At installation use on one axis of the car of a spring with identical technical characteristics (with identical colour marks).
Examine the case and a shock-absorber rod. On the case there should not be mechanical damages, on a rod — corrosion traces. Establish the shock-absorber in vertical position and check up its work, moving a rod at full capacity, and also upwards and downwards on 50–100 mm. In all cases the shock-absorber rod should move smoothly, with notable resistance. If the shock-absorber rod moves jerky or there are mechanical damages, replace the shock-absorber.
The rod газонаполненного the shock-absorber can spontaneously be put forward from the shock-absorber. Absence of spontaneous promotion of a rod from the shock-absorber does not testify to malfunction of the shock-absorber. In this case газонаполненный the shock-absorber continues to work as the hydraulic shock-absorber. The shock-absorber carries out the functions and in the absence of superfluous pressure of gas, but thus there can be an additional noise at piston moving.
Check up absence of leaks absorber liquids. It is supposed small подтекание oils at preservation of normal working capacity of the shock-absorber. If the stain of the liquid which have flowed out from the shock-absorber, extends only to the bottom support of a spring it is considered the normal phenomenon. At insignificant подтекании liquids from the shock-absorber the sealing ring of a rod of the shock-absorber that increases term of its service is greased.
In the presence of strong leaks of a liquid replace the shock-absorber.
Fix the shock-absorber in a vice with soft sponges.

Establish a protective cover and the top support on a rod of the shock-absorber and fix a nut, having tightened its moment specified in specifications.
Establish a forward rack on the car.
