PRODUCT DESCRIPTION
This Hydraulic Service Jack is designed to lift, but not support, one end of a vehicle. Immediately after lifting, loads
must be supported by a pair of appropriately rated jack stands.
WARNING: Never use a hydraulic jack as a stand-alone device. After lifting, immediately support the lifted
vehicle with a pair of appropriately rated jack stands.

PREPARATION
Assembly
1. Assemble the two-piece handle with provided bolt.
2. Insert handle into the handle fork. Tighten the bolt on handle fork to prevent accidental removal of handle while
in use.
WARNING: Do not lift or carry jack by handle. Handle could dislodge and jack fall, resulting in possible injury
or property damage.
Before Use
1. Verify that the product and application are compatible, if in doubt call Omega Tech Service [phone].
2. Before using this product, read the operator's manual completely and familiarize yourself thoroughly with the
product, its components and recognize the hazards associated with its use.
3. To familiarize yourself with basic operation, locate and turn the release valve (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 operating handle. If lift arm responds immediately,
jack is ready for use. If jack does not respond, follow Bleeding/Venting Trapped Air procedure below.
5. Ensure that jack rolls freely. Raise and lower the unloaded saddle throughout the 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 (3b above) and Saddle fully lowered, locate and remove the Oil Filler
Plug/Screw. Pump Handle 6 to 8 full strokes. This will help release any pressurized air which may be trapped within
the reservoir. Check oil level and reinstall Oil Filler Plug/Screw.

OPERATION
Lifting
1. Follow the vehicle manufacturer’s recommended guidelines for lifting. Engage the emergency brake and chock
each unlifted wheel in both directions to prevent inadvertent vehicle movement.
2. Close the release valve by turning the 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 to contact lift point. To lift, continue pumping until load reaches desired height.
5. Transfer the load immediately to appropriately rated jack stands.
Lowering
WARNING: Clear all tools and personnel before lowering load. Open release valve slowly. The further handle
is turned counter-clockwise, the faster the load will descend. Maintain control of the load at all times.
1. Raise load high enough to clear 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 a functioning 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 vehicle.
4. After removing jack from under the vehicle, lower lifting arm completely to reduce ram exposure to rust and
contamination.
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
1. With saddle fully lowered set jack in its upright, level position. Remove vent screw.
2. Fill with oil until ~3/16" above the inner cylinder as seen from the oil ller hole. Reinstall vent screw.
Changing oil
For best performance and longest life, replace the complete uid supply at least once per year.
1. With saddle fully lowered, remove vent screw.
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 with oil until ~3/16" above the inner cylinder as seen from the oil ller hole. Reinstall vent screw.
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. Lubricate lift arm through grease ttings.
Cleaning
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 sandpaper or abrasive material on ram and pump piston surfaces.
Storage
When not in use, store the jack with saddle fully lowered.
