Driving larger screwsLarger screws require more torque and so they should be driven at slower speeds. |

Drilling or driving into tough materialsDrilling or driving into tough materials (e.g. metal or hardwood) requires more torque, and should be done at slower speeds. |

|
Please note: When drilling or driving at slower speeds, the motor is delivering a higher level of torque and can become very hot.
To ensure the motor does not overheat, remove the cordless drill driver from the work surface and run it at a high speed for a few seconds. This will allow the motor to take in air to cool itself down. |

Driving smaller screws or drilling into soft materialsDriving smaller screws or drilling into soft materials (e.g. softwoods or drywall) requires less torque so it can be done at a higher speed. |

Please note: Drilling and screwdriving at high speeds can cause the metal bit and screw to heat up.
If you are working with plastic at high speed, the screwdriver or drill bit can overheat and melt the plastic. To prevent this, work at a slower speed and check the material frequently. |
