Nakanishi NLS-110 User manual

1
Thank you for purchasing the LUSTER NLS-110. It is designed for polishing, lapping and
honing after metal mold machining. Please read this operation manual carefully before use.
qUse a protective cover, glasses and/or facemask for your safety during usage.
wDo not touch the bur-holder, tool, etc. while it is in a reciprocating motion.
e
Do not drop or hit LUSTER, because the shock could damage the internal components.
rCheck if the tool/file has been mounted firmly, before operation.
tDo not force the tool/file to overload, or the
LUSTER may be damaged.
yOverloading LUSTER could activate the protective circuit.
u
Be sure to keep LUSTER/motor away from water. It could cause an electric shock to the operator.
i Do not lubricate LUSTER/motor or any bearings in the system, as grease-filled bearings are used.
oThe LUSTER NLS-110 is powered by the Emax EVOlution control unit NE249.
(Never connect to Emax control unit NE129)

qRepeated or long-term exposure to excessive vibration may cause temporary or
permanent physical injury, particularly to the hands, arms and shoulders.
wIt is strongly recommended that anyone using vibrating equipment, such as
power hand tools, first be physically examined by a doctor and then have regular
medical check-ups to make sure the user does not have any medical problems
that are being caused or worsened by using vibrating equipment.People who
have impaired blood circulation to the hand, past hand injuries, nervous system
disorders and Raynaud’s disease should not use vibrating equipment.
e
If you feel any medical or physical symptoms related to vibration (such as tingling,
numbness and white or blue fingers), report the situation to your employer and
seek medical advice as soon as possible.
rAvoid smoking while using vibrating equipment, as nicotine reduces the blood
supply to the hands and fingers.
tSuitable gloves should be worn to reduce the vibration effects on the user.
yTools with the lowest vibration should be used when there is a choice between
different processes.
uWork schedules should be arranged to include vibration-free periods throughout
each day.
q
LUSTER should only be used after reading and understanding the Operation Manual.
wGrip LUSTER as lightly as possible (while still keeping safe control of it).
Let LUSTER do the work.
eTo ensure your safety, LUSTER should be maintained as explained in this
Operation Manual.
rDo not use LUSTER at vibration levels of 2.5 m/s2and higher.Select the
combination of motor speed and stroke so that the vibration level stays in the
shaded area as shown on the chart lower right.
tDo not use LUSTER with vibration at 2.5 m/s2or higher each day for an extended
period of time.
y
If any abnormal vibration occurs stop using LUSTER
immediately and return to NAKANISHI for service.
u Do not exceed the motor speed of 30,000min
-1
(rpm) to
prevent trouble or damage.
i Remove the plug from the control unit when adjusting
the stroke length for safety reasons.
