Recommended Complementary Products

This tool is sold without a battery or charger. Here are the essential accessories:

Care and Usage

First Use

Preparing your DCF961B impact wrench:

  1. Charge the Battery

    Fully charge a compatible DeWalt 20V MAX battery before first use.
  2. Install the Socket

    Insert the socket onto the 1/2 in hog ring anvil until it clicks into place.
  3. Choose the Speed

    Select one of the 4 speed settings based on the fastener, or Precision Wrench mode for greater control.
  4. No-load Test

    Trigger the tool with no load to get familiar with its response before real use.

Regular Maintenance

To maximize the lifespan of your impact wrench:

After each use:

  • Remove the socket and wipe down the tool to clear dust and debris
  • Check that the motor's ventilation slots are not blocked
  • Remove the battery if the tool won't be used for an extended period

Battery:

  • Recharge the battery before it's fully drained to extend its lifespan
  • Keep battery contacts clean and dry

Cleaning and Maintenance

Periodic maintenance:

  1. Anvil and Sockets

    Inspect the hog ring anvil for wear or excessive play, which can affect fastening accuracy.
  2. Housing and Handle

    Clean with a slightly damp cloth, never with water directly on the tool.
  3. Motor Ventilation

    Use compressed air to clear dust buildup from the ventilation slots, essential on a brushless motor.

Recommended products: dry cloth, compressed air.

Avoid: water, solvents, or submerging the tool.

Safety Precautions

For your safety:

  • Remove the battery before changing sockets: prevents accidental startup.
  • Use only impact-rated sockets: standard sockets can crack under this tool's high torque.
  • Wear safety glasses: debris can be thrown during fastening or removal.
  • Match speed to the fastener: too high a setting on a small fastener can damage or break it.
  • Never exceed the tool's rated torque: stay within 1200 ft-lbs to avoid damaging fasteners or the structure being worked on.

Storage Tips

Short-term storage:

Store the tool in a dry place, battery removed if inactive for more than a few days.

Long-term storage (1+ month):

Clean the tool, remove the battery, and store it in its case or a dry place away from dust.

Winter storage in Canada:

Lithium-ion batteries lose performance in the cold. Store the battery and tool at room temperature and avoid leaving them in an unheated vehicle.

Nos réponses à vos Questions sur la Clé à Chocs DeWalt DCF961B

What is the maximum torque of the DCF961B impact wrench?

The DeWalt DCF961B impact wrench delivers up to 1200 ft-lbs of maximum fastening torque and up to 1750 ft-lbs of breakaway torque. No-load speed ranges from 0 to 1200 RPM with up to 1890 impacts per minute.

Does the DCF961B include a battery and charger?

No, this model is sold as tool only. A DeWalt 20V MAX battery and compatible charger are required and sold separately, a practical option if you already own tools from the 20V MAX DeWalt lineup.

What sockets should I use with this impact wrench?

Use only impact-rated sockets built to withstand this tool's high torque. Standard chrome sockets can crack or shatter under the impact force. The 1/2 in hog ring anvil accepts standard impact sockets of that size.

What is Precision Wrench mode?

Precision Wrench mode adjusts impact power for better control during fastening and removal. It helps prevent overtightening a fastener and reduces the risk of it being ejected during removal.

What warranty covers this tool?

The DCF961B is covered by a 3-year limited DeWalt warranty, one year of free service, and a 90-day satisfaction guarantee. Équipement Industriel Polar adds its own 30-day satisfaction guarantee on top.

How do I maintain the impact wrench to extend its lifespan?

Wipe down the tool after each use and keep the ventilation slots clear with compressed air. Remove the battery during extended periods of inactivity and avoid any contact with water or solvents.

Does this impact wrench work well in cold Canadian winters?

The tool itself handles cold well, but DeWalt 20V MAX lithium-ion batteries lose performance in freezing temperatures. Keep the battery warm between uses and avoid leaving it in an unheated vehicle during winter.
