.1. Guideline for Safety Operation
The lathe is a high speed and powerful machine and can cause danger
if operate it improperly.
Before operating the lathe please read the following guidelines of
safety operation. Take care and observe to make the lathe be under
normal operation environment so as to avoid danger.
The lathe is in accordance with GB15760-1995 <General Technical
Condition of Safety Protection of Metal Cutting Machine> issued by the
state.
The manual covers information and hints necessary for proper and safe
operation of the lathe.
It is required the operator of the lathe should accept suitable technical
training before operating the machine, own skills to operate it and hold
the certificate of operation; or he should be trained under the close
supervision of somebody who can skillfully operate the machine.
The lathe should be operated under the environmental temperature of
+5°C - +40°C; the elevation up to 1000 m; the relative humidity of 50%
when ambient temperature is +40°C or higher relative humidity if
ambient temperature is lower.
The manual also covers related information for those who owns
necessary skills or appointed persons to make suitable maintenance upon
the machine.
1-1 Safety Points forAttention
1. Keep the lathe and the working area clean and in good order.
2. All guard devices and cover plates should be on the place; the side
cover should be closed.
3. Do not place any objects in the processing area of the lathe as they
may bump with rotating or moving parts.
4. Do not contact or leap over moving or rotating parts of the lathe.

5. Before starting the lathe, you should understand how to stop it.
6. The lathe cannot be operated under overload.
7. Stop running of the lathe immediately in case any accident occurs.
8. When mounting the chuck or other attachment on the spindle, switch
off power supply of the lathe to prevent rotation of the spindle.
9. Do not mount the jigger if it is not checked of confirmed to be
compatible with the lathe.
10. Check the center you used if its load capacity can meet with
requirement.
11. Switch off power supply before leaving the lathe.
12. The maximum weight of the workpiece on the lathe is 500 kg.
13. The chuck should be properly and firmly mounted on the spindle of
the lathe.
14. Take care that the workpiece should be gripped firmly and the
speed of the spindle cannot exceed the safe speed of the chuck.
15. As it is possible to contact with human body, especially when the
material with small diameter is used, it is not allowed in any case that the
rod material cannot extend out the end of the spindle of the headstock
which has no special guard and relative support.
16. There is the label of speed limit for the chuck and that no speed
change is allowed in operation at the lower right corner of the headstock,
the electric warning board at the electric cabinet (box) and that no touch
on the workpiece (or chuck) when it is rotating on the guard of the chuck
to remind you to take care.
1-2 Danger of Operation
When operating the lathe you should fully understand the danger of
following operations:
1) Cutting Fluid
The cutting fluid is hazardous to human body. To contact the cutting

fluid continuously especially the original fluid, it can cause the skin
allergic or ill if seriously, even the emulsion can also cause the same.
Therefore following precautions should be taken:
a. Avoid any unnecessary contact.
b. Put on the protective clothes.
c. Adopt guard shield or plate.
d. Do not wear oily or dirt clothes.
e. Clean all parts of the body where the cutting fluid is contacted after
work.
f. Do not mix different cutting fluids.
g. Replace the cutting fluid regularly.
h. Correctly treat the cutting fluid.
2) Safe Operation of the Chuck of the Lathe
All jiggers of work pieces should have clear labels of the maximum
safe speed and the speed of the spindle can never exceed it. It should
point out that the maximum safe speed on the label is supposed under
ideal work condition and lower speed of the spindle should be selected in
following cases:
a. Adopt the chuck to jig the workpiece under noisy work condition.
b. If the chuck is surely damaged, it is dangerous to operate under high
speed, especially when the chuck of grey pig iron is used it shall break if
it is something damaged.
c. If no griping force is known before jigging.
d. All factors such as strength of the workpiece to be jigged, balance of
the jigging faces and the workpiece etc. can largely affect the maximum
safe speed.
When the workpiece is rotation, it may not be jigged firmly due to the
role of centrifugal force and following factors may be involved:
a. The speed is too high.

b. The weight and type of the claws are off standard.
c. The working radius of the claw is unsuitable.
d. The claw ahs bad lubrication.
e. It is unbalanced.
f. The dynamic factor is not considered in the jigging force.
g. Too large cutting force.
h. Is the workpiece jigged internally or externally?
These factors should be seriously considered as they can cause
different influence in different purposes. The manufacturer cannot
provide concrete data for general use as they are beyond the range
controlled by the manufacturer of the machine.
1-3 General Safe Rules for Operator of the Lathe
1. When jigging the workpiece, it cannot have oil or grease;
All parts should be jigged firmly;
Do not intend to jig the workpiece which is unsuitable or hardly to jig
well;
Do not jig the workpiece exceeding the weight allowed by the lathe;
Master suitable hoisting method when the workpiece is hoisted.
2. Ensure to remove oil or grease on handy tools and operation
grippers;
Ensure the structures of handy tools and operation grippers are suitable
to touch safely by hand.
3. When operating the handy tool or the operation gripper, it should be
gripped firmly;
Select suitable position to grasp on the handy tool or the operation
gripper;
You cannot grasp the handy tool or the operation gripper on unsuitable
