GENERAL INFORMATION

The catalyst is a reliable and simple device which does not need in any service, but there are some facts which the owner has to know for the maximum service life of the catalyst.

Do not use ethylated gasoline in the car equipped with the catalyst as lead will cover precious metals in a catalyst lattice, reducing efficiency of their transformation and eventually will put the catalyst out of action.

Always you keep ignition and fuel system in a full order.

If during the operation of the engine admissions of ignition are observed, do not operate the car before malfunction elimination.

If during the operation of the engine the control lamp of engine management lights up, it is necessary to address as soon as possible on service station. If there is an engine management damage, then except increase in fuel consumption and reduction of dynamic characteristics of the engine, the catalyst can fail.

Do not start the engine by a towage method.

Do not switch off ignition on high turns of the engine.

Do not use additive to fuel and engine oil as additives may contain the substances capable to damage the catalyst.

Do not use the car if from an exhaust pipe the trace of blue smoke is visible.

After an engine stop the exhaust system a long time continues to radiate a significant amount of heat therefore it is necessary to avoid the parking of the car on a grass and dry leaves.

Remember that the catalyst is fragile therefore avoid blows at removal of the catalyst or exhaust system.

The catalyst used on well adjusted car has to serve from 100 to 160 thousand km of a run of the car.
