Metabo KH 5-40 Hammer F.A.Q.

How do I change the drill bit on the Metabo KH 5-40 Hammer?

To change the drill bit, first switch off the tool and unplug it. Pull back the chuck collar, insert the new drill bit, and release the collar to secure it. Ensure the bit is firmly in place before use.

What should I do if the tool overheats during use?

If the tool overheats, stop using it immediately and let it cool down. Check for any blockages in the air vents and ensure the tool is not overloaded. Consider taking breaks during extended use to prevent overheating.

How can I maintain the Metabo KH 5-40 for optimal performance?

Regularly clean the tool by removing dust and debris. Lubricate moving parts as per the user manual, and check the power cord and plug for any damage. Store the tool in a dry, safe place to avoid moisture damage.

What is the proper way to use the hammer function on concrete?

Set the tool to hammer mode and use the appropriate drill bit for concrete. Apply steady pressure without forcing the tool and let the hammer mechanism do the work. Use both hands for better control and precision.

Why is the drill not penetrating the material effectively?

Check if the drill bit is suitable for the material and ensure it is sharp. Verify that the tool is in the correct mode for the material being drilled. Applying excessive pressure can also hinder performance.

How do I reduce vibration while using the Metabo KH 5-40?

Ensure the side handle is securely attached and grip the tool firmly with both hands. Use the tool's vibration reduction features if available, and make sure the drill bit is appropriate and not worn out.

What to do if the tool suddenly stops working?

Check the power supply and ensure the tool is properly plugged in. Inspect the fuse or circuit breaker and replace if necessary. If the tool still does not work, it may require professional servicing.

Is it safe to use the Metabo KH 5-40 in wet conditions?

No, it is not safe to use the tool in wet or damp conditions due to the risk of electric shock. Always ensure the work area is dry and the tool is stored properly to avoid moisture exposure.

How can I ensure precise drilling with the Metabo KH 5-40?

Mark the drilling spot clearly and use a center punch to avoid bit wandering. Start with a smaller pilot hole if necessary, and maintain a consistent speed and pressure for accuracy.

What are the signs that the carbon brushes need replacement?

Signs include reduced performance, intermittent power, and visible sparking around the motor area. Regularly inspect the brushes and replace them when they are worn down to avoid damage to the motor.
