• Small amounts of ultraviolet light may leak from the UV-LED unit. Wear UV safety glasses, face
shields, masks, gloves, and long-sleeved clothing to protect the eyes and skin from ultraviolet
light.
(1) Exposure to ultraviolet light may result in skin inflammation. Even if no inflammation occurs,
extended or repeated exposure may lead to chronic problems.
• Acute problems: Inflammation
• Chronic problems: Skin cancer, wrinkles, blotches
(2) Looking directly at the lamp while the lamp is on may result in eye pain or damage to
eyesight. Even if no eye pain occurs, extended or repeated exposure may lead to chronic
problems.
• Acute problems: Ultraviolet keratitis, conjunctivitis, discomfort, pain, watery eyes
• Chronic problems: Pterygium, cataracts
• The UV-LED unit becomes extremely hot. Be careful not to touch the LED after it has been
turned off until it has sufficiently cooled.
• Do not expose the skin or eyes directly or indirectly to light from the UV-LED unit. The UV-LED
unit emits ultraviolet (UV) light. Skin or eye exposure may result in inflammation.
• Be sure to use the UV safety glasses provided. Disregarding this precaution may result in eye
pain or damage to eyesight.
• Avoid scratching or subjecting the UV-LED unit to excessive force. Disregarding this precaution
may result in deformation or failure of the unit.
• Avoid touching the glass on the underside of the UV-LED unit with bare hands. Disregarding
this precaution may impair UV ink curing. If the glass becomes dirty, wipe clean using a soft,
clean cloth soaked with ethanol. Be careful to keep ethanol from splashing on the covers or
other parts while cleaning. Disregarding this precaution may result in deformation or failure of
the unit.
