OPERATION
CAUTION:
Always insert the battery cartridge all the way until it locks in place. If not, it may
accidentally fall out of the tool, causing injury to you or someone around you.
Hold the tool firmly with one hand on the grip and the other hand on the bottom of the battery
cartridge to control the twisting action.
Screw driving operation
CAUTION:
Adjust the adjusting ring to the proper torque level for your work.
Place the point of the driver bit in the screw head and apply pressure to the tool. Start the tool
slowly and then increase the speed gradually. Release the switch trigger as soon as the clutch
cuts in.
Make sure that the driver bit is inserted straight in the screw head, or the screw and/or bit may be
damaged.
NOTE:
When driving wood screws, predrill pilot holes to make driving easier and to prevent splitting of the
workpiece. See the chart.
