Lesson 1 Performing Basic Preventive Maintenance

What’s In

Hello again! Welcome back for another exciting lesson you are about to learn. In your previous lesson, you study about segregating defective tools, label defective tools, and reporting the list of defective tools.

In this lesson, you are about to learn lubricating tools and equipment. This module will guide you on the importance of lubricating tools and equipment as part of your learning adventure in conducting preventive maintenance of carpentry tools.

Notes to the Teacher

When teaching this lesson, the teacher must emphasize to the learners the value of maximizing the use of tools and equipment and save money to be used to other basic needs in the family. Taking care of tools will extend their usability. Therefore, care is also an important aspect to be considered by a carpenter. Teacher must press on this.

What is It

At this point of your module, you are now focusing on the substance of the lesson. Let’s get it on.

Importance of Repair

Repair plays an important role in reinforcing your home and workplace. Maintaining your tools and equipment can be a big help in the preparation of the repair and maintenance process. That is why, regular inspection of tools and equipment can help you become prepared when unexpected damage happen in your home and workplace.

Things to Keep a Watch

Defective tools can cause serious and harmful injuries. If a tool is defective in some way, do not use it. If tools and equipment are defective, attach an Out of Service tag with signature and date. Upon proof of repairs (a receipt), the tag will be removed and attached to the invoice for continuous monitoring.

Watch out for problems such as chisels and wedges with mushroomed heads, split or cracked handles, chipped or broken drill bits, wrenches with worn out jaws, and tools that is not complete, such as files without handles.

There are important things to remember for air, gas or electric power tools. Watch for problems such as broken or inoperative guards, insufficient or improper grounding due to damage on double insulated tools, no ground wire (on plug) or cords of standard tools, the on / off switch not in good working order, tool blade is cracked, the wrong grinder wheel is being used, and the guard has been wedged back on a power saw.

Conduct Preventive Maintenance of Carpentry Tools

Preventive maintenance is a routine maintenance process on a piece of equipment to lessen unnecessary or sudden breakdown. A Preventive Maintenance Plan is critical in any maintenance management program to avoid unplanned downtime and to increase productivity.

It requires planning and scheduling of maintenance on an asset. Correspondingly, it can be a big help to review data from previous inspection and maintenance reports.

There are three types of Maintenance:

1. Breakdown Maintenance: It is holding up until the equipment fails before repairing or servicing it.
2. Preventive Maintenance (PM):
   • Time-based or run-based. This includes occasional inspection, servicing, cleaning, or replacing parts to prevent unexpected failure.
   • Predictive. This includes regular monitoring of equipment in order to use important/expensive parts to the limit of their serviceable life
3. Corrective or Predictive Maintenance: Improving equipment and its components so that preventive maintenance can be completely reliable.

Here are some steps in conducting Basic Preventive Maintenance

Generally, cleaning, lubricating, and storing properly are basic preventive maintenance in tools and equipment. Below are some suggestions:

A. Hand tools

1. Clean dirt and debris from tools after each use.
2. Oil metal parts to prevent rust.
3. Lightly sand rough wooden handles and apply linseed oil.
4. Repair loose handles.
5. Sharpen blades of cutting tools.
6. Store tools in a clean dry storage area.
7. Protect surfaces of cutting tools in storage.

B. Electric Powered Tools and Equipment

1. Clean out the dust. To make sure that your electric tools are ready to go. Keep them clean and free of dust. Spend some time to clean out the dust every once in a while on your tools while they are inactive in storage.

   
   

2. Check the cords. Look for tear/cut insulators on the power cords on your electric tools. This will ensure that your electric tool can get the power that it needs to function without an accident and avoid electrocution.

   
   

3. Use the right tool correctly. Use tools correctly and for their intended purposes. Follow the safety directions and operating procedures recommended by the manufacturer. When working on a circuit, use approved tools with insulated handles.

   
   

4. Protect your Power tools. Keep tools and cords away from heat, oil, and sharp objects. These hazards can damage insulation. If a tool or cord heats up, stop using it. Report the condition to your teacher or an expert immediately.

   
   

5. Use double-insulated tools. Portable electrical tools are classified by the number of insulation barriers between the electrical conductors in the tool and the worker.

   
   

6. Storing Your Tools. Keep your electric tools stored in their original cases and containers. This will keep them free of dust and dirt while not in use.

   
   

7. Lubricate moving parts. Using lubricant helps maximize the life of tools and equipment and make the work more efficient.

   
   

8. Follow the maintenance schedule. Following the maintenance schedule of tools and equipment gives the care it needs and lengthens its lifespan.

   
   

Repair of Defective Carpentry Tools

Any carpentry tool is potential for being unsafe if it is defective or poorly manufactured. This doesn’t only apply to power tools used in carpentry such as table saws and drills, it can also be applied to simple hand-held tools, such as hammers, pile, or screwdrivers, as well. Depending on their industry, workers may also use very sophisticated, computerized machinery manufactured to its specifications but which also has to be well maintained throughout the life cycle of the tool or machine.

When workers use tools in the workplace, it shouldn’t be too much to expect that they have been manufactured to be safe when used as instructed and that they will operate as the manufacturer intends. And yet, when it comes to workplace accidents, defective tools and defective machinery are among the leading causes of serious injuries and fatalities.

Among some of the most common defects in carpentry tools include damaged or poorly manufactured, without the fluid necessary to run them, missing safety guards, attachments that do not connect to the tools securely, and many more.

These are steps in repairing defective carpentry tools:

A. Hand Tools

1. Inspect hand tools for damage checking.
2. Identify parts that are damaged. Based on the severity of the damage, decide if it is for repair or replacement.
3. Check for loose parts. Loose parts should be tightened.
4. Dull or blunt edges should be sharpened or replaced.
5. Remember that if the damage is beyond repair, it should be replaced.

B. Electric Powered Tools and Equipment

1. Inspect parts such as electric cords and connections of electric-powered tools for damage checking.
2. Identify parts that are damaged. Based on the severity of the damage, decide if it is for repair, replacement, or disposal.

What’s More

Preventive maintenance involves the systematic inspection of equipment where potential problems are detected and corrected to prevent equipment failure before it happens.

In this activity, you are going to read the text paragraph about preventive maintenance. The words you encounter in the selection will give you hint to solve the puzzle.
