5. Operating Instructions
Power Selection Switch (4-Speed)
The tool features a 4-speed power selection switch located on the base of the tool. Press the 'MODE' button to cycle through the four speed settings (1, 2, 3, 4) to match the application requirements. Each setting provides different RPM and IPM ranges for precise control.
Figure 2: Close-up of the 4-speed power selection switch and mode indicator.
Forward/Reverse Switch
The forward/reverse lever is located above the trigger. Push it to the left for forward rotation (tightening) and to the right for reverse rotation (loosening). Position it in the center to lock the trigger and prevent accidental startup.
Trigger Operation
Squeeze the trigger to start the tool. The speed is variable depending on the pressure applied to the trigger. The full-speed mode function allows the tool to reach full speed with less trigger pull.
Auto-Stop Modes
The XWT17Z includes 3 forward and 3 reverse auto-stop modes. These modes are designed to increase efficiency by automatically stopping the impact action under specific conditions, preventing over-tightening or allowing for controlled loosening.
Figure 3: The tool in use, demonstrating its innovative features like auto-stop modes.
Application Guidance
For fastening, select a lower speed setting initially and increase as needed. For nut-busting, the tool delivers up to 740 ft.lbs. of torque. Always ensure the socket is fully engaged with the fastener.
