TWO-SPEED GEAR TRAIN
See Figure 6.
The screwdriver has a two-speed gear train designed for
LO or HI speeds. A slide switch is located on top of the
screwdriver to select either LO or HI speed. When using
screwdriver in the LO speed range, speed will decrease
and unit will have more power and torque. When using
screwdriver in the HI speed range, speed will increase and
unit will have less power and torque. When drilling use 1/4
in. hex shank drill bits only. Maximum drill size is 1/4 in.
Use the HI speed setting to drill holes, and use the LO
speed setting for driving screws.
