1 Safety Precautions

This machine is for metal cutting. Please do not use it for unintended purposes. If

you have any difficulties operating this product please contact us.

1.1 General Safety Reminders

1). Make sure to read and fully understand the instruction manual and the

programming manual. Ensure that no persons are in danger areas or around

this machine before switching power on.

2). The location of “Emergency-Stop” push-button should be memorized so that

is may be operated at any time. Use it to prevent accidents from happening.

3). Please use safety protective equipment such as security shoes, goggles, to

operate machine. Do not wear loose or baggy clothing to prevent being pulled

into the machine.

4). Do not touch any switch with wet hands, or an electric shock may be

experienced.

5). If a job is to be done by two or more operators, the signal of each step should

be given for each operator. Unless a signal is given and well known, the next

step should not be taken.

6). Never contact a turning spindle or workpiece in any way and never touch tool

nose and cutting chips with bare hands.

7). Never attempt to scrape or remove any signs on machine, and if they become

unlegible, please contact us and replace with a new one.

8). Dispose of filter material and cutting fluids according to the local regulations,

to handle it, dispose of properly.

1.2 Safety Precaution for This Machine

1). This machine is used for metal cutting. Do not use it for other non-metal

cutting. Contact us with further questions for better service and safety.

2). Always keep the machine model and serial number handy to enable us to deal

with your requests rapidly and offer you the best assistance.

3). Warm up the machine before use, especially spindle and feed screws by

running them for 10 to 20 minutes at 1000 rpm of spindle and half the

maximum speed of three axes.

4). Stop the machine before replacing a workpiece and provide plenty of distance

between workpiece and spindle tool to avoid impact.

5). Grip workpieces securely before machining to avoid damage of personnel,

machine or workpieces.

6). Do not open the front door, side covers of safety guard when machine is

working. It may cause the risks of ejected objects, impact or crush.

Chapter 1 Safety Precautions

1-2

7). Tooling should conform to the machine specifications, dimensions and types.

(refer to chapter 2)

8). Lubrication oil is specified (refer to chapter 4). non-recommended oil may

result in malfunctions or damage of machine.

9). After electrical power is lost, return to reference point may be necessary.

1.3 Safety Precaution For Electricity

1). Electrical maintenance should be done by qualified person or others competent

to do the job, don’t change these circuits arbitrarily.

2). Ensure personnel and machine will be operated safely; the earth ground must

be done properly. (details refer to section 3.3)

3). Over-travel limit switches, proximity switches, interlock devices and other

safety devices that have been implemented should not be removed or modified.

4). Some control panels, transformers, motors, junction boxes and other parts with

high-voltage, don’t touch after power switch has been turned on, or you may

get an electric shock.

5). Before replacing a fuse, switch off the main power supply, and make sure to

replace with the proper size and value.

6). In the event of external power supply failure, turn off the main circuit breaker

immediately.

7). Do not change parameter values adjusting and other electrical devices setting

unnecessarily. If such changes are unavoidable, record the original values so

that they can be restored.
