This document discusses proper electrical tool storage, classification, and maintenance. Tools should be stored in dry, accessible locations and clearly labeled. Commonly used tools are stored at center shelves while heavy tools are lowest. Tools must be cleaned after use, stored properly, and maintained to prevent rust and ensure sharpness. Regular maintenance of power tools helps ensure optimal efficiency, safety, and productivity. Lubricants are also important to apply to reduce friction and prevent wear during use.

1. ELECTRICAL INSTALLATION AND
MAINTENANCE

2. PROPER TOOL STORAGE

3. TOOL STORAGE
Proper storage of tools ensures
their durability and efficiency. They
must be stored in dry places. Correct
labeling of cabinets and tool racks in
accessible locations for laboratory
activity in the shop is also important.

4. CLASSIFICATION OF TOOLS
• Cutting tools
• Driving tools
• Drilling Equipment
• Soldering equipment
• Measuring tools
• Hydraulics
• Portable tools/ Equipment
• Bending Tools

5. BASIC TIPS IN STORING ELECTRICAL
TOOLS AND EQUIPMENT
 Commonly used tools and equipment should be
placed at the center shelves of the cabinet.
 Heavy tools and equipment like power grinder
should be placed at the lowest shelf.
 Light tools should be placed at the upper shelf.
 Tools and equipment must be stored according to
their kinds.
 Defective tools shall be kept in section intended for
them for inventory purposes.

6. HOW TO HANDLE AND MAINTAIN
TOOLS
1. Wipe or clean tools after every use with a clean and soft cloth
to remove dirt.
2. Keep all tools in the tool room and tool rack.
3. Tools should be applied/wiped with an appropriate oil to
prevent them from rusting.
4. Drill tools should be sharpened properly.
5. Tooth cutting tools should be sharpened as often as necessary.
6. Never drop tools especially precision instrument or testing
tools.
7. Except for hammers, never use other tools as hammers.

7. HOW TO HANDLE AND MAINTAIN
TOOLS
8. Never use screwdrivers as wood chisel or cold chisel.
9. Never file the soldering tip of the soldering copper. If necessary,
wipe the tip with a clean soft cloth to remove dirt.
10. Do not overheat the electric soldering copper.
11. Never use drill tools. They will cause harm to your work or even
to yourself.
12. Always issue or lend tools with a receipt.
13. Tools borrowed should be returned in a good condition;
otherwise it should be replaced with a new and similar kind.

8. MAINTENANCE PROCEDURE
Maintenance is an action carried out to
retain an item in or to restore it to an
acceptable condition.
Regular maintenance and servicing of
power tools and electric tools will help to
ensure that they operate with the optimum
efficiency at all times. This will not only help to
keep tool operating costs low but it can also
increase tool safety and productivity.

9. MAINTENANCE PROCEDURE
The first thing to do in any
preventive maintenance system is to use
your power of observation. The most
important items of "equipment" for
implementing an effective preventive
maintenance system are our eyes, nose,
ears, experience, and judgment.

10. PLANNED MAINTENANCE
1. Preventive maintenance is performed in order to
prevent failures before they develop into a
breakdown.
2. Corrective maintenance is performed in order to
correct a failure.
3. Emergency maintenance is necessary to put the
item at hold immediately to avoid serious
consequences such as the loss of production,
extensive damage of assets, and for safety
reasons.

11. LUBRICANT
A substance that helps to reduce
friction between surfaces in mutual
contact, which ultimately reduces
heat generated when the surfaces
move.

12. TYPES OF LUBRICANT
1. Liquid
2. Solid
3. Grease
4. Paste
 Liquid lubricant. A lanolin or natural water repellent
lanolin is derived from wool grease and a safe alternative
of those common petro chemical based lubricants. These
lubricants are also preventive agents against corrosion.
 Water. It can also be used as a major component aside
from other based oils.
 Vegetable oils. These are primarily derived from plants
and animals.

13. PURPOSE OF LUBRICATING
 Keeps moving part apart
 Reduces friction
 Transfers heat
 Carries away contaminant and debris
 Transmits power
 Protects against wear
 Prevents corrosion
