Pro Tip: The “Reverse-First” Hack
Want to extend your tool’s life and work like a master technician? Most users overlook the ABR (Auto Bolt Release) potential beyond just safety.
The Pro Strategy: When working with old or slightly rusted bolts, don’t just blast them in forward mode. Briefly engage the Reverse Mode with ABR on for 2 seconds. The high-frequency impact in reverse “shocks” the threads and breaks the surface tension of the rust without stripping the bolt head. Then, switch to forwardโyou’ll find the bolt seats much smoother!
Bonus Hack: To maximize the 2.0 Ah battery, avoid “Trigger-Tapping.” The brushless motor is most efficient when held at a steady speed. Trust the tool’s torque management rather than pulsing the trigger manually!
