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

1. Before every use, check and/or fill Hydraulic Fluid.

2. Once the vehicle is raised and secured on a lift, clear

and allow it to hang down.

4. Move the Transmission Jack

underneath the transmission.

5. Close the Release Valve.

6. Pump the Handle to raise the Transmission Jack.

7. Stop just below the transmission and align the

Saddle to the Transmission with the Tilt Knobs.

8. 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.

9. 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.

10. Raise the unit again to make contact

with the transmission, making sure all of

the Supports are in firm contact.

11. Wrap the Chain securely around the transmission,

and hook the Chain to the bracket on

the other side of the saddle.

12. Once it is securely fastened, release the

bolts holding the transmission in place.

13. 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.

14. Move the Transmission Jack from under the

vehicle and perform your desired maintenance.

Replacing a Transmission

1. Move the Transmission Jack so that the transmission

is lined up properly with its connection points.

2. Close the Release Valve.

3. Pump the Handle to gradually raise the

Transmission Jack, while guiding it into place.

4. Secure the transmission into

place using its hardware.

5. Double-check to make sure the

transmission is securely installed.

6. Disconnect one end of the Chain

and allow it to hang down.

Maintenance and Servicing

Procedures not specifically explained in this manual must

be performed only by a qualified technician.

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.

1. 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.

2. 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 on page 3.

3. Change the hydraulic oil at least

once every three years:

a. With the Jack fully lowered, remove the

Oil Fill Plug on the side of the Hydraulic Ram.

b. Tip the Jack to allow the old hydraulic oil to

drain out of the Hydraulic Ram completely,

and dispose of the old hydraulic oil in

accordance with local regulations.

c. With the Jack upright, completely fill

the Hydraulic Ram with a high quality

hydraulic oil (not included) until the oil just

begins to run out of the Oil Fill Hole.

d. Open the Release Valve and pump the

Handle to bleed air from the system.

e. Reinstall the Oil Filler Plug.

4. 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.

Troubleshooting

TO PREVENT SERIOUS INJURY: Use caution when troubleshooting malfunctioning jack.

Stay clear of supported load. Completely resolve all problems before use.

If solutions presented in Troubleshooting guide do not solve the problem, have a qualified technician

inspect and repair jack before use. After jack is repaired: Test it carefully without a load by raising and

lowering it fully, checking for proper operation, BEFORE RETURNING JACK TO OPERATION.
