How to Change a Propane Tank on a Forklift

Most forklifts used in warehouses are propane powered. The tanks of propane mount behind the driver and are similar in shape to beer kegs. These tanks have a limited operating time and need replacement often. Handling tanks of compressed gases can be dangerous and when the gas is flammable the danger increases. Extreme care is required when these tanks are removed and replaced with fresh ones.

Difficulty: Moderately Easy

Instructions

1. Stop the forklift with the engine still running and turn off the valve on the propane tank. Allow the forklift to continue running until the engine dies. This ensures that no gas is still contained in the transfer hose from the tank to the engine. Make sure you have the proper safety equipment before continuing. You must wear insulated gloves of leather or neoprene to protect yourself from the extreme cold of the compressed gas.

2. Disconnect the hose from the propane tank and remove the holding straps on the tank. Remove the tank and replace with a full tank. Reattach the holding straps. Position the hose at the valve of the tank and tighten the nut.

3. Open the valve slightly and check for leaks with a soapy water solution. If any bubbles form then there is gas leaking. Check the area around the valve, along the connection hose and at the connecting nut itself. If you find any leaks in the region of the valve, use a wrench to tighten the connecting nut more. Recheck for leaks. If you again find leaks, then replace the connecting hose and nut. If this doesn't solve the leak problem replace with another full tank.

4. Undo the valve fully and let the gas fill the connecting hose to the engine. Restart the engine and continue work.
