Nakanishi LUSTER LS-100 User manual

General Warnings for All Vibrating Equipment
①Repeated or long-term exposure to excessive vibration may cause temporary or permanent
physical injury, particularly to the hands, arms and shoulders.
②It is strongly recommended that anyone using vibrating equipment, such as power hand tools,
¿rst be physically examined by a doctor and then have regular medical check-ups to make sure
the user doesn't 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.
③If you feel any medical or physical symptoms related to vibration (such as tingling, numbness and
white or blue ¿ngers), report the situation to your employer and seek medical advice as soon as
possible.
④Avoid smoking while using vibrating equipment, as nicotine reduces the blood supply to the hands
and ¿ngers.
⑤Suitable gloves should be worn to reduce the vibration effects on the user.
⑥Tools with the lowest vibration should be used when there is a choice between different processes.
⑦Work schedules should be arranged to include vibration-free periods throughout each day.
Additional Warnings for the Safe Use of LUSTER (LS-100/ELS-100)
①LUSTER should only be used after reading and understanding the Operation Manual.
②Grip LUSTER as lightly as possible (while still keeping safe control of it).
Let LUSTER do the work.
③To ensure your safety, LUSTER should be
maintained as explained in this Operation Manual.
④Do not use LUSTER at vibration levels of
2.5 m/s2and higher. Select the combination
of motor rotation speed and stroke so that the vibration
level stays in the shaded area as shown on the
chart lower right (Fig. 1)
⑤Do not use LUSTER with vibration at 2.5 m/s2or
higher each day for an extended period of time.
⑥If any abnormal vibration occurs stop using
LUSTER immediately and return to NAKANISHI
for service.
CAUTION ON HANDLING
1. CAUTIONS FOR HANDLING AND OPERATION
■Read these cautions carefully and only use in the manner intended.
■Warnings and cautions are intended to avoid potential hazards that could result in personal injury or damage to
the device. These are classi¿ed as follows in accordance with the seriousness of the risk.
①This 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.
②Use a protective cover, glasses and/or facemask for your safety during rotation.
③Do not touch bur-holder, tool etc, while they are in the reciprocating motion.
④Do not drop or hit LUSTER, because the shock could damage the internal components.
⑤Check if the tool/¿le has been mounted ¿rmly, before operation.
⑥Do not force the tool/¿le to overload, or it may be damaged.
⑦Do not so overload LUSTER that could function the protective circuit.
⑧Be sure to keep LUSTER/motor away from water. It could cause an electric shock to the operator.
⑨Do not lubricate LUSTER/motor and any bearings in the system, as grease¿lled bearings are used.
⑩After repair, initial operation, or long periods of non operational time, please use the following
break-in procedure. Adjust stroke length is 1mm. Start rotating slowly and over a short period of
time, then increase the speed gradually until reaching the maximum allowable speed.
