What Do You Already Know?
Let us determine how much you already know about maintaining tools and equipment. Take this test.
What Do You Need To Know?
Read Information Sheet 1.1 very well then find out how much you can remember and how much you learned by doing Self-check 1.1.
Maintaining Tools
To avoid accidents in the work place due to incorrect use of hand tools, it is a must that you understand the proper use of these tools. Study and practice proper use and maintenance of tools to prolong their life span and of course to avoid accidents due to improper or misuse of such tools.
Proper Use, Maintenance and Storage Tools
The use of safety hand tools should be a key component of most school safety programs. An understanding of the hand tool’s intended use and environment, combined with proper tool selection, maintenance and storage, will greatly reduce the risk of harmful accidents.
The following are guidelines maintaining and storing tools.
Keep hand tools clean and free from ferrous or other contaminants.
Do not use hand tools in direct contact with acetylene, due to the possible formation of explosive acetyl ides, especially in the presence of moisture.
During normal use, all pliers and screwdrivers will progressively develop some damage to the striking faces of screwdrivers or the cutting edge and striking end of pliers. As part of the normal operating and safety procedures, these tools should be returned to the workshop, as with steel tools, to have the faces Information Sheet 1.1 Read Information Sheet 1.1 very well then find out how much you can remember and how much you learned by doing Self-check 1.1.

Do not used hand tools fitted with wooden handles in places where the handles may dry out and shrink. This will increase the risk of the handle breaking or the head becoming loose.
Tools are designed for specific use. As with any tool. In addition to the probability that the tool will be damaged, this is a dangerous practice for the safety of the operator.
The accepted standards of safety and maintenance for common steel hand tools must also be adopted with non-sparking hand tools, in addition to any specific recommendations resulting from the alloys used.
When sharpening hand tools, follow normal safety procedures, such as the provision of eye and face protection, adequate extraction and dust collecting facilities.
Specifically, some tools require special care and maintenance due to their features and frequent use in any electronics or electrical job. Additional care and maintenance must be observed to the following:
Soldering iron
Always clean the tip before and after using.
Do not wash the tip just to speed up its cooling process after using it. It might damage the heating element and corrode the tip.
Soldering gun
Be sure to tighten the two nuts holding the tip before using it to have maximum heat transfer to its tip.
Never use a soldering gun in mass production assembly. It might be overheated and will consume more power compared to a soldering iron.
Desoldering tool
Keep it in good condition by cleaning its inside and apply a small amount of oil regularly.
Electric drills
These are tools that are used to bore holes in metals, wood, plastic or PCB in the process of electronic projects assembly. The most common of these are the mini drill powered from 12V DC voltage and the standard electric drill that can be connected directly to the 220 V AC power line.
Before using a drill, be sure to tighten the chuck jaw and secure the drill bit properly. The materials to be bored and the drill bit must be at 90 degrees angle to achieve efficient boring operation.
For more efficient and quality output with zero accident, the following Safety Pointers in Electronics Shop work are additional reminders for you to follow:
As a reminder, a good technician should always remember that “prevention is better than cure” to avoid accidents that might cause damage to tools, instruments, or even inflict injuries to himself while performing electronic jobs.
Accidents can be prevented by following the reminders listed below:
Be sure you are physically and mentally fit when working with electrical or electronic circuits.
Use only standard tools and instruments in performing any electronic job.
Always use the right tool for the right job.
Do not attempt to use tools or instruments you are not familiar with. Ask the assistance of your teacher or a person in authority in operating such unfamiliar electronic gadget.
Keep all tools and instruments in a safe place like tool box or tool cabinet to avoid accident and easy access when these tools are needed for use.
If accidents happened, report immediately to your teacher.
Keep all tools and instruments in good condition by following the steps of proper care and maintenance of electronic tools and instruments.
Your working area must be kept clean, in order, and free from any object that might hamper your work.
Keep flammable substance and materials away from your working area by keeping them in a safe place intended for them.
If possible, work with only one hand while working in a “live” circuit.
Keep yourself insulated from earth ground when working on power line circuit, since one side of the line is connected to the earth.
When your work is done, clean your working table and return all tools and instruments in their proper places.
Clean tools and equipment work more efficiently. At the end of each working day clean the tools and equipment you used and check them for any damage. If you note damage, tag the tool as faulty and organize a repair or replacement.
Electrical current can travel over oily or greasy surfaces. Keep electrical power hand tools free from dust and dirt and make sure they are free of oil and grease.
All workshop hand tools and equipment should have maintenance schedule. Always complete the tasks described on the schedule at the required time. This will help to keep the hand tools in safe working order.
How Do You Apply What You Have Learned?
Show that you learned something by doing this activity
Operation Sheet 1.1
I. Directions: Conduct a maintenance activity on the given hand tools with the following guide questions:
1. What will you do if a hand tool is damaged due to misuse?
2. You are working in an untidy work station, what will you do?
3. If the hand tools are oily or greasy, what is the proper thing to do?
Answer the above questions by filling in the matrix below. Do this on a separate answer sheet.
II. Instruction:
1. Observed your teacher as he/she demonstrates on how to maintain and store the hand tools properly. You will be grouped into five (5) and to be tested in the procedure in maintaining and storing hand tools.
2. After finishing each laboratory activity, your teacher will grade you.
3. You must get a score of 7-9 to get a grade (Very Good), for this laboratory activity. An assessment criterion will guide your teacher.
III. Direction: Make a matrix indicating the different hand tools grouped according to classification and their uses.
IV. Procedure in maintaining and storing of hand tools
1. Provide a safety cabinet for all the hand tools and assign a specific
area for each tool.
2. It should be cleaned before returning it to the tool rack.
3. Damage hand tools should be repaired.
4. Apply oil on all moving parts if possible.
5. Cover the sharp parts of the tools with a cork when not in use.
