!

lifted vehicle with appropriately rated jack stands. Never place any portion of your body under the vehicle when
lifting or lowering.

PREPARATION

Assembly (ref. Fig. 1, 2)

1. Assemble the 2-piece handle with provided bolt.

2. Insert handle into the handle socket. Tighten the bolt on handle socket to prevent accidental removal of handle
while in use.

WARNING: Do not lift or carry jack by the Pump Handle. Pump Handle could dislodge and jack fall, resulting

!

in possible injury or property damage.

Before Use

1. Before using this product, read the operator's manual completely and familiarize yourself thoroughly with the
product and its components, and recognize the hazards associated with its use.

2. Verify that the product and application are compatible, if in doubt contact Omega Tech Service [phone].

3. To familiarize yourself with basic operation, locate and turn the release valve (pump handle):

a. Clockwise until rm resistance is felt to further turning. This is the ‘CLOSED’ release valve position used to

raise the saddle.

b. Counter-clockwise, but no more than 1/2 turn from the closed position. This is the ‘OPEN’ release valve position

used to lower the saddle.

4. With saddle fully lowered and release valve closed, pump the handle. If lift arm responds immediately, jack is
ready for use. If jack does not respond, follow Bleeding/Venting Trapped Air instruction below.

5. Ensure that jack rolls freely. Raise and lower the unloaded saddle throughout the entire lifting range before putting
into service to ensure the pump operates smoothly. Replace worn or damaged parts and assemblies with Omega
authorized replacement parts only.

Bleeding/Venting Trapped Air

With the release valve in the OPEN position (Step 3b. above) and with saddle fully lowered, locate and remove the

oil ller plug. Pump handle 6 to 8 full strokes. This will help release pressurized air which may be trapped within the
reservoir. Reinstall the oil ller plug and check operation.

OPERATION

Lifting

WARNING: Only attachments and/or adapters supplied by the manufacturer shall be used.

!

1. Follow the vehicle manufacturer’s recommended guidelines for lifting. Engage the vehicle's emergency brake and

chock each unlifted wheel in both directions to prevent inadvertent movement.

2.

Close the release valve by turning the pump handle clockwise until rm resistance is felt.

3. Refer to the vehicle manufacturer owner’s manual to locate approved lifting points on the vehicle. Center jack

saddle under lift point.

4. Pump handle until saddle contacts lift point. To lift, continue pumping handle until load reaches desired height.

5. Immediately transfer the load to appropriately rated jack stands.

handle is turned counter-clockwise, the faster the load will descend. Maintain control of load at all times.

1. Raise load high enough to clear the jack stands.

2.

Remove jack stands.

3. Slowly turn the handle counter-clockwise, but no more than 1/2 full turn. If the load fails to lower:

a. Use another jack to raise the vehicle high enough to reinstall jack stands.
b. Remove the malfunctioning jack and then the jack stands.
c.

Use the functioning jack to lower the

MAINTENANCE

NOTICE: Use only good quality hydraulic jack oil. Avoid mixing different types of uid and NEVER use brake uid,

turbine oil, transmission uid, motor oil or glycerin. Improper uid can cause premature failure of the jack and the
potential for sudden and immediate loss of load. Premium hydraulic jack oil is recommended.

Adding oil

Correct oil level allows the saddle to reach its advertised maximum height and its advertised minimum height.

NOTICE: Too much oil will prevent saddle from lowering completely. Too little oil will not allow the saddle to raise
completely.

1. With saddle fully lowered set jack in its upright, level position. Remove oil ller plug.

2. Fill until oil nearly covers the inner cylinder as seen from the oil ller hole. Reinstall the oil ller plug.

Changing oil

For best performance and longest life, replace the complete uid supply at least once per year.

1. With saddle fully lowered, remove the oil ller plug.

2. Lay the jack on its side and drain the uid into a suitable container.

NOTICE: Dispose of hydraulic uid in accordance with local environmental regulations.

3. Fill until oil nearly covers the inner cylinder as seen from the oil ller hole. Reinstall the oil ller plug.

4

Lubrication

A periodic coating of light lubricating oil to pivot points, axles and hinges will help to prevent rust and assure that
wheels, casters and pump assemblies move freely.

Cleaning

Periodically check the pump piston and ram for signs of rust or corrosion. Clean as needed and wipe with an oily
cloth.

NOTICE: Do not use sand paper or abrasive material on ram and pump piston surfaces.

Storage

When not in use, store the jack with saddle fully lowered.
