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)

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.
