1. be familiar with the relevant manual of lpg forklift truck, and have a comprehensive understanding of lpg conversion system. during the use of forklift truck, forklift truck should not be parked near the source of heat or fire, such as open fire, burning cigarette butt, mars, welding, high temperature machine and electrical equipment; not unauthorized. regular maintenance and inspection shall be carried out on schedule. keep alert and deal with any leakage or abnormal phenomena immediately.
2. reasonable start-up: if using lpg for dual fuel, check whether the manual valve on cylinder is fully opened before work, and close the manual valve when forklift truck is idle for a long time; do not step on the accelerator when starting, the dual fuel system must switch the switch to rotate the lpg position, especially after starting, especially days in cold regions, it is better to warm the car two or three times, let the cooling water system of the internal combustion engine warm up and then run, to ensure that warm water can flow into the carburetor to speed up the vaporization.、
3. pay attention to the fuel switching method (single fuel forklift does not need to be considered): for dual-fuel forklift, when the forklift stops stable, and can not be switched in motion; when gasoline is converted to liquefied petroleum, let the internal combustion engine continue to run at idle speed, at this time the switch can be turned to the middle, so that the carburetor storage of gasoline burnout behavior. when converting from lpg to gasoline, the switch can be switched directly to the position of gasoline without stopping in the middle. at this time, the cable should be pulled out. the dual fuel system should keep at least 1/4 of the fuel in the gasoline tank when mainly burning lpg. quantity for emergency needs. and occasionally need to burn gasoline to ensure that the gasoline system is not idle for too long and failures to prevent the brittleness of the pipeline, it is recommended to burn 10 kilograms of gasoline per month as well.
4., correct aeration: there are two ways to add gas, one is to change bottles, the other is to directly inflate on forklifts. when filling or changing bottles, they must be outdoors to ensure good ventilation and safety should meet the requirements of local fire protection standards. the forklift must be stalled and extinguished. the driver will leave the driver's seat. fireworks, heat sources and fire sources are strictly prohibited. handle cylinders carefully, do not collide, throw or roll on the ground. the gas filling personnel must be monitored throughout the gas filling process and must not leave the scene. when inflating, the air gun sleeve is placed on the filling valve of the bottle and rotated tightly. at the same time, the 80% liquid level hole on the bottle is rotated open, and the gas is started. when 80% liquid level hole has white fog, should immediately stop aeration, 80% liquid level hole closed tightly, and check the level indicator is correct.
