Caution! 1) Please wear safety gloves and glasses. 2) Please remove SMD from any adapator when replacing SMDT Tip. 3) Serrations may contain some debris. Placing a tip without removing any foreign particles may cause loose screws and possibly lead to tip and body breakage.

1) U se caution when tightening the head screws. 2) H old wrench parallel to SMD body when tightening. Forcing out wrench may cause screw hole breakage. 3) Tighten both screws to recommend torque settings in Tightening Torque chart (right).
