ADJUSTABLE TORQUE CLUTCH
(Tightening Power of Your Screwdriver)
See Figure 7.
When using your screwdriver for various driving
applications, it becomes necessary to increase or
decrease the power and torque in order to help
prevent the possibility of damaging screwheads,
threads, workpiece, elc. In general, power and torque
should correspond to the difficulty of the screw to be
driven. If torque is too high the screws may be
damaged or broken.
Note: Your screwdriver has been shipped with the
adjustable torque clutch set at the lowest torque
setting.
TO ADJUST TORQUE
See Figure 7.
■ Locate arrow on torque adjustment cap,
■ To increase torque, rotate torque adjustment cap
in the direction of the arrow. When cap stops
rotating, you have reached the highest torque
setting. To decrease torque, rotate torque adjust­
ment cap in the opposite direction of the arrow.
When cap stops rotating, you have reached the
lowest torque setting.
Note: Remember the two speed feature (HI-LO) when
setting torque. The amount of torque will vary
depending on which speed setting you have your
screwdriver. Switching to LO speed will increase
torque and switching to HI speed wilt decrease torque.
