The 794 AC Off-Highway Trucks utilize the "Fast Fill Service System". The "Fast Fill Service System" is designed to keep dirt and mud from contaminating the fluid systems. The system minimizes fluid loss during disconnection. The control box for the "Fast Fill Service System" is mounted on the left side of the front bumper of the machine. The control box includes five fluid fill ports. The operator or the service personnel will connect the couplings to these ports. Each port corresponds to the eight fluids that are serviced by the system.
- Quick fill cycle
- Reduced chance of spills
- Reduced chance of fluid contamination
- Reduced fuel foaming which results in a full tank and longer engine run time between refueling
- Reduced downtime and increased productivity
- Reduced chance of injury
- Refills at ground level

The fast fill service station is the fill point for the system. The service station has four fill points, and two switches controlling the auto lubrication system. The toggle switch (7) controls the auto lubrication fast fill system. When the auto lubrication tank is full, the push to test / full light (8) will illuminate.
