D4-9 / D4-9X Four-Post Lifts 8 P/N 5900251 — Rev. A— October 2020
The main components of your Lift include:
• Power Post. The Post that holds the Power Unit. The Power Post can only be at the Driver-Side
Front or the Passenger-Side Rear of the Lift.
• The other three Posts. The locations of the Safety Lock Holes are different from each other.
Make sure to orient them correctly.
• Power Unit. An electric/hydraulic unit that connects to an electric power source and then
provides Hydraulic Fluid to the Hydraulic Cylinder that raises and lowers the Runways.
• Powerside Runway. The Runway next to the Power Post. The Powerside Runway has the
Hydraulic Cylinder and the Lifting Cables under it.
• Offside Runway. The other Runway. It does
not have a Hydraulic Cylinder or Lifting Cables
under it.
• Utility Rails. Part of each Runway, they hold the Drip Trays and Bottle-Jack Trays. Utility Rails
must be positioned on the inside of the Lift.
• Crosstubes. They connect the two Posts at the Front of the Lift together and connect the two
Posts at the Rear of the Lift together.
• Ramps. One for each Runway. Use them to drive onto and off of the Runways.
• Safety Locks. Once engaged, they hold the Runways up, even if the power goes out or there is
a leak in the Hydraulic Hoses.
Only leave your Lift either fully lowered or engaged on
Safety Locks.
• Tire Stops. Located at the Front of the Lift, Tire Stops prevent the Vehicle’s front Tires from
going any further forward.
• Caster Kit. Gets the bases of the Posts up off the ground so that the entire Lift can be moved. If
you plan on using the Caster Kit, do not anchor the Lift.
• Drip Trays. Position them between the two Runways to catch dripping oil.
• Tire Chocks. When put in place behind a Vehicle’s Tires, they prevent the Vehicle from moving
backwards.
