the spring;
6. The force required by the object to be pulled out must be estimated before use, and the appropriate puller should be selected. Do not use overload to avoid damage.
7. The working oil of the hydraulic puller is preferably anti-wear hydraulic oil, and the working oil must be clean.
