1. General use steps: first, prepare enough diesel, engine oil, hydraulic oil and water (for cooling water). Make preparations for fire prevention and protection, and check and repair the system equipment to ensure it is in good condition. After starting the diesel engine with no load, gradually load it to 5-6mpa (no more than 8Mpa), pour part of the coating into the hot-melt kettle for heating and melting. When the coating temperature reaches 100 ~ 150 ℃, start the mixer for mixing, and continuously add new coating in a flow state, and the total amount of coating added shall be less than 4 / 5 of the kettle capacity. When the coating temperature in the kettle reaches 180 ~ 210 ℃, it is in a flow state, Put the liquid paint into the marking machine through the discharge port for marking construction. The feeding and discharging conditions shall be determined according to the quantities, construction time and weather conditions. Under normal circumstances, the materials shall be used up at the end of construction.
2. Before use and during maintenance: make sure that the hydraulic system is not leaking or blocked; Check the gas system for leakage or blockage; Ensure that the nozzle is not blocked or the vent hole is too large. After ignition, the flame is adjusted to be blue; Gas valve control is effective.
3. Replace all the hydraulic oil in the hydraulic oil tank five or six days after the first use, change the oil for the second time a month later, and regularly check and clean the filter of the hydraulic oil tank.
4. Regularly overhaul and maintain the diesel engine.
