ACTIVITY 1

Mang Ramon worked as a computer technician in a big company. One
day, his son, Badong, has been curious about the different hand tools used in
troubleshooting and maintaining a computer. He wanted to assist his father while
fixing a computer, but he had a hard time getting the right tool that his father
needed to complete his job. Let us help Badong to identify the tools!

PROPER TOOL SELECTION

A hand tool is a handheld device that aids in accomplishing a task. It is
important to know the proper usage of every hand tool in preparing tasks.

To accomplish a hardware repairs, it is important to have necessary tools
to be used in maintaining and troubleshooting a computer.

6

CATEGORIES OF HARDWARE TOOLS AND ITS USES

Electro-Static Discharge (ESD) Tools
Static electricity is easily generated by friction on carpets, tile flooring, clothing, hair,
fabric, 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 antistatic work mats used with antistatic wrist straps provide the most basic
means for the controlled discharge of electrostatic electricity. Examples of ESD Tools:

Anti-static wrist strap – protects computer
equipment when grounded to a computer chassis.

Anti-static mat – used to stand on or place
hardware on to prevent static electricity from
building up.

Hand Tools
Tools that are used mainly by our two hands to operate.

Torx screwdriver - used to loosen or tighten
screws that have a star-like depression on the
top, a feature that is mainly found on laptop.

Needle-nose plier – it is commonly used to
cut and bend small wires and electrical wiring.

Wire cutter – commonly used to cut copper,
brass, iron, aluminum, and steel wire.

Philips head screwdriver – used to loosen
or tighten X-slotted screws.

7

Tweezers – usually used to hold and
manipulate small parts.

Flat head screwdriver – usually used to
tighten or loosen screws that have a straight,
linear notch in their heads.

Part retriever – it is commonly used to
retrieve parts from the location that are small
for your hand to fit or jammed bits in the
motherboard.

Flashlight – it is used to provide light in areas
that you cannot see well.

Hex driver - commonly used to loosen and
tighten bolts that have a hexagonal(six-sided)
head.

Crimping tool - is a device used to conjoin
two pieces of metal by deforming one or both
to hold each other.

Punched-down tool - it is used to terminate wire
into termination blocks. Some cable connectors
must be connected to cables using a punch down
tool.

Wire Stripper - a small hand-held device that
usually used to strips the electrical insulation
from electric wires.

8

Soldering iron – it is used to join two or more
items together by melting and putting a filler metal
(solder) into the joint.

Solder stand – it is used to hold the soldering iron.

Solder - it is used for connecting an electrically
conductive element

Desoldering tool- it is used to remove excess
solder in a printed circuit.

Cleaning Tools
It is important to have an appropriate cleaning tools when repairing or maintaining
computers. Using these tools will keep computers away from damaging or having scratches.

Lint-free cloth – used to clean different
computer components without scratching or
leaving debris.
Compressed air – used to blow away dust
and debris from different computer parts
without touching the components.

Cable ties – usually used in holding the
items together, mostly used in electrical
cables and wires.

Parts organizer – it is used to storing screw,
jumpers, fasteners, and other small
component and avoid the small pieces to
mixed.

9

Diagnostic Tools
Diagnostic tools can be used to scan your computer’s hard drive, check your ram for errors,
check microprocessor temperature and give you information about any other devices
connected to your computer.

Multimeter is a handy tool that you use to
measures AC/DC voltage, electric current,
and other cable and electrical characteristics.

Loopback Adapter - it is used as a testing
tool for a virtual network environment where
network access is not available.

LAN tester - it is used to check most network
cable wiring.

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

The person should be trained on safety procedures in
working with tools. Do not forget that safe practices when carrying
or storing those tools should be incorporated while working. Tools
can pose a safety risk when they are misplaced or improperly
handled.

Common Hand Tool Inspection Items

Screwdrivers. Ensure the handle is not chipped or broken. Many people will use the screwdriver
as a chisel and hit the back end of it with a hammer. This causes damage to the screwdriver
and will damage the handle. If the head of the screwdriver is chipped or worn down, replace the
screwdriver.

10

Multimeter. You can detect certain faults by looking at the needle of an analog meter. It should
be on 0 and respond to the adjustment screw and should be centered with respect to the dial.
The front spring if visible should unbroken and appear to be in good condition. The needle should
also not move much if the meter is moved gently from side to side and should return to 0 when
you stop moving it.
LAN Tester. It is defective and if the lights are not turning on if you replace the battery with a new
one, still the problem persists.
Soldering Iron. It run on electricity and, if the circuit is broken, the electricity will no longer work.
If your soldering iron is not producing any heat, it is likely because of a break in the electrical
circuit, resulting from either a faulty connection in the iron or heating element failure.
Punched Down Tool. If the tool cannot cut through the cable, then the cutting edge mut be dull
and need replacement.

To avoid injuries, remember the following safety procedures:
1. Use the right tool for the job.
✓ Do not use your wrench as a hammer.
✓ Do not use a screwdriver as a chisel, etc.
2. Do not use broken or damaged tools, dull cutting tools or screwdrivers with
worn tips.
3. Cut in a direction away from your body.
4. Make sure your grip and footing are secure when using tools.
5. Carry tools securely and safely.
6. Pass a tool to another person by the handle; never toss it to them.
7. Use the right personal protective equipment, or PPE, for the job.
8. Never carry sharp or pointed tools, such as a screwdriver, in your pocket.
9. Always keep your tools in good condition and store it properly.

Following these precautions can prevent injuries and provide a safer
workplace!
