The fastening torque can be adjusted in 20 steps by
turning the adjusting ring so that its graduations are
aligned with the pointer on the tool body. The fastening
torque is minimum when the number 1 is aligned with
the pointer, and maximum when the
marking is
aligned with the pointer.
The clutch will slip at various torque levels when set at
the number 1 to 19. The clutch is designed not to slip at
the
marking.
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:
•
Do not operate the tool with the adjusting ring set
between the number 19 and the
marking. The
tool may be damaged.
ASSEMBLY
CAUTION:
•
Always be sure that the tool is switched off and the
battery cartridge is removed before carrying out
any work on the tool.

Hold the ring and turn the sleeve counterclockwise to
open the chuck jaws. Place the bit in the chuck as far as
it will go. Hold the ring firmly and turn the sleeve
clockwise to tighten the chuck.
To remove the bit, hold the ring and turn the sleeve
counterclockwise.
OPERATION
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 switch 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.
•
When driving wood screws, predrill pilot holes to
make driving easier and to prevent splitting of the
workpiece. See the chart.

NOTE:
•
If the tool is operated continuously until the battery
cartridge has discharged, allow the tool to rest for
15 minutes before proceeding with a fresh battery.
Drilling operation
First, turn the adjusting ring so that the pointer points to
the
marking. Then proceed as follows.
Drilling in wood
When drilling in wood, the best results are obtained with
wood drills equipped with a guide screw. The guide screw
makes drilling easier by pulling the bit into the workpiece.
Drilling in metal
To prevent the bit from slipping when starting a hole,
make an indentation with a center-punch and hammer at
the point to be drilled. Place the point of the bit in the
indentation and start drilling.
Use a cutting lubricant when drilling metals. The
