Class
A safety hazard could result in bodily injury or damage to the device if
WARNING
the safety instructions are not properly followed.
A hazard that could result in light or moderate bodily injury or damage
CAUTION
to the device if the safety instructions are not followed.
WARNING
① This product 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 touch the cutting tool while it is rotating. It is very dangerous
③ Always wear safety glasses, dust mask and use a protective cover.
CAUTION
① Do not drop or hit this Air Motor, as shock can cause damage to the internal components.
② Before use, carefully read " Air Line Kit Operation Manuals " regarding the correct connection,
operation and cautions when using the Air Line Kit.
③ When cleaning a Air Motor, stop the motor and remove dirt with a brush or a cloth. Do not
blow compressed air into the Air Motor. Foreign particles or cutting chips may get into the ball
bearings.
④ Stop operating immediately when abnormal rotation or any unusual vibrations are observed.
Afterwards, please check the content of section " 7. TROUBLESHOOTING ".
⑤ When using ROTUS Air Motor, Air Line Kit (AL - H1207F or any other equal characteristics) is
recommended for long lifetime.
⑥ Operating the Air Motor in low Lubricant conditions will cause low rotation speed, damage to
the internal components and shorter life of the Air Motor.
⑦ Be sure to drain moisture and condensation from the Air Line Kit ( lter regulator) regularly to
avoid moisture being carried to the Air Motor. This may cause damage to the Air Motor.
⑧ Do not use or storage the supply connection hose, supply and exhaust air / oil hose in a bent
state.
⑨ Prior to starting the day's work please check the following items: check the lter regulator
for proper sir pressure setting, check that lter is clean, and check that the lubricator has the
proper amount etc.. Afterward start rotating slowly and increase speed gradually.
⑩ 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 15 - 20minutes, increase
speed gradually until allowable maximum speed.
⑪ Do not disassemble, modify or attempt to repair the Air Motor. Additional damage will occur
to the internal components. Service must be performed by NSK NAKANISHI or an authorized
service center.
⑫ Securely connect the connection hose and supply air / oil hose to the motor Air Motor and Air
Line Kit to avoid accidental disconnection during use.
2 . FEATURE
① No heat is generated for long continuous use due to air driven operation.
② Air consumption is 75 N ℓ/min and can be used with air compressor of 1HP (7.5kW).
③ By mounting a silencer on the back exhaust air / oil hose, the quiet operation of air turbine is remarkably
improved.
④ Ring switch can be FWD./REV. turned to rotate the motor.
⑤ AIR MOTOR (IM - 301) has a " free joint mechanism " which prevents a hose from being twisted.
⑥ Clean air from tool can put away metal chips because Air Motor (IM - 300) has a chip air mechanism.
* IM - 300 is used with Attachment (IH - 300). IM - 300 can not be used with Attachments except IH - 300.

4 . CONNECTION OF THE AIR MOTOR TO THE ATTACHMENT
CAUTION
Make sure your hands and all interlocking parts of the attachment and Air Motor are clean before
connecting the Air Motor to the attachment. This is critical to prevent contaminants from entering
the Air Motor or attachment.
Align the thread on the front end of the Air Motor and the rear of the attachment, and turn the attachment clockwise.
If the drive shaft of the Air 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. Loosen the attachment from the
Air 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 Air Motor and attachment using the provided wrench. (Fig. 3)
