1Safety Instructions
1.1 General Safety Rules
Operator must read the instructions carefully before operating the machine, and the manager of safety
department should assure the operator knows the requirements well.
1）The operation, maintenance and repair of the machine must be done by qualified persons who have been
trained the ability to forecast the potential risks. Only safety-conscious persons who are fully aware of the
risks can operate the machine.
2）To those people who assemble, operate, or maintain the machine must be confirmed to have read and
understood the operating instructions.
3）After stopping the machine, the chuck will still run for a period of time due to inertia, so you need to pay
extremely attention to the chuck when you remove the chuck guard and fetch the workpiece.
4）Do not detach or modify any safety guard. Be sure that the machine is disconnected from the power when
adjusting, maintenance and repair.
5）Do not dismantle any safety precaution sign attached to the machine. They should always be kept clean
and legible.
WARNING! Never touch the tool or any other driving parts with hands when they are still turning.
6）Assign only special persons to operate, maintain and adjust the machine.
7）Operate the machine in accordance with technological process. Only qualified persons can completely
repair the machine.
8）Use standard spanners and pliers for adjustment and repair.
9）Stop the machine immediately if an abnormality occurs. Ask for qualified persons to check and repair.
10）Dismantle and assembly the machine with the hoisting equipment which is of enough load capacity.
11）Observe all safety instructions and warnings attached to the machine; make sure they are always
complete and perfectly legible.
12）Do safety inspection before operating. Be sure that limit switches for each axis, stop dogs and emergency
stop button are all in good condition.
13）Reinstalled the removed guards and safety devices in place after maintaining.
14）Do maintenance or adjustment only after switch the machine off and remove the plug from the power
source outlet, until all moving parts absolutely stop.
15）Always keep children away from the machine. Operating personal must be at least 18 years of age.
16）Do not wear loose clothing, gloves, neckties or jewelry (rings, watches, etc). Keep the sleeves and the
edges of the work uniform tight. Always be sure to wear safety goggles and safety shoes during
operation.
17）Those with long hair, no matter whether it is a man or woman, should wear safety hat and wrap the hair in

CS6140, CS6140B Series Turning Machine Instructions

when operating.
18）The machine was inspected carefully before shipment from factory. Its noise emission is not higher than
81dB. Wear suitable personal protective equipment when necessary, for instance, wear hearing
protection to reduce the risk of induced hearing loss.
19）Provide adequate light around the machine, and keep the perimeter around the machine dry, clean and in
good order. In addition, do not place anything near the machine; otherwise it becomes an obstacle during
operation.
20）Do not move away any guard during all working.
21）Isolate the machine from the power sources when leaving the machine.
22）Restart the machine only after the guards and safety devices are replaced to their position.
23）Do not place tools, work-pieces or other items on the machine, especially on the moving parts.
24）Do not start the spindle unless the workpiece is clamped completely in the chuck, and the key is taken
away from the chuck and the chuck guard is closed.
25）When chucking an irregular-shaped workpiece, make some adjustments to center of its gravity so that the
workpiece can rotate steadily.
26）Stop the machine before adjusting the position of the coolant nozzles.
27）Avoid as much as possible, using compressed air to remove dust and chips etc. deposited on the
machine, switchboard, NC controller etc.
28）The fixtures to be set on the machine must have sufficient rigidity and proper steps should be taken so that
the surface of the fixtures will be slip-free.
29）Both operators and the maintenance men should read with care the description on the caution plate
attached to the machine. They should observe the precautions on this plate during their work. During
operation and maintenance, care should be used so that this caution plate is not dirtied or damaged..
30）Memorize where the emergency stop push button is so that it can be depressed without delay in case of
an emergency.
31）Follow the starting procedures given in this manual to start the machine.
32）Keep your hands away from the moving parts of the machine during operation.
33）Do not get direct access to the work light when it is on. That may cause being scalded.
34）Never remove chips from machine during operation. Especially do not handle chips with hands.
35）When removing chips caught around the turret or deposited on machine, take them out with a tool instead
of hand, because your hand may be injured. Be sure to stop the machine when removing chips from it.
36）Prior to starting test operation, carefully read this manual so as to be completely familiar withthis machine.
37）Contact this company if for some reason the manual should become unreadable.
