down before restarting.
④ Do not touch the belt and pulley while it is rotating. It is very dangerous.
⑤ Always use a protective cover, safety glasses or face shield anytime this device is in use.
⑥ Do not exceed the maximum recommended allowable speed. For your safety, use speeds
below the maximum allowable speed.
⑦ Do not apply heavy pressure to the belt or try to polish with the edge of the belt as the belt may
break and injure the operator.
CAUTION
① Do not drop or hit this Attachment, as shock can cause damage to the internal components.
② Be sure to clean the each part before replacing the belt. If polishing particles to the belt or
Attachment damage to the belt or Attachment can occur due to the loss of precision.
③ When cleaning a Attachment, stop the motor and remove dirt with a brush or a cloth. Do not
blow compressed air into the Attachment. Foreign particles or polishing debris may get into
the ball bearings.
④ Use for dry sanding only, the FINE BELT SANDER is not designed for wet sanding. Water
penetration into the bearings will cause damage to the bearings.

Afterwards, please check the content of Section 8 "TROUBLESHOOTING".
⑥ Always check if the belt and the each part are damaged before and after operating.
⑦ No lubrication is required because grease impregnated ball bearings are used.
⑧ After repair, initial operation, or long periods of non operational time, please use the following
break-in procedure. Start rotating slowly and over a short period of time, then increase the
speed gradually until reaching the maximum allowable speed.
⑨ 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.
Do not leave the belt sunder in direct sun light or extremely dry place. It causes deterioration.
