■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 Degree of Risk
WARNING
A safety hazard could result in bodily injury or damage to the device if
the safety instructions are not properly followed.
CAUTION
A hazard that could result in light or moderate bodily injury or damage
to the device if the safety instructions are not followed.
WARNING
①This 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.
②Do not touch the cutting tool while it is rotating. It is very dangerous
③Always wear safety glasses, dust mask and use a protective cover.
①Do not drop or hit this Air Motor, as shock can cause damage to the internal components.
②Before use, carefully read " Air Line Kit Operation Manuals " regarding the correct connection,
operation and cautions when using the Air Line Kit.
③When 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.
④Stop operating immediately when abnormal rotation or any unusual vibrations are observed.
Afterwards, please check the content of section " 7. TROUBLESHOOTING ".
⑤When using ROTUS Air Motor, Air Line Kit (AL - H1207F or any other equal characteristics) is
recommended for long lifetime.
⑥Operating the Air Motor in low Lubricant conditions will cause low rotation speed, damage to
the internal components and shorter life of the Air Motor.
⑦Be 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.
⑧Do not use or storage the supply connection hose, supply and exhaust air / oil hose in a bent
state.
⑨Prior 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.
⑩After 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.
⑪Do 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.
⑫Securely connect the connection hose and supply air / oil hose to the motor Air Motor and Air
Line Kit to avoid accidental disconnection during use.

(1) Take your foot off the Foot Control.
( When using a commercial Air Line Kit, stop the air supply with the ON / OFF Valve.)
(2) Remove all the pressure from the supply air / oil hose with the F / R Ring Switch.
WARNING
When stopping the Air Motor, release all the pressure from the supply air / oil hose by rotating the
Air Motor with the F / R Ring Switch. If the Ring Switch is not in the right position, the air cannot
be removed. Failure to do this may cause damage to the supply air / oil hose.
7. TROUBLESHOOTING
If a problem or concern occur, please check the following items prior to consulting your dealer.
Trouble Cause Inspection / Corrective Action
Air Motor does not
rotate or rotate
smoothly.
Air Àow does not reach the Air Motor. Check if input supply connection hose or air / oil
supply hose is broken, bent or disconnected.
Check connection of the input supply connection
and air / oil supply hoses.
Check the compressor power supply and the air
compressor output.
Check the Regulator and set to the correct air
pressure.
Check all connections input supply and air / oil
supply hose.
The spindles ball bearings have been
damaged. Replace the ball bearings. (Return to NAKANISHI dealer service.)
The motor has been damaged by for
no Lubricating Oil Replace the motor. (Return to NAKANISHI dealer service.)
Motor speed
decrease. The connection hose or air / oil supply hose have been damaged. Replace the input supply and or air / oil supply
hoses.
Poor connection of input supply or air
/ oil supply hose. Check all threaded joints and re-tighten if necissary.
Low air pressure. Check the Compressor, Air Circuit, and Regulator.
Low Lubricating Oil. Check lubricator for proper lubricant level. Set the
Oil Drip Rate from 1 to 3 drops /min.
* If using the " AL - 0306 "Air Line Kit, adjust the
proper Oil Drip Rate to 30 - 40 drops / min.
No Lubricating Oil. Clean inside of the motor use the Lubricating Oil.
Removing the Filter Joint from Air Line Kit, supply
a small amount of Lubricating Oil directly into
the Filter Joint. Afterwards, supply air pressure
and rotate the Air Motor. Flush dirt in the motor
and repeatedly do this work about three times.
When the improvement is not seen, return to
NAKANISHI dealer service.
Water, dirt and debris are collected in
the Filter Regulator. Drain water, dirt and debris from the Filter Regulator Bowl.
Water in Lubricating Oil reservoir. Drain water from Lubricating Oil reservoir and
replace with clean Lubricating Oil.
Unequal motor
rotation. Excessive Oil Drip Rate Àooding the bearings. Oil drip rate exceeds the recommended amount. Adjust for the proper Oil Drip Rate.
Over ¿lled lubricator.
(Air Line Kit " AL - 0306 " only.) Drain the Lubricating Oil from Reservoir to meet indicated levels. Excess lubricant will Àood
spindle.
Overheating during
rotation. Cutting debris has contaminated the ball bearings, and the ball bearings
are damaged.
Replace the ball bearings.
(Return to NAKANISHI dealer service.)
Abnormal vibration
or noise during
rotation.
Cutting debris has contaminated the
ball bearing.
The spindles ball bearings have been
damaged.
8. DISPOSAL OF THE AIR MOTOR
When disposal of an Air Motor is necessary, follow the instructions from your local government agency for proper
disposal of industrial components.
5 - 4 Operation
CAUTIONS IN USING AIR LINE KIT
・ When connecting the Compressor and Air Line KIt, recommended install the ¿lter or air dryer
to between Compressor and Air Line Kit in order to supply clean dry air to the Air Motor. Using
compressed air containing excessive moisture could result in malfunction or failure of the
Air Motor. If excessive moisture or condensation are found in Filter Regulator Bowl, it will be
necessary to install a dryer and larger Filter on the Primary Joint side of the Air Line Kit to prevent
and remove excessive moisture.
・ Connect the input air supply connection hose and supply air / oil hose securely to avoid
accidental disconnection during use. Input air pressure should never exceed 1.0MPa (145psi). Air
pressure exceeding 1.0MPa (145psi) may cause the supply connection hose and or air / oil hose
supply to rupture.
・ Make sure operation air pressure is less than 1.0MPa (145psi) before connecting the input supply
connection hose and air / oil supply hose. If operation air pressure is exceeds 1.0MPa (145psi),
injury to the operator may occur by accidental disconnection before or during use.
・ Before use, carefully read " Air Line Kit Operation Manuals " regarding the correct connection,
operation and cautions when using the Air Line Kit.
③Insert a tube of nozzle into a pipe.
