DEAR CUSTOMER
Congratulations. You have made a good choice when you decided to buy a GNATUS QUALITY
product comparable to the best products available in the World. This manual is a general presentation of
your product and it will give you important details to help you to solve possible problems.
Please, read it and keep this with you.
PRODUCT DESCRIPTION
The Optilight LD Max belongs to the newest generation of LED photo-activation devices. This
abbreviation stands for Light Emitting Diode, a totally different type of light emission, if compared to
conventional halogen equipment.
Unlike traditional devices, which generate wide-spectrum light and heat, this technology uses a cold
light of the precise wave length needed to activate various dental products.
LED technology, which was recently introduced in Dentistry, brought about several useful features to
those light-curing devices used in composite resin restoration. Besides being more durable, LED technology
turned devices more compact, ergonomic and easier to install and transport. The emission of cold light
within a precise wave length range ensures the safe cure of camphorquinone-activated composites,
preventing dental heating, pulp damage or discomfort for both patient and dentist. Although being relatively
new, this technology is nowadays in its second generation. LED safety and efficiency, now allied to highenergy emission, are available to all clinic procedures which require light-curing power, including bleaching
treatments.
The light of 440nm-460nm wave length, allied to the high energy emitted by Optilight LD Max, makes
possible the multi-functionality of this device:
- Direct restoration procedures: composite resins, ionomers and adhesives.
- Indirect restorations: adhesive cementation of laminates, inlays, esthetic pins and metal-free
crowns.
- Dental Bleaching: activation of bleaching gel and polymerization of gingival barriers. Compatible
with 35% hydrogen peroxide-based bleaching gels.
- Attachment of braces and orthodontic accessories.
- Activation of light-cure materials, such as sealants, surgical cements and covering bases.
English
Designed and built with cutting-edge technology, it meets the highest standards specified by world’s
dental authorities.
It features an automatic bi-voltage power supply, which allows operation in the range of 90 to 240 V
AC, 50/60 Hz.
Operation control display in handpiece, sound alarm with beep every 10 seconds and 4 beeps at the
end of the cycle.
Advantages offered by Optilight LD Max:
- More spectrally-selective light than conventional lamps.*
- Cold light, it doesn’t heat up the resin nor the tooth**
• Light compact equipment that provides handling comfort.
• Low power consumption.
• Longer useful life of the light emitting diode (equivalent to 36.000.000 cycles of 10 seconds).
• It does not use optical filter.
• It does not require forced ventilation, thus avoiding noise emission.
* We noted that the light emitted by the Optilight LD Max is completely contained within the absorption
interval of the photo starter, therefore it’s 100% used, whereas the conventional equipment running on
halogen lamps has non-used wave-length regions.
** The Optilight LD Max doesn’t generate heat since it uses light emitting diodes.
The light conductor is removable, made out of high resistance polymer and of easy maintenance.
The handpiece’s low weight and its anatomic design ensure the dentist more comfortable and practical
handling.

• For your safety the Optilight LD Max is equipped with an automatic bi-voltage power supply of
90V~-240V~ - 50/60Hz.
• Plug in the power supply (01) to the electrical outlet.
• Select application time, press time selection button (10), which values are: 10s (standard mode),
20s, 60s, 80s and 90s.
• To initiate a polymerization cycle, press the timer trigger (09), which generates a short beep every
10 seconds and a 4 beeps at the end of the cycle.
• To interrupt a polymerization cycle just activate the timer trigger again (09).
IMPORTANT:
• Keep the light conductor tip (06) at least 2mm away from the restoration.
• Keep the light conductor (06) always protected by an expendable PVC film, which must be changed
for every patient. This procedure protects the light conductor from scratches and other residues.
• Use the polymerization time recommended by the compound resin manufacturer and always
perform restorations in incremental layers with a maximum thickness of 2mm.
Instructions for equipment operation
WARNING
• Never aim the blue light beam towards the eyes
• Use the eyesight protection (05)
In order to protect the eyes, the eyesight protection (05) filters only the blue light used for the resins
polimerization, and it allows ambient light to pass through.

MAINTENANCE
Recommendations for the dental equipment maintenance.
Your Gnatus equipment has been designed and developed according to the standards of modern
techology. Similarly to other kinds of equipment, it requires special care, which is many times neglected
due to several reasons and circunstances.
Therefore, here are some important reminders for your daily routine. Try to follow these simple rules,
which will save you a lot of time and will avoid unnecessary expenses once they start making part of your
working procedure.
Precautions
- Install your equipment in an appropriate place away from sunlight exposure and humidity.
- The equipment and the light conductor cannot be placed in the oven or autoclaves.
- The conductor can’t be immersed in solvents or substances that contain acetone in its composition.
- Avoid the light conductor to terminal to touch the resin to be polymerized.
- When using the Optilight LD Max check if the light conductor output doesn’t have residues that
might obstruct the light beam.
INTERCHANGEABLE AND/OR REMOVABLE PARTS REPLACEMENT
If stains, fissures or scratchs where detected in the eyesight protection or in the light conductor,
replace damaged components.
Cleaning conductor
The light conductor cleaning and the optical protector must be done using only neutral soap and
cotton. To the exterior of the pen use neutral soap or alcohol 70% vol.
Never use any other chemical based product than previous mentioned, because along the time
these products attack the surface of the instrument.
Never immerse the instrument in disinfection baths.
English
Cleaning the equipment
To clean the equipment, we recommend the use of “BactSpray (Reg nº MS:
3.2079.0041.001-5) or any other similar product:
Active component: Benzalkonium chloride (tri-quaternary ammonium)
Solution 50%................................................. 0.329%
Chemical composition: Butyl Glycol, Decyl polyglucose, Sodium Benzoate, Sodium
Nitrate, Essence, Deodorized Propane / Butane, demineralized Water.
For more information concerning cleaning procedures, see manufacturer’s
instructions.
WARNING:
• In order to prevent risks and damages to equipment, make sure that the liquid does
not enter into the unit.
• The application of other solvent-based cleaning products or sodium hypochloride
isn’t recommended, because they may damage the equipment.

- Provide proper resin for the
photo polymerizator wave
lenght, the ones which contains
photo initiators with alcanphor
quinone.
