Change a Propane Tank
Propane fueled forklifts are normally used in warehouses. The forklift is made with the propane tank mounted at the back of the operator. The tanks, which look a lot like beer kegs, have to be replaced every so often as they have a limited lifespan. Forklift drivers should use care when handling propane tanks. Compressed gases are dangerous, specially because the gas is flammable. Use caution when removing and replacing propane tank to avoid being injured.
1 If there is a need to replace the propane tank, the first step is to stop the lift truck, then turn the tank valve off. The forklift must be left on until the engine dies. This process burns the gas off inside the transfer hose that connects the engine and the tank. Before taking the next steps, wear the correct safety equipment, like for instance insulated gloves made of either leather or neoprene. It is very important for you to protect your skin from contact with the compressed gas, which is very cold.
2 Disconnect the hose from the tank and take off the holding straps to remove the tank. When you put in a new tank, reconnect the holding straps and reconnect the hose at the valve of the tank by tightening the nut.
3 Leaks could be inspected just by applying soapy water to the valve and opening it slightly. If there is a leak, it will cause bubbles to froth from around the valve. If this occurs, inspect the valve area and the connection hose at the nut. Re-tighten the connecting nut if you detect any leaks in the valve area, and after that perform the leak inspection procedure again. Persistent leaks mean that the connecting hose and nut should be replaced. Nonetheless, if replacing the nut and hose still does not stop the leak, the tank must be replaced.
4 Finally, open the valve all the way to allow the gas to fill the connecting hose. Then you could start the forklift and continue working.
