Maintenance and care of OUTLOOK telescope & binoculars
I. Storage environment and daily maintenance of OUTLOOK telescope & binoculars
1. Dry and ventilated storage
For long-term storage, a ventilated, dry and temperature-stable environment (ideal temperature 20-25℃, humidity below 65%) should be selected to avoid fogging or moisture on the lens due to excessive temperature difference. It is recommended to place a desiccant in the storage box and replace it regularly. In the humid areas in the south, a moisture-proof box can be used additionally.
2. Shockproof and drop-proof
The OUTLOOK telescope & binoculars adopt an all-metal structure, but it still needs to avoid severe bumps or vibrations. When using, try to use the matching cowhide bag or shockproof bag for protection to reduce the risk of falling due to hand slippage. Do not disassemble the internal components by yourself to avoid damaging the optical axis calibration.
3. Physical protection
OUTLOOK telescope & binoculars should be stored in original cowhide bag or hard storage box, and pad the mirror body and the inner wall of the bag with soft cloth for buffering.
For long-term storage, rotate the focusing wheel to the middle position to avoid long-term compression and deformation of the spring.
II. Lens cleaning and maintenance of OUTLOOK telescope & binoculars
1. Cleaning principles
If there is no obvious stain or sand on the lens surface of OUTLOOK telescope & binoculars, there is no need to wipe it frequently to avoid scratching the coating.
If there is dust, first use a balloon or soft brush to gently brush it, and then use a professional lens cloth to gently wipe it in one direction (from the center to the edge). Oily fingerprints need to be cleaned in time. Staying for more than 48 hours may corrode the coating.
2. Stubborn stain treatment
Use a cotton ball to dip a small amount of industrial alcohol (or diluted neutral detergent) and gently wipe the lens surface to avoid repeated friction. Make sure the lens is completely dry after wiping.
3. Professional cleaning method of OUTLOOK telescope & binoculars
① Air blowing dust removal → ② Special lens pen gently sweep → ③ Drop 1-2 drops of ether/anhydrous alcohol mixture (7:3) on the cotton ball → ④ Spiral wipe from the center to the outside.
III. Sealing and waterproof maintenance of OUTLOOK telescope & binoculars
1. Sealing component inspection
The OUTLOOK telescope & binoculars use sealing wax and drying chamber design, and the sealing of the eyepiece and objective lens interface needs to be checked regularly. If the sealing wax is found to be aging or the desiccant is ineffective (the color does not change with humidity), it is recommended to contact a professional organization for maintenance to avoid self-treatment.
2. Waterproof precautions
Although OUTLOOK telescope & binoculars have certain waterproof performance, it is still necessary to avoid long-term exposure to rain or high humidity. Wipe the mirror body in time after use and dry it in a ventilated place.
IV. Accessories and detail management of OUTLOOK telescope & binoculars
1. Dust cover usage suggestions
In daily use, the protective effect of the dust cover is limited, and the focus should be on avoiding direct contact between the lens and hard objects.
2. Mirror body cleaning
Use a soft cloth to gently wipe the cadmium sulfide rubber coating on the mirror body, and avoid chemical cleaners (such as alcohol) from contacting the rubber parts to prevent aging and cracking. If the telescope rubber coating falls off, it needs to be repaired with special glue or returned to the factory for processing.
V. Emergency treatment plan for OUTLOOK telescope & binoculars
Minor mildew: If mildew is found on the edge of the telescope lens, wipe it with an alcohol cotton ball in one direction. If it is severely mildewed, send it to the factory for disassembly and cleaning.
Glue peeling off: Use cyanoacrylate glue (model 401/495) to stick it, press for 30 seconds to fix it, and do not use 502 glue (corrosive rubber).
VI. Long-term maintenance suggestions
Regular inspection for the OUTLOOK telescope & binoculars: Check the desiccant status, sealing and lens coating integrity every six months.
Professional maintenance for OUTLOOK telescope & binoculars: If there is optical axis deviation, internal mildew or mechanical failure, the telescope needs to be sent to the original factory (such as Yunnan Optical Instrument Factory) or authorized maintenance point for processing. Non-professionals should not disassemble it.
The above care methods can effectively extend the service life of the OUTLOOK telescope & binoculars and maintain its classic optical performance and collection value. If you need to know more about the specific parameters or maintenance channels, you can refer to the experience sharing of the military optical forum or professional collection community.
Note: If stored for more than 1 year, the focus wheel and hinge of the telescope and binoculars should be removed and operated more than 10 times a month to prevent mechanical parts from sticking. It is recommended to keep the original seal for old military lenses, as disassembly and repair will significantly affect the collection value.
