How To Properly Maintain Your Power Tools

How To Properly Maintain Your Power Tools

Power tools can easily be the most expensive part of your DIY kit, and considering you’ve invested a lot of money into them, you want them to serve you for many years. Here are a few maintenance tips you should remember to ensure none of them let you down. 

Let Them Cool Down

Whether it be power tools, battery chargers, or anything in between, if it is getting too hot through overuse, always stop what you’re doing and let them cool down. Overheating can alter the performance of the tool, as well as cause irreparable damage in the long run. 

If you find your tools overheating regularly, invest in ones that are fitted with an anti-heating mechanism. If these are out of your budget, stick to letting them cool down before starting work again. 


Proper lubrication of most power tools can not only extend their lifespan, but prevent chaffing, overheating, and corrosion. However, remember to consult the user guide of the tool to ensure you are using the right kind of lubrication. 


From saw blades to drill bits, they can all only perform at their best if they are sharp. Taking the time to ensure every cutting or drilling attachment you have is sharp with ensure they work at their best, and lessen the load on the tool that is using them. 

If you have ever used a blunt knife to cut meat, you will know how much extra effort it takes; in the world of power tools, that extra effort can lead to overheating, and, in the worst-case scenario, a blown motor. 

Clean After Use

This is a simple tip, but one that makes a world of difference: always clean your power tools after each use. While dirt and grime can wear the tools down, too much dust or a drop of water in the wrong place can lead to severe internal damage. 

Because of this, it is essential to wipe down and clean every tool and attachment you used, no matter how big or small the job was; your pocket will most certainly thank you in the long run.  

Regularly Tighten Bolts & Screws

The efficiency and safety of your tools can be compromised if there is a loose bolt or nut. This typically happens after extended use, but can lead to severe problems that can jeopardise the integrity of the machine, as well as potentially causing you harm. 

Make it a regular habit to tighten and check every nut, screw, and bolt on all of your machines and tools to ensure they are tightened and sitting correctly. 

Cord Maintenance

Maintenance doesn’t just apply to the tool itself, but also to the cord attached to it. Constant moving, twisting, stretching, etc, can lead to the cord covering becoming damaged and eventually breaking. 

While there is no need to replace the tool entirely, keep an eye on your cords and use duct tape or electrical tape to cover any damage. If you have the skills and knowledge, replacing the cord is also an option. 

Replace Worn Parts

This is another fairly simple step to take to ensure your tools last for years: replace worn parts when needed. Depending on your DIY skill level and knowledge, you will most likely not be able to fully repair worn parts, therefore, replacement is the only option. 

However, it is important to note that worn parts should be replaced before they break, not after. You don’t want to risk damaging your equipment, or yourself, simply because you delayed the replacement. 

Proper Storage

Another crucial step in tool maintenance is to store them correctly. Most power tool kits will come with a storage case of some sort, but if they don’t, have a case or toolbox available to store them in. 

Proper storage will stop the tools from getting unnecessarily dirty, prevent corrosion, and also stop any sharp bits and blades from becoming worn down. 

Attachment Maintenance

Besides bits and blades, many of your power tools will have multiple attachments. Sander belts, oscillator attachments, etc., all need to be looked after just as much as your power tools and more important, accessories. 

This is also necessary because you will attach and remove these accessories regularly, which causes more wear and tear. 

Look After the Batteries

Don’t forget to look after your batteries and battery packs, too. Keeping them clean, charging them only when necessary, and replacing them when needed ensures they can perform at their best for as long as possible. 


Stop Work if the Tool Struggles

Finally, never continue to use a power tool when it is struggling to get a job done. This is a mistake that many new, and seasoned DIY’ers make, and it can lead to severe damage and outright failure of the tool you are using. 

If you are using it for a job it should be capable of doing, but it is struggling, stop what you are doing and assess what is going wrong. For example, is the drill bit not fit for the job, or is the battery too low, and you aren’t getting full power?; never force a power tool to do a job it isn’t strictly designed for.
