Adjusting the fastening torque
► Fig.7: 1. Adjusting ring 2. Graduation 3. Arrow
The fastening torque can be adjusted in 22 levels by turning the adjusting ring. Align the graduations with the arrow
on the tool body. You can get the minimum fastening torque at 1 and maximum torque at
The clutch will slip at various torque levels when set at the number 1 to 21. The clutch does not work 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.
The following shows the rough guide of the relationship between the screw size and graduation.

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.
Installing or removing driver bit/
drill bit

Installing hook
CAUTION:
When installing the hook, always
secure it with the screw firmly. If not, the hook
may come off from the tool and result in the personal
injury.
► Fig.9: 1. Groove 2. Hook 3. Screw
The hook is convenient for temporarily hanging the tool.
This can be installed on either side of the tool. To install
the hook, insert it into a groove in the tool housing on
either side and then secure it with a screw. To remove,
loosen the screw and then take it out.

CAUTION:
reduce the load or stop the tool to avoid the tool damage.
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.

inserted straight in the screw head, or the screw
and/or driver bit may be damaged.
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: When driving wood screw, pre-drill a pilot hole
2/3 the diameter of the screw. It makes driving easier
