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) Use caution when tightening the head screws. 2) Hold 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).
