1 .Use only recommended oils and lubricants. Use of thicker engine oil for higher engine oil pressure only reduces engine life.

2. Always use recommended antifreeze agents in cooling system to avoid deterioration of engine components due to corrosion. After filling coolant, fit radiator cap firmly, to keep cooling system pressurized.

3. Maintain correct tyre pressures to ensure better tyre life.

4. Always fit genuine radiator cap to keep system pressurized at predetermined values.

5. New tyres do not give maximum grip straight away and should therefore be run-in at moderate speeds for first 100 kms. This will help to make the tyres last longer.

6. New brake linings must always be run-in, they do not have the optimum friction properties during the first 200 kms. Make sure use asbestos free brake lining as per Govt. Environmental regulations.

7. Avoid mixing of different grades of lubricants or brake fluids during top up.

8. Idle the engine for 3 to 5 minutes before moving the vehicle and stopping the engine to avoid turbo charger from oil starvation.

9. Always start moving the vehicle in first gear.

10. Operate the vehicle in correct temperature range i.e., between 60 deg C and 100 deg C

11. Operate the engine with correct oil pressure and temperature.

12. Daily maintenance is to be regularly performed especially on water separator, coolant level and engine oil level always do refit the water separator drain knob during filter replacement.

13. Avoid cranking of engine for more than 30 seconds. A gap of 2 minutes should be left between successive attempts.

14. Drive judiciously, using rpm meter as a guide. The engine speed should be in green band at all times for economical and comfortable driving. Green band indicates the engine torque RPM range i.e, 1400 to 2000.

15. Check battery every week and top up wth distilled water, if necessary. Keep battery terminals clean and cable joints tights. Apply vaseline / petroloeum jelly on terminals.

16. Watch service indicator of dry type air filter. If it shows red band in engine stopped condition replace primary cartridge and reset the service indicator by pressing the reset button.

17. Observe correct polarity while connecting alternator to battery. Do not check battery condition by sparking the terminals.

18. Do not use kerosine as fuel, adultrated diesel may reduce engine and fuel pump life. We strongly recommend use of diesel comforming to emission standard specification (Euro II / Euro III)

19. Do not use clutch pedal as a foot rest while driving. This will cause premature clutch lining wear and higher fuel consumption.

20. Do not coast vehicle, i.e, drive with engine switched off. This is dangerous for the safety of vehicle and affects the life of gear box.

21. Do not over or under inflate tyres. This reduces tyre life. Watch Tyre wear and relocate tyre by rotation as per recommendation of tyre manufacturer.

22. Do not top up radiator by pouring cold coolant in to hot engine.

23. Do not overfill engine oil in the sump. This may cause engine smoking and high engine oil consumption.

24. Do not keep starter switch key turned after the engine has fired. Release it immediately. Do not turn starter switch key when the engine is running. This will damage the starter pinion or flywheel ring gear.

25. Do not move vehicle before air pressure is built above 5.6 bar and hand brake is completely released, i.e, Hand Brake indicator light and beeper are off.

26. Do not run the alternator without battery or disconnect any lead of alternator while the engine is running.

27. Do not flash the alternator leads to check for current flow. Switch off main line switch when carrying out welding on the vehicle.

28. Do not mask head lamps lens (top 1/3 or top 1/2 portion) with black paint. If done, this will reduce head lamp light intensity.

29. Do not keep the engine at full throttle during engine cranking, keep the engine at idling till the oil pressure builds up.

30. Do not clean exposed painted surface or wind screen with petroleum products i.e, diesel, kerosene and petrol etc.

31. If the red band of service indicator reappears even after cleaning replace primary filter cartridge also.

32. If the air filter primary cartridge is replaced, destroy the old cartridge to prevent its reuse.

33. Ensure that air intake hose, coolant hose are free from punctures, cuts and damages.

34. Replace the secondary cartridge of air filter after three replacement of primary cartridge.

35. Do not clean the secondary carridge. Only replacement is recommended.

36. Always use seat belt while driving the vehicle for your safety.

37. Do not use mobile phone while driving for safety of yourself and other road users.

38. Do not adjust the seat while driving.

39. Do not run over speed on road hums, speed breakers or open man holes on road to prevent strain on air suspension parts.

40. Do not run A.C. compressor without switching on A.C. Blower

41. Do not keep luggage door, passenger door open when moving or driving the vehicle.

42. Do not operate wiper blades on dry wind screen without switching on wind screen washer nozzles.

43. Do not use direct wire link between fuse terminals instead of properly rated transparent fuse.

44. Do not use service brakes on prolonged down gradients, instead use lower gear's and engine exhaust brake.

45. Do not press clutch when applying engine exhaust brake. Switch off isolater switch when engine exhaust brake is not warranted.

46. Do not operate the bus with deflated air bag or wish bone resting on mechanical stoper's.

47. Do not use remoulded tyres in the front wheels.

48. Do not jack up the vehicle other than specified location on the structure.

49. Do not use higher wattage bulb for head lights to get brighter illumination.
