A technician needs to set up a variable-speed cordless drill/driver to install multiple fasteners flush into a delicate workpiece without over-driving or stripping the material. Arrange the steps in the correct order to properly calibrate the tool's adjustable torque clutch.
- 1Shift the mechanical gear selector switch to low speed (Gear 1) to ensure maximum torque and driving control.
- 2Rotate the adjustable torque clutch collar to a low number setting well below the estimated required torque.
- 3Drive a test fastener into a representative scrap piece of the workpiece material until the clutch mechanism slips.
- 4Increase the clutch collar setting incrementally until the fastener seats perfectly flush with the surface.
Answer
The correct sequence is: shift the mechanical gear selector to low speed, rotate the clutch collar to a low initial setting, drive a test fastener into scrap material until the clutch slips, and incrementally increase the clutch collar setting until the fastener seats flush.
Properly setting a drill/driver clutch requires first selecting low gear (Gear 1) for torque control, dialing the clutch collar to a low baseline setting, testing on scrap stock to observe where the clutch disengages, and stepping up the numbered torque collar incrementally until fasteners consistently seat flush.
