CHAPTER 5
MAINTENANCE
Section I: Precautions
WARNING: Before starting any maintenance, carefully read all instructions, Warnings, and Cautions
DANGER
To prevent eye injury, service personnel, or anyone who may be exposed to Nd:YAG laser
beams, must wear safety goggles having a minimum optical density of 7+ at a 1,064
nanometer wavelength.
Turn the power to the laser OFF and disconnect it from the A.C. source before performing any
maintenance work.
Do not modify the Laser without prior written approval from Amada Miyachi America.
If the high voltage was ON, wait at least 5 minutes for the capacitors to discharge after turning
the power OFF before starting any work. The capacitors store a lethal amount of energy.
When turning power ON to check operation during any maintenance procedure:
Make sure that everyone who may be exposed to the Nd:YAG laser beam during
maintenance, is wearing laser protective glasses.
Never put more than one hand inside of the Laser at any time.
When high voltage is turned ON, the Nd:YAG laser oscillator is enabled.
Use extreme caution while performing any work on the laser.
To operate the laser without the top cover, release the safety interlock switches by pulling them
outward until they are locked in the bypass position. The Interlock bypass lamp (LED) will light
when the top cover safety interlock has been overridden.
Use the appropriate tools for terminating the connection cables, being careful not to nick the wire
conductors.
Keep the exterior of the Laser clean. Use a dry or slightly dampened cloth to clean. If heavily
soiled, use a cloth moistened with a mild detergent or alcohol. Do not use paint thinner, benzene
or acetone.
