You can change the impact in three steps: hard, medium
and soft mode.
This allows a tightening suitable to the work.
Every time the button
blows changes in three steps.
For approximately one minute after releasing the switch
trigger, the impact force can be changed.
ASSEMBLY
CAUTION:
• Always be sure that the tool is switched off and the bat-
tery cartridge is removed before carrying out any work
on the tool.
Selecting correct socket
Always use the correct size socket for bolts and nuts. An
incorrect size socket will result in inaccurate and incon-
sistent fastening torque and/or damage to the bolt or nut.
Installing or removing socket (Fig. 9 & 10)
For socket without O-ring and pin
Align the hole in the side of the socket with the detent pin
on the square drive and push the socket onto the square
drive until it locks into place. Tap it lightly if required.
To remove the socket, simply pull it off.
For socket with O-ring and pin
Move the O-ring out of the groove in the socket and
remove the pin from the socket. Fit the socket onto the
square drive so that the hole in the socket is aligned with
the hole in the square drive. Insert the pin through the
hole in the socket and square drive. Then return the O-
ring to the original position in the socket groove to retain
the pin. To remove the socket, follow the installation pro-
cedures in reverse.

Hook (Fig. 11)
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 hous-
ing on either side and then secure it with a screw. To
remove, loosen the screw and then take it out.
OPERATION
CAUTION:
• Always insert the battery cartridge all the way until it
locks in place. If you can see the red part on the upper
side of the button, it is not locked completely. Insert it
fully until the red part cannot be seen. If not, it may
accidentally fall out of the tool, causing injury to you or
someone around you.
Hold the tool firmly and place the socket over the bolt or
nut. Turn the tool on and fasten for the proper fastening
time. (Fig. 12)
The proper fastening torque may differ depending upon
the kind or size of the bolt, the material of the workpiece
to be fastened, etc. The relation between fastening
torque and fastening time is shown in the figures.

Model DTW281 (Fig. 15 & 16)
NOTE:
• Hold the tool pointed straight at the bolt or nut.
• Excessive fastening torque may damage the bolt/nut or
socket. Before starting your job, always perform a test
operation to determine the proper fastening time for
your bolt or nut.
• If the tool is operated continuously until the battery car-
tridge has discharged, allow the tool to rest for 15 min-
utes before proceeding with a fresh battery cartridge.
The fastening torque is affected by a wide variety of fac-
tors including the following. After fastening, always check
the torque with a torque wrench.
