CONNECTION OF THE ATTACHMENT TO THE MOTOR
CAUTION
Make sure your hands and all interlocking parts of the Attachment and motor
are clean before connecting the motor to the Attachment. This is critical to
preventing contaminants from entering the motor or Attachment.
Align the thread on the front end of the
motor and the rear of the Attachment,
and turn the Attachment clockwise.
If the drive shaft of the motor does
not engage properly to the drive dog
on the Attachment, it may only turn
approximately two threads before
stopping. DO NOT FORCE THE
TOGETHER. Loosen the Attachment
from the motor, rotate the Attachment
shaft by hand then re-try. The drive shaft
and the drive dog must be fully engaged.
When fully engaged, secure the motor
and Attachment using the provided pin
wrench (K - 233) (Fig. 3).

CHANGING THE CUTTING TOOL
CAUTION
・ Do not open and close the collet without cutting tools.
・ Do not rotate the motor when replacing the cutting tools (when turning the
lever vertically toward a arrow in Fig. 4). This will cause damage to the motor
or the Attachment.
① Turning the lever vertically toward a arrow in Fig. 4 (counterclockwise) to loosen the
collet, the cutting tools can be replaced.
② Return the lever vertically to close the collet.
* If it is hard to remove the collet or the cutting tools, use the provided wrench.
When putting high torque by cutting tools with the large cutting tool diameter, or when
turning toward closing the collet, there is a case where the collet or cutting tools can
not be put off by hand. If so, align the nose's slit and spindle's wrench position, and
put a L shaped wrench to x the spindle. Set the provided wrench (5.1mm) to the
collet, turning the lever vertically. And turn the wrench counterclockwise to release the
collet or the cutting tools (Fig. 5).

REPLACING AND CLEANING OF THE COLLET
① Replacing of the collet
Turning the collet left to detach the collet,
turning the lever vertically (Fig. 6). Can
usually attach and detach the collet by
hand. If the attach or detach of the cutting
tool is dif cult, refer to " 8 CHANGING THE
CUTTING TOOL *If it is hard to remove the
collet or the cutting tools, use the provided
wrench " section.
② Cleaning of the collet
Release and clean the collet at least once a week not to loss it is precision. Coat oil
lightly on the collet before putting the collet back into Attachment.
③ Attachment and Adjustment of the collet
(1) Turning the lever vertically. And turning the collet clockwise by nger to the end to
attach, while clutching the test bur or the using cutting tools into the collet.
(2) And turn the collet about 1 / 5 counterclockwise to adjust the cutting tool to pull out
easily. In this case, about 0.1mm thinner of cutting tool can be used (Fig. 7).
* The clutching of collet can be adjusted according to the above. When loosing the
cutting tools, or not pulling it out, can be adjusted according to the above.
