CAUTIONS FOR HANDLING AND OPERATION
Class Degree of Risk
WARNING
A safety hazard could result in bodily injury or
damage to the device if the safety instructions are
not properly followed.
CAUTION
A hazard that could result in light or moderate
bodily injury or damage to the device if the safety
instructions are not followed.
1.
■Read these warnings and cautions carefully and only use in the manner intended.
■These warnings and cautions are intended to avoid potential hazards that could result
in personal injury to the operator or damage to the device. These are classi¿ed as
follows in accordance with the seriousness of the risk.
①This Attachment is designed for hand use. Never install this Attachment or
any hand cutting tool on a machine such as a special purpose machine, NC
lathe or mill.
②Do not touch the cutting tool while it is rotating. It is very dangerous.
③Wear safety glasses, dust mask, and use a protective cover around the
Attachment whenever the Attachment is rotating.
④When installing a cutting tool, tighten the collet correctly and check again
the collet before use. Do not over-tighten the collet. This may cause
damage to the spindle.
⑤Do not use grindstones with an outside diameter over ₥15mm.
⑥Do not exceed 13mm of overhang for mounted grindstones as shown
in Fig. 1. If the overhang must exceed 13mm, reduce the motor speed in
accordance with Table 1.
⑦Do not use bent, broken, chipped, out of round or sub-standard cutting
tools as they may cause shatter or explode.
The cutting tool with cracked, bended may cause some injury to operator.
When using a new cutting tool, rotate it in a low speed and increase speed
gradually for safety.
⑧Always operate cutting tools within the cutting tool manufacturer's
recommended speed limits. Use of a cutting tool higher than the
manufacturer's recommended speed limits could cause damage to the
spindle and injury to the operator.
⑨Do not apply excessive force. This may cause cutting tool slippage, cutting
tool damage, injury to the operator, loss of concentricity and precision.

①Do not drop or hit this Attachment, as shock can damage to the internal
components.
②Be sure to clean the collet, the spindle taper and threads before replacing
the cutting tool. If ground particles or metal chips stick to the inside of
spindle or the collet, damage to the collet or spindle can occur due to the
loss of precision.
③When cleaning an Attachment, stop the motor and remove dirt with a
brush or a cloth. Do not blow compressed air into the Attachment. Foreign
particles or cutting chips may get into the ball bearings.
④Always clean the cutting tool shank before installing the cutting tool in the
spindle.
⑤When sizing the correct collet size to the cutting tool shank diameter, a
tolerance of +0 〜
-
0.01mm is strongly recommended.
A cutting tool shank within the +0 〜
-
0.1mm range is mountable, however,
this may cause poor concentricity and or insuf¿cient cutting tool shank
gripping force.
⑥Select suitable products or cutting tools for each application. Do not
exceed the capabilities of the Attachment or cutting tools.
⑦Keep everything in order not to place the rag which could be caught near
the hand tool.
CAUTION
⑧Stop operating immediately when abnormal rotation or unusual vibrations
are observed. Immediately, please check the content of section
" 10. TROUBLESHOOTING ".
⑨ Always check if the cutting tool, collet is damaged before and after operating.
⑩If the collet show signs of wear or damage, replace it before a malfunction
or additional damage occurs.
⑪No lubrication is required because grease impregnated ball bearings are
used.
⑫After installation, repair, initial operation, or long periods of non operation,
please carry out break-in as follow. Start rotating slowly and over a short
period of 5 - 10 minutes, increase speed gradually until allowable maximum
speed.
⑬Do not disassemble, modify or attempt to repair the Attachment. Additional
damage will occur to the internal components. Service must be performed
by NSK NAKANISHI or an authorized service center.

CONNECTION OF THE ATTACHMENT TO THE MOTOR7.
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.
CAUTION
Tighten
Transmission Clutch
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 theAttachment
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 TOOL8.
・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.
CAUTION
①Turning the lever vertically toward a arrow in Fig. 4 (counterclockwise) to loosen the
collet, the cutting tools can be replaced.
②Return 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).
