Pay attention to the use of hydraulic wrenches
1. When installing the hydraulic wrench, first tighten the oil return valve stem in a clockwise direction.
2. The working oil of the hydraulic puller should be anti-wear hydraulic oil, and the working oil must be clean.
3. According to the size of the pre-tightening nut, an inner hexagon socket is selected.
4. Insert the high pressure and low pressure hoses with quick connectors into the joints between the wrench and the reversing valve
5. Tilt the piston starting rod back and forth to move forward steadily, and the claw hooks back accordingly to pull out the object being pulled
6. The angle of the connecting rod of the wrench should be controlled within the range of the angle calibrated by the reaction rod.
7. Suppress
8. After preloading, put the handle of the reversing valve in the middle position to make the pressure return to zero.
9. After removing the quick connector, the exposed part of the connector must be covered with a plastic cover;
No matter how good the quality of the hydraulic wrench is, there will be problems after the wrong use. Therefore, in the operation steps of the hydraulic wrench, you must follow the correct operation method and pay attention to the safe operation: in the beginning, people must do it first. The purpose is to determine the loosening action; take out some of the drive square shafts before reversing them; install some related drive square shaft positioners, pull down the reaction arm locking device, and install them in the appropriate orientation. Enter the reaction force arm and determine the direction of the square axis during loosening and locking work.
