1. CAUTIONS FOR HANDLING AND OPERATION
■ 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.
Class
A safety hazard could result in bodily injury or damage to the
WARNING
device if the safety instructions are not properly followed.
A hazard that could result in light or moderate bodily injury or
CAUTION
damage to the device if the safety instructions are not followed.
WARNING
① The Attachment is designed for hand use. Never install the Attachment or any hand tool on a
machine such as a special purpose machine, NC lathe or mill.
② Do not exceed the " Maximum Allowable Motor Rotation Speed " (Refer to " 6 - 1 Speci cations ").
③ When sensing that the Attachment and motor / reducer, are overheated during operation, reduce
the working force or the motor rotation speed, or stop the operation until the Attachment cools
down before restarting.
④ Do not touch the cutting tool while it is rotating. It is very dangerous.
⑤ Wear safety glasses, dust mask and use a protective cover around the Attachment whenever the
Attachment is rotating.
⑥ When 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.
⑦ Do not use grindstones with an outside diameter over
⑧ Do 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.
⑨ Do 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.
⑩ Always 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.
⑪ Do not apply excessive force. This may cause cutting tool slippage, cutting tool damage, injury to
the operator, loss of concentricity and precision.

* N = Max. Operating Speed with 13mm overhang.
CAUTION
① KC - 300 and EKC - 300 are rotates the opposite direction of motor runs so that be aware of this
fact at the time of use.
② Do not drop or hit this Attachment, as shock can damage to the internal components.
③ Be 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.
④ When cleaning an Attachment, stop the Attachment and remove debris with a soft brush or a cloth.
Do not blow air into the Attachment with compressed air as foreign particles or cutting debris may
get into the ball bearing.
⑤ Always clean the cutting tool shank before installing the cutting tool in the spindle.
⑥ When 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.
⑦ Select suitable products or cutting tools for each application. Do not exceed the capabilities of the
Attachment or cutting tools.
⑧ Keep everything in order not to place the rag which could be caught near the Attachment.
⑨ Stop operating immediately when abnormal rotation or unusual vibrations are observed.
Immediately, please check the content of section " 11. TROUBLESHOOTING ".
⑩ Always check if the cutting tool and collet are damaged before and after operating.
⑪ If the collet show signs of wear or damage, replace it before a malfunction or additional damage
occurs.
⑫ No lubrication is required because grease impregnated ball bearings are used.
⑬ After 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 Maximum Allowable Motor Rotation Speed.
⑭ Do 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.
⑮ When using this Attachment for mass production, please consider the purchase of an additional
Attachment to be used as a back-up in case of emergency.
