Presence of well equipped worker of the platform on whom there has to be enough place for placement and storage of the car is of extremely great importance. The platform has to be rather spacious for placement on it of the car, a strong workbench / the assembly stand, and also necessary materials and the equipment. An optimal variant is the big garage or the covered workshop. As a last resort just flat platform with an asphalt or concrete covering will approach.

It is necessary to take care also of the place equipment for storage of the components removed from the engine, the tool and other materials. Best of all the easy folding rack with rather wide regiments will be suitable for this purpose.

If extraction of the engine is made by the amateur mechanic for the first time, it is necessary to get support of more skilled companion. In time the given council will allow to save time and to minimize risk of getting injured or damage of the components/equipment.

At absence in private use of the lifting equipment before hiring the winch, try to perform beforehand all necessary preparatory work for the purpose of the maximum reduction of term of rent, and, therefore, and the material inputs connected with it.

Prepare that you should refuse use of the car on refusal of use of the car for quite long time. Performance of a part of the procedures demanding high qualification of personnel and use of the special equipment should be charged to specialists of car service. Remember that automobile repair shops usually have very busy schedule of loading, and therefore it will be reasonable to see to it and agree about terms of implementation of your order in advance.
