1. Warnings and Cautions for Safe Operation
Read this manual carefully and completely before operating the splicer.
Adhere to all safety instructions and warnings contained in this instruction manual.
Retain this manual for future reference.
WARNING
1) Never operate the splicer in an environment where flammable liquids or vapors exist. Risk of dangerous
fire or explosion may result from the electrical arc in such an environment.
2) Do not use the splicer near any hot equipment or in any place of high temperature .Possible equipment
failure or fire may result.
3) Do not touch the splicer, AC power cord or AC plug if your hand is wet. Possible electric shock may
occur.
4) Do not operate the splicer if water condensation is present on surface of splicer. This may result in
electric shock or equipment failure.
5) The splicer is precision adjusted and aligned. Do not allow the unit to receive a strong shock or impact.
Possible equipment failure may result. Use carrying case to transport and store the splicer. The carrying
case protects the splicer from damage, moisture, vibration and shock during storage and transportation.
6) Do not place the splicer in an unstable or unbalanced position. The splicer may shift and lose balance,
causing the unit to fall. Personal injury or equipment damage may occur.
7) Keep the splicer free from sand, dust, lubricants and other contaminants. The presence of such substances
may degrade the splicing performance and cause equipment failure or damage.
8) Do not use any chemical other than alcohol to clean the objective lens, V-groove, mirror, LCD monitor,
etc., of the splicer. Otherwise, blurring, discoloration, damage or deterioration may result.
9) The splicer requires no lubrication. Oil or grease may degrade the splicing performance and damage the
splicer.
10) Do not use compressed gas or canned air to clean the splicer. They may contain flammable materials that
may ignite during the electrical discharge.
11) Do not store the splicer in any area where temperature and humidity are extremely high. Possible
equipment failure may result.
12) Before using the shoulder belt of carrying case, inspect the belt and hook for excessive wear or damage.
Carrying the case with a damaged belt may cause it to fall and may result in personal injury or equipment
damage.
13) Do not touch the electrodes when the splicer is on and power is supplied to the unit, the electrodes
generate high voltage and high temperatures that may cause a severe shock or burn. Turn the splicer off,
and disconnect the AC power cord, or remove the battery pack when replacing the electrodes. (Note:
Opening the wind protector stops arc discharge.)
14) Use only the 100-240V AC, 50-60Hz/12V DC,14Ah with it. The proper supply voltage source is 100-
240V AC, 50-60Hz, Check the AC Power source before use. Using an improper AC power source may
cause fuming, electric shock or equipment damage and may result in personal injury, death or fire.

15) Use the supplied AC power cord. Do not place heavy objects on the AC power cord. Do not pull heat up
or modify the AC power cord. Use of an improper cord or a damaged cord may cause fuming, electric
shock or equipment damage and may result in personal injury, death or fire.
16) Connect the AC power cord properly to the splicer and wall socket. When inserting the AC plug, make
sure there is no dust or dirt on the terminals. Incomplete engagement may cause fuming, electric shock or
equipment damage and may result in personal I jury, death or fire.
17) It uses a three-prong (core) AC cord that contains an earthed ground safety mechanism. The splicer
MUST be Grounded/Earthed. Use only the supplied three-prong (core) AC power cord. NEVER use a
two-prong (core) power cord, extension cable or plug.
18) Use only the approved battery pack with the machine. Only the battery pack can be used as the approved
battery pack.
19) Use the specified charger cord to recharge the battery pack. Using other battery chargers and charger
cords may cause fuming or equipment damage and result in personal injury, or death and it could cause a
fire.
20) The splicer inlet is used to disconnect the power cord in the event of a fault. Be sure to position the splicer
so that the power cord can be disconnected easily and quickly.
21) Disconnect the AC or DC power cord from the splicer inlet or the wall socket (outlet) immediately if the
splicer or the external battery emits fumes, a bad smell, or becomes noisy or hot. Leaving the abnormal
condition unattended will cause equipment failure, electric shock or fire and may result in personal injury,
death or fire.
22) Disconnect the AC or DC power cord from the splicer inlet or the wall socket (outlet) immediately if
liquid (e.g., water) or foreign matter (e.g., screw) enters the splicer. Leaving the splicer in a damaged state
may cause equipment failure, electric shock or fire and may result in personal injury, death or fire.
23) Caution should be taken when removing the fiber protection sleeve from the tube heater after the heat
shrink cycle is completed. The tube heater and fiber protection sleeve are hot and should not be touched.
Possible burn may result
24) Replace the electrodes properly.
oUse only specified electrodes.
oSet the new electrodes in the correct position.
oReplace the electrodes as a pair.
Disregard of the above instructions may cause abnormal arc discharge and result in equipment damage or
degradation in splicing performance.
25) The equipment must be repaired or adjusted by a qualified technician or engineer. Incorrect repairs may
cause fire or electric shock. Should any problem arise, please contact your nearest sales agency.

Fiber Cleaving
1) Open the cover and pressure pad. Put the stripped fiber on the V-groove. And make sure that the cleaver
length is set as per operators’ intended length.
2) Close the pressure pad to fix the fiber.
3) Close the cover and make sure that the end of the fiber is sticking out of the rubber pad exactly in a
straight line.
4) Push the blade carriage to the rear until it stops.
5) Open the cover
6) Take out the cleaved fiber with care in order not to bring the harm to the end face of fiber.
7) For continuous operation, remove the cleaved fiber in this process. Be careful not to get injured by the
cutting edge.
Fig3-4 Fiber Cleaving
3.6. Setting Fiber in Splicer
1) Open the wind protector.
2) Open the left and right sheath clamps.
3) Place fiber in the V-groove.
Check: Make sure the fiber is not twisted when setting it into the splicer.
Check: If the fiber coating has curl memory, or bend memory, load the fiber in such a manner that the
crown (curve) of the memory is turn upward.
Check: Care should be taken to prevent damage or contamination of the fiber end-face. Fiber end-face
contact on ANY item including V-groove bottom may result in poor quality splices.

4) Gently close the sheath clamp while holding the fiber.
Check: Observe fiber setting in the V-groove. The fiber should rest in the bottom of the V-groove. Reload
fiber if it does not rest properly.
Check: Fiber end-face should rest between the V-groove tip and electrode center line. It is unnecessary
that the fiber end-face be exactly at the midpoint.
