OPERATION
WARNING!
To reduce the risk of injury, wear safety goggles or glasses with side shields.
Selecting Speed (Fig. 4)
The speed selector is on top of the motor housing. Allow the tool to come to a complete stop before changing speeds. See “Applications” for rec- ommended speeds under various conditions.
Using Clutch (Fig. 3)
This tool has an adjustable clutch for driving different types of screws into different materials. When properly adjusted, the clutch will slip at a preset torque to prevent driving the screw too deep and to prevent damage to the screw or tool. Refer to the table below to select the correct position for the type of material and screw size you are using.
To adjust the clutch, turn the clutch adjusting ring to one of the nineteen positions shown on the adjusting ring.

Low High
1.For Low speed (up to 360 RPM), push the speed selector forward.
2.For High speed (up to 1,100 RPM), push the speed selector back.
Starting, Stopping & Controlling Speed
To start the tool, pull the trigger.
To stop the tool, release the trigger and an electric brake stops the tool instantly.
All models feature variable speed control. To vary the speed, simply in- crease or decrease pressure on the trigger. The further the trigger is pulled, the greater the speed.
Using Control Switch (Fig. 5)
The control switch may be set to three positions: forward, reverse and lock. Due to a lockout mechanism, the control switch can only be ad- justed when the ON/OFF switch is not depressed. Always allow the motor to come to a complete stop before using the control switch.
