Lesson
1
Using and Maintaining Hand
Tools
Using and maintaining hand tools help you acquire the knowledge, skills and
attitudes you needed in identifying, preparing, using and maintaining tools and
equipment in Computer System Servicing as your basic step in becoming a proficient
computer technician.
What’s In
Do you have hand tools at home? Can you identify them? Some of these tools are
used in repairing and maintaining electrical and electronics at home.
In this module, you will always learn different hand tools and its uses in repairing
and maintain computer devices to avoid damage of tools and safety procedures in
using tools with appropriate Personal Protective Equipment PPE.
Notes to the Teacher
1. Read the lessons properly. These will guide you
to do at
end of this module.
2. Find out what you already know by taking the
learningthe activities.
3. Apply what you have learned in another activity
or real- life situation.
8
What’s New
Activity 1:
Andrew loves to help his father, Manong Tony, a technician, in their computer shop.
To assist his father, he needs to identify properly the tools in the shop. Let us help
identify these tools!
9
Proper Tools and Selection
In repairing and maintaining hardware equipment, it is necessary to have a toolkit
that should contain all the necessary tools in different types of job. Now, you will
learn which tools to use in preparing a task.
Common the name of tools and its uses
Table 1. Tools and its uses
Tools
Picture
1. Long Nose Pliers Usually for holding, bending and
stretching the lead of electronics component or
connecting wire.
2. Wire Cutter Used for Cutting copper, brass, iron,
aluminum and steel wires.
3. Flat Head Screwdriver Usually drive or fasten
negative slotted screws.
4. Philips Head Screwdriver won’t to drive or fasten
positive slotted screws
5. Soldering iron is a hand tool won’t to join two or
more metal conductors with the support of
soldering lead melted around it.
6. Soldering Stand This can be an easy hand tool
stand composed of a heavy-duty metal base and
a reinforced spring holder.
7. Soldering Lead could be an alloy accustomed to join
together metal workpieces.
10
8. Soldering Flux allows you to supply a clean
soldered.
9. Crimping Tool may be a device won’t to conjoin
two pieces of metal by deforming one or both
during a way that causes them to carry one other.
10. Wire Stripper may be a small, hand-held device
that usually strips the electrical insulation from
electric wires.
11. Tweezer is a tool won’t to manipulate small
parts.
12. Anti-static wrist strap usually safely ground an
individual functioning on very sensitive electronic
equipment, to forestall the buildup of electricity
on their body, which might lead to electrostatic
discharge (ESD) Equipment.
13. Multi-tester Usually tests the integrity of circuits
and therefore the quality of electricity in computer
components.
14. Lan Tester designed to check most network cable
wiring.
11
Proper use of hand tools
A computer technician is requiring using appropriate tools within the toolkit when
repairing computers. Here is the correct use of tools in working areas.
Several tools are attracted. When working around electronic devices, take care that
the tools you’re using haven’t been attracted. Attractive fields may be harmful to data
stored on attractive media. Check your tool by pointing the tool with a screw. If the
screw is drawn to the tool, don’t use the tool.
1. Screws. Screws can become exposed if you over-tighten them with a screwdriver.
An exposed screw may mire within the screw hole, or it should not tighten firmly.
Discard exposed screws.
a. Flat head screwdriver. Don’t use a flat head screwdriver to get rid of a Phillips
head screw. Never use a screwdriver as a wrecking bar. If you can’t remove a
component, check to determine if there’s a clip or latch that’s securing the
component in position.
b. Philips screwdriver. Use a Phillips head screwdriver with crosshead screws. Don’t
use this kind of screwdriver to puncture anything. This can damage the pinnacle
of the screwdriver.
2. Soldering iron and stand. Always use a soldering iron stand after you aren’t
soldering to avoid burns or damage.
3. Crimping tool and wire stripper. When using the crimping tool and wire
stripper, you are doing not to have to squeeze super hard the handle because the
aim of it’s just to form a bend within the center of the crimp bead and to insulate
the wire.
4. Long Nose Pliers and Tweezer. After using the long nose pliers and tweezer
clean it properly with cleaning oil and rugs to avoid them from becoming dull and
rust.
5. Multi-tester and Lan tester. Always maintain the functionality and accuracy of
multi tester and lan tester to ensure the accurateness of measurement of any
things that you just shall measure.
6. Anti-static wrist strap. Always properly check the device before using it to make
sure that you just are free from danger and to avoid serious damage to the person
engaged in it.
12
Proper Maintenance of hand tools
To prevent tools from damage, we must properly maintain our tools to stay them safe
and usable condition.
Here are the subsequent requirements for tools and
equipment maintenance:
1.
Obtaining a duplicate of the upkeep schedule recommended by the
manufacturer.
2.
Ensuring that maintenance is performed as needed.
3.
Ensuring that the person(s) performing the upkeep are competent.
4.
Retaining records of maintenance/service conducted
5.
Specifying who is to blame for overseeing equipment maintenance and where
the records are kept
6.
Putting in a system for removal and tagging of damaged or defective tools and
equipment.
To ensure that tools and equipment remain in condition and last for a protracted
time, store them properly so it’ll be easy to search out when needed and are less
likely to be lost.
PPE (Personal Protective Equipment)
This is to shield you from hazard that will happened during working time at your
workplace. Always wear PPE equipment’s like gloves, safety glasses, protective mask
and rubber sole shoes.
