①Do not drop or hit this Attachment, as shock can cause damage to the internal components.

②Be 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.

③When 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.

④Use 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.

⑤Stop operating immediately when abnormal rotation or any unusual vibrations are observed.

Afterwards, please check the content of Section 8 "TROUBLESHOOTING".

⑥Always check if the belt and the each part are damaged before and after operating.

⑦No lubrication is required because grease impregnated ball bearings are used.

⑧After 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.

⑨Do 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.

⑩Do not leave the belt sunder in direct sun light or extremely dry place. It causes deterioration.

WARNING

①This Attachment is designed for hand use. Never install this 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 " 3 - 1 Speci¿cations ").

③When sensing that the Attachment and motor are overheated during operation, reduce the

working force or the motor rotation speed, or stop the operation until the Attachment cools

down before restarting.

④Do not touch the belt and pulley while it is rotating. It is very dangerous.

⑤Always use a protective cover, safety glasses or face shield anytime this device is in use.

⑥Do not exceed the maximum recommended allowable speed. For your safety, use speeds

below the maximum allowable speed.

⑦Do 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

Make sure your hands and all interlocking parts of the Attachment and brushless motor are

clean before connecting the brushless motor to the Attachment. This is critical in preventing

contaminants from entering the brushless motor or Attachment.

Align the threads on the front end of the motor and the rear end 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 aprroximately two threads before stopping. DO NOT FORCE THEM TOGETHER. Turn

the Attachment back a few threads, rotate the Attachment by hand to engage the drive shaft and the

drive dog, and screw them together.
