8 hook pulley should be flexible rotation.
9, the rope should be no obvious defects, arranged in neat rows on a roll, no signs of disengagement pulley groove, good lubrication.
10, hanging aids no abnormal phenomenon.
11, electric hoist working environment temperature -25 ~ +40 ℃
12, electric hoist does not apply to full corrosive gas or relative humidity greater than 85% of the places is not a substitute for explosion-proof hoist should not be lifting molten metal or toxic, flammable and explosive materials.
Second, the European electric hoist shall not be the lateral crane unloading heavy prohibited overload.
Third, during use, the operator should be checked at any time wire rope if Labelling, knotted off slots, wear phenomenon should be immediately removed if there is, and should always check the guide rope and limit switches are safe and reliable.
Fourth, in the day-to-day work shall not be artificially stopper to stop lifting a weight or stop equipment running.

Motor fan on the brake wheel brake ring allowed stained with grease, adjust the nut should be tightened to avoid the accident occurred due to brake failure.
Electric hoist lubrication part shall promptly increase the amount of lubricating oil, lubricating oil to be cleaned, free of other impurities. Lubricants for about two months to replace. Lifting injected into the No. 50 mechanical oil (HJ-50GB443-64) of reducer and run reducer before use must add enough oil, lifting reducer. 0.5t, 1t, 2t, 3t, 5t, 10t electric hoist Note people lkg, 1.5kg, 2.5kg, 3kg, 3kg, 4kg, run reducer injection viscosity of 5.5 to 7 º E50. Quantity 0.3kg lubricating oil.
Nine, the use of the process, the failure should be promptly cut off the main power supply.
Ten, electric hoist does not work, does not allow heavy objects hanging in the air, to prevent parts permanent deformation.
11 electric hoist after use should be parked in the designated place of safety. Should be located outdoors rain cover.
12 prohibiting press the button of two opposite directions at the same time, the other can manipulate.
13, maintenance shall not use a screwdriver when the liter reducer demolished from flat shovel and hit joint surface application of wood hammer gently tap the box protruding part, so as not to damage the box and lid sealing plane.
