The fastenina toraue can be adiusted in six |
|
|
stages by turning the adjusting ring so that |
|
|
the pointer on the adjusting ring points to |
|
|
anumber on the tool body. The fastening torque is minimum when the pointer points to the number 1 and maximum when it points to the
Before actual operation, drive a trial screw into your material or a piece of duplicate material to determine which torque level is required for a particular application.
NOTE :
The adjusting ring cannot be locked with the pointer positioned
Screwdriving operation
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 trigger as soon as the clutch cuts in.
NOTE :
Make sure that the driver bit is inserted straight in the screw head, or the screw and/or bit may be damaged.
s When driving wood screws, predrill pilot holes to make driving easier and to pre- vent splitting of the workpiece. See the chart.
