LEARNING OBJECTIVES:
After reading this INFORMATION SHEET, YOU MUST be able to:
1. Identify hand tools and its operations and functions.
2. Identify four types of Hardware tools
Hardware Tools

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 tool

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 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 – used to prevent ESD damage to computer

equipment.

Safe Use of Tools

Once selected, use the tool for the purpose for which
it wasdesigned. Not all tools come with detailed instructions,
but 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.

Environmental Safety and Health Program requires

the following:

 All tools be kept in good condition with regular

maintenance.
 Theright tool 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.
 Theright protective equipment for the tool and activity
beused.

What are the basic tips when using hand tools?

 Ensure that employees are properly trained in the safe use of hand
tools.
 Always provide training on how to choose the right tool for the job, how
to correctly use each tool, and how to identify when tools need repair.
 Select the right tool for the job. Substitutes increase the chance of
having an accident.
 Use tools designed to allow wrist to stay straight. Avoid using hand
tools with your wrist bent.
 Use good quality tools.

The purpose of an antistatic wrist strap is to equalize the electrical charge between you
and the equipment. The antistatic wrist strap is a conductor that connects your body to
the equipment that you are working on. When static electricity builds up in your body,
the connection made by the wrist strap to the equipment, or ground, channels the
electricity through the wire that connects the strap.

The wrist strap has two parts and is easy to wear:

• Wrap the strap around your wrist and secure it using the snap or
Velcro. The metal on the back of the wrist strap must remain in contact with
your skin at all times.

 Snaptheconnector at the end of the wire to the

wrist strap, and connect the other end either to the equipment or to
the same grounding point that the antistatic mat is connected to. The metal
skeleton of the case is a good place to connect the wire. When connecting
the wire to equipment that you are working on, choose an unpainted metal
surface. A painted surface does not conduct the electricity as well as
unpainted metal.

An antistatic mat is slightly conductive. It works by drawing static electricity away from a
component and transferring it safely from equipment to a grounding point:

• Lay the mat on the workspace next to or under the computer case.

• Clip the mat to the case to provide a grounded surface on which

you can place parts as you remove them from the system. Reducing the potential
for ESD reduces the likelihood of damage to delicate circuits or
components.

Proper Use of Hand Tools

A technician needs to be able to properly use each tool in the toolkit. This topic covers
many of the various hand tools used when repairing computers.

Screws

Match each screw with the proper screwdriver. Place the tip of the screwdriver on
the head of the screw. Turn the screwdriver clockwise to tighten the screw and
counterclockwise to loosen the screw. Screws can become stripped if you over-tighten
them with a screwdriver. A stripped screw, may get stuck in the screw hole, or it may
not tighten firmly. Discard stripped screws.

Flat head screwdriver

Use a flat head screwdriver when you are working with a slotted screw. Do not use a flat
head screwdriver to remove a Phillips head screw. Never use a screwdriver as a pry
bar. If you cannot remove a component, check to see if there is a clip or latch that is
securing the component in place.

Caution: If excessive force is needed to remove or add a component, something is

probably wrong. Take a second look to make sure that you have not missed a screw or
a locking clip that is holding the component in place. Refer to the device manual or
diagram for additional information.

Phillips head screwdriver

Use a Phillips head screwdriver with crosshead screws. Do not use this type of
screwdriver to puncture anything. This will damage the head of the screwdriver.

Hex driver

Use a hex driver to loosen and tighten bolts that have a hexagonal (six-sided) head.
Hex bolts should not be over-tightened because the threads of the bolts can be
stripped. Do not use a hex driver that is too large for the bolt that you are using.

Caution: Some tools are magnetized. When working aroundelectronic devices, be sure
that the tools you are using have not been magnetized. Magnetic fields can be harmful
to data stored on magnetic media. Test your tool by touching the tool with a screw. If the
screw is attracted to the tool, do not use the tool.

