Answer:
5S - Sort, Systematize, Sweep, Sanitize, and Self-Discipline
Functional tools and equipment - those that are in good condition and can perform its regular functions
Lubricant - a substance introduced to lessen friction between moving surfaces; also functions to transport external particle
Lubrication additives- many of the physical properties of various oils and greases
Non-functional tools and equipment - those that are not able to perform its regular function because of impaired and damage part
Nonpolar solvents - solvents which do not dissolve/are insoluble in water Pneumatic tool - instrument activated by air pressure
Polar solvents - solvents which dissolve/are soluble in water
Solvent - a component of a solution that dissolves solute and is usually present in large proportion or amount
Sorting - to sort everything in a work area

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.
1. Hammers are mostly used tools in the shop. They should be gripped at the end of the handle.
2. Pliers are specified types of adjustable wrenches. The two legs move on a pivot so that items of various sizes can be gripped.
3. 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.
4. 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. tools
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
