To ensure a long life of any tool it is important to be attentive to its cleaning, spare parts and adjustments, especially if it is a circular saw since it is a precision machine that requires being in the best conditions to provide quality finishes. However, we must know how to perform proper maintenance, especially if we want it to have a long service life.
The best circular saws of 2020 are tools of great power and efficiency to make cuts, so they are essential in a carpentry workshop. However, at the time of use, it is possible that they accumulate dust and wood residues, which by increasing the heat from friction, make the cutting more imprecise, resulting in defective or poor quality finishes.
The number of times and the frequency to clean a circular saw depends on the use you give it since there is no regulation for maintaining it, nor an exact period of time to verify its condition. However, it is good to take into account some aspects for greater efficiency, such as the importance of cleaning the cutting blade, the most recommended cleaning implements and practices that you should avoid during cleaning.
Cutting blade maintenance
A dull, dirty or damaged blade may be more dangerous than a new one since the engine usually has less control over it and could decrease its life. Therefore, the most important thing to consider for the maintenance of a circular saw is to check the condition of the cutting disc, since it is the fundamental part of this machine.
If you use the tool eventually for specific projects, then it is advisable to clean it two or three times a year. However, you should check the status of it to confirm that it is still functional; this can be achieved by examining the tips of the teeth of the disc.
If the teeth are dull and you have a circular saw with a smooth steel blade, you can recover the edge with the use of a triangular metal file, while if the blade is made of hard steel, it must be sharpened professionally. In the event that the tips are broken, rusty or very dull, it is best to buy a new blade to avoid inconvenience and work with poor finishes.
Useful products to clean a circular saw
Although these tools are made with different materials, it is possible to perform maintenance with simple household cleaners, even many of these can be made by hand. One of those preferred by carpenters is detergents that have citrus fruits since they normally work to clean the carcasses and surfaces of different tools and subsequently the house, which means a great advantage of use.
In the event that you want to use this type of substance to clean the sheet of metal or steel, it is common to find cleaning detergents for circular saws in carpentry stores and hardware stores. In general, household cleaners recommended for the maintenance of carpentry tools have Easy Off, which is a multi-purpose component with concentrated cleaner and degreaser, in addition, it is not toxic and was originally used to clean industrial machinery.
If the ventilation slots are blocked by dust or grease, you should only remove the dirt with a dry brush with soft bristles, trying at all times to remove the dust from the slots and not push it inwards. You can also use the brush to remove dust from the sheet and other parts of the housing. Also, it is practical to use a damp towel for the same task and even to clean the power cord.
Prohibitions when cleaning a circular saw
It is important that you do not overdo it when using a cleaning detergent, so you should slightly dampen a towel with the liquid and then slide through the saw; however, it is advisable not to clean the cutting disc with any cleaner, since some may be abrasive
Similarly, it is important not to wet the interior of the tool under any circumstances, since water could damage its mechanism and sulfate some of its electrical parts, which are usually delicate maintenance and require professional treatment in the case of being affected.
However, surface dirt is not the only aspect that may need attention and revision, but also the screws and parts of its structure. In this case, you can perform a quick check before turning on the machine and adjust the screws if necessary.
You should not use any type of wire brush or sponge to clean the circular saw, as it could cause scratches and irreparable damage to the surface of the machine and the blade. Instead, you can use nylon utensils.
To extend the useful life of the tool you should avoid overheating, caused by keeping the blade for long periods of time on very hardwood since this can split the tips of the disc and could be shot towards you or another person.
Aspects you should consider before using a circular saw

The circular saws incorporate a screw to adjust the angle of cut, it is necessary that it be leveled correctly to avoid incorrect movements.
Then, it is advisable to verify that the casing that covers the cutting blade opens and closes correctly, also, the screw that holds the disc must be firmly tightened, in this way you will avoid accidental detachments and you will feel safer during the workday.
The next step is to check the condition of the power cable, taking care that it is not stripped or bent. In addition, the on and off switches must function optimally, since we can stop the engine when necessary. Finally, it is necessary to start the engine and verify that its operation is correct, as well as the drive of the speeds.
