required for repair or installation, do as best as possible to arrange the work in a special
workshop or on a designated site.For occasional welding or the like work directly in
production area or warehouse, submit written applications to a correlated supervisor in
advance for written approval. Only can the above mentioned operations be carried out
when special safety measures have been taken, such as laying water soaked canvas or a
special fire-resistant canvas with fire extinguishers standing by. After completion of the
operation, monitor the welding site and the surrounding area for at least 10 hours.

The torch cutting sparks are very dangerous. They can travel across through the narrow
clearance of walls and drop downstairs or to the next rooms, or even fly off 10m away in
distance. If the sparks drop in dusts, fire accidents may occur at any time.
⑤
Welding is prohibited on a running conveyor. If the welding work is a must, shut down
the conveyor first, and then make a thorough cleaning and isolate both sides of the
welding site tightly with materials like mineral wool to avoid connecting with other
conveying devices, silos or tanks. If the chutes or conveying pipes require welding work,
disassemble them or disconnect their lower ends with silo or tank and seal them to avoid
welding sparks entering the conveying pipes or silos.
(5) Beware of static electricity
①
To ensure the safety of electric circuits and avoid explosion resulted from spark
discharge.
②
The paint coat at the electric connections must be removed.
1.9 Other safety precautions (environmental protection measurements)
If you decide not to use the machine any longer after it is used for a certain number of years
(about 8-10 years), take the actions for environmental protection and parts reutilization.
(1) Drain the liquids inside the machine (like motor oil, gearbox oil, brake oil and coolant
etc.) into special containers and send them to the designated workshop.
(2) Pick up the plastic parts for reutilization.
(3) Sort out the metal parts for special handling.
