The document discusses hardware tools used for computer system servicing. It identifies four types of hardware tools: 1) ESD tools like anti-static mats and wrist straps to prevent electrostatic discharge, 2) Hand tools like screwdrivers and pliers, 3) Cleaning tools like lint-free cloths and compressed air for cleaning components, and 4) Diagnostic tools like multimeters for troubleshooting issues. The document emphasizes selecting the proper tool for each task and observing safety practices, such as using manufacturer guidelines and wearing protective equipment, when working with tools.

To selectthe besttool fora job,keepinmindthe followingguidelinesforthe propertool selection.
 Learn andunderstandthe requirementsof the jobtobe performed.Afteranalyzingthe
requirements,planonhowtoaccomplishthe jobbyformulatingaseriesof manageable tasks.
 Trainingandexperienceinthe properandsafe usage toolsisnecessaryinorderto selectthe best
tool for a certaintask.Understandingthe manufacturer’smanual foraspecifictool isalso
important.
 All the correspondingpartsof a tool as perthe manufacturer’sspecificationsmustbe takeninto
account duringthe selectionprocess.The expendable partsshouldalsobe selectedandusedbased
on the instructionsinthe manufacturer’smanual.
Safety Use of Tools
Observe the five (5) basicsafetyrulestopreventhazardoussituationswhile workingwithtools.
1. Use the righttool for the job
2. Operate the tool accordingto the manufacturer’smanual
3. Examine eachtool fordamage before andafteruse
4. Wear the properprotective equipment
5. Keepall tools ingoodconditionwithregularmaintenance
HARDWARE TOOLS
The computertool kit isa set of hardware toolsthat are necessaryinrepairingacomputer.Hardware
toolsare categorizedintofour(4) groups;Electro-StaticDischarge (ESD) tools,Handtools, cleaningtools,and
Diagnostictools.

TOOL DESCRIPTION
An Anti-staticmat protects a person or a device especiallythe PC from an electrostatic
discharge or ESD.
The Wriststrap helpspreventESD damage to a PC.
The Anti-Staticwrist wrap is like a braceletthat wraps around an individual’swristand
has a cord that attaches to a computer.
An Anti-staticbag is usedto store or transfer electrostaticsensitive equipmentand
preventsstatic electricityinside the bag.
