§ 1. Introduction

This manual describes the mechanical assembly, adjustment, and maintenance of Fujikura’s FSM-40S

fusion splicer. When maintaining the FSM-40S, it is important to locate the exact problem and make

the necessary repairs properly. This manual will provide processes to repair the FSM-40S in a safe,

concise, and easy to follow manner for a qualified technician.

§ 2. Notes to users

§ 2.1. Warning and Cautions for Maintenance

This maintenance manual also includes safety requirements.

• Read this manual carefully before performing any maintenance procedure to the splicer.

• Keep this manual in a safe place.

Fujikura Ltd. accepts no responsibility for personal injury or physical loss including equipment damage

resulting from improper use or modification.

This maintenance manual indicates warnings and cautions by using alert symbols. It is important to understand

what it means.

WARNING

There is a possibility of personal death or serious injury resulting from improper use

by ignoring this indication.

CAUTION

There is a possibility of personal injury or physical loss resulting from improper use by

ignoring this indication.

Symbol means “Pay Attention.”

The left symbol indicates “Pay attention to explosion.”

Symbol means “Must not do.”

The left symbol indicates “You must not disassemble.”

Symbol means “Must do.”

The left symbol indicates “You must disconnect the AC power cord from the wall socket

or the appliance inlet.”

Alert Symbol

Example of Alert Symbol

Page 6

WARNING

The appliance inlet is used to disconnect the power cord when you disassemble the splicer.

Check to insert the all connector correctly before packaging.

Never maintain the splicer in an environment where flammable liquid or vapor exists. Extremely

dangerous fire and explosion could result from the splicer’s electrical arc in such an environment.

Do not disassemble or modify AC adapter and battery pack. In particular, do not remove or bypass

any electrical or mechanical device (e.g. a fuse or safety switch) incorporated into the design and

manufacturing of this equipment.

Check the connector to insert correctly before discharging.

During arc discharge, the electrodes generate high voltage and high temperature, and it causes

personal injury. Do not touch the electrodes during the maintain (though arc discharge stops when

the wind protector is opened). Turn the splicer power off, and disconnect the AC power cord (or

remove the battery pack) when replacing the electrodes.

This equipment is designed for splicing optical glass fiber for telecommunication. Do not attempt to

splice any materials other than the optical glass fibers.

Never use a canned type air cleaner to remove dust, or to clean the splicer. The electrical arc may

ignite any remaining gas mixture.

Safety glass should always be worn during the fiber preparation and the splicing process. A glass

fiber fragment can be extremely dangerous if it comes into contact with the eye, skin, or is ingested.

Use only specified power supply unit and proper AC power source.

• Only the AC adapter / battery charger (ADC-07) or the battery pack (BTR-04) can be used for

supplying power to the splicer.

• Proper AC power source to the ADC-07 is AC100-240V, 50-60Hz. Check the AC power source

before use. Improper AC power source out of the range can cause personal injury, emitting smoke

or equipment damage.

• Abnormal high AC output voltage or frequency from an AC generator is a common fault.

Measure the output AC voltage by a circuit tester before connecting the AC power cord.

Improper high voltage or frequency from generator causes personal injury, emitting smoke or

equipment damage.

Use only specified AC power cord. Do not put a heavy object on the power cord. Also, do not pull,

heat up or modify the power cord. Using an improper cord or a damaged cord can result in a fire,

emitting smoke, equipment damage or personal injury.

Page 7

WARNING

Connect the AC power cord properly to the appliance inlet and wall socket. When inserting the AC

plug, confirm no dust or dirt on terminals, and insert it to the end. Incomplete connection can cause a

fire, emitting smoke or personal injury.

Connect the AC adapter / battery charger to electrical ground when using it. It is possible to connect

through a third pin of AC plug. No connection to electrical ground can cause personal injury.

Use only the specified battery charger (ADC-07) to recharge the battery pack (BTR-04) with a

battery charger cord (DCC-08). Personal injury or equipment damage can result from using not

specified battery charger. Proper AC power source to the ADC-07 is AC100-240V, 50-60Hz. Check

the AC power source before use. Improper AC power source can cause personal injury, emitting

smoke or equipment damage.

The appliance inlet is used to disconnect the power cord when the splicer is abnormal. Be sure to

position the splicer so that it is easy to disconnect the power cord.

Disconnect the AC power cord from the appliance inlet or the wall socket when the equipment emits

smoke or bad smell, or is noisy or heated up. Leaving the abnormal condition can cause a fire,

personal injury or equipment damage.

Disconnect the AC power cord from the appliance inlet or the wall socket when the equipment is

damaged (e.g. by dropping). It may cause personal injury or equipment damage.

Disconnect the AC power cord from the appliance inlet or the wall socket when liquid (e.g. water) or

an object (e.g. screw) enters to inside the splicer. It can cause personal injury or equipment damage.

Do not touch the splicer, AC power cord and AC plug with a wet hand. It can cause personal injury.

Do not operate and maintain the splicer when it is wet with dew. It can cause personal injury or

equipment damage.

Do not use the splicer in circumstance of extremely hot temperature. It may cause personal injury or

equipment damage.

Do not throw the battery pack away into a fire. Or, do not heat it up. It can cause a dangerous

explosion.

Do not short-circuit both terminals of the battery pack and the AC adapter / battery charger. Large

electrical current can cause personal injury, a fire or equipment damage.

Page 8

CAUTION

Do not store the equipment in any area where extreme heat and humidity are present. It may cause

equipment damage.

During / after heating the splice protector, do not touch the ceramic heater and the splice protector.

The high temperature may cause personal injury.

Do not place the splicer at an unstable place. In a case of dropping the equipment, it can cause

personal injury or equipment damage.

Precise adjustment and alignment have been made to this splicer. Do not give a strong shock. Use a

carrying case to transport and store the splicer. The carrying case will prevent damage and provide

protection from moisture, vibration and shock during storage and transportation.

Keep the splicer free from sand or dust. It degrades the splicing performance.

Replace the electrodes properly.

• Only specified electrodes can be used.

• Set the new electrodes to the correct position.

• Replace the electrodes as a pair.

Not following the above cautions can cause abnormal discharge. And, it can result in equipment

damage or degrading the splicing quality.

Do not use any other chemical except alcohol to clean the objective lens, V-groove, mirror, LCD

monitor, body and so on. Doing so may cause blurring, discoloration or deterioration.

The splicer requires no lubrication. Oil may degrade the performance and damage the splicer.

Repair or re-adjustment should be performed by an authorized engineer, except the electrodes

replacement. Failure to repair the equipment can result in personal injury or equipment damage.

Please contact a sales agency in your country.
