Where to Bleed Air After a Forklift Runs Out of Fuel?

Bleed air from the bleeder screw on the brake caliper. Below is a related introduction: Loader: A loader is a type of earthmoving machinery widely used in construction projects such as highways, railways, building hydroelectric projects, ports, and mines. It is primarily used for shoveling and loading loose materials like soil, sand, gravel, lime, and coal, and can also perform light digging operations on ores and hard soil. By equipping different auxiliary working devices, it can also perform tasks such as bulldozing, lifting, and handling other materials like timber. Function: In road construction, especially in high-grade highway projects, loaders are used for filling and excavating in foundation engineering, as well as for gathering and loading materials like asphalt mixtures and cement concrete. Additionally, they can perform tasks such as pushing soil, leveling the ground, and towing other machinery. Due to their advantages of fast operation speed, high efficiency, excellent mobility, and ease of operation, loaders have become one of the main types of machinery in earthmoving operations for construction projects.
That day at the construction site, the loader ran out of fuel and stalled. After refueling, you need to bleed the air first before it can start. I most commonly bleed air from the diesel filter. Look for that cylindrical filter near the engine, there's a small screw or bleeder valve on top. First, loosen it with a wrench, then use a hand primer or electric fuel pump to pump a few times until the diesel coming out has no bubbles, then tighten it. If it still doesn't start, you'll need to bleed air at the high-pressure fuel pump, usually located on the side of the engine, with similar steps. After bleeding, I always check the fuel flow at the injector connections to ensure it's smooth, as incomplete air bleeding can easily damage the fuel pump system.
I've been operating loaders for over a decade and have dealt with countless cases of air in fuel lines. The most reliable method is to start bleeding from the source of the fuel system. First locate the filter near the fuel tank outlet pipe, loosen the vent screw on top, and use the manual fuel pump to purge all air. Then find the bleed valve on the high-pressure fuel pump and repeat the process. Finally, loosen the nut at the fuel injector's inlet pipe connection and crank the engine to let diesel spray out. Remember to keep the wrench steady to prevent diesel from splashing onto hot engine components. After bleeding, it's best to let the engine idle for ten minutes while observing if the pressure gauge stabilizes.
