What Do You Already Know?

Let us determine how much you already know about checking conditions of tools and equipment. Take this test.

What Do You Need To Know?

Read the Information Sheet 1.1 very well then find out how much you can remember and how much you learned by doing Self-check 1.1.

Information Sheet 1.1

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 hands equipment includes any machine powered by electricity.

1. Hand tools are tools manipulated by hands without using electrical energy such as: puller, hacksaw, pull-push rule, pliers, hammer, and others.

2. Machine/Power tools are tools manipulated by our hands and with the use of electrical energy such as: electric drill, grinding wheels, vacuum cleaner and others.

3. Pneumatic tools are tools or instruments activated by air pressure. Pneumatic tools are designed around three basic devices: the air cylinder, the vane motor, and the sprayer

A. Hand tools

They include screwdrivers, hammers, pliers, wrenches and pullers.

1. Screwdrivers are used to drive, or turn screws. The common type has a single flat blade for driving screws with slotted heads. The other type has the cross slotted head.

2. Hammers are mostly used tools in the shop. They should be gripped at the end of the handle.

3. Pliers are specified types of adjustable wrenches. The two legs move on a pivot so that items of various sizes can be gripped.

4. Wrenches are used to turn screws, nuts and bolts with hexagonal heads. ―Hexagonal‖ means six-sided. A variety of wrenches are used in the shop.

5. Pullers are used to remove gears and hubs from shafts, bushings from blind holes, and cylinders’ liners from the engine blocks.

B. Machine/Power Tools

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.

3. Vacuum cleaner is used for cleaning the floor and car interiors after service.

C. Pneumatic tools

1. Pneumatic Torque Wrench. This wrench uses compressed air to quickly and powerfully turn nuts, bolts, and other objects.

2. Air chisel uses reciprocating motion to drive a cutting hammering tool. An air hammer drives a chisel to cut off a nut that has frozen to a stud. It can be used with a variety of tools-cutters and punches to do many jobs.

3. Air drill is lighter than a comparable electric drill. Repeatedly stalling or overloading does not damage or overheat the air drill.

4. Air racket uses the sockets and attachments from a standard socket set.

5. Pneumatic floor jack uses compressed air to flow into the jack cylinder and causes the ram to extend and raise the vehicle.

Operation Sheet 1.1

A. 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.

B. Personal Protective Equipment (PPE)

Personal Protective Equipment (PPE) are gadgets to protect workers from injury or illness caused by having contact with the dangers/hazards in the workplace whether they are chemical, biological, radiation, physical, electrical, mechanical and others.

These are the common Personal Protective Equipment gadgets:

*Hard Hats/ Helmets

*Gloves

*Goggle

*Mask

*Work boots Pants

REMEMBER

1. Personal protective equipment should be taken cared as of the other tools and equipment. Wipe your helmets, gloves, safety shoes before keeping it.

2. It should also be cleaned, kept in proper tool rack/ cabinet.

3. It should be stored in dry places so that it will not have mold build-up.

4. Over-all suites should be washed regularly so that perspirations and other dirt will be washed clean.

C. 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 in your shop.

B. Classify your tools according to is function.

Method 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 occurs 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.

Classifications of tools and equipment according to their uses:

1. Measuring tools

2. Holding tools

3. Cutting tools

4. Driving tools

5. Boring tools 6. Electrical equipment

7. Miscellaneous tools/instrument/equipment

Non-functional tools and equipment are those that are not able to perform its regular function because of impaired and damage part. Examples of these are the following:
