The fastening torque can be adjusted in 21 levels by
turning the adjusting ring. Align the graduations with the
arrow on the tool body. You can get the minimum fas
-
tening torque at 1 and maximum torque at 21.
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 applica-
tion. The following shows the rough guide of the rela
-
tionship between the screw size and graduation.

Turn the sleeve counterclockwise to open the chuck
jaws. Place the driver bit/drill bit in the chuck as far
as it will go. Turn the sleeve clockwise to tighten the
chuck. To remove the driver bit/drill bit, turn the sleeve
counterclockwise.
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.

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.
Installing driver bit holder
Optional accessory

Driver bit
Fit the driver bit holder into the protrusion at the tool foot
on either right or left side and secure it with a screw.
When not using the driver bit, keep it in the driver bit
holders. Driver bits 45 mm-long can be kept there.
Installing side grip (auxiliary handle)
Optional accessory

Grip
Insert the side grip so that the protrusions on the arm fit in the
recesses on the tool. Then tighten the grip by turning clockwise.
Depending the operations, you can install the side grip
either right or left side of the tool.
OPERATION
CAUTION:
Always insert the battery cartridge
all the way until it locks in place.
If you can see the
red indicator on the upper side of the button, it is not
locked completely. Insert it fully until the red indicator
cannot be seen. If not, it may accidentally fall out of the
tool, causing injury to you or someone around you.
CAUTION:
When the speed comes down extremely,
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.

Screwdriving operation
CAUTION:
Adjust the adjusting ring to the
proper torque level for your work.
CAUTION:
Make sure that the driver bit is
inserted straight in the screw head, or the screw
and/or driver bit may be damaged.
First, turn the action mode changing ring so that the
arrow on the tool body points to the
marking.
Place the point of the driver bit in the screw head and apply pres
-
sure 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
and prevents splitting of the workpiece.
