GEAR SHIFTING
Your tool is equipped with two separate gear
ranges, low gear 1 and high gear 2. Low gear
provides high-torque and slower drilling
speeds for heavy duty work or for driving
screws. High gear provides faster speeds for
drilling lighter work. To change speeds slide
switch, to the high 2 or low position 1 (Fig. 7).
ATTENTION: If your tool appears to be
running, but the chuck will not turn, check to
make sure the gear shifter is pushed fully into
desired setting.
MODE SELECTOR SWITCH
The mode selector switch allows the tool to
be set for various drilling or driving
applications. Turn the mode selector switch
right or left depending on the below
