Procedure 1 (Fig. 9)
For tool with normal sleeve
To install the bit, pull the sleeve in the direction of the
arrow and insert the bit into the sleeve as far as it will go.
Then release the sleeve to secure the bit.
For tool with one-touch type sleeve
To install the bit, insert the bit into the sleeve as far as it
will go.
Procedure 2 (Fig. 10)
In addition to the procedure (1) above, insert the bit-
piece into the sleeve with its pointed end facing in.
To remove the bit, pull the sleeve in the direction of the
arrow and pull the bit out.
NOTE:
• If the bit is not inserted deep enough into the sleeve,
the sleeve will not return to its original position and the
bit will not be secured. In this case, try re-inserting the
bit according to the instructions above.
• When it is difficult to insert the bit, pull the sleeve and
insert it into the sleeve as far as it will go.
• After inserting the bit, make sure that it is firmly
secured. If it comes out, do not use it.
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
housing on either side and then secure it with a screw. To
remove, loosen the screw and then take it out.
OPERATION (Fig. 12 & 13)
CAUTION:
• Never obstruct the air vents on the side of the tool for
cooling down oil unit and motor during operation.
Failure to do so may cause the tool excessive heat and
damage.
The proper fastening torque may differ depending upon
the kind or size of the screw/bolt, the material of the
workpiece to be fastened, etc. The relation between
fastening torque and fastening time is shown in the
figures. (Fig. 14 & 15)
