Torque Adjustment

The numbered front collar allows you to select a fastening torque setting. Start with a low setting when driving screws and increase it gradually as needed to reduce the risk of damaging the screw head or workpiece.

The collar numbers represent adjustment settings, not specific torque values in newton-metres.

Chuck and Bit Changes

The drill features a 10 mm keyless chuck. Remove the battery, open the chuck, center the bit shank between the jaws, and tighten securely by hand.

Chuck size describes the capacity for holding an accessory’s shank. It does not specify the maximum drilling diameter in every material.

Batteries and Charging

Two removable rechargeable batteries are included, allowing you to alternate between use and charging. Slide the battery into the mount beneath the handle until securely seated.

Use the supplied charger and follow its instructions and charging indicators. Runtime depends on the workload, application, and battery condition.
