Variable-Speed Trigger Switch
Your tool is equipped with a variable-speed
trigger switch. The tool can be turned "ON"
or "OFF" by depressing or releasing the vari-
able-speed trigger switch.
The variable-speed trigger switch delivers high-
er speed with increased trigger pressure and
lower speed with decreased trigger pressure
(Fig. 4).
Two-Speed Gearbox Switch
Your tool is equipped with a two-speed gear-
box designed for drilling or driving at LO (1) or
HI (2) speeds. A slide switch is located on the
top of the tool to select either LO (1) or HI (2)
speed (Fig. 5).
LO (1) speed provides higher torque and
slower drilling speeds for heavy-duty work or
for driving screws, drilling large diameters, or
tapping threads. Use LO (1) speed for starting
holes without a center punch, drilling metals
or plastic, drilling ceramics, or in applications
requiring a higher torque.
HI (2) speed provides lower torque and faster
speeds for lighter drilling work. HI (2) speed is
better for drilling wood and wood composites.
NOTICE: To prevent gear damage, always allow the drill driver to come to a complete stop
before changing between HI speed and LO speed.
