OPERATION
TWO-SPEED GEAR TRAIN (HI-LO)
See Figure 5.
The drill has a two-speed gear train designed for drilling or
driving at LO (1) or HI (2) speeds. A slide switch is located on
top of the drill to select either LO (1) or HI (2) speed. When
using drill in the LO (1) speed range, speed will decrease
and unit will have more power and torque. When using drill
in the HI (2) speed range, speed will increase and unit will
have less power and torque. Use LO (1) speed for high power
and torque applications and HI (2) speed for fast drilling or
driving applications.
