Identify the issue

To inspect the demolition hammer and identify the issue, start by visually examining the tool for any visible damage or irregularities. Look for signs of wear, loose or broken parts, or any unusual sounds or odors. For example, check for a cracked casing, a loose handle, or a burning smell. Additionally, test the functionality of the hammer by trying different features and observing any malfunctions or abnormal behavior.


Check power supply

To ensure that the demolition hammer is properly connected to a power source and that the power supply is functioning correctly, follow these steps:

  1. Check the power cord: Make sure the power cord is securely connected to both the demolition hammer and the power outlet. Ensure that there are no visible damages or frayed wires on the cord.
  2. Inspect the power outlet: Verify that the power outlet is in good condition and functioning properly. Test it by plugging in another electrical device to confirm if it is supplying power.
  3. Reset circuit breaker or fuse: If the power outlet is working but the demolition hammer still does not have power, check the circuit breaker or fuse box in your building. Locate the breaker or fuse corresponding to the power outlet and make sure it is not tripped or blown.
  4. Test with another outlet: If all the above steps have been followed and the demolition hammer still does not have power, try plugging it into a different power outlet. This will help determine if the issue lies with the power supply or the tool itself.

Inspect power cord

To inspect the power cord, follow these steps:

  • Examine: Inspect the entire length of the power cord, looking for any signs of visible damage or fraying. Check for any exposed wires or broken insulation. For example, look for cuts or tears in the cord.
  • Replace: If you detect any issues with the power cord, it is important to replace it. Do not use a damaged or frayed power cord as it can pose a safety hazard. Purchase a new power cord that is compatible with your device and make sure to follow the manufacturer’s instructions on how to install it.

Check trigger switch

To test the trigger switch for proper functionality, follow these steps:

  1. Press the trigger switch repeatedly: Press the trigger switch on your device multiple times, ensuring that each press engages and disengages the switch smoothly. The switch should respond consistently and without any hesitation.Example: Press the trigger switch on your power drill five times in quick succession. Observe if the drill activates and deactivates promptly with each press.
  2. Check for any irregularities: Pay attention to any signs of malfunction such as a sticky or unresponsive trigger switch. A faulty switch may feel loose, get stuck, or exhibit inconsistent behavior.Example: Press the trigger switch on your hairdryer and note if it gets stuck in the “ON” position or if it requires excessive force to activate.
  3. Consider contacting customer support: If you encounter any issues with the trigger switch, especially if it consistently fails to function or exhibits erratic behavior, it may require replacement. Refer to the manufacturer’s instructions or contact customer support for further assistance.Example: If the trigger switch on your power sander is unresponsive or fails to activate the device, consult the user manual for instructions on how to contact the manufacturer’s customer support.

Inspect carbon brushes

  1. Remove the carbon brushes: Carefully detach the carbon brushes from their holders using a suitable tool, ensuring not to damage any surrounding components.
  2. Check for signs of wear or damage: Inspect the carbon brushes for any visible signs of wear, such as reduced thickness, frayed edges, or excessive dust buildup. Look for any signs of damage, such as cracks or broken sections.
  3. Replace the brushes if necessary: If the carbon brushes show significant wear, are damaged, or have reached the minimum recommended length, remove them completely from the holder and replace them with new ones of the same type and size. Ensure proper alignment and fit to avoid any issues during operation.

Examine motor

Inspect the motor by visually examining it for any signs of damage, such as cracks, dents, or loose components. Look for any signs of overheating, such as discoloration or a burnt smell. Listen carefully for any unusual noises, like grinding, clicking, or squealing. If you notice any issues during your inspection, it is important to consult a professional for further assistance. For example, if you see a cracked casing or notice the motor emitting a burning smell, contact a qualified technician immediately.


Check vibration dampers

Inspect the vibration dampers thoroughly for any visible signs of wear or deterioration, such as cracks, tears, or deformation. If any damage is noticed, immediately replace the dampers to ensure optimal performance and prevent further damage to the equipment. Regularly checking and replacing worn dampers will help maintain smooth operation and enhance the longevity of the system.


Clean and lubricate

Thoroughly clean the demolition hammer using a brush or cloth to remove any debris or dirt. In addition, apply the recommended lubrication to all the moving parts of the hammer as specified by the manufacturer.


Test functionality

To test the functionality of the demolition hammer, follow these steps:

  1. Plug in the power cord securely.
  2. Put on appropriate safety gear including gloves, safety goggles, and ear protection.
  3. Position the demolition hammer on a stable surface.
  4. Activate the power switch and apply gentle pressure to the desired surface.
  5. Observe the hammer’s performance, ensuring it delivers the expected power and operates smoothly.
  6. Repeat the process on different surfaces and at various angles to thoroughly test the functionality of the demolition hammer.

Seek professional assistance if needed

If the troubleshooting steps do not resolve the issue, or if you are unsure about performing any repairs, contact a professional for assistance. Consult a qualified technician who can provide expert guidance and diagnostics.

Necessary Equipment

  • Demolition hammer
  • Screwdriver
  • Multimeter
  • Cleaning brush
  • Lubricant
  • Replacement carbon brushes
  • Replacement parts (if necessary)

Effective Troubleshooting Techniques

  • Check the power source: Ensure that the demolition hammer is properly plugged into a functioning power outlet. Use a voltage tester to verify if there is adequate power supply to the tool
  • Inspect the power cord: Examine the power cord for any visible damage or frayed wires. If any issues are found, replace the power cord to prevent electrical hazards
  • Examine the carbon brushes: Carbon brushes are crucial components of the demolition hammer’s motor. Over time, they wear down and may require replacement. Inspect the brushes and replace them if they appear excessively worn or damaged
  • Verify the trigger switch: A faulty trigger switch can prevent the demolition hammer from operating properly. Ensure the switch is engaging and disengaging smoothly. If not, the switch may need to be replaced
  • Check for clogged vents: Demolition hammers have vents to keep the motor cool. These vents can become clogged with dust and debris, affecting the tool’s performance. Clear any obstructions from the vents using compressed air or a soft brush
