Two-Speed Gearbox Switch (Fig. 5)
Your tool is equipped with a two-speed gearbox designed for operating at low or high speeds.
The slide switch is located on the top of the tool to select either low (marked "1") or high (marked
"2") speed.
The low speed (1) provides higher torque and slower speeds for heavy-duty work or for driving
screws, drilling large diameters, or tapping threads. Use the low speed for starting holes
without a center punch, drilling metals or plastic, drilling ceramics, or in applications requiring
a higher torque.
The high speed (2) provides lower torque and faster speeds for lighter drilling work. The high
speed is better for drilling wood and wood composites and for using abrasive and polishing
accessories.
NOTICE: To prevent gear damage, always allow the tool to come to a complete stop before
changing between low speed (1) and high speed (2).
