Change a Propane Tank
Propane powered forklifts are frequently used in warehouses. The forklift is made with the propane tank mounted at the back of the driver. The tanks, which look much like beer kegs, need to be replaced periodically as they have a limited lifespan. Operators of forklifts should use care when handling propane tanks. Compressed gases are very hazardous, specially because the gas is flammable. Use caution when replacing and removing propane tank to avoid injury.
1 If there is a need to replace the propane tank, the first step is to stop the forklift, then turn the tank valve off. The lift truck should be left on until the engine dies. This procedure burns the gas off inside the transfer hose which connects the tank and the engine. Before taking the next steps, wear the proper safety equipment, such as insulated gloves made of either leather or neoprene. It is really important for you to protect your skin from touching the compressed gas, that is extremely cold.
2 The hose of the tank has to be disconnected, followed by removing the tank from its holding straps. When you put in a new tank, tighten the nut to reconnect the holding straps and to reconnect the hose at the valve of the tank.
3 Leaks can be checked simply by applying soapy water to the valve and slightly opening it. If there is a leak, it will cause bubbles to froth from around the valve. If this happens, check the connection hose at the nut and the valve area. Re-tighten the connecting nut if you detect any leaks in the area of the valve, and afterward do the leak checking process once more. Persistent leaks mean that both the nut and connecting hose would have to be replaced. Then again, if replacing the hose and nut still does not stop the leak, the tank must be replaced.
4 Lastly, open the valve all the way to enable the gas to fill the connecting hose. Then you could start the lift truck and resume working.
