What’s In Do you have hand tools at home? Can you identify them? Some of these tools are used in repairing and maintaining electrical and electronics at home. In this module, you will always learn different hand tools and its uses in repairing and maintain computer devices to avoid damage of tools and safety procedures in using tools with appropriate Personal Protective Equipment PPE. Notes to the Teacher 1. Read the lessons properly. These will guide you to do at end of this module. 2. Find out what you already know by taking the learning the activities. 3. Apply what you have learned in another activity or real -life situation. 9 What’s New Activity 1: Andrew loves to help his father, Manong Tony, a technician, in their computer shop. To assist his father, he needs to identify properly the tools in the shop. Let us help identify these tools! 10 Proper Tools and Selection In repairing and maintaining hardware equipment, it is necessary to have a toolkit that should contain all the necessary tools in different types of job. Now, you will learn which tools to use in preparing a task. Common the name of tools and its uses Table 1. Tools and its uses Tools Picture 1. Long Nose Pliers Usually for holding, bending and stretching the lead of electronics component or connecting wire. 2. Wire Cutter Used for Cutting copper, brass, iron, aluminum and steel wires. 3. Flat Head Screwdriver Usually drive or fasten negative slotted screws. 4. Philips Head Screwdriver won’t to drive or fasten positive slotted screws 5. Soldering iron is a hand tool won’t to join two or more metal conductors with the support of soldering lead melted around it. 6. Soldering Stand This can be an easy hand tool stand composed of a heavy-duty metal base and a reinforced spring holder. 7. Soldering Lead could be an alloy accustomed to join together metal workpieces. 11 8. Soldering Flux allows you to supply a clean soldered. 9. Crimping Tool may be a device won’t to conjoin two pieces of metal by deforming one or both during a way that causes them to carry one other. 10. Wire Stripper may be a small, hand-held device that usually strips the electrical insulation from electric wires. 11. Tweezer is a tool won’t to manipulate small parts. 12. Anti-static wrist strap usually safely ground an individual functioning on very sensitive electronic equipment, to forestall the buildup of electricity on their body, which might lead to electrostatic discharge (ESD) Equipment. 13. Multi-tester Usually tests the integrity of circuits and therefore the quality of electricity in computer components. 14. Lan Tester designed to check most network cable wiring. 12 Proper use of hand tools A computer technician is requiring using appropriate tools within the toolkit when repairing computers. Here is the correct use of tools in working areas. Several tools are attracted. When working around electronic devices, take care that the tools you’re using haven’t been attracted. Attractive fields may be harmful to data stored on attractive media. Check your tool by pointing the tool with a screw. If the screw is drawn to the tool, don’t use the tool. 1. Screws. Screws can become exposed if you over-tighten them with a screwdriver. An exposed screw may mire within the screw hole, or it should not tighten firmly. Discard exposed screws. a. Flat head screwdriver. Don’t use a flat head screwdriver to get rid of a Phillips head screw. Never use a screwdriver as a wrecking bar. If you can’t remove a component, check to determine if there’s a clip or latch that’s securing the component in position. b. Philips screwdriver. Use a Phillips head screwdriver with crosshead screws. Don’t use this kind of screwdriver to puncture anything. This can damage the pinnacle of the screwdriver. 2. Soldering iron and stand. Always use a soldering iron stand after you aren’t soldering to avoid burns or damage. 3. Crimping tool and wire stripper. When using the crimping tool and wire stripper, you are doing not to have to squeeze super hard the handle because the aim of it’s just to form a bend within the center of the crimp bead and to insulate the wire. 4. Long Nose Pliers and Tweezer. After using the long nose pliers and tweezer clean it properly with cleaning oil and rugs to avoid them from becoming dull and rust. 5. Multi-tester and Lan tester. Always maintain the functionality and accuracy of multi tester and lan tester to ensure the accurateness of measurement of any things that you just shall measure. 6. Anti-static wrist strap. Always properly check the device before using it to make sure that you just are free from danger and to avoid serious damage to the person engaged in it. 13 Proper Maintenance of hand tools To prevent tools from damage, we must properly maintain our tools to stay them safe and usable condition. Here are the subsequent requirements for tools and equipment maintenance: 1. Obtaining a duplicate of the upkeep schedule recommended by the manufacturer. 2. Ensuring that maintenance is performed as needed. 3. Ensuring that the person(s) performing the upkeep are competent. 4. Retaining records of maintenance/service conducted 5. Specifying who is to blame for overseeing equipment maintenance and where the records are kept 6. Putting in a system for removal and tagging of damaged or defective tools and equipment. To ensure that tools and equipment remain in condition and last for a protracted time, store them properly so it’ll be easy to search out when needed and are less likely to be lost. PPE (Personal Protective Equipment) This is to shield you from hazard that will happened during working time at your workplace. Always wear PPE equipment’s like gloves, safety glasses, protective mask and rubber sole shoes.
