In order to ensure every lifting electromagnetic that HVR magnetic design and manufacture with good performance, before the lifting electromagnetic leaving the factory, the necessary commissioning and trial running test that concern lifting electromagnetic must be in strict accordance with European Technical standard .

1. Before observed the electromagnetic device without any exception, ensure the control cabinet power cord, control lines, and other operating device handle both in the initial state

2. put the control switch in the operation box to work position while work man in the operation room

3. when worker operating crane to put the lifting electromagnetic on the material, set the operation box excitation switch to the excitation position, while the current reaches the maximum ，worker can operating cranes to lifting material slow and smooth.
Note: When lifting electromagnetic being put on the material, pay attention to the balance of the center of gravity of the matter being sucked

4. in order to lifting material safe and fast, the worker should operating the crane up and down, move around to observe the lifting of the matter being sucked, without exception, after that , put the operating box excitation switch to the demagnetization position, to lay down the material being sucked and repeated lifting and discharge steps many times, if no exceptions, the lifting electromagnetic can be normally used.

5. in regard to the control cabinet with power outage protection magnetic function , our company advise user to put blackout magnetic function test after completing the above step test , while lift objects being sucked , put the main circuit breaker, if no exception occur, then the lifting electromagnetic function is normal and can normal usage.
