TWO-SPEED GEAR CONTROL (See Fig. D)
The screwdriver has a Two-Speed Gear Control (2) designed for
drilling or driving at LO (mark is 1) or HI (mark is 2) speeds. A slide
switch is located on top of the screwdriver to select either LO or HI
speed. When using the screwdriver in the LO speed range, the speed
will decrease and the drill will have greater power and torque. When
using the screwdriver in the HI speed range, the speed will increase
and the screwdriver will have less power and torque.
Gear I
Low speed range: for screwdriving or working with small drilling
diameter.
Gear II
High speed range: for working with small screw.
Warning: To prevent gear damage, always allow the chuck
to come to a complete stop before changing the direction of
rotation or the Two-Speed Gear Control.
TORQUE ADJUSTMENT (See Fig. E)
The torque is adjusted by rotating the torque adjustment ring. The
torque is greater when the Torque Adjustment Ring(1) is set on a
higher setting. The torque is less when the torque adjustment ring is
set on a lower setting.
Make the setting as follows:
1 - 7 for driving small screws
8 - 11 for driving screws into soft material
