Keep your electric tools stored in their original cases and containers. This will keep them free of dust and dirt while they are not being used. What is It Let’s continue learning!! In checking the conditions of tools and equipment, be familiar with the classification of tools in checking their conditions if it is functional or not. “It makes or breaks you.” Some Classification of Tools and Equipment. A tool is a device that can be used to produce an item or accomplish a task, but that is not consumed in the process. It can be considered as extension of the human hand thus increasing speed, power, and accuracy and on the other hand equipment includes any machine powered by electricity. A. Electrical Power Tools- are tools that eliminate the need for manpower and training that hand tools require. They do their job quickly, accurately and consistently, allowing you to focus on the job at hand instead of worrying about whether or not your tool will function correctly 1. Electric drill has an electric motor that drives a chuck. The chuck has jaws that can be opened and then closed to grip a drill kit. 2. Grinding tool can be either bench-mounted or installed on a pedestal. They may either have a grinding wheel, view wheel, or two grinding wheels. 4 2. Angle grinder is a handheld power tool that is used for cutting, grinding, and polishing. Also known as a disc grinder, angle grinders are powered by electric motor, petrol engine or compressed air. 3. Zig saw is a tool consisting of a hand blade, wire or chain with a toothed edge. It is used to cut through relatively hard material, most often wood. The cut is made by placing the toothed edge against the material and moving it forcefully back and forth. B. Hydraulic Tools are hand - operated machine with hydraulic drive that is employed for various technological operations such as tightening threaded joints and pressing in and out parts. 1. Pipe blender is designed to bend mild steel pipe. Makes smooth, wrinkle- free bends. 2. Jack hammer is a pneumatic or electro-mechanical tool that combines a hammer directly with a chisel. Classification of Non-functional and Functional tools Tools are very useful to us in our homes especially to our job. But tools that are no longer functional may cause harm. a. Make an inventory of functional and non-functional tools 5 b. Classify your tools according to is function. Procedures of identifying non-functional tools and equipment 1. Visual inspection. It refers to the visual observation of an expert on the appearance of the tools and equipment. 2. Functionality. Vibration or extra noise from the operation means problems on parts and accessories started to develop. 3. Performance. When there is something wrong with the performance of either hand tools or equipment, they need an immediate repair or maintenance. 4. Power supply (for electrically operated only). Failure to meet the required power supply, malfunction will occur in the part of hand tools or equipment. 5. Person’s involved. It refers to the technical person who has the knowledge and skills about the technology. Non-functional tools and equipment are those that are not able to perform its regular function because of impaired and damage part. Study the sample checklist if the tool is operational or defective. Functional tools and equipment are those that are in good condition and can perform its regular functions. Below is a sample form which you may use if you will be tasked to classify tools and equipment into functional or non-functional SAMPLE FORM Parts to be checked Functional Non-functional *Put a check if its parts are functional or non-functional A. MECHANICAL PARTS: a. chuck a. bearing b. rotor shaft B. ELECTRICAL PARTS: a. switch b. line cord c. carbon brush d. rotor winding e. stator winding Working Safely with Hydraulic Systems Basic principles in operating the hydraulic systems A hydraulic pump is used to create the flow of an incompressible fluid. Pressure can then be generated on a surface by restricting the flow of a fluid. 6 If actuators (such as hydraulic cylinders) are placed in the flow of fluid, pressure will be exerted on the piston of the cylinder, resulting in a mechanical movement of the piston. As a result, this mechanical movement allows for the lifting, lowering, expansion or retraction of heavy loads, with greater control and force. Before working on any hydraulic system, always assess the task you are going to do for potential hazards and danger. This is especially important if attempting a task for the first time or if you are unfamiliar with the circuit or system/equipment. If you are unsure, seek training from competent and experienced professionals before working with any hydraulic system. When operating hydraulic power tools: ALWAYS wear appropriate personal protective equipment. Do NOT exceed the rated pressure or force capacity of the equipment. NEVER use equipment with hoses that are kinked or bent. ALWAYS ensure that tools are well maintained and regularly serviced before use. When used safely and in the manner for which they are designed, hydraulic systems and tools are a valuable and effective means of utilizing hydraulic force to lift, pull, extend, tighten, open close and more. ALWAYS take care to observe safe working practices when handling hydraulic equipment and if unsure about any aspect of the work, ALWAYS consult a trained professional. Basic Maintenance of Electrical Tools and Equipment To ensure that your electric tools work when you need them, you must take proper care of them. A good routine of maintenance for your tools is one thing that you can do to make sure that the tool you need is working when you need it. 1. Clean out the Dust. To make sure that your electric tools are ready to go when you are, keep them clean and free of dust. Spend some time to clean out the dust every once in a while, on your tools while they are inactive in storage. 2. Check the Cords. Look for tear/cut insulator on the power cords on your electric tools. This will ensure that your electric tool can get the power that it needs to function without an accident. 3. Use the right tool correctly. Use tools correctly and for their intended purposes. Follow the safety directions and operating procedures recommended by the manufacturer. When working on a circuit, use approved tools with insulated handles. 4. Protect your Tools. Keep tools and cords away from heat, oil, and sharp objects. These hazards can damage insulation. If a tool or cord heats up, stop using it. Report the condition to a supervisor or instructor immediately. 5. Use double-insulated tools - Portable electrical tools are classified by the number of insulation barriers between the electrical conductors in the tool and the worker. 6. Storing Your Tools- Keep your electric tools stored in their original cases and containers. This will keep them free of dust and dirt while they are not being used. 7 What’s More Let us try another activity if you gained already a deeper knowledge about our lesson.
