Operation - Makita DTW280 Instruction Manual

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.
Selecting correct socket
Always use the correct size socket for bolts and nuts.
An incorrect size socket will result in inaccurate and
inconsistent fastening torque and/or damage to the bolt
or nut.
Installing or removing socket
For socket without O-ring and pin
Fig.8
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
Fig.9
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 procedures in reverse.
Hook
Fig.10
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.

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.
Fig.11
Hold the tool firmly and place the socket over the bolt or
nut. Turn the tool on and fasten for the proper fastening
time.
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.
