2. Learning Outcome
• Select a best tool on a certain job.
• Learn environmental Safety and Health
program requirements.
• Discover the different types of tools and
learn there functions.

3. Learning Content
• Proper Tool Selection.
• Preparing for the task.
• Safe use of Tools
• Different Types of Tools and their
examples.

4. PROPER TOOL SELECTION
• A tool is a handheld device that aids in
accomplishing a task. Tools range from a
traditional metal cutting part of a machine
to an element of a computer program that
activates and controls a particular function.

5. Preparing for the task
• How do you select the best tool for the
job? First, know and understand in detail
the scope of work to be accomplished,
second, plan for the scope taking into
account the sequence of tasks.

6. Preparing for the task
• Selecting the best tool for each task
requires training in the proper use of the
tools, field experience in their safe use,
and following the manufacturer’s guidance
and instructions for that specific tool.

7. Preparing for the task
• When obtaining the tool all the associated
tooling and consumable parts, as
recommended by the manufacturer, must
be included. In addition, related
consumable parts must also be selected
and used according to their manufacturer’s
instructions.

8. Safe use of Tools
• Once selected, use the tool for the
purpose for which it was designed. Not all
tools come with detailed instructions, but
there are those that do spell out the safety
- Do’s and Don’ts for the your safety. If
there are set-up or use options, operator
judgment must always be based on what
is the safest way to use the tool.

9. Safe use of Tools
Environmental Safety and Health Program
requires the following:
• All tools be kept in good condition with regular
maintenance
• The right tool must be used for the job
• Each tool be examined before use AND
• damaged or defective tools NOT to be used
• Tools be operated according to manufacturer’s
instructions
• The right protective equipment for the tool and activity be
used

10. To complete hardware repairs, it is important to
have a toolkit that should contain all of the
necessary tools. As you gain experience, you will
learn which tools to have available for different
types of jobs. Hardware tools are grouped into
these four categories.
Electro-Static Discharge (ESD) tools
Hand tools
Cleaning tools
Diagnostic tools

11. Electro-Static Discharge (ESD) Tools
• Static electricity is easily generated by friction
on carpets, tile flooring, clothing, hair, fabric, and
etc. The friction of moving air alone will charge
suspended particles and cause the buildup of
static electrical charges on people and objects in
the environment. Grounded anti-static work
mats used with anti-static wrist straps provide
the most basic means for the controlled
discharge of electro-static electricity.

12. Electro-Static Discharge (ESD) Tools
ESD TOOLS MEANING
Prevents the sudden flow of electricity to avoid damage
Your computer components and parts.

13. Electro-Static Discharge (ESD) Tools
Anti-static wrist strap
used to prevent ESD damage to computer equipment.

14. Electro-Static Discharge (ESD) Tools
Anti-static Mat
used to stand on or place hardware on to prevent static
electricity from building up.

15. Electro-Static Discharge (ESD) Tools
Anti-static Jacket
used to avoid contact in our body and other objects.

16. Electro-Static Discharge (ESD) Tools
Anti-static Slipper
used prevent ESD and protection from electrical shocks.

17. HAND TOOLS
A hand tool is a device for performing work on a
material or a physical system using only hands. The
hand tools can be manually used employing force, or
electrically powered, using electrical current.

18. HAND TOOLS
Flat Head Screwdriver
used to loosen or tighten slotted ( - )screws.

19. HAND TOOLS
Philips Head Screwdriver
used to loosen or tighten crosshead (+) screws.

20. HAND TOOLS
Torx Screwdriver
used to loosen or tighten screws that have a star-like head.

21. HAND TOOLS
Hex Driver
sometimes called a nut driver, is used to tighten nuts in the same
way that a screwdriver tightens screws.

22. HAND TOOLS
Needle-Nose Plier
Used to hold small parts and bend wire.

23. HAND TOOLS
Wire Cutter
used to strip and cut wires.

24. HAND TOOLS
Tweezers
used to manipulate small parts.

25. HAND TOOLS
Parts Retriever
used to retrieve parts from location
that are to small for your hand to fit.

26. HAND TOOLS
Flashlight
used to light up areas that you
cannot see well.

27. CLEANING TOOLS
Having the appropriate cleaning tools is essential when
maintaining or repairing computers.
Using these tools ensures that computer components are
not damaged during cleaning.

28. CLEANING TOOLS
Lint-Free Cloth
used to clean different computer components
without scratching or leaving debris.

29. CLEANING TOOLS
Compressed Air
used to blow away dust and debris from different computer
parts without touching the components.

30. CLEANING TOOLS
Cable Ties
used to bundle cables neatly
inside and outside of a computer.

31. CLEANING TOOLS
Parts Organizer
used to hold screw, jumpers, fasteners and other small parts
and prevents them from getting mixed together.

32. DIAGNOSTIC TOOLS
Computers are easier to use and more dependable with
each new generation of hardware and operating system
update, but that doesn't mean they're problem-free.
So we have these tools to check and test every
components and port of the computer system.

33. DIAGNOSTIC TOOLS
Multimeter
used to test the integrity of circuits and the quality
of electricity in computer components.

34. DIAGNOSTIC TOOLS
Loopback Adapter
used to test the functionality of computer ports.

35. DIAGNOSTIC TOOLS
Network Tester
used to test the performance of your network cables.
