Procedure of dumping of pressure of fuel

Gasoline is inflammable liquid therefore at work with components of a power supply system it is necessary to observe special precautionary measures in the highest measure. Do not come nearer AT ALL to a venue of works with the lit cigaret, open fire or unprotected by the lamp shade carrying. It is not necessary to make power supply system service in the rooms equipped with heating devices, working at natural gas and equipped with a control torch (водогреи, dryers, etc.) . Each time when arises threat of hit of gasoline on open sites of skin of hands, put on latex gloves. Casually got splashes immediately wash away water with soap. The spilled fuel immediately clean by means of rags. The rags soiled by fuel put in such place where there is no probability of its casual ignition. The power supply system constantly is under pressure therefore before starting a detachment of any of fuel lines surely dump pressure in system. Constantly hold near at hand the chemical fire extinguisher of dry type (class B).


 PERFORMANCE ORDER

  1. Disconnect a negative wire from the battery. Uncover mouths of the gulf of fuel, having dumped thereby superfluous pressure in a fuel tank.
  2. Uncover the union of check of pressure of the fuel located on the fuel highway.
  1. By means of a small screw-driver or a small beard wring out Schröder's valve in the verifying union of the fuel pump. Be ready to collecting by rags vypryskivayemy thus fuels (wrap up it a sting of a screw-driver and a valve head).
  1. Wrap up the verifying valve rags (also enclose rags and under it) is is necessary for prevention of a razbryzgivaniye of fuel when opening valve for pressure dumping in system.
  2. By means of a small screw-driver or a small beard wring out a valve head in the verifying union for dumping through it superfluous pressure (see an illustration above). The spilled fuel immediately collect the rags prepared in advance.
  3. Establish a cover on the verifying union of pressure of fuel.
