WARNING!
OPERATION
For driving small screws.
For driving screws into soft materials
such as wood veneers, etc.
For terminal screws on electrical
equipment, etc.
For driving screws into hardwood.
For drilling and powerful screwdriving.
The torque specifications shown here are approximate values obtained
with a fully charged battery pack.
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.
NOTE:
Because the above settings are only a guide, use a piece of scrap
material to test the different clutch positions before driving screws into
the workpiece.
