How TransportGuard® Ends Oil Dilution in Chore and Rental Equipment Engines



Engine failure and unscheduled maintenance in the portable equipment rental industry can be a frustrating, expensive and all-too-common occurrence. When rental customers forget to shut off the fuel valve before transporting equipment, it can cause oil/fuel dilution — leading to costly maintenance and ultimately engine damage and failure. 

Customers are often focused on the primary task of loading, securing and transporting the heavy equipment and simply forget the final, small step of shutting off the fuel valve. They might overlook it when they are in a hurry to leave the rental yard and get to the jobsite. Or, for many customers, they may not regularly operate the specific type of equipment they are renting and don’t realize that portable equipment requires manually closing the fuel supply to prevent leaks during transport.

Whatever the reason, Vanguard's exclusive TransportGuard® technology is the solution to this everyday problem. It solves the issue of fuel dilution with patented, single-action simplicity.

The Hidden Cost of Transport Neglect

When the operator fails to shut off the fuel supply during transport, fuel can flood the carburetor and seep into the cylinder. From there, it travels past the piston rings, diluting the oil in the crankcase. This can lead to difficult starts or catastrophic engine failure.

The result is costly equipment downtime and repairs, unscheduled oil changes, unnecessary contaminated oil recycling and a damaged equipment reputation. All of these outcomes increase the total cost of ownership and decrease productivity for rental houses and their customers.

The Single-Action Simplicity of TransportGuard

TransportGuard is the patented single-action technology from Vanguard that solves this problem. TransportGuard integrates a single-action fuel and ignition shut-off switch — eliminating the costly, damaging effects of oil/fuel dilution during transport.

It works using a user-friendly 3-in-1 control lever that manages the engine’s throttle, ignition and fuel supply. This simplicity is the key. The operator doesn't have to remember a separate step for shutting off the fuel supply, which eliminates human error. The moment the user moves the lever to the “off” position to stop the engine, fuel is immediately blocked from reaching the carburetor.
