1. Use the approriate drill for the application.

2. Tighten the drill bit in place with a chuck. A keyed chuck uses a rotary key to tighten and loosen the chuck. A keyless chuck is operated by hand.

   WARNING

   Risk of Injury

   The drill bit must fit tightly in the chuck before starting the drill. A drill bit that does not fit properly into the chuck may come loose and cause bodily injury.

   - Check that the drill bit fits tightly in the chuck before starting the drill.

3. Remove the rotary key before starting the tool.

4. Make sure the workpiece is securely fixed.

5. Always have a firm footing when drilling. Brace and position yourself carefully when drilling.

6. Always make sure there are no electrical wires or water lines behind the surface you are drilling into.

   Never drill a hole that is larger than the rated capacity for the drill.

7. Use the appropriate drilling speed for the application.

8. Start the tool by pressing the trigger.

9. Do not force the drill. If the drill slows down, change to a drill with more power, so that the drill bit can continue cutting smoothly.

10. If the drill gets caught in the material, release the trigger immediately, unplug the drill and remove the bit from the material.

When lubrication is recommended - only use lubricants recommended by Atlas Copco.
