[. . . ] The victim should go to see a professional doctor immediately. Before operating the equipment, please tighten all connectors and make sure that the trigger safety of spray gun can be operated safely. When the spraying is stopped, please lock the trigger of spray gun. Check the high-pressure hose and connecting parts everyday. [. . . ] For the coating apt to deposit, it should be mixed regularly and continuously during the spraying process. 4. 6 During the spraying process, the trigger safety of spray gun should be locked in time if the nozzle is being cleaned or replaced or the spraying is stopped. Under no circumstances should the spray gun be pointed at the operator or others, in case the trigger is accidentally pressed causing the high-pressure coating to spray and injure someone. If the spray gun can still be opened after the trigger safety has been locked, the small nut at the end of the drawbar of the gun's valve plug should be adjusted. If the nozzle is blocked, it should be immersed and cleaned with solvent, or cleaned carefully with a brush. Do not poke it with hard things as this may damaging the nozzle. 4. 7 If a airless tip is used during spraying process and the nozzle is slightly blocked, just turn the handle 180 degrees and trigger the spray gun, the dirt in the nozzle will be blown off by the hydraulic pressure of the high-pressure coating itself. If the nozzle is completely blocked, the connecting nut of the nozzle has to be slightly loosened. The handle can only be turned after the coating has been depressurized. If the handle is turned by force while the coating is still pressurized, the handle is easily damaged. While using standard nozzle or airless tip, a sealing ring has to be placed at the joint of the nozzle and the spray gun. 4. 8 If the sprayer has worked continuously for a long time and a severe "frosting" phenomenon has appeared inside and outside the silencer, a water-separating air filter and an air dryer can be installed before the compressed air enters the sprayer, and the silencer can be dismantled. Another way is to replace the engine oil in the oil cup of oil atomizer with "Anti-icing Fluid for Radiator". The water-separating air filter and air dryer will be purchased or manufactured by the customer according to actual needs. The "Anti-icing Fluid for Radiator" is available nationwide. 4. 9 If the spraying operation is finished or will not be used for a long periods of time, the suction pipe should be pulled out of the coating tank in time. The residual coating in the coating pump, the suction pipe, the high-pressure hose and the spray gun should be discharged by running the sprayer idly. Then the whole coating hydraulic loop including the coating pump, the suction pipe, the discharge valve, the high-pressure hose, the airless spray gun and the nozzle should be cleaned by running the sprayer idly with dilution agent or solvent. During the cleaning, the opening of air intake ball valve should be small, the reciprocal time of the sprayer is better to be controlled within 30 to 40 times per minute. 5 5 Common Faults and Trouble-shooting Method Generally, the faults of airless sprayer can be divided into two types: faults in air system and faults in coating system. If a fault occurs, it's prohibited to dismantle blindly. The fault should be analyzed and eliminated step by step as shown in the following table. Before that, the pressure switch should be dismantled and the air intake ball valve should be closed. [. . . ] 2 The equipped nozzle for the product leaving the factory may not meet your actual needs for spraying. There are more than 30 specifications of nozzles manufactured by our factory, which you can order separately as per the requirements for the coating and design of your products and projects. 3 If the spraying equipment is faulty and the fault can not be eliminated after you have carefully read the instruction manual, you can call us on 86-574-88278841 or send email to us at dpairless@gmail. com and clearly describe the fault and the detailed process of the occurrence of the fault. We will promptly advise you of the trouble-shooting methods. [. . . ]
