OPERATION TWO-SPEED GEAR TRAIN See Figure 7. 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. NOTE: If you have difficulty changing from one gear range to the other, turn the chuck by hand until the gears engage. CAUTION: Never change gears while the tool is running. Failure to obey this caution could result in serious damage to the drill. QUICK MODE SELECTOR See Figure 8. The Quick Mode Selector allows you to quickly switch from drill mode to drive mode. In general, drill mode should be used for drilling and other heavy duty applications. Drive mode should be used for driving screws. Hammer mode should be used for hammer drilling.
