Set Up

Read the ENTIRE IMPORTANT SAFETY INFORMATION section at the beginning of this

manual including all text under subheadings therein before set up or use of this product.

Removing Shipping Block

CAUTION! The Handle Socket will be held down by a plastic block under tension.

Wear ANSI-approved safety goggles before freeing Handle Socket. Hold Handle Socket down while

removing block. After removal, carefully swing Handle Socket up until tension is released.

A plastic block holds the Handle Socket in position during shipment. This

helps prevents shipping damage. To remove it:

1. Press down on the Handle Socket to

relieve tension on the plastic block.

2. Remove plastic block from the bar.

3. Slowly raise the Handle Socket

until tension is released.

Attaching the Handle

1. Slide the Upper Handle into the Lower Handle.

Line the Button on the Lower Handle up with the

hole in the Upper Handle until it clicks into place.

2. Loosen the Set Screw and insert the grooved end

of the assembled Handle into the Handle Socket.

3. Tighten the Set Screw.

Bleeding Trapped Air

1. With the Jack fully lowered, remove both Screws

on the end of the Cover Plate that is closer to the

Saddle. Swing the Cover Plate open. See Figure A.

2. Remove the Fill Plug on top of the Cylinder.

Check that the oil level inside the Cylinder is

at the top of the Piston. See Figure B.

3. Insert the Handle into the Handle Socket

to operate the Release Valve.

4. Turn the Handle counterclockwise to open the valve.

5. Pump the Handle up and down quickly

10-15 times to force air from the system.

6. Replace the Fill Plug, close the

Cover Plate, and reinstall the Screws. Fill Plug Safety Valve Covers

Do not open or adjust.

Adding Oil

NOTICE: To prevent damage and premature wear,

use only non-detergent 22 weight hydraulic jack oil.

1. With the Jack fully lowered, remove both Screws

on the end of the Cover Plate that is closer to

the Saddle. Swing the Cover Plate open.

2. Remove the Fill Plug on top of the Cylinder.

3. Add non-detergent 22 weight hydraulic jack oil

into the Fill Plug hole slowly until the oil level just

covers the top of the Piston inside the Cylinder.

4. Replace the Fill Plug, close the

Cover Plate, and reinstall the Screws.

Operation

Read the ENTIRE IMPORTANT SAFETY INFORMATION section at the beginning of this

manual including all text under subheadings therein before set up or use of this product.

Lifting

Park vehicle on a flat, level, solid, surface safely away from oncoming traffic. Turn off the vehicle’s engine.

Place the vehicle’s transmission in “PARK” (if automatic) or in its lowest gear (if manual).

Set the vehicle’s emergency brake. Then, chock the wheels that are not being lifted.

1. Turn the Handle counterclockwise to lower the Jack.

Once the Jack is fully lowered, turn the

Handle firmly clockwise to close it.

2. Carefully position the Saddle of the Jack under the

vehicle manufacturer’s recommended lifting point.

(See vehicle manufacturer’s owner’s manual

for location of frame lifting point.)

3. Pump the Handle until the top of the Jack’s Saddle

has nearly reached the vehicle lifting point. Position

the Saddle directly under the vehicle’s lifting point.

4. To lift the vehicle, pump the Handle.

Use smooth, full strokes.

5. Once the vehicle is raised, slide a jack stand of

appropriate capacity (not included) under a proper

lifting point referred to in the vehicle owner’s

manual. Always use two jack stands, position them

at the same point on each side of the vehicle.

WARNING! The rated capacity of jack stands is per

pair, not the individual capacities combined unless

specifically noted on the product by the jack stand

manufacturer. Do not exceed rated jack stand

capacity. Ensure that the vehicle support points

are fully seated in the saddle of both jack stands.

Use a matched pair of jack stands per vehicle to

support one end only. Failure to do so may result

in the load suddenly falling, which may cause

personal serious injury and/or property damage.

6. Center saddle of the jack stand(s) under the vehicle’s

lifting point(s). Set the jack stand(s) to the same

height according to the manufacturer’s instructions,

making sure that they lock securely into position.

7. Slowly turn the Handle counterclockwise to lower

the vehicle onto the saddle(s) of the jack stand(s).

Then, turn the Handle firmly clockwise to close it.

Lowering

1. Carefully remove all tools, parts, etc.

from under the vehicle.

2. Position the Saddle under the lifting point.

Turn the Handle firmly clockwise and raise

load high enough to clear the jack stands,

then carefully remove jack stands.

3. Slowly turn the Handle counterclockwise

(never more than 1/2 full turn) to lower

the vehicle onto the ground.

4. Lower the Jack completely. Then, store in a

safe, dry location out of reach of children.

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 tool. Check for:

• leaking hydraulic oil,

• loose hardware or parts,

• misalignment or binding of moving parts,

• cracked, bent or broken parts, and

• any other condition that may

affect its safe operation.

Thoroughly investigate and correct the causes for

all issues that are found. Do not use Jack until all

issues are understood and properly corrected.

ALSO, BEFORE EACH USE, thoroughly test

the Jack for proper operation prior to actual use.

If the Jack’s motion seems spongy or the

Saddle does not lift completely, follow

Bleeding instructions on page 6.

2. AFTER USE, 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.

NOTICE: Storing the Jack in a humid area or

exposing it to corrosive vapor voids the warranty.

3. Weekly - Jack Lubrication:

a. Lubricate according to the below steps using

only general purpose lithium grease.

b. Inject grease into each of the grease fittings.

c. Lubricate the linkages and pivot points lightly.

Note: Improper or inadequate

lubrication voids the warranty.

4. Change the hydraulic oil at least

once every three years:

a. With the Jack fully lowered, remove both Screws

on the end of the Cover Plate that is closer to

the Saddle. Swing the Cover Plate open.

b. Remove the Fill Plug on the top of the Cylinder.

c. 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.

d. Follow instructions for Adding Oil on page 6.

e. Replace the Fill Plug, close the

Cover Plate, and reinstall the Screws.

f. Follow instructions for

Bleeding Trapped Air on page 6.

Troubleshooting

TO PREVENT SERIOUS INJURY:

Use caution when troubleshooting a malfunctioning jack. Stay well clear of the supported load.

Completely resolve all problems before use. If the solutions presented in the Troubleshooting guide

do not solve the problem, have a qualified technician inspect and repair the jack before use.

After the jack is repaired: Test it carefully without a load by raising and lowering it fully,

checking for proper operation, BEFORE RETURNING THE JACK TO OPERATION.

DO NOT USE A DAMAGED OR MALFUNCTIONING JACK!
