Metal Lathe Safety Instructions
1. Maintenance. Make sure the lathe is turned off and
disconnect from the main power supply and make
sure all moving parts have come to a complete stop
before any inspection, adjustment or maintenance is
carried out.
2. Lathe Condition. Lathe must be maintained for a
proper working condition. Never operate a lathe
that has damaged or worn parts. Scheduled routine
maintenance should performed on a scheduled
basis.
3. Leaving a Lathe Unattended. Always shut the
lathe off and make sure all moving parts have come
to a complete stop before leaving the lathe. An
unsupervised running lathe can cause serious injury.
4. Avoiding Entanglement. Remove loose clothing,
belts, or jewelry items. Tie up long hair and use the
correct hair nets to avoid any entanglement with
moving parts.
5. Chuck key safety. Never let go of a chuck key while
still in the chuck to prevent leaving the chuck key in
the chuck. Chuck keys left in the chuck can cause
serious injury.
6. Changing Chucks. When changing large heavy
chucks they become awkward to hold. Always get
assistance when installing large chucks. Use a board
or piece of plywood across the bedway when any
install or removal of chucks to avoid any possible
finger pinching between a loose chuck and edge of
a bedway.
7. Tooling selection. Always use the correct cutting
tool for the job you are turning. Make sure it is sharp
and held firmly in the tool post. Adjust the toolpost to
provide proper support for the tool you will be using.
8. Mounting the workpiece. Make sure the workpiece
is properly mounted and secure before turning on
the lathe. A loose workpiece can be thrown across
the room and cause serious injury to you or a
bystander.
9. Workpiece clearance. Rotate the workpiece by
hand to check for clearance with the tool post,
compound slide and carriage before turning the lathe
on.
10. Changing speeds and Reversing. Turn the
lathe off and make sure the lathe has come to a
complete stop before changing speeds or reversing
the spindle. Do not slow or stop the lathe chuck by
using you hand.
11. Speed selection. Select the appropriate speed for
the type of work, material, and tool bit. Allow the
lathe to reach full speed before beginning a cut.
12. Clearing chips. Always use a brush to clear chips.
Never clear chips when the lathe is running.
13. Power outage. In the event of a power failure
during use of the lathe, turn off all switches to avoid
possible sudden start up once power is restored.
14. Clean work area. Keep the area around the lathe
clean from oil, tools and chips.

2. ELECTRICAL CIRCUIT CONTROL
2-1 Electrical Wiring
1. The electrical control box can be found by opening its cover at the back side of
bed. Connect the power source wire with the connecting points (R.S.T)
The wire between the power source and the connecting points must be over sectional
area 8mm2(5.5 mm2for 480 or 19” series).
2. The main switch between machine and power
source also should be equipped with safety fuse.
Besides, the machine must have a earth wire.
Fig.2-1
2-2 Electrical Equipment
1. The electrical control box is also equipped with overload circuit breaker and
electric magnetic contactor to protect motor from burning out by overload.
2. The forward/reverse switch is connected with micro switch.
3. The foot brake is connected with micro switch. Stepping the footbrake is quicker to
stop the lathe than turning off the switch. The spindle can only revolute again by
re-operating the spindle operation control lever after using the foot brake.
4. The spindle will rotate continuously as long as the intermittent switch on the top of
the electrical control box is pressed.

2-3 Electrical Cautions
1. After wiring, check the rotation of the spindle of the spindle. Turn the main
switch “ON” and make sure the safety of spindle. Then push intermittent button
(T) momentarily. The correction direction of the spindle rotation is counter
clockwise. (looking from tailstock for a downward movement of the spindle
operation control lever.) Wrong direction of rotation can be rectified by
interchanging any two of the three phase lines (R.S.T.) in the power source.
2. Checking each lubrication system with oil.
3. Checking each handle with normal function.
4. Checking belt Tension Adjustment in good condition.
5. Read and understand for each constructer well before operation.
6. When power indicator “ON”, overload circuit breaker and electric magnetic
contactor to protect motor from burning out by overload, please reset the circuit
breaker by press the recover plate and lathe will resume to available. (The
electric wiring attached at chapter 2-4)
