V.System operation
5.1. Pre-operational inspection:
5.1.1 If the anti-solidification lubricant reservoir contains DOP (dioctyl o-phthalate) of no less than 4/5 of
the reservoir volume.
5.1.2 .Check that all joints are securely tight
5.1.3. Check that power line is connected correctly. And the protective grounding wire is connected safely
and reliably.
5.1.4. Check that all switches are in OFF position.
5.1.5. Check whether the air source regulator was switched to OFF position.
It is prohibited that placing any part of the body in the path of the material spray, pointing the gun at or
near other persons and looking at the mixing chamber orifice at any time. Because of the hazardous
materials used in the equipment, it is recommended that the operator use an air mask, goggles, protective
clothing and other safety equipments. Before operating, the operator must read the caution text on the
previous page of this manual.
5.2. Initial start-up: (first installation and operation of new equipment)
After satisfactory confirmation of the connection of all the stream tubes, air hoses, and power cables, the
system may be operated. The operator must fully understand each function of the control instrument and
have necessary precautions ready.
The steps are as follows:
Step 1:Switch on the main power knob and adjust the pressure regulator knob of the main air valve to gain
a pressure of 0.2Mpa.
Step 2:Push the run/retract knob to the operation position. Then, the main machine starts up and the
material pipe system is filled with feed material and the heat preservation hose is heated. The equipment
stops once the material is filled full.
Step 3: Remove the two conveying material pieces on both sides of the tip chamber.
Step 4: Place a clean container under the two conveying material pieces respectively, at the same time open
material valve of the two pieces slowly for emptying all air in the conveying pipe until the raw materials
spraying out smoothly. See figure13
