The DEWALT DCS570 20V Circular Saw is known for its dependable cutting power, but like all tools, it can experience issues.
This article presents 6 common problems that users may encounter and provides straightforward fixes.
From lithium-ion battery malfunctions to cutting concerns, the following tips are designed to get you back to woodworking quickly.
1. Saw Fails to Start
A non-responsive DEWALT DCS570 Circular Saw is often the result of power supply issues. Begin by examining the battery’s connection to the saw; an improperly seated battery can prevent the saw from turning on.
Ensure the battery clicks into place securely in the battery slot.
To Do:
- Verify the battery’s charge level; a depleted battery will need recharging before use.
- If the battery is fully charged and the issue persists, test the saw with an alternate battery to rule out a faulty battery.
- Should the problem continue, it could indicate a more technical concern with the motor or switch. At this juncture, it’s advisable to seek the expertise of a certified technician to diagnose and remedy the internal electrical issues.
2. Poor Cutting Performance
When your DEWALT 20V Circular Saw isn’t cutting through the material as expected, the issue is often a dull blade.
A sharp blade is crucial for clean, efficient cuts.
To Do:
- Inspect the blade for sharpness. If it’s dull, you have the option to sharpen it yourself or take it to a professional for resharpening.
- If sharpening doesn’t solve the issue, or if the blade is already sharp, the saw’s alignment might be off. This requires the attention of a qualified technician who can adjust the saw accurately.
- Consider the age of your blade. Blades that have been in service for a long time may become dull beyond repair and need replacement. When installing a new blade, ensure it is securely fastened and balanced to prevent wobbling.
- Remember to use the saw correctly. Pushing the saw too hard can result in poor cuts and wear out the blade prematurely. Instead, allow the saw to cut at its own pace, utilizing its built-in torque for the best results.
3. Grinding Noise During Operation
A grinding noise emanating from your saw typically indicates that the saw is under excessive strain.
This sound should not be ignored as it can signal a serious issue.
To Do:
- Cease using the saw immediately to prevent further damage. Allow the saw to cool down completely, as overheating could be contributing to the noise.
- If, after a rest period, the grinding noise persists upon restarting the saw, the problem may lie within the internal gearing.
- At this point, it’s prudent to consult with a qualified technician. They can inspect the gears for wear or damage and perform necessary repairs to get your saw running smoothly again.
4. Overheating Issues
Overheating in the DCS570 is often a result of prolonged use without adequate breaks. This can strain the motor and other components, leading to potential damage.
To Do:
- Discontinue use immediately to allow the saw to cool down. This pause can prevent further overheating and protect the internal components.
- If the saw consistently overheats even after short periods of use, this could indicate an underlying issue with the motor.
- Under these circumstances, it’s advisable to seek the expertise of a qualified technician who can assess the motor’s condition and suggest a course of action, which may include repair or replacement.
5. Oil Leakage
Oil leakage is not a common occurrence and often points to a potential motor issue.
To Do:
- Refrain from using the saw if you notice any oil leakage. Continuing to operate it could cause further damage or pose a safety risk.
- The best course of action is to contact a qualified technician or an approved service center. They can diagnose the cause of the leakage and repair any damage to the motor or other internal components.
6. Stuck Brake
A stuck brake on your DEWALT circular saw can halt your work and raise safety concerns. The brake is designed to rapidly stop the blade from spinning when the trigger is released, preventing unwanted cuts or accidents.
To Do:
- First, ensure that the saw is switched off and disconnected from any power source. Safety should always be your top priority.
- Check for any visible obstructions or debris that might be causing the brake to stick. Sometimes, sawdust or small pieces of material can lodge in the mechanism.
- If the brake is still stuck after cleaning, inspect the brake mechanism for any signs of wear or damage. A stuck brake can sometimes be a symptom of a deeper mechanical issue.
- It’s not recommended to disassemble the brake mechanism yourself, as this could void your warranty or cause further damage. Instead, take advantage of your DEWALT warranty and contact a qualified technician or service center.
- Regular maintenance and cleaning after use can prevent many brake issues. However, if the brake on your circular saw becomes stuck despite your best efforts, professional service is the next best step.
Warranty
Your DCS570 Saw is backed by a comprehensive 3-year warranty, ensuring peace of mind and support when you need it most.
While it may seem like we often suggest seeking professional service, this recommendation is made to ensure you fully utilize the warranty services you’re entitled to.
To Consider:
- The warranty is in place to protect your investment. Undertaking repairs on your own, beyond basic maintenance such as blade replacement or sharpening, could invalidate this warranty.
- Should you encounter complex issues like motor or gear faults, it’s wise to resist the DIY impulse. Unauthorized repairs can lead to the warranty being voided, leaving you with the cost of repairs or the need to purchase a new saw.
- Think of your warranty as a valuable asset. It’s there to save you time and money, much like the saw itself is designed to streamline your woodworking. When an issue arises that’s covered by the warranty, taking advantage of this provision is the smart and economical choice.
