GrandPrix Two-Post Lifts

P/N 5900209 — Rev. D3 — Feb. 2020

Tighten the Gear Ring bolts.

Verify the operation of the Arm restraints by pulling up on the Key Ring of the Arm Restraint Pin.

Pivot the arms back and forth and test the operation of the Arm Restraint Pin in various positions.

Make sure the Lift Arms do not move when a force of approximately 100 pounds or less is applied

laterally to the fully extended arms.

Adjust the Gear Ring on each arm as necessary to ensure smooth operation and solid
engagement of all four Arm Restraint Pin Assemblies with the Arm Restraint Gear Ring.

⚠

WARNING

Each arm restraint assembly must be inspected and adjusted before you use the

Lift each and every time. Do not operate the Lift if any of the four arm restraint

systems are not functioning properly. Replace any broken components or

components with broken teeth with authorized replacement parts only.