Part retriever, Needle-nose pliers, or tweezers

The part retriever, needle-nose pliers, and tweezers can be used to place and retrieve
parts that may be hard to reach with your fingers. Do not scratch or hit any components
when using these tools. Caution: Pencils should not
be used inside the computer to change the setting of switches or to pry off jumpers. The
pencil lead can act as a conductor and may damage the computer components.

Computer Cases and Monitors

Clean computer cases and the outside of monitors with a mild cleaning solution on a
damp, lint-free cloth. Mix one drop of dishwashing liquid with four ounces of water to

create the cleaning solution. If any water drips inside the case, allow enough time for
the liquid to dry before powering on the computer.

LCD Screens

Do not use ammoniated glass cleaners or any other solution on an LCD screen, unless
the cleaner is specifically designed for the purpose. Harsh chemicals will damage the
coating on the screen. There is no glass protecting these screens, so be gentle when
cleaning them and do not press firmly on the screen.

CRT Screens

To clean the screens of CRT monitors, dampen a soft, clean, lint-free cloth with distilled
water and wipe the screen from top to bottom. Then use a soft, dry cloth to wipe the
screen and remove any streaking after you have cleaned the monitor. Clean dusty
components with a can of compressed air. Compressed air does not cause electrostatic
buildup on components. Make sure that you are in a well-ventilated area before blowing
the dust out of the computer. A best practice is to wear a dust mask to make sure that
you do not breathe in the dust particles. Blow out the dust using short bursts from the
can. Never tip the can or use the compressed air can upside down. Do not allow
the fan lades to spin from the force of the compressed air.
Hold the fan in place. Fan motors can be ruined from spinning when the motor is not
turned on.

Component Contacts

Clean the contacts on components with isopropyl alcohol. Do not use rubbing
alcohol. Rubbing alcohol contains impurities that can damage contacts. Make sure that
the contacts do not collect any lint from the cloth or cotton swab. Blow any lint off the
contacts with compressed air before reinstallation.

Keyboard

Clean a desktop keyboard with compressed air or a small, handheld vacuum cleaner
with a brush attachment. Caution: Never use a standard vacuum cleaner inside a
computer case. The plastic parts of the vacuum cleaner can build up static electricity
and discharge to the components. Use only a vacuum approved for electronic
components.

Mouse
Use glass cleaner and a soft cloth to clean the outside of the mouse. Do not spray
glass cleaner directly on the mouse. If cleaning a ball mouse, you can remove the ball
and clean it with glass cleaner and a soft cloth. Wipe the rollers clean inside the mouse
with the same cloth. Do not spray any
liquids inside the mouse.

Personal Protective Equipment (PPE)

Personal protective equipment will be provided without cost to all individuals who are
at risk of occupational exposure to bloodborne pathogens. Personal protective
equipment will be chosen based on the anticipated exposure to blood or
other potentially infectious materials. The protective equipment will be considered
appropriate only if it does not permit blood or other potentially infectious materials to
pass through or reach the individual’s clothing, skin, eyes, mouth, or other mucous
membranes under normal conditions of use and for the duration of time which the
protective equipment will be used.

Eye Protection
Protective eye wear must be worn in the laboratory at all times.
Face shields may be required if there is a potential for splashes, sprays, or aerosols.

Lab coats and uniforms

Laboratory coats, gowns, smocks, or uniforms must be worn while in the laboratory;
long sleeves are required. Before leaving the laboratory for non-laboratory areas (e.g.,
cafeteria, library, administrative offices), this protective clothing must be removed and
left in the laboratory. Sandals and open-toed shoes are not permitted.

Using tools properly helps prevent accidents and damage to equipment and people.
This section describes and covers the proper use of a variety of hardware, software,
and organizational tools specific to working with computers and peripherals.

Proper Use of ESD Tools

Proper Use of ESD Tools

The purpose of an antistatic wrist strap is to equalize the electrical charge between you
and the equipment. The antistatic wrist strap is a conductor that connects your body to
the equipment that you are working on.

and basic calculation
When static electricity builds up in your body, the connection made by the wrist strap to
the equipment, or ground, channels the electricity through the wire that connects the
strap.

