Chuck Slipping

A slipping chuck can make drilling difficult and reduce accuracy.

Possible Causes

• Worn chuck jaws
• Dirt or debris inside the chuck
• Incorrect drill bit installation
• General wear from heavy use

Resolution

• Remove the accessory and clean inside the chuck.
• Reinstall the drill bit and tighten correctly.
• Check the chuck jaws for visible wear.
• Replace the chuck if it no longer grips securely.

Hammer Function Not Working

The drill rotates but produces little or no hammer action.

Possible Causes

• Hammer mode not fully selected
• Worn hammer mechanism
• Faulty mode selector
• Internal dust build-up

Resolution

• Ensure hammer mode is fully engaged.
• Rotate the selector through all available settings.
• Clean around the selector switch.

If the issue persists, the hammer assembly may require servicing.

Reduced Drilling Performance

The drill struggles to drill through materials it would normally handle with ease.

Possible Causes

• Worn gearbox components
• Motor wear
• Incorrect drill bit selection
• Excessive pressure during use

Resolution

• Check the drill bit is sharp and suitable for the material.
• Allow the tool to work at its own pace.
• Listen for unusual gearbox noises.
• Arrange servicing if performance continues to decline.
