Power tools are essential equipment in a workshop. Whatever you use them for, they make your work more efficient and easier. However, a series of problems with power tools will arise over time. If you ignore them, they will shorten the lifespan of your power tools and reduce their performance.
This post examines five common power tool issues, their potential causes, and quick fixes for each. Additionally, we give some tips for power tool safety and maintenance.
5 Common Power Tool Issues & Fixes
This section guides you through the most common power tool faults, their potential causes, and quick fixes.
It Won’t Turn On
The power tool not starting is a common issue. There is no need to panic. Possible causes of failure to turn on include:
- Damaged electric cords or switches
- Dust and dirt accumulation
- Worn-out carbon brush
- The battery is old or dead
How to fix the power tool starting failure problem? First, inspect the cord for looseness, damage, kinks, tears, or cuts. For a cordless tool, ensure the battery is fully charged and replace it with a new one if it is old.
Then, you can test the power switch with a multimeter to see if it’s working. If the tool is powered on but not starting, check the wear of the carbon brushes. Replace them if necessary.
Battery Drain or Charging Issue
Unlike corded power tools, cordless tools rely on batteries for power. A healthy battery is key to their proper functioning. However, batteries do eventually reach the end of their lifespan. Possible causes of battery drain and charging issues include:
- The battery is aged or swelling
- Contacts are dirty or corroded
- Charger malfunction
In order to repair the battery problem, first clean the contacts and batteries with a dry cloth, and reinstall them. Then, perform a full discharge-recharge cycle to calibrate the capacity. If that doesn’t work, just replace the battery.
A tip for you: Store lithium batteries in a dry, cool place and avoid leaving them plugged into the charger for extended periods.
Burning Smell or Overheating
Any power tool will generate heat during operation, but if it overheats or you even detect a burning smell, you need to be vigilant. At this point, you must immediately disconnect the power source and wait for it to cool down.
Possible causes of burning smell and overheating include:
- Motor overload
- Belt breakage
- Blocked ventilation duct
- Worn-out brushes
If your tool is belt-driven, immediately check if the belt is worn out, cracked, or broken. When the belt breaks, it will produce a burning smell. At this point, the power tool will immediately stop working, even if the motor is still running. Replace it if necessary.
You should also check if the ventilation ducts are blocked with debris, and then clean them with a brush or air gun. At the same time, avoid prolonged operation at full load to prevent shortening the motor's lifespan.
Smoke & Fire
Smoke and sparks can be a very frightening power tool problem. In this case, immediately turn off the power and do not continue using it. Otherwise, it can cause very serious damage to you and your tools. Remember to wait for the tool to cool down before trying to fix the issue.
Check and clean the dust and chips within the power tool. If your tool has no burning debris, take apart the casing and check for heat damage, especially the brushes, motor, or batteries. If you can’t handle this situation, contact the service team for professional help.
Unusual Noise & Vibration
During the power tool time, noise and vibration are unavoidable. If a power tool produces abnormal vibration and high-pitched noise (screeching, knocking, or grinding sound), that’s a sign of trouble.
Possible causes of unusual noise and vibration include:
- Worn-out bearings
- Loose screws and parts
- Damaged gear
- Unbalanced blades and bits
Power off your device and make sure it is properly lubricated. Check the gears (if it has) for wear or damage. If yes, replace them. Then, tighten all the screws and parts of the power tool.
Gently shake the tool or saw blade by hand. If it wobbles noticeably from side to side, the bearing may be damaged and needs to be replaced. When reassembling the tool, ensure it is centered and securely fastened.
Power Tool Maintenance
If a machine is not maintained, a series of problems will arise over time. Therefore, regular maintenance is crucial to avoid power tool problems.
Through maintaining your machine, you can effectively extend its lifespan, avoid expensive repairs, save repair time, and ensure safer and more accurate operation.
The following are some power tool maintenance tips to keep in mind:
- Regularly clean any remaining debris, dust, and resin deposits from the tool surface.
- Maintain lubrication of moving components such as gears, spindles, and bearings to reduce friction and extend service life.
- Keep blades and bits sharp to reduce vibration and improve cutting efficiency and safety.
- Regularly check the power cord for damage, twisting, or peeling of the outer sheath.
Power Tool Safety
As we all know, power tools pose a significant risk. Improper operation can lead to injuries. Therefore, strictly observing the safety rules when using power tools can better ensure the operator's safety. Here are some power tool safety tips to keep in mind.
- Know your power tool before using it. Read the user manual or instructions carefully.
- Wear proper personal protective equipment, such as a mask, goggles, and ear protection.
- Check your work area and make sure it is clean, dry, and free of clutter.
- Power off or unplug the tool before making adjustments or changing blades and bits.
- Avoid excessive force to prevent motor load and blade kickback.
- Use proper accessories to avoid blade kickback and chip splatter.
- Maintain a stable operating posture and keep your hands away from dangerous moving parts.
- Don’t wear loose clothing or jewelry to prevent them from getting caught in the machine.
