What will cause a SDS rotary hammer burning?

 

A SDS rotary hammer can experience burning or overheating due to several reasons. Here are some common causes:

 

 

 

1. **Excessive Load:**

   Running the rotary hammer under heavy load or using it beyond its capacity for an extended period can lead to overheating. This often occurs when drilling into hard materials without proper tool adjustments.

 

 

 

 

2. **Dull or Improper Bits:**

   Using dull or incorrect drill bits can cause the rotary hammer to work harder, generating more heat. Ensure you use sharp, appropriate SDS bits for the material you are drilling.

 

 

 

 

 

3. **Faulty Bearings:**

   Worn-out or damaged bearings in the rotary hammer drill can increase friction, resulting in overheating. Regular maintenance and inspection of the tool's internal components are crucial.

 

 

 

 

 

4. **Power Supply Issues:**

   Inconsistent power supply or using an incompatible power source can affect the performance of the rotary hammer. Make sure to use the correct voltage and check for any fluctuations in power.

 

 

 

 

5. **Blocked Ventilation:**

   Insufficient airflow to cool the motor can lead to overheating. Check for dust, debris, or other obstructions in the ventilation channels, and clean the tool regularly.

 

 

 

 

6. **Continuous Use without Breaks:**

   Extended use of the rotary hammer without allowing it to cool down can contribute to overheating. Take breaks during prolonged operations to prevent the tool from getting excessively hot.

 

 

 

7. **Motor Issues:**

   Internal motor problems, such as a malfunctioning cooling fan or damaged windings, can lead to overheating. Professional inspection and repair may be required in such cases.

 

 

 

 

 

 

8. **Incorrect Lubrication:**

   Lack of proper lubrication in the gearbox or other moving parts can increase friction and heat generation. Regularly check and lubricate the tool as per the manufacturer's recommendations.

 

 

 

 

 

If you notice signs of burning, such as a burning smell, smoke, or discoloration of the tool, it's crucial to stop using it immediately. Continuing to use a overheated tool can lead to permanent damage. Consult the tool's manual for troubleshooting steps, and if the issue persists, seek assistance from a qualified technician or the tool manufacturer.
