OPERATION MANUAL
Thank you for purchasing Straight Attachment " IG - 400 ". This Attachment
is designed for strong retention and high precision performance. The Emax
EVolution Motor or the ROTUS Air Motor are required to drive this Attach-
ment. Read this and all the associated component Operation Manuals care-
fully before use. Always keep this Operation Manual in a place where a user
can referred to for reference at any time.
1 . CAUTIONS FOR HANDLING AND OPERATION
■ Read these cautions carefully and only use in the manner intended.
■ These warnings and cautions are intended to avoid potential hazards that
could result in personal injury or damage to the device. These are classi-
fied as follows in accordance with the seriousness of the risk.
Class
A safety hazard could result in bodily injury or damage
WARNING to the device if the safety instructions are not properly
followed.
A hazard that could result in light or moderate bodily
CAUTION injury or damage to the device if the safety instructions
are not followed.
WARNING
The 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.
Do not touch the cutting tool while it is rotating. It is very dangerous.
Always wear safety glasses, dust mask and hearing protection.
When installing a cutting tool, tighten the collet chuck correctly
and recheck the collet chuck and chuck nut before use. Do not
over tighten the collet chuck. This may cause damage to the
spindle.
Do not use grindstones with an outside diameter over
Do not exceed 13 mm of overhang for mounted grindstones as
shown in Fig. 1 .
If the overhang must exceed 13 mm, reduce the motor speed in
accordance with Table 1 .
Do not use bent, broken, chipped, out of round or sub-standard
tools, as they can shatter or explode.
A sudden speed increase when using a large cutting tool can
cause the shank to bend or break. When using a new tool or a
large tool, rotate it in a low speed and increase speed gradually
for safety.
Always operate cutting tools within the cutting tool manufacturer's
recommended speed limits. Use of a cutting tool higher than the
manufacturer's recommended speed limits could cause damage
to the spindle and injury to the operator.
Do not apply excessive force. This may cause tool slippage, tool
damage, injury to the operator, loss of concentricity and precision.

CAUTION
Do not drop or hit this Attachment, as shock can cause damage
to the internal components.
Be sure to clean the collet chuck, chuck nut and the spindle taper
and threads before replacing the cutting tool. If ground particles or
metal chips stick to the inside of spindle or the collet chuck, damage
to the collet chuck or spindle can occur due to the loss of precision.
When cleaning a spindle, stop the motor and remove dirt with a brush
or a cloth. Do not blow compressed air into the Attachment. Foreign
particles or cutting chips may get into the ball bearings.
Always clean the tool shank before installing the tool in the spindle.
Use only tools with shank diameters within the tolerance of the selected
collet chuck.
Select suitable products or tools for each application. Do not exceed
the capabilities of the Attachment or cutting tools.

CAUTION
Stop operating immediately when abnormal rotation or any unusual
vibrations are observed. Afterwards, please check the content of
Section 7 "TROUBLESHOOTING".
Always check if the tool, collet chuck is damaged before and after
operating.
If the collet chuck show signs of wear or damage, replace it
before a malfunction or additional damage occurs.
No lubrication is required because grease impregnated ball
bearings are used.
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.
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.
