Optimized hydraulics offer 20% faster advance and 30% faster retraction speeds than previous generation tools. Patent pending Auto-Retract feature provides a user-selectable ON/OFF switch to enable or disable automatic cycle retraction. Auto-Retract can also be stopped mid-cycle to speed repeat operation. Brush-guard jaw protectors help prevent accidental contact with energized circuits. Pull-pin design provides quick change-over between cutting and compression jaws. Works with Makita LXT 18V Lithium-Ion Batteries.
