found, timely fastening and maintenance are needed. Meanwhile, the screws of the machine should be tightened
one by one with tool after a certain period of use. The first fixation should be performed roughly one month later
after using.

4.2 Electrical inspection

Mainly check the stability of routine supply voltage, and keep the electrical cabinet of the machine tool clean
and well-ventilated. Check the integrity and safety of the lines, check if the emergency stop button functions
normally, test the function of the limit switch and home switch of each axis, and check if the sensor and the drive
work normally. Check if the state of button switches, indicators and warning lights is normal, diagnose and
eliminate the failures of the servo system.

4.2.1 Limit switch

Minimum once a month to make check on the effectiveness of limit switch of the X-axis and Y-axis. The limit
switch plays the role of restraining the limit position of the movement to avoid machine impact (overreaching)
causing damage to the machine. It is a must to make regular check on working state following the steps below:
1. Start up the machine to have the laser head reset;
2. Operate the machine to make the movement shaft move to the limit positions. If the movement shaft
stops at the limit position, it means a normal operation of the limit switch. If it keeps moving while
reaching the limit position, it means that the limit switch is out of order.
In case of hard impact occurs, please immediately press the emergency stop button to stop the machine, and
find a solution for it.
Note

4.2.2 Stop button

Stop button is the safe emergency organ of laser cutting machine; it is relative with the safety of personal
property and machine. You must look-over its functions follow the following steps in the maintenance interval
time of this manual.
Turn on the laser cutting machine and cutting;

Press stop button. If all the power supply of the machine has been switched off, the safe electrocircuit

of stopping is normal. There are 2 stop switches, one is at machine shelves and another is on the
operation terminal, you should look-over them with this method one by one.
Reset the stop button, restart the machine.

4.3 Light route and optics parts maintenance

The optical system of laser cutting machine is determined by the reflection of reflector and focusing of the
focusing lens together. The focusing lens has no offset problem in the optical path. However, after a long work or
due to mechanical vibration, it may cause the optical path offset. Although the reflector won't shift when the
machine is in normal use, it is recommended that the user shall check if the optical path is normal before the
machine is working each time.
The optical lenses of the equipment have specular reflection and focusing effect on the laser beam. Although
we have taken adequate protective measures, the material surfaces may release large amounts of corrosive gases
and dust during laser cutting of the materials easy to produce dust, and the lenses can't completely avoid these
dust pollution. In addition, the lenses are precious and easily damaged under improper use, which isn't covered
by the manufacturer's warranty. Therefore, the lenses require regular cleaning and maintenance. If there is any
