(120V) This tool is intended for use on a circuit that has an outlet that looks like the one illustrated in Sketch A in Figure
(below). The tool has a grounding plug that looks like the plug illustrated in Sketch A in figure (below). A temporary
adapter, which looks like the adapter illustrated in Sketches B and C, may be used to connect this plug to a 2-pole
receptacle as shown in Sketch B if a properly grounded outlet is not available. The temporary adapter should be used
only until a properly grounded outlet can be installed by a qualified electrician. The green-colored rigid ear, Iug, and the
like, extending from the adapter must be connected to a permanent ground such as a properly grounded outlet box.
Note : Adopter (Figure B) not for use in Canada.

USE PROPER EXTENSION CORD Make sure your extension cord is in good condition. When using an extension cord, be
sure to use one heavy enough to carry the current your product will draw. An undersized cord will cause a drop in line
voltage resulting in loss of power and overheating. Table (below) shows the correct size to use depending on cord length
and nameplate ampere rating. If in doubt, use the next heavier gauge. The smaller the gauge number, the heavier the cord.

Only the applicable parts ot the Table need to be included. For instance, a 120volt product need
include the 240-volt heading.
B. OTHER WARNING INSTRUCTIONS
q
Do not exceed the " Maximum Allowable Motor Rotation Speed " (Refer to "S Specifications ").
w
When 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.
e
Always wear cap, gloves, Iong sleeve shirt, safety glasses and hearing protection anytime this device is in use.
r
Do Not Touch the attachment or motor when the system is operating.
t
This is a high torque system and burs can grab on the workpiece. Always wear gloves to prevent injury anytime you
are using this system. Grinding and deburring produces lots of chips and other dust, keep work are clean and put
away items that can be damaged by chips, sand or other contaminants.
y
Check that the collet has been securely tightened prior to each use. Burs can fly loose from the chuck and injure operator or anyone nearby.
u
Avoid applying heavy hand pressure during operation; Iet the tool do the work. Heavy force can bend or break bur shanks
which can injure operator or anyone nearby. If the motor slows down noticeably during operation, you are applying too
much pressure; this type of operation will shorten motor, attachment and tool life and dramatically reduce productivity.
i
Do not use bent, broken, cracked or damaged tools, or tools with excessive runout. When using tools with a very
large head to shank diameter ratio sudden speed increases can bend or break shank. When using a new or large
tool, rotate it at low speed and increase speed gradually for safety.
o
Always operate tools within the tool manufacturer's recommended speed limits. Use of a tool outside of the manufacturer's
recommended speed limits could cause damage to the spindle and injury to the operator. A foot pedal can be used to vary speed.
!0
Do not hit or drop the attachment or motor because the shock can damage internal components. Always set the
control unit on a flat, hard, steady surface.
!1
If the control unit, motor or attachment emit smoke, burning plastic odor or any other unusual odor, please
immediately turn off the power switch, disconnect the power cord and send to NAKANISHI for service.
!2
Never attempt to operate this system, touch power cord or switch unit on or off, etc. with wet hands. Failure to
adhere to this warning can result in severe electric shock.
!3
Use only tools with shank diameter tolerance similar to the chuck I.D. tolerance.
!4
The motor has a nakanishi Smart switch which provides a click sensation. Be careful when operating the switch, because the motor is on/off.
!5
Do not exceed 13mm overhang for mounted grindstones. In case overhang must exceed 13mm reduce the motor
speed in accordance with Table 1 .
!6
Do not disassemble, modify or attempt to repair the control unit, motor, motor cord, attachment and foot pedal. Additional
damage internal components. Service must be performed by NSK NAKANISHI or an authorized service center.
