GrandPrix Two-Post Lifts 53 P/N 5900209 — Rev. D3 — Feb. 2020
Lubricating
BendPak recommends lubricating the following locations on the Lift before starting normal operation
and on a monthly basis afterwards, to keep your Lift working better and longer:
• The four inside corners of both Posts (which is where the Slide Blocks slide)
• The pins of the Microswitch Sheave and the Safety Sheaves
We recommend using white lithium grease or light axle grease as the lubricant.
Bleeding the Hydraulic Cylinder
Bleeding the Hydraulic Cylinder removes excess air from the cylinder. Air in the Hydraulic Cylinder can
cause the Lift to move erratically or make odd noises.
The Hydraulic Cylinder is self-bleeding, which means you just have to use the Lift a few times and
excess air will get worked out of the Hydraulic System.
To bleed the Hydraulic Cylinder:
1. Raise and lower the Lift four or five times;
you must wait 30 seconds between each cycle .
Refer to Operation for raising and lowering instructions.
2. Check the Hydraulic Fluid level; it may be down as a result of using the Hydraulic System.
Add more Hydraulic Fluid if necessary. Lift must be fully lowered to change the Hydraulic Fluid.
3. Raise the Lift to full rise and run the motor for approximately three seconds after the Lift stops.
This places pressure on the Hydraulic System.
4. Stop and check all fittings and hose connections; tighten or reseal if required.
5. Lower the Lift back to the ground.
