How to use

Install a compatible 18 V battery and select the appropriate socket for the fastener. Place the 1/2" drive square onto the nut or bolt and apply steady pressure while triggering the variable-speed control to reach the desired speed and torque. Reverse direction as needed for loosening. Allow the tool to reach operating speed before applying full torque and release the trigger when the fastener is secured or removed. After use, remove the battery and store the tool in a dry, safe place.

Recommendations

Use torque-limiting sockets or a torque verification method when working on components that require precise torque values. For extended work sessions, keep spare charged batteries available and follow manufacturer guidance for battery care to maintain performance and longevity.
