Preventative Care Saves Money. Regular inspections, cleaning, and lubrication highlight emerging problems allowing for timely action before the tool breaks down completely, forcing you to purchase a new one.

Basic Maintenance Tips for All Power Tools
1. Keep the Manuals and Read Them
Manufacturers provide user manuals for all power tools. The manuals have instructions for proper operation, specific safety precautions, and a recommended maintenance schedule. You’ll find information on the type of lubricant to use, replacement part specifications, and much more. Keep all manuals handy for easy reference when something goes wrong while working with a tool.
2. Clean Tools Regularly
Don’t allow grime, sawdust, and metal to build up inside your power tools. Built-up grime can cause clogging and overheating, which can be dangerous and lead to breakdowns. Regular cleaning, preferably after each use, can minimize damage and significantly reduce the risk of breakdowns.
3. Inspect Every Tool for Wear & Tear
It’s a good habit to inspect power tools after each use. Check for worn and loose parts, and inspect electrical cords for signs of fraying, warn insulation, and improper grounding. Check batteries for cracks, swelling, and leaks. Routine inspections can catch problems early, preventing more costly repairs or replacements down the line.
4. Lubricate Moving Parts
Power tools have many moving parts. It’s essential to keep them operating smoothly by oiling them frequently. The manufacturer’s manual will have information on what oil to use. Tools like jigsaws, circular saws, and impact wrenches that involve high-speed or repetitive motion require regular oiling.
5. Store Properly
Expensive power tools shouldn’t be left in a pile at the end of a working day. To protect these advanced tools, store them in a dry place, preferably covered, to prevent rust or moisture damage. Proper storage protects tools and keeps them organized for easy retrieval when you need them.

Specific Care Tips for Every Tool Type
Follow these maintenance tips to ensure your tools stay in optimal condition for a long time.

- Inspect cutting and grinding discs and replace worn or damaged discs.
- Inspect the grind guard for cracks or damage and replace it if necessary.
- For lubrication instructions, consult the manufacturer’s manual.
- Check the grip. Ensure it’s not loose or damaged, as that can compromise control of the tool and potentially lead to accidents or injuries.
- If you have an rebarbadora with carbon brushes, replace them if worn down.
- Store grinders in a dry and cool place to prevent moisture from corroding it.
Sanders
- Disconnect the sander.
- Remove the dust bag, empty it, and use compressed air to clean it after each use.
- Check seals are intact, so no dust contaminates the motor.
- Inspect and clean dust extraction ports.
- Check sandpaper sheets and replace torn or worn sheets and discs.
- Lubricate moving parts with manufacturer-approved oils.
- Store sanders and sanding discs in a dry, cool place for protection.
Corded Tools
For all electrical power tools, always inspect cables and electrical cords for damage like cracks, folds, or fraying. Check that the insulation is intact. Also, check all plugs and connections. Fix or replace any faulty cords and plugs.
Cordless Tools
Most cordless power tools, such as serras de fita sem fio, are powered by Lithium-ion batteries these days. These batteries need specific treatment if you want to keep them powering your tools optimally. Take the following precautions:
- Don’t allow batteries to overheat. Don’t leave batteries in a hot place or in direct sunlight. Store them in a cool, dry place, ideally between 40°F and 80°F (4°C and 27°C), and away from humidity.
- Never allow the battery to run down completely. Avoid deep discharge, with the battery capacity below 5%, as it can damage the battery. When not in use, store the battery 50 – 70% full. If you charge it at a higher capacity, it will speed up internal oxidization.
- When charging, use the correct charger specifically developed for the battery. Disconnect the battery from the charger when you’re not using it. It is not advisable to leave the battery on the charger indefinitely.
- As a general practice, treat batteries with care. When handling them, be careful not to bump, drop, or damage them in any way.

