② Do not touch the cutting tool while it is rotating. It is very dangerous.
③ Wear safety glasses, dust mask, and use a protective cover around the
Attachment whenever the Attachment is rotating.
④ 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.
⑤ Do not use grindstones with an outside diameter over
⑥ 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.
⑦ 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.
⑧ 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.
⑨ Do not apply excessive force. This may cause cutting tool slippage, cutting

CAUTION
① Do not drop or hit this Attachment, as shock can damage to the internal
components.
② 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.
③ When 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.
④ Always clean the cutting tool shank before installing the cutting tool in the
spindle.
⑤ 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.
⑥ Select suitable products or cutting tools for each application. Do not
exceed the capabilities of the Attachment or cutting tools.
⑦ Keep everything in order not to place the rag which could be caught near
the hand tool.
