The tool speed can be controlled from the minimum to the maximum nameplate RPM by the pressure you apply to the trigger. Apply more pressure to increase the speed and release pressure to decrease speed. This accurate speed control enables you to drill without center punching. [. . . ] The amount of pressure to be used is dependent upon the type of material being drilled. Soft materials require less pressure while the hard materials need more pressure to prevent the drill bit from spinning. maintenance Service Preventive maintenance !WARNING performed by unauthorized personnel may result in misplacing of internal wires and components which could cause serious hazard.
