, 2. Procedure: 1. Turn on the power first when starting on heat gun, turn the switch to the low section (2) or the high section (1) Xin to the "buzzing" sound (indicating that the motor is driving), heating wire thread will turn red slowly, if it turns red badly, it will appear Some smoke, this is because the surface of the heating wire line is coated with a layer of yellow oil for rust prevention. Smoke will disappear soon, and when used for a period of time. Headtube as black. This is a phenomenon occurring at high temperature. There is no harm to the use of heat gun. 2. If the motor does not rotate in use, turn the switch to the position of 0 immediately, pull out the power plug, and then send heat gun of the fault to the point of sale or manufacturer for repair. 3. When you stop using, turn the switch to the O position, and put heat gun of the galvanized iron pipe head up on the plane to make it cool naturally. If galvanized iron pipe heads down, the heat inside will not be released quickly, resulting in an increase in the internal temperature of the motor and a decrease of heat gun in service life. Only when galvanized iron pipe is cold can it be stored. 4. In order to help heat gun cool down and prevent other accidents, when it is stopped, first adjust the heat gun switch from the high section (1) to the low section (2) and then blow it for 15 seconds, then adjust from low Section to 0, and pull out the plug in time. 3. Functions: (1) remove old paint: 1. Using heat gun to remove paint will not cause scorching due to overheating of the surface, but if using other tools to remove paint, such as gas flame or radiation heater, the surface will be easily overheated and scorched. 2. Use heat gun to remove the old paint. When the temperature rises, the paint on the surface of the working object softens, and when the garden softens, it is easy to remove the old paint without damaging the surface of the working object; you 'd better use a flat shovel or blackhead removal peeling, which is safer than blackhead removal peeling. It will damage the surface. Some paints such as cement paint, enamel paint, mineral paint, etc. will not be softened by heat, so heating method cannot be used to remove paint. 3. Please note that when removing paint, it only softens the coating on the surface of the object. After softening, you can easily scrape it off, not burn it. 4. Paint has many types and different properties. Some greasy paint is easy to foam, and others are not easy to foam. It needs a very high temperature to soften, when it is softened to a certain extent, it will become more elastic. It is easier to scrape. 5. No matter how many layers of paint you apply, heat gun can be heated and easily scraped off. You only need to do it patiently, which will make it easier for you to scrape it off. In order to make it easier for the scraper to remove the old paint layer, it is recommended that you heat it back and forth evenly on a large area so that it can be softened evenly. (Ii) bending plastic tube: Heat gun when bending the water pipe, Please heat the air outlet 5-15cm away from the water pipe surface and evenly around the part of the water pipe to be bent until you feel that it has begun to soften. When you feel that the water pipe wall has no resistance, you can bend it and keep it bent until it is completely cooled. Bend a little more during the bending process, because the water pipe will rebound slightly in the opposite direction after cooling. (3) defrost of refrigerator: When defrosting the refrigerator, it is not necessary to melt all the ice, just heat the metal part. The ice next to the metal part will begin to dissolve, and then the whole piece of ice can be easily loosened and removed. For your safety, when you remove ice cubes by hand or touch the parts of the refrigerator with water by hand, please turn off the heat gun in advance and put it aside. (4) heat shrinkage stretch wrap: Use heat gun to heat the shrinkable plastic film. At the beginning of heating, the distance is evenly heated towards shrink film, then slowly approach, evenly shrink and pack the package tightly. (5) use near the glass: It takes a long time to remove the sludge. Although The sludge is easy to be heated, because the sludge is relatively thick, therefore, it takes some time to make the heat penetrate through it. When there is glass nearby, it should be heated slowly, moreover, heat gun ports should not be too close to the glass, which is about 20-38 centimeters. However, we still recommend that you use a protective device I even a piece of wood board) to protect the glass from direct heating. Can remove clay and miscellaneous masonry When changing plastic floor tiles Can strip old wallpaper IV. Precautions: 1. When starting heat gun, do not let it out of your sight. If you want to leave, no matter how short the time is, please unplug the plug first.
