SAFETY PRECAUTIONS
Operation and maintenance involve potential hazards. All operators and
personnel should be alerted to possible hazards and precautions should
be taken to prevent possible injury.
Electrical safety
Maintenance
Individual safety
Machine：
﹡Terminate the main power on the external NFB.
﹡
The counter, safety device against excess current and electrical installation, are
compatible with its maximum power and its main voltage.
﹡
The connection, single-phase or three-phase, is possible on a stand compatible
with the plug of its cable link.
﹡
If the cable is connected with the electrical network, the earth, must never be cut by
the protection device against electrical shocks.
Work place：
﹡
Be very careful to avoid contact between metal part and phase conductor and the
neutral of electric network.
﹡
Electrical messes of different electrical machine and apparatus are connected
between themselves and with the terminal of earth neutral wire.
Interventions：
﹡
Before control and repair, see the apparatus is switched off and insulated.
﹡
Connection with fixed installation cable is impossible.
﹡
Switch off by fixed connection is multi-polar (phase and neutral).
﹡
It’s on “Stop” and connection is impossible.
﹡
Some apparatus are provided with starting circuit HT HF (with a plate). Never enter
into the corresponding switch cupboard.
﹡
Only qualified persons are authorized for intervention concerning electrical
installation.
﹡Often check the insulation and connection good state Of apparatus and electrical
accessories: taps, appliance cords, coatings, switch, extension cords, etc.
﹡Maintenance and repair of insulating coatings operations are very important.
﹡
Do repair with a specialist or better replace defective accessories.
﹡
Check regularly the right adjustment and the non-heating of electrical connections.
﹡
The operator must be dressed and protected in relation with his work.
﹡
Avoid contacting metal parts connected or accidentally connected.
﹡Wear leather gloves with gauntlet.
﹡
Safety clothes: gloves, apron, safety shoes protect the operator and his assistants
against burns of hot parts, projections and slag.

2.1 MAINTENANCE
Routine maintenance *After using the machine, make sure to turn off the input main power to
prevent the leakage of the electricity.
*To make sure the function of the machine could work well for a long time,
please keep clean all around the machine and the switch from the oil
pollution.
*To make the machine run normally, the control box, the machine and the
table should be kept clean all the time.
*Check regularly the lubrication of the reducer to extend the lifetime of the
machine.
*Check cable if damaged or melted due to overheat.
*Check the contactor, relay and other connectors if loosen or melted.
*Check every limit switch is fixed or loses function.
*Give the machine cleaning and the anti-rust maintenance regularly.
*Change and refill the lubrication of the worm reducer regularly.
