PREVENTIVE MAINTENANCE
— a predetermined work with the aim of
preventing the wear and tear or sudden failure of
equipment components.
— a schedule of planned maintenance actions
aimed at the prevention of break downs and
failures.
It is a service given for the purpose of
maintaining equipment and facilities in
satisfactory operating conditions by providing
systematic inspection, detection and correction
of failures either before they occur or before they
develop into major defects.
GOALS
•to keep working and /or extending the life of
the equipment.
• to get equipment working again sometimes
called repairing to prevent the failure of
equipment before it occurs.
• to preserve and enhance equipment reliability
by replacing worm components before they
actually fail.

• Make sure your computer is turned
off before you begin the cleaning
process.
• A computer on the ground attracts
more dust than one elevated on a
platform.
• Static attracts dust. Wiping down
your computer with a solution of one
and half vinegar and one and half
water will minimize static.
WHAT YOU CAN
CLEAN?
 Computer Case
 Computer Mouse
 Keyboard

 Monitor Casing
 Inside of the Computer
 Printer
STEPS IN
CLEANING
COMPUTER CASE
Benefits: Improves the overall appearance of your computer.
Note: Don't put too much liquid on the cloth where it might drip through
any openings and into the inside of the computer.
1. Turn off the system.
2. Unplug the system unit power connector from the wall
outlet (power supply).
3. Spray a Gentle cleaner (Alcohol) on hair free cloth.
4. Then clean it slowly.
MOUSE
.
1. Shutdown the PC.
2. Remove the mouse cable from its connection at the back
of your PC.
3. Spray Isopropyl Alcohol onto a lint-free cloth then wipe
the mouse.
4. Reconnect the cable to the computer.
5. Turn ON the PC and see that if it is activated.
KEYBOARD
Benefits: Cleaning your computer keyboard will not
only result in sticky-free keys but also ensure that your
keyboard will continue to function properly by
removing dirt, dust and other particles that can
damage the keyboard's circuits.
.
Note: Purchasing a keyboard cover or protector will protect your keyboard from dust
and any unexpected spills that may occur.
While working on my PC, something (liquid) Spilled into the keyboard.
1. Remove the keyboard cable from its connection at the back of the PC.
Do not wait, you need to cut power to the device in order to avoid a
possible short circuit.
2. Shutdown the PC using the mouse [start>turn off computer ...].
3. Tip the keyboard upside down and drain out as much of the liquid as
you can.
4. Try to dry the inside part of the keyboard properly by using blow dryer
or direct sunlight.
5. Reconnect the keyboard cable to the computer.
6. Power up the computer and manipulate the keyboard to assure proper
functioning.
DVD or CD-ROM DRIVE
Benefits: Prevents disc read errors.
1. Take a clean cotton cloth and dampen it with warm water.
2. Wipe the disc from the center towards the edge of the CD (wiping along the
track of the disc can cause scratches).
3. Prepare the CD cleaner kit.
4. The CD cleaning DISC has two soft brushes: dry and wet.
5. Turn over the disc and drop one of the cleaning fluids on the brush.
6. Insert the cleaning DISC into CD-drive like you would insert an ordinary disc.
7. Try to open the CD Drive from "My Compute: and allow the CD to operate.
8. The cleaning Disc will automatically clean the CD heads with the picture
displaying.
HARD DRIVE
Benefits: It takes a skilled technician to physically open up and clean a hard drive, but
your computer's performance can be optimized by doing such things as clearing out
unnecessary files on your hard drive.
1. Uninstall any programs that are outdated or unnecessary (if you aren't sure if you
need the program for your computer to run it's best to just leave the program as
is) and go through your folders and delete any files (pictures, mp3's, text
documents...) that you don't have a need for.
2. Empty your "Recycle Bin".
3. Run ScanDisk which checks and repairs disk errors.
4. Run Disk Cleanup which automatically deletes temporary files stored on your
computer.
5. Run Disk Defragmenter which optimizes your hard drive by rearranging programs,
files, and unused space which results in files opening quicker and programs
running faster.
MONITOR SCREEN
Benefits: A clean screen on your monitor gives you a clearer view of the items displayed
on your computer.
1. Turn off the monitor
2. Dampen a clean soft cotton cloth with water and gently wipe the
screen starting from the top of the screen to bottom wiping in a
downward motion.
NOTE:
- For LCD (laptop and flat panel) screens be careful not to press too hard or else you may damage the
screen.
- Using a paper towel or dirty cloth can scratch the screen.
- Using methyl chloride, acetone, ethyl acid, ethyl alcohol or ammonia-based cleaners can damage the
screen,
- LCD monitors are especially sensitive to these agents.
MONITOR CASING
Benefits: Improves the overall appearance of your computer.
1. Turn off the monitor
2. Dampen a cloth or paper towel with a mild cleaning agent and
wipe down the casing, especially the top as this is where most of
the dust tends to be. Don't put too much liquid on the cloth
where it might drip through the holes and into the computer
monitor.
3. Use a can of air and blow in the holes to get the any dust that
may be in there out (Alternatively you can use a vacuum cleaner
and suck the dust out).
COMPUTER INSIDE
Benefits: Removing dust from the computer vents
increases the internal air circulation. Dusting the inside
of your computer also prevents it from overheating.
.
1. Turn off and unplug the computer.
2. Remove the casing of the computer (directions should be in your computer
manual). It is recommended that you bring the computer outside at this point
because in the next step there'll be a lot of dust coming out of your computer.
3. Use the can of air to clean out the dust from the vents and the fan in the back
of the computer.
4. Use a can of air to blow the dust out of the computer going in one direction
while using short bursts of air (you want to clean all the circuit boards,
underneath the motherboard, the bottom of the case, get rid of dust on any of
your drives and blow air into the power supply box). You want to try to get as
much dust out of the computer as you can, if there is dust on the inside of the
case you should try to get that out of there as well. Try to avoid any direct
physical contact with any circuits in the computer.
5. Put the case back on.
PRINTER
Tip: Search for terms like printer maintenance, printer cleaning, and troubleshooting. Use only
the cleaners that your manufacturer recommends and clean only recommended areas of your
printer.
1. Turn your printer off before cleaning.
2. Clean the outside of your printer with a moist, lint-free cloth. Flour
sacking or 100% cotton white t-shirt material works well.
3. Usually a solution of one part vinegar and one part water is safe to use,
but when moistening a cloth, be sure to wring out all the excess.
Distilled or RO (reverse osmosis) water minimizes mineral residues. If
you do use a prepared cleaner, make sure it is safe for both electronics
and plastics.
4. Always moisten the cloth. Never spray an aerosol directly onto your
printer.
GENERALIZATION
EVALUATION
1. What is Preventive Maintenance?
2. Give the tools/materials that are
needed in cleaning the pcs.
3. Write down the steps of cleaning a
computer component.