The wrist strap has two parts and is easy to wear:

1. Wrap the strap around your wrist and secure it using the snap or Velcro.
The metal on the back of the wrist strap must remain in contact with your
skin at all times.

2. Snap the connector at the end of the wire to the wrist strap, and connect
the other end either to the equipment or to the same grounding point that
the antistatic mat is connected to. The metal skeleton of the case is a
good place to connect the wire.

When connecting the wire to equipment that you are working on, choose an unpainted
metal surface. A painted surface does not conduct the electricity as well as unpainted
metal.

An antistatic mat is slightly conductive. It works by drawing static electricity away from a
component and transferring it safely from equipment to a grounding point:

1. Lay the mat on the workspace next to or under the computer case.
2. Clip the mat to the case to provide a grounded surface on which you can
place parts as you remove them from the system. Reducing the potential
for ESD reduces the likelihood of damage to delicate circuits or
components.

screwdriver on the head of the screw.
 Turn the screwdriver clockwise to tighten the screw and counter-
clockwise to loosen the screw.

 Screws can become STRIPPED if you over-tighten them with a

screwdriver. A stripped screw, may get stuck in the screw hole, or it may
not tighten firmly. Discard stripped screws.

Flat head screwdriver

 Use a flat head screwdriver when you are working with a slotted screw.

 Do not use a flat head screwdriver to remove a Phillips head screw.

CAUTION: Some tools are magnetized. When working around electronic devices, be
sure that the tools you are using have not been magnetized. Magnetic fields can be
harmful to data stored on magnetic media. Test your tool by touching the tool with a
screw. If the screw is attracted to the tool, do not use the tool.

Part retriever, Needle-nose pliers, or tweezers

 The part retriever, needle-nose pliers, and tweezers can be used to place and
retrieve parts that may be hard to reach with your fingers. Do not scratch or hit
any components when using these tools.

CAUTION: Pencils should not be used inside the computer to change the setting of
switches or to pry off jumpers. The pencil lead can act as a conductor and may damage
the computer components.

 Keeping computers clean inside and out is a vital part of a maintenance program.
Dirt can cause problems with the physical operation of fans, buttons, and other
mechanical components. On electrical components, an excessive build-up of
dust will act like an insulator and trap the heat. This insulation will impair the
ability of heat sinks and cooling fans to keep components cool, causing chips and
circuits to overheat and fail.

CAUTION: When compressed air is used to clean inside the computer, the air should
be blown around the components with a minimum distance of four inches from the
nozzle. The power supply and the fan should be cleaned from the back of the case.

CAUTION: Before cleaning any device, turn it off and unplug the device from the power
source.

Computer Cases and Monitors

Clean computer cases and the outside of monitors with a mild cleaning solution on a
damp, lint-free cloth. Mix one drop of dishwashing liquid with four ounces of water to
create the cleaning solution. If any water drips inside the case, allow enough time for
the liquid to dry before powering on the computer.

LCD Screens

Do not use ammoniated glass cleaners or any other solution on an LCD screen, unless
the cleaner is specifically designed for the purpose. Harsh chemicals will damage the
coating on the screen. There is no glass protecting these screens, so be gentle when
cleaning them and do not press firmly on the screen.

  To clean the screens of CRT monitors, dampen a soft, clean, lint-free cloth with
distilled water and wipe the screen from top to bottom. Then use a soft, dry cloth
to wipe the screen and remove any streaking after you have cleaned the monitor.
Clean dusty components with a can of compressed air.

 Compressed air does not cause electrostatic buildup on components. Make sure
that you are in a well-ventilated area before blowing the dust out of the computer.
A best practice is to wear a dust mask to make sure that you do not breathe in
the dust particles.

 Blow out the dust using short bursts from the can. Never tip the can or use the
compressed air can upside down. Do not allow the fan blades to spin from the
force of the compressed air. Hold the fan in place. Fan motors can be ruined
from spinning when the motor is not turned on.

Proper Use of Cleaning Materials

 Component Contacts

Clean the contacts on components with

isopropyl alcohol. Do not use rubbing alcohol. Rubbing
alcohol contains impurities that can damage contacts.
Make sure that the contacts do not collect any lint from
the cloth or cotton swab. Blow any lint off the contacts
with compressed air before reinstallation.

