Drill only action: For drilling in woods, metals, plastics or other non concrete materials.
Drill with hammer action: For drilling in concrete, asphalt, tile or other similar hard materials.
GEAR CHANGE SELECTION
Gear selection: The proper gear selection is directly related to the speed and torque required for various jobs. The following should be adhered to when selecting the proper gear:
Speed 1 = low speed with high torque
Speed 2 = high speed with low torque
Changing gears: Change gear position only with the motor at a complete standstill. To change gears rotate the gear selection lever. If you have difficulties changing from one gear to the other, turn the chuck by hand until the gears engage (Fig. 1).
