The DCF922 features a 1/2" square drive with a detent pin anvil. To install a socket, push the socket firmly onto the square drive until the detent pin engages the hole in the socket, securing it in place. To remove, pull the socket off the anvil while pressing the detent pin (if applicable, some detent pins are spring-loaded and only require pulling).
Instruccions de funcionament
-
Encès/Apagat
The tool is activated by pressing the trigger switch. The speed is variable depending on how far the trigger is depressed. Release the trigger to turn off the tool.
-
Control cap endavant/marrere
A forward/reverse selector switch is located above the trigger. Push the switch to the left for forward rotation (tightening) and to the right for reverse rotation (loosening). Position the switch in the center for a trigger lock to prevent accidental startup.
-
Selecció de velocitat i mode
The DCF922 offers 4 speed settings and specialized modes for various applications. Use the mode selection button (typically marked with an icon resembling gears or multiple dots) to cycle through the available modes.
Figure 3: Control Panel (Mode and LED Selection) The modes typically include:
- Precision Wrench™ Mode: Designed to prevent overtightening in forward and fastener run-off in reverse. In forward, the tool will pause before impacting to allow the user to stop. In reverse, the tool will reduce speed once the fastener is loose to prevent run-off.
- Timber Screw™ Mode: Optimized for driving timber screws, providing high efficiency.
- Velocitat 1 (Mode de baixa velocitat): Provides lower RPM and IPM for delicate applications or when precise control is needed.
- Speed 2 (High Speed Mode): Delivers maximum RPM and IPM for heavy-duty fastening and loosening tasks.
Refer to the display on the tool for the currently selected mode.
-
Llum de treball LED
The integrated LED work light illuminates the work area. A dedicated button (often marked with a light bulb icon) allows you to cycle through different brightness settings (e.g., Off, 25% brightness, 100% brightness).
