A Checklist for Properly Maintaining a Propane-Powered Forklift
Using forklift propane to power a forklift certainly simplifies things, but it doesn’t entirely remove you from all responsibility.
Caring for your forklift that is powered with forklift propane should entail both a visual and functional inspection at the beginning of every working shift.
Following the below maintenance steps is key to your safety, as well as your equipment’s performance and longevity.
- Examine your forklift’s propane tank: Your forklift propane will be in a portable propane tank, otherwise known as a cylinder. Before your forklift is even turned on, a thorough inspection should be conducted on this tank to look for severe rust, dents and other visible damage. If you notice any damage, swap that tank out for a new one.
- Inspect the pressure relief valve: The pressure relief valve on your installed tank should be in the “up” position, which is equivalent to the 12 o’clock position on a clock. When in this position, the tank will release vapor propane as opposed to liquid propane if the valve activates. You also want to make sure that the pressure relief valve is clean and that its dust cap is securely in place.
- Check your connection points: You can help avoid a fuel leak by regularly checking the connection point between the fuel line and the cylinder. If this isn’t tightly sealed, do not use your forklift until this is resolved. You also want to make sure the O-rings aren’t cracked, dried or missing any components.
- Make sure there are no fuel leaks: It is easy to detect a leak when you’re using propane. In its natural state, the fuel is odorless, but a chemical is added to it during the production process to make it smell like rotten eggs in the event of a leak. If you smell a potential leak or hear any hissing noises near your cylinder or fuel lines, close the service valve and ventilate the area immediately.
- Tighten the bracket and clamps: You want to make sure that the toggle clamps and locating pin on your forklift’s bracket are secure before turning your engine on. If these components are not secure, a propane cylinder can rotate during operation. This is less than ideal, as it puts stress on the hose and can cause the liquid withdrawal tube inside the tank to move out of the liquid fuel, which can make your engine stall.
