Safety warnings and precautions
The OFS-941V is designed for fusion splicing silica glass optical fibers, it is very important that the splicer should
not be used for any other purposes. The splicer is a precision instrument and must be handled with caution.
Therefore, you must read the following safety rules and general precautions in this manual regarding the use and
handling of OFS-941V at any time. Any behaviors that do not follow the warnings and cautions will break the
safety standard about design, manufacture, and usage of the fusion splicer. Precision Rated Optics will not take
the responsibility for those consequences caused by misuse!
Operational safety warnings
• Never operate the splicer in an environment where flammable liquids or vapors exist.
• DO NOT touch the electrodes when the splicer is on.
Note: Only use specified electrodes for the fusion splicer. Select [Replace electrode] in maintenance menu to
replace electrodes, or turn off the splicer and disconnect the AC power source or remove battery before replacing
electrodes. Discharging is prohibited before the electrodes are placed as a pair.
• DO NOT disassemble or modify any components of the splicer without approval, except for the permitted-to-
disassemble / modify components or parts by users stated in this manual. Component replacement and its internal
adjustment must be implemented by Precision Rated Optics or its authorized technicians or engineers.
• Never operate the splicer in an environment where flammable liquids or vapors exist. Risk of dangerous fire or
explosion could result from the splicer’s electrical arc in such an environment. DO NOT operate the splicer near
hot objects or in high temperature and dusty / humid atmosphere, or when condensation is present on the splicer.
This may result in electric shock, splicer malfunction, or poor splicing performance. Users should always wear
safety glasses during fiber preparation and splicing operation. Fiber fragments can be extremely dangerous if they
are ingested or come into contact with eyes, skin.
• Take out the battery immediately if the followings are observed when using the splicer:
• Fumes, bad smell, abnormal noise or over heat.
• Liquid or other matter falls into cabinet
• The splicer is damaged or dropped.
Note: If any of these faults occurs, please contact our service center immediately. Leaving the splicer in a
damaged state without any prompt measures may cause equipment failure, electric shock, or fire and may result in
injury or death.
• Do not use compressed gas or canned air to clean the splicer. They may contain flammable materials that could
ignite during the electrical discharge.
• Please use OFS-941V designed battery only. Using an improper AC power source may cause fuming, electric
shock or equipment damage and may even result in fire, injury or death.
• Please use OFS-941V designed charger only. Do not place any heavy objects on the AC power cord. Keep the
power cord away from heat source. Using an improper cord or a damaged cord may cause fuming, electric shock
or equipment damage and may even result in fire, injury or death.
