To make the descent of the piston, just use the slotted end of the oil return handle counterclockwise slightly loosen the stem, piston rod that is slowly declining. If the load is not too fast oil return valve stem rotation, or the rate of decline too great a risk. Must estimate the weight of the object 4. Before lifting, remember to use overloading. 5. When using an object must determine the center of gravity, select the jack focal point jack quality, place a smooth, but also must consider the hardness of the ground, should be tough wood jack pad to produce skew even when dumped to prevent lifting. 6. After heavy top, the weight should be in place under the pad to tough wood (or other material) support, just in case the jack failed and dangerous. 7. If several jacks with lifting speed should keep pace, and each jack load should be balanced, and will cause the dumping of dangerous. 8.

Jack must maintain adequate working filtered clean oil will be less than otherwise rated lifting height. 9. Avoid sharp shock. Hydraulic jack at the lifting operation, to select the appropriate tonnage hydraulic jacks: not overload the carrying capacity, choice of hydraulic jacks carrying capacity must be greater than 1.2 times the weight of gravity; hydraulic jack minimum height appropriate, in order to facilitate removal, use hydraulic jacks The minimum clearance height and weight should be at the bottom urging adapt the process when landing pad support heavy sleeper, hydraulic jack lifting height greater than the thickness of the sleeper of sleepers and deformation.
