4. Prepare Hand Tools
Preparing for the task to be undertaken
includes proper tool selection.
1. 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.

5. 2. 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.

6. 3. When obtaining the tool all the
associated tooling and 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.

7. HARDWARE TOOLS

8. HARDWARE TOOLS
Hardware tools are grouped into four
categories:
Electrostatic Discharge (ESD) tools
Hand tools
Cleaning tools
Diagnostic tools

9. Electrostatic Discharge (ESD)
Tools
Grounded antistatic work
mats used with antistatic
wrist straps provide the
most basic means for the
controlled discharge of
electrostatic electricity.

10. Anti-static wrist strap –
used to prevent ESD
damage to computer
equipment
Anti-static mat – used to
stand on or place
hardware on to prevent
static electricity from
building up

11. Hand Tools
A hand tool is a device
for performing work on
a material or a physical
system using only
hands.

12. Flat head screwdriver –
used to loosen or tighten
slotted screws.
Philips head screwdriver –
used to loosen or tighten
crosshead screws
Torx screwdriver - used to
loosen or tighten screws
that have a star-like
depression on the top

13. Hex driver – sometimes
called a nut driver, is used
to tighten nuts in the same
way that a screwdriver
tightens screws.
Needle-nose plier –
used to hold small
parts
Wire cutter – used to
strip and cut wires.

14. Tweezers – used to
manipulate small parts.
Part retriever – used to
retrieve parts from location
that are to small for your
hand to fit.
Flashlight – used to light up
areas that you cannot see
well.
Pliers are used for holding,
turning and cutting tasks

15. Cleaning Tools
Using these tools ensures that computer
components are not damaged during cleaning.
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

16. Cable ties – used to
bundle cables neatly
inside and outside of
a computer.
Parts organizer – used
to hold
screw, jumpers,
fasteners and other
small parts and
prevents them from
getting mixed
together.

17. Diagnostic Tools
.
Multimeter – used to test
the integrity of circuits
and the quality of
electricity in computer
components.
Loopback Adapter –
used to test the
functionality of computer
ports.
