ZEST BOLT Service Manual

GENERAL 2 • For correct reinstallation of fuel lines / vacuum lines attach tag describing the correct positions • Make sure only the branded lubricants, coolant, corrosion protection coatings and sealants are used. • Check all the lines for leaks related to the systems like fuel, oil, coolant, vacuum, exhaust and brakes after servicing. • For vehicles equipped with high pressure fuel injection systems do not disconnect the fuel line between the injector and the fuel pump without releasing the fuel pressure, fuel can be sprayed out under pressure. Precaution for Catalytic Converter (Petrol Engine): Caution: If large amount of unburnt fuel goes into the converter, it may overheat and create a FIRE hazard. To prevent this, observe the following precautions: • Use only unleaded gasoline. • Engine compression checks should be carried out within the shortest possible time. • If necessary then only conduct a spark jump test within the shortest possible time. • Do not run the engine when the fuel tank is nearly empty to avoid engine misfire and damage to catalytic converter. Precaution for Catalytic Converter (Diesel Engine): • The Catalytic converter should not be dropped from a height. If dropped, it should not be used. • Ensure exhaust system and catalytic converters are not blocked and free from obstruction. • Avoid parking of vehicle over inflammable materials, such as dry leaves; grass etc. as exhaust system is hot enough to initiate fire. • Avoid push start or tow-starting the vehicle. (Use jump leads) • Avoid long (not more than 10 seconds) repeat (not more than 3 times) starting of the vehicle. Investigate the cause for difficulty in starting and rectify the same. • Avoid long idling (to warm-up) if the engine is running rough, after a cold start. • Avoid switching “OFF” the ignition when driving down the hill. • Avoid fuel almost empty in the tank. • Avoid pre- coating / painting of Catalytic Converter.