How to Clean Power Tools
Cleaning power tools is an integral aspect of power tool maintenance – a clean tool operates more efficiently and is less prone to malfunctions.
For cleaning power tools, use these power tool cleaning methods:
Soft Brushes for Dust & Debris
Use a soft-bristled brush (like a small paintbrush or toothbrush) to dislodge dust, sawdust, and dirt from vents of tools like drills, sanders, and circular saws. These tools have many awkward spots that need cleaning. You don’t want to use a hard brush which can cause damage.
Compressed Air for Hard-to-Reach Areas
For internal spaces or tight corners where dust settles, such as inside cooling vents, motor housings, or switch mechanisms, apply short bursts of compressed air. Hold the can upright and at a safe distance. Work in a well-ventilated space and wear a mask to avoid inhaling dust.
Gentle Detergent for Surface Grime
To dislodge stubborn grime, use a rag with mild dish soap and warm water. Wring out excess water to prevent electrical components from getting wet. Scrub down dirty spots and grime.
Microfiber Cloths for Wiping Surfaces
If the tool isn’t very grimy, just wipe it down with a microfiber cloth, which is perfect for lifting fine dust and preventing scratches. You can also use it with water and detergent for more stubborn dirt.
Rust Remover for Corrosion
For rust spots on metal surfaces, apply a small amount of commercial rust remover or a homemade paste of baking soda and water. Leave it for a short while, then scrub gently with a wire brush or scouring sponge until all the dirt is removed. Wipe clean with a microfiber cloth.
Lubricant for Moving Parts
Once the tool is clean apply lubricant to moving parts, such as hinges, gears, or bearings. Use lubricant recommended by the tool manufacturer. Lubrication is crucial to ensure smooth running and longevity of the tool. Don’t use too much oil as it attracts dust and dirt, which is counterproductive.
Note: Avoid using water and harsh chemicals like bleach, ammonia, or solvents because of potential damage to seals, coatings, and electrical components.

Should You Service or Replace?
Even with proper and regular service, power tools eventually come to the end of their usefulness when it’s more cost effective to replace them than to service them. Knowing when to replace rather than repair can save time and money. Here are some signs that a power tool need replacing.
Obvious Damage
When you see cracks in the casing, broken switches, dented tool parts, or snapped cords, it’s time to let your beloved tool go. Even if it still works, the damage can render it unsafe to use, which is not worth the risk.
Reduced Performance
If your tool doesn’t work like before in terms of power, precision, or speed, even with regular cleaning and lubrication, it may no longer be fit for use. Diminished performance, such as slower cutting, weak battery life, or inconsistent torque, are signs that it’s time for a new tool. Besides, a compromised tool will limit the quality of your work.
Ruído ou vibração excessivos
Unusual sounds or strong vibrations are usually signs of worn bearings, misaligned parts, or motor fatigue. If your tool makes unusual sounds and shakes violently, it may be time to stop using it.
Repeated Breakdowns
If a tool constantly breaks down, it probably has a permanent issue that will always cost money to repair. Rather than hoping it will work well next time and wasting money on repeated repairs, invest in a new tool.
Outdated Technology
Modern power tools are often lighter, more efficient, and have features that improve accuracy, safety, and battery life. If your older tool is missing features like brushless motors, dust extraction compatibility, or electronic speed control—and can’t keep up with current demands—it might be time for an upgrade.

Maintenance Frequency Schedule
Establishing a maintenance schedule that allows for regular inspections, cleaning, lubrication, and repairs is important. Keeping to a maintenance schedule ensures your tools last longer and perform optimally. How often these tasks need to be performed depends on the type of tool and how often you use it. Here are some general guidelines.
Inspeção: Inspections must be done regularly. If you use a tool often, conduct an inspection at least once a week.
Limpeza: If you use the tool frequently, clean it at least once a week. If you use it less often, clean it after each use or at least monthly.
Lubrication: Consult the manual for the lubrication schedule recommended by the manufacturer, which is usually monthly or after heavy use.
Blade Sharpening: For tools with blades, sharpen them as soon as you notice signs that the blades are becoming blunt, such as such the tool struggling to cut smoothly. Dull blades make your work harder and can cause the tool to overheat, increasing the risk of accidents.
Battery Care: Consult the manual and follow manufacturer guidelines for charging and storage. If the tool is used daily, inspect the battery once a week.
