GrandPrix (GP-7 Series) Two-Post Lifts 46 P/N 5900209 — August 2018 — Rev. C2
Lubricating
The lift works better and longer if you keep it lubricated. Lubricate the following:
• Cable sheave pins, with WD-40 or equivalent.
• Safety pins, with WD-40 or equivalent.
• The four inside corners of both posts, with light axle grease.
Bleeding the Hydraulic Cylinder
Bleeding the Hydraulic Cylinder removes excess air from the cylinder. Air in the 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 any
excess air will get worked out of the system.
To bleed the Hydraulic Cylinder:
1. Raise and lower the lift four or five times;
wait 30 seconds between each cycle .
Refer to Operation for raising and lower instructions.
2. Check the fluid level in the reservoir; it may be down as a result of using the Hydraulic System.
Add more fluid if necessary. The lift must be fully lowered before changing or adding 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.
Final Checklist Before Operation
Make sure these things have been done before using your lift:
• Review the Installation Checklist to make sure all steps have been performed.
• Make sure the Power Unit is getting power from the power source.
• Check the Power Unit’s Hydraulic Fluid reservoir; it must be full of approved Hydraulic Fluid or
automatic transmission fluid. You can harm the motor by running it without enough fluid.
• Check the Hydraulic System for leaks.
• Make sure both posts are properly shimmed and stable.
• Check to see that all Anchor Bolts are correctly torqued.
• Apply light axle grease to the inside of the posts where the slide blocks move.
• Make sure all cables are properly positioned in their sheaves.
• Make sure all cable sheave retaining pins and/or clips are secure.
• Make sure that all safety locks are cleared and free.
• Make sure the Installation and Operation Manual is available for all operators.
• Perform an operational test of the lift with a typical vehicle.
During the operational test, observe all operating components and check for proper installation and
operation. Do not raise any additional vehicles until a thorough operational check has been
performed with a typical vehicle.
