Functions

Operation

Read ENTIRE IMPORTANT SAFETY INFORMATION section at beginning of this manual including all text under subheadings therein before set up or use of this product.

Removing a Transmission

Before every use, check and/or fill Hydraulic Fluid.
Once the vehicle is raised and secured on a lift, clear the area underneath the vehicle of people and tools.
Disconnect one end of the Chain and allow it to hang down.
Move the Transmission Jack underneath the transmission.
Close the Release Valve.
Pump the Handle to raise the Transmission Jack.
Stop just below the transmission and align the Saddle to the Transmission with the Tilt Knobs.
Continue raising the Saddle up to the transmission to determine where you will need to adjust the Supports. All four Supports need to grip and make contact with the transmission.
After determining where they need to be set, loosen the threaded bolts on each Support, and adjust it to the proper setting for the transmission. Tighten the bolts.
Raise the unit again to make contact with the transmission, making sure all of the Supports are in firm contact.
Wrap the Chain securely around the transmission, and hook the Chain to the bracket on the other side of the saddle.
Once it is securely fastened, release the bolts holding the transmission in place.
Make sure the area is clear of people and tools, and verify that the transmission is securely held in place. Then, slowly open the Release Valve to lower the Transmission Jack.
Move the Transmission Jack from under the vehicle and perform your desired maintenance.

Replacing a Transmission

Move the Transmission Jack so that the transmission is lined up properly with its connection points.
Close the Release Valve.
Pump the Handle to gradually raise the Transmission Jack, while guiding it into place.
Secure the transmission into place using its hardware.
Double-check to make sure the transmission is securely installed.
Disconnect one end of the Chain and allow it to hang down.
Clear the area near the Transmission Jack, and slowly open the Release Valve to lower the Jack.
Move the Transmission Jack clear of the vehicle.

Maintenance and Servicing

Procedures not specifically explained in this manual must be performed only by a qualified technician.

WARNING: TO PREVENT SERIOUS INJURY FROM TOOL FAILURE:
Do not use damaged equipment. If abnormal noise or vibration occurs, have the problem corrected before further use.

BEFORE EACH USE, inspect the general condition of the equipment. Check for:
- loose hardware,
- misalignment or binding of moving parts,
- visibly leaking hydraulic fluid,
- cracked or broken parts, and
- any other condition that may affect its safe operation.
Before each use and after the inspection, thoroughly test the Jack for proper operation prior to its actual use. If the Jack appears not to be working properly, follow Bleeding instructions.
Periodically, inject grease into the Zerk fitting on the main platform of the Transmission Jack.
Change the hydraulic oil at least once every three years:
- With the Jack fully lowered, remove the Oil Filler Plug on the side of the Housing.
- Tip the Jack to allow the old hydraulic oil to drain out of the Housing completely, and dispose of the old hydraulic oil in accordance with local regulations.
- With the Jack upright, completely fill the Housing with a high quality hydraulic oil (not included) until the oil just begins to run out of the Oil Fill Hole.
- Open the Release Valve and pump the Handle to bleed air from the system.
- Reinstall the Oil Filler Plug.
Wipe dry with a clean cloth.
Then, store the Jack in a safe, dry location out of reach of children and other non-authorized people.
