Mode selection (see Figure H)
Your tool is equipped with a speed control panel 3, located on the foot of the tool. It consists of the drive-control button, the “M” button, and LED indicators for working modes. The drive-control button is used to select among three modes to adjust the torque, rotation speed (RPM), and impact-speed (IPM) settings for an application. The modes 1, 2, and 3 are the only modes where the speed is controlled by the variable-speed trigger switch

To select the drive control mode:

First, check the active mode. Press the drive control button directly without touching the trigger switch. The LED indicator below the mode number will illuminate to indicate the active mode setting.
Press the drive-control button briefly (less than 0.5 seconds) to cycle through the 3 modes. Each press changes one torque level. See more details in the chart below.“A” is a special mode, that is designed to be used both with forward rotation for tightening the bolts or nuts and reverse rotation for loosening the bolts or nuts.
Forward: bolt auto stop mode; the tool stops after applying a number of impacts to avoid fastening too tightly.
Reverse bolt removal mode; the tool stops automatically as soon as it has loosened the bolt/nut
The “ ” mode is intended for driving screws in wood. Using the “M” button: Press the “M” button directly without touching the trigger switch. The corresponding indicator light will illuminate to indicate the active mode. Press the “M” button briefly (less than 0.5 seconds) to cycle between “A” and“ ” modes. Each press changes one mode.

Reverse Rotation:

WARNING!
Do not change the working mode while the tool is running. A sudden change of torque may cause the loss of control causing possible injury or damage to the tool or workpiece

NOTE
The variety of wood density and metal material may affect the outcome. The user should select the appropriate mode based on the application.
NOTE
The LED indicator will turn off approximately 1 minute after the trigger switch is released.
NOTE
When the tool is next turned on, the working mode will revert to the previous setting.

Switching on the power tool (see Figure I)

To switch the power tool on: Press the trigger switch 2. The variable-speed trigger switch delivers higher speed with increased trigger pressure and lower speed with decreased trigger\ pressure.
To switch the power tool off: Release the trigger switch

LED light (see Figure J)

Press the “drive-control button ” and “M ” button simultaneously for 2 seconds
until the five indicator lights start flashing, indicating that the tool has entered the work light brightness adjustment mode. In the work light brightness adjustment mode, each time you press the trigger switch, the brightness will change to the next level and will cycle among the following six brightness levels.

Press the drive-control button or “M” Button to exit the work light brightness adjustment mode. If there is no operation for 5 seconds, the tool will automatically exit the brightness adjustment mode. The next time the tool is turned on and the memory function will remember and revert to the last work light brightness level. The light will turn off automatically approximately 10 seconds after the trigger\ switch is released.

Tighten and loosen nuts and bolts (see figure K)

To tighten nuts and bolts
Use the hex socket that matches the nut or bolt. Select a proper working mode depending on the type or size of the bolt and nut. Before starting your job, always perform a test operation to determine the proper fastening time for your bolt or nut. It is advisable to perform a trial run on scrap material to determine the best mode selection.

Set the direction preselector to switch 5 to the forward setting.

Hold the tool firmly and place the socket over the bolt or nut. Ensure that the full length of the bolt head or nut is fully engaged into the socket.
Depress the variable-speed trigger switch 2 to turn the impact wrench on. Start slowly, increasing the speed as the nut or bolt runs down. Set the nut or bolt snugly by slowing the tool to a stop. If this procedure is not followed, the tool will have a tendency to torque or twist in your hand when the nut or bolt seats.
Fasten the bolt or nut to the proper torque.
After fastening, always check the torque with a torque wrench. If the fasteners are too tight, reduce the impacting time.

NOTICE:

Hold the tool straight along the axis of the bolt or nut.
Excessive fastening torque may damage the bolt nut or socket. To loosen nuts and bolts
Use either mode 1, 2, 3, or “A” mode to lose nuts and bolts depending on the application. When working overhead or on car tires, to prevent the loosened fasteners from falling to the ground or into a tight space, it is recommended to use the “A” mode to do this job.
Set the direction preselector to switch 5 to the reverse setting.
Hold the tool firmly and place the socket over the bolt or nut. Ensure that the full length of the bolt head or nut is fully engaged in socket
Depress the variable-speed trigger switch 2 to turn the impact wrench on. Once the fastener is loose, the tool will stop running. This tool also allows you to continue to depress the trigger switch for removing the nut from the long bolt, if necessary
