PREPARATION
Assembly (see Replacement Parts pages 6~9 for reference to parts location & assembly sequence)
Assemble, align and insert the handle assembly & handle position bar into the handle sleeve, then tighten the bolt
on handle sleeve to prevent accidental removal of handle while in use.
Before Use
1. Verify that the product and application are compatible, if in doubt call Omega Technical 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 knob):
a. Clockwise until rm resistance is felt to further turning. This is the ‘CLOSED’ release valve position used to
raise the load.
b. Counter-clockwise, but no more than 1 full turn from the closed position. This is the ‘OPEN’ release valve
position used to lower the load. The more you turn the release valve counter-clockwise, the faster the load
descends.
4. With ram fully lowered, remove the oil ller screw. Check oil level. Proper oil level should be just below the rim of
the opening. Reinstall the oil ller screw.
5. Pour a teaspoon of good quality air tool lubricant into the air supply inlet of the lift control valve. Connect to air
supply, then squeeze the lift control valve for 3 seconds to evenly distribute lubricant.
Note: These models are equipped with the popular 1/4" NPT air coupler. When installing a different air coupler of
your choice, ensure that thread tape or compound is used when servicing connections. To ensure dependable,
trouble free operation an inline air dryer and oiler is recommended.
6. Ensure that jack rolls freely. Raise and lower the unloaded ram throughout the lifting range before putting into
service to ensure the jack 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.) and with ram fully lowered, locate and remove the oil ller screw.
This will help release any pressurized air which may be trapped within the reservoir. Reinstall the oil ller screw.
SAFETY and GENERAL INFORMATION
Save these instructions. For your safety, read, understand, and follow the information provided with and on this jack
before using. The owner and operator of this equipment shall have an understanding of this jack and safe operating
procedures before attempting to use. The owner and operator shall be aware that use and repair of this product
may require special skills and knowledge. Instructions and safety information shall be conveyed in the operator's
native language before use of this jack is authorized. If any doubt exists as to the safe and proper use of this jack,
remove from service immediately.
Inspect before each use. Do not use if broken, bent, cracked or damaged parts are noted. Any jack that appears
damaged in any way, or operates abnormally shall be removed from service immediately. If the jack has been or
suspected to have been subjected to a shock load (a load dropped suddenly, unexpectedly upon it), immediately
discontinue use until jack has been checked by a factory authorized service center (contact distributor or manufacturer
for list of authorized service centers). It is recommended that an annual inspection be done by qualied personnel.
Labels and Operator's Manuals are available from manufacturer.

PRODUCT DESCRIPTION
These Hydraulic Truck Jacks are designed to lift, but not support, rated capacity partial vehicle loads consisting
of one end of a vehicle. Immediately after lifting, loads must be supported by a pair of appropriately rated jack
stands.
NEVER use a hydraulic truck jack as a stand-alone device. After lifting, immediately support
the lifted vehicle with a pair of appropriately rated jack stands.

!
Be sure all tools and personnel are clear before lowering load. Slowly open the release valve! The
more you turn the handle knob counter-clockwise, the faster the load will come down. Maintain control
of the rate of speed at which the load lowers at all times!
1. Raise load high enough to clear the jack stands.
2. Remove jack stands carefully (always used in pairs).
3. Slowly turn handle knob counter-clockwise, but no more than 1 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 vehicle.
4. After removing jack from under the vehicle, fully retract the jack to reduce ram exposure to rust and
contamination.

!
!WARNING
• Study, understand, and follow all printed
materials provided with/on this product before use.
• Do not exceed rated capacity.
• This is a lifting device only!
• Immediately after lifting, support the load with
a pair of appropriately rated jack stands.
• Use only on hard, level surface.
• Lift only on areas of the vehicle as specied by
the vehicle manufacturer.
• Never wire, clamp or otherwise disable the lift
control valve to function by other than operator's
hand.
• No alterations shall be made to this product.
• Failure to heed these markings may result in
personal injury and/or property damage.
To avoid crushing and related injuries:
• Never work on, under or around a load supported
only by hydraulic jack.
• Always use adequately rated jack stands.
• Chock each unlifted tire in both directions.
• Do not use this device to lift, level, lower, support nor
move a house, mobile home, travel trailer, camper or
any building structure.
• Be alert and sober when using this product. Do not
operate under the inuence of drugs or alcohol.
!WARNING
X
!The wheels provided with this jack are for positioning the jack under a load ONLY! The wheels are
not load wheels. Do not try to dolly or move the vehicle with the jack!
OPERATION (see Fig 1)
Lifting
Note: The jack is equipped with handle position lock. To adjust the handle, release lock device by pulling the lever
up, lever is spring loaded and will lock into desired position. Ensure lever locking mechanism is fully engaged before
leaving
1. Connect adequate air source to the air supply inlet.
2. 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.
3. Close the release valve by turning the handle knob clockwise until rm resistance is felt.
4. Center jack saddle under lift point, then squeeze the lift control valve until saddle contacts the lift point. To lift,
continue squeezing the lift control valve until load reaches desired height. Simply release your grip on the lift
control valve to end lift event.
5. Transfer the load immediately to appropriately rated jack stands.
Only attachments and/or adapters supplied by the manufacturer shall be used. Lift only on area of the
vehicle as specied by the vehicle manufacturer.
NEVER use hydraulic jack as a stand alone device! ALWAYS transfer the lifted load IMMEDIATELY to
a pair of appropriately rated jack stands. Use one pair of jack stands per vehicle. Rated capacity is per
pair only! Do not exceed rated capacity.

MAINTENANCE
Important: Use only good grade 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. We recommend Mobil DTE 13M or equivalent.
Adding/ Changing Oil
For best performance and longest life, replace the complete uid supply at least once per year.
1. With saddle fully lowered remove cover plate, then oil ller plug.
2. Lay jack on its side and drain uid into a suitable container.
Note: Dispose of hydraulic uid in accordance with local regulations.
3. Set jack in its upright, level position.
4. Fill with oil. Proper oil level is just below the rim of the opening. Reinstall the oil ller screw.
Lubrication
A periodic coating of light lubricating oil to pivot points, axles and hinges will help to prevent rust and assure that
wheels move freely and the pump functions smoothly. To help ensure trouble free operation, an inline air dryer and
oiler is recommended.
Cleaning
Periodically check the ram for signs of rust or corrosion. Clean as needed and wipe with an oily cloth.
Note: Never use sandpaper or abrasive material on ram surfaces!
Storage
When not in use, store the jack with saddle fully lowered.
