II.Attention
DO NOT:
No dismantle the hi-pot modules in the gun.
No replace any original units in the main board.
No tighten the pressure regulating valve without read the air pressure meter.
No gun fire without the ground wire connection.
No measure the electric parameter or decomposition for the main body, no touch to the part by the discharge rod through the electricity process or in the working area.
The electro-static output voltage is much high. No touch to the discharge rod at the end of the gun.
Do:
Do the de-oiling, de-rusting, and de-dusting treatment with the part, recommend phosphating treatment before coating.
Do the oil-water separate with the hi-pot air used in the electro-static powder coating.
Do the good grounding wire connection with the grounding terminal of the system and good induction to the part.
III. Operation and maintenance
1.before the power on, check every circuit both the electricity and air. Ensure they are ok and the equipment is reliable grounding connection. (after power on, check the shell with electricity or not by the electricity testing pen, till it is verified no electricity, and then run it.)
2.powder coating (spraying):after adjustment, slightly swing the gun, coating the part vertically. Provided fiercely swinging the gun affect the powder coating quality. After working, dismantle the pressing nut (the gun head sleeve) and clean the motor rod and powder disperse sleeve.
3.place them in queue according to the dismantle steps. Regularly clean the lining pipe (the copper pipe inserted into the powder) to the powder absorption pump as it is easily got jam by the sticky powder. Clean the thread of the nut before the installation. Attention: dismantle or assembly the gun head need be done by the skillful technician.
4.the fluidizing board in the powder barrel is fragile product, don't put heavy item or any other item inside, also don't slash it.
5.don't crash the hard item by the gun head.
6.the hanging hooker need be regularly cleaned to ensure good grounding wire connection to achieve qualified coating.
7.the powder used in the coating need be ensured dry.
8.after coating, clean every powder pipe by the air.
9.regularly do the maintenance for the gun and the relative facility as the air compressor, oil-water separator etc.
10.powder feeding and powder disperse sleeve are wear parts, replace them in time.
11.regularly check the air pipe, powder pipe.
12.be surely the powder and air source be dry.
13.The normal working relies on the electro-static absorption effect principle. Keep the working environment dry to ensure the hi-pot electro-static can work well. Especially ensure the gun be dry and clean.(if any contamination substance left in the gun, it is easily absorb moisture and electricity shock, which affect the coating quality and gun life.
14.grounding wire connection: it has the grounding cable, at the installation moment, be surely to connect with the coating room, and better to have the specially used grounding rod for the coating room. Part, hanging device, rack should be connected with the coating room ground wire, to avoid discharge sound resulting from improper grounding connection.
15.avoid unevenly powder feeding: if the equipment appears unevenly powder feeding, normally it comes from powder feeding pressure and coating pressure is incorrect.
