వేగం మరియు మోడ్ ఎంపిక
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.
- Speed 1 (Low Speed Mode): 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.
