Sample questions

1. Fire hazard would be the greatest in case of improper maintenance:

   • of vehicles with diesel engines
   • of vehicles with engines burning petrol or propane-butane gas

2. In order to avoid injury when working on rotating components, repair of the engine is performed:

   • with the engine running and the clutch disengaged
   • with the engine running and the clutch engaged but with the transmission switched to neutral
   • with the engine and the vehicle stopped

3. Mechanical jacks used for partial lifting of a vehicle:

   • must be fitted to special beds formed in the frame, bumpers or other suitable places
   • may be attached to the frame or the axles without any special beds designed for such a purpose
   • are attached to the most convenient place

4. When charging the engine or the vehicle with fuel or oil:

   • there is no danger when working in the presence of an open fire (flame)
   • it is not allowed to work in the presence of open fire (flame)
   • there are no bans, instruction and recommendations regarding work in the presence of open fire (flame)

5. When working on a vehicle lifted by a jack:

   • the vehicle clutch is disengaged
   • the parking brake is engaged
   • the transmission box is switched to direct gear

6. With the engine running, the removal of a high-voltage cable of the ignition system and bringing it close to the vehicle “mass” near components of the fuel system is:

   • forbidden, as the resulting spark may cause a current shock or fire
   • necessary, in order to check the presence of high-voltage current
   • compulsory, in order to check the serviceability of the ignition system

7. The following items may represent a danger for the driver during maintenance and servicing the vehicle:

   • the rotating components of the internal combustion engine
   • the chemical processes in the accumulator battery
   • the processes related to the air-fuel mixture formed in the carburettor

8. When opening the cap of the cooling system radiator at a coolant temperature above 70 degrees, there is a danger of:

   • evaporation of the coolant
   • cooling of the coolant
   • flushing and burning with hot coolant

9. The insulation of the ignition system cables must be maintained in a good state, as the occurrence of a spark in the open increases the danger of a current shock or fire.

   • correct
   • incorrect

10. In case of fire in the vehicle, it should be extinguished:

    • by cutting off the access of air to the fire
    • by improving the access of air by increasing its speed
    • by improving the access of air by increasing its pressure
