 PROCEDURE  1} Check the water level in the radiator and top up if needed.  2} Check the engine oil level and top up, if needed.  3} Check the electrolyte level in the battery and top up with distilled water if needed.  4} Insert the key in the main switch  and press fully in and turn the key to the `ON' position.   5} Observe the ammeter  on the instrument pannel. The indicator of the meter will show slightly on the discharge side (-ve side) of the meter and the ignition bulb  will glow red and also the oil pressure indicator  will glow.  6} Observe the fuel gauge . The indicator indicates the fuel in the tank from empty to full. Note down the quantity of fuel in the fuel tank . 7} Depress the accelerator lever fully.  8} Press the starter `button' or turn the ignition key further and crank the engine 9} Release the starter button /key as soon as the engine has started.                    Once the engine starts do not touch the starter switch.  10} If the engine does not star

INTRODUCTION OF FASTENERS i)- All big or small machines are made by joining different parts.  ii)- There are so many methods to assemble the machines parts with each other these are called fasteners.  iii)- The process by which these are assembled is called fastening.  iv)- There are three main methods of fastening: (a) Temporary  fastening , (b) Semi-permanent  fastening , (c) Permanent fastening (a) Temporary Fastening :  i)- This is a type of  fastening  by which different parts of machine can be opened or re-assembled without any damage.  ii)- In this neither job nor fastener is damaged like nut and bolt, key, screw and pin etc. (b) Semi-permanent Fastening:   i)- In this method there is no risk of damage to job but fastener is damaged.  ii)- This system is used where there is a chance of opening of the parts due to some reason, For example soldering and riveting etc is Semi-permanent Fastener. (c) Permanent Fastening:  i)- This is a such type of fastener which becomes part of a ma

SCREW ONLINE NOTES AND MECHANIC DIESEL

  Screw:- i)- Screw is used to joint or assemble two parts.  ii)- Entire body contains thread except head. iii)- Nut is not required where screw is used.  iv)- screw are like bolt. v)- Screw used in wooden work is called wood screw. vi)- Screw used in metal and non-metal are called machine screw. machine screw:- i)- When nut cannot used in assembly in that situation machine screw are used ii)- The component of assembly directly tighten with screw for this thread in component is must. iii)-  Machine screws are used for general assembly work. iv)-  It is manufactured in both COARSE and FINE series. Types of machine screw:- i) There are different types of machine screw used in machine work. 1- Hexagonal Head Screw. 2- Hexagonal Socket Head Cap Screw. 3- Square head Counter Sink Head Screw. 4)- Square Head Screw. 1- Hexagonal Head Screw:- i)-This type of screw is used,when there is no disturbance in the assembly of component. ii)- The head may out from the job surface and machine will work

WHEEL BASE, WHEEL TRUCK AND MEASURING TAPE  Objectives : At the end of this lesson you shall be able to  • define wheelbase  • define wheel track •  state measuring tape, its types and uses. The wheelbase of a vehicle equals the center distance between its front and rear wheels. Wheel/Track : The wheel track of a vehicle equals the center distance between its front wheels.  Measuring tape is a flexible ruler. It is made of ribbon cloth plastic fiber glass metal strip with lines for measurements. It is very common measuring tool used by many people. The available range are 3 m, 5 m and 10 m . Types  1. Plastic Tape   2. Metal Tape  3. Fiber glass  4. Ribbon cloth Application  Dress makers  Civil Engineers  Mechanical Engineers  Surveyors  Carpenters Medical field Accuracy  Measuring tapes are marks in metric and British system. The accuracy in metric system is 1mm and in British system is 1/8”. Limitation: Accuracy is not possible, because the tape is flexible and likely to elongate whi

INTRODUCTION TO 5 S CONCEPT AND ITS APPLICATIONS

Image
  The 5s concept was developed in Japan .it is the is list of five japanese words seiri,seiton,seiso,seiketsu  and shitsuke which means sort,systematic (set an order) shine, standardize and sustain respectively.   1. SORT Remove what is not needed and keep what is needed. Principles: •  Stratification management •  Dealing with the causes Practices: •  Distinguish between the necessary and unnecessary •  Get rid of what you do not need •  "When in doubt, move it out" 2. SET IN ORDER Arrange essential items in order for easy access. Principles: •  Functional storage •  Search elimination Practices: •  Arrange items in order for easy access •  A place for everything •  Everything in its place after use 3. SHINE Keep things clean and tidy; no trash or dirt in the workplace. Principles: •  Cleaning as inspection •  Degrees of cleanliness Practices: •  Eliminate
