Maintenance of Electrical Tools and Equipment

To ensure that your electric tools work when you need them, you must take proper care of them. A good routine of maintenance for your tools is one thing that you can do to make sure that the tool you need is working when you need it.

Basic Maintenance

Clean out the Dust

To make sure that your electric tools are ready to go when you are, 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.

Check the Cord

Look for tear/cut insulator 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.

Use the right tools 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.

Protect your 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 a supervisor or instructor immediately.

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.

Storing your tools

Keep your electric tools stored in their original cases and containers. This will keep them free of dust and dirt while they are not being used.

Personal Protective Equipment

Personal Protective Equipment (PPE) are gadgets to protect workers from injury or illness caused by having contact with the dangers/hazards in the workplace whether they are chemical, biological, radiation, physical, electrical, mechanical and others.

These are the common Personal Protective Equipment gadgets:

Googles

Goggles are the primary protectors intended to shield the eyes against liquid or chemical splash, irritating mists, vapors, and fumes.

Rubber Insulated Gloves

Form the first line of defense to protect against contact with any energized components or electrical lines.

Working Boots

A pair of safety shoes (also known as safety boots) is personal protective equipment (PPE) for foot protection at workplaces

Hard Hats/Helmets

A hard hat is an article of personal protective clothing (PPE) used to protect the head from falling objects, impacts from falls, and other types of head trauma.

Working Pants

By wearing specially designed work pants, you can reduce your chances of suffering injuries to your legs and knees from common workplace hazards.

Electrician’s Different Working Outfit with Personal Protective Equipment

REMEMBER

Personal protective equipment should be taken cared as of the other tools and equipment. Wipe your helmet, gloves, safety shoes before keeping it.
It should also be cleaned, kept in proper tool rack/cabinet.
It should be stored in dry places so that it will not have mold build-up.
Over-all suites should be washed regularly so that perspiration and other dirt will be washed clean.

Classification of non-functional and functional tools

Tools are very useful to us in our homes especially to our job. But tools that are no longer functional may cause harm.

A. Make an inventory of functional and non-functional tools in your shop.

B. Classify your tools according to is function.

Methods of identifying Non-functional tools and Equipment

1. Visual inspection-It refers to the visual observation of an expert on the appearance of the tools and equipment.

2. Functionality-Vibration or extra noise from the operation means problems on parts and accessories started to develop.

3. Performance-When there is something wrong with the performance of either hand tools or equipment they need an immediate repair or maintenance.

4. Power supply (for electrically operated only)- Failure to meet the required power supply, malfunction will occurs in the part of hand tools or equipment.

5. Person’s involved. It refers to the technical person who has the knowledge and skills about the technology.

Non-functional tools and equipment are those that are not able to perform its regular function because of impaired and damage part. Examples of these are the following:

Hammer with a broken handle
Screw driver with a broken handle
Long Nose Pliers with damage jaw
A broken/cut foot rule
Electrical equipment with damage cord

Functional tools and equipment are those that are in good condition and can perform its regular functions.

Perform Basic Preventive Maintenance

Lubricants

A lubricant is a substance introduced to lessen friction between moving surfaces. It may also transport external particles. The property of reducing friction is known as lubricity.

Types and Uses of lubricants

1. Anti-rust lubricant spray:

loosen rusted part
cleans and protect
drives out moisture
stops squeaks
free sticky mechanisms

2. Wire Pulling Lubricant:

does not damage insulation
cling to wire and dries to a slippery film
suitable for use with wire or cable covered with rubber (t, thw, thhn, etc)

3. All Purpose Anti Rust Lubricant:

anti-rust
lubricating
rust removal
decontamination
conductance

4. Lubricant Oil and Engine Oil:

lubricating the gear
cleans and protect
drives out moisture

5. Silicon Lubricant:

heat stable
lubricates
protects
reduces friction
water repellent

REMINDERS:

A good lubricant possesses the following characteristics:

High boiling point
Low freezing point
High viscosity index
Thermal stability
Corrosion prevention
High resistance to oxidation

Solvent

Solvent is a component of a solution that dissolves solute and is usually present in large proportion or amount. It can be classified as polar and non-polar. Polar solvents are solvents which dissolve/are soluble in water; while non-polar solvents are solvents which do not dissolve/are insoluble in water. Solvents are usually used for cleaning in workshops. They are water, gasoline, kerosene, thinner and detergent soap.

Kinds of cleaning solvent based on their solubility in water:

Uses of Cleaning Solvents:

5's Approach in Workshop keeping:

5’S is a reference to a list of five Japanese words translated into English. This is an approached of organizing and managing the workplace and work flow with the intent to improve efficiency by eliminating wastes, improving flow of production, reducing process delays.

Why Maintain Inventory of Tools and Equipment

The most significant point to think at the start of your career is to acquire branded tools. They must be made out of high-quality steel and manufactured for precision. Special consideration is given to balance so that the tool/equipment will be properly maintained and prevent loses. Since the technician must work with his tools daily, regular inventory of tools/equipment is very significant.

The initial cost of a minimum number of tools is high but there is accompanying warranty guarantees satisfaction and many years of service. It is better, in the long run, to start with a few cautiously selected tools that will take care of your most common needs and then slowly build-up to a complete set. It is sometimes hard to identify and memorize the huge number of tools and equipment in the workshop, maintaining the inventory record is of great value.

Maintaining and Storing Tools and Equipment

Important aspect of any business is the maintenance and storage of tools and equipment. The investment in tools and equipment is a significant part of the overhead expenses in any operation. Proper selection and maintenance of equipment are important factors in managing business. Selecting the proper tool for the job and using the tool properly will increase efficiency and reduce maintenance problems. Purchase tools, which are well-made and suited to the intended use. Commercial usage may entail more heavy duty demands on equipment.

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.

Power tools:

1. Read and follow the maintenance schedule in the owner’s manual for each piece of power equipment.

2. Change the oil.

3. Clean the air filter.