Keyboard

Clean a desktop keyboard with compressed air or a small,

hand-held vacuum cleaner with a brush attachment.

MAINTENANCE OF TOOLS

LEARNING OBJECTIVES:
After reading this INFORMATION SHEET, YOU MUST be able to:

1. Know the importance in maintaining tools and equipment

2. Perform the proper way of maintaining tools and equipment

MAINTAIN HAND TOOLS

All tools and equipment must be properly maintained so that workers are
not endangered. Regulations require inspections of tools, machines
and equipment before use.
Preventive maintenance is the systematic care and protection of tools,
equipment and machines in order to keep them in a safe, usable condition
limit downtime and extend productivity. We must always be aware that
maintenance tasks themselves are potentially hazardous and can result in
injury. The successful maintenance program is:
• Well organized and scheduled,
• Controlshazards,
• Definesoperationalprocedures,and
• Trains keypersonnel

The degree of detail to include regarding tools and equipment maintenance

will depend on the kinds of tools/equipment used. Some construction
equipment may have very specific inspection and maintenance
requirements. Electronic equipment may have different maintenance
requirements. Hand tools may require only basic maintenance. Power tools
should be maintained in good working order. This may be limited to ensuring
that blades/bits are replaced when needed and those guards or other safety

devices are operable and any damaged electrical cords/plugs are repaired or
replaced. Damaged or defective equipment/tools should be tagged and
removed from service.

General requirements for tools and equipment maintenance include:

 Obtaining a copy of the maintenance schedule recommended by the
manufacturer
 Ensuring that maintenance is performed as required
 Ensuring that the person(s) performing the maintenance are
competent (e.g. licensed
 mechanic) Retaining records of maintenance/service conducted
 Specifying who is responsible for overseeing equipment maintenance
and where the records are kept Set up a system for removal and
tagging of damaged or defective tools andequipment

Make it a habit to clean tools after each use before you return them to
storage. Wipe them down with a rag or old towel and be sure they are free of
dust, grease and debris before you put them into their proper places. This is
also an opportunity to look for any damage or defects. Check your tools'
handles for splinters, breaks and cracks. Also, make sure that metal parts
show no signs of corrosion or rust. Repair or replace any tools that show
signs of damage.

Cold chisels, log-splitting wedges and other striking tools can be very
dangerous if they are not maintained properly. Because these types of tools

are used for repeated striking, the surface of the metal head eventually
mushrooms out and spreads to form a lip or ridge around the edge. With
continued use, there is more spreading and the metal lip may continue to
thin, split or curl until it finally breaks. If the metal head separates from the
handle while in use, this could result in a dangerous projectile. To prevent
this hazard, just grind off the metal edges with a powered grinder on a
regular basis.

Safety Alerts!

Don’t use tools that need repair or replacement. Broken tools can cause
injury.

Don’t use tools inappropriately; you risk injury to yourself, others and
damage to the tools.

Safety Alert!

You should wear heavy gloves when cleaning or removing rust from
tools that can cut. Wear safety goggles when using a wire brush to
remove rust.

Tool and Equipment Maintenance

The degree of detail to include regarding tools and equipment maintenance

will depend on the kinds of tools/equipment used. Some construction
equipment may have very specific inspection and maintenance
requirements. Electronic equipment may have different maintenance
requirements. Hand tools may require only basic maintenance.
Power tools should be maintained in good working
order. This may be limited to ensuring that blades/ bits are replaced when
needed and those guards or other safety devices are operable and any
damaged electrical cords/plugs are repaired or replaced.
Damaged or defective equipment/tools should be tagged and
removed from service. Most manufacturers can provide maintenance
schedules for their equipment. Large companies typically have a
comprehensive maintenance program due to the capital investment and/or
leasing agreements. Smaller companies may lease equipment and
maintenance services may be included in the leasing agreement. General
requirements for tools and equipment maintenance include:
