PRODUCT DESCRIPTION
Omega Long Chassis Hydraulic Service Jacks are 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. Air actuated function available for
Models 22041C, 22051C & 22101C. Air actuated units require at least 7.8 CFM @ 110 - 175 PSI. A minimum of 150
PSI air pressure is required to raise rated capacity load.
NEVER use hydraulic jack as stand-alone device. After lifting, immediately support the lifted vehicle with
a pair of appropriately rated jack stands.

PREPARATION
Assembly
Always secure the handle into the handle sleeve by means of the bolt lock washer and nut provided. Tighten securely
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, 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 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, locate and remove cover plate, then remove the oil ller plug/screw. Pump 6 to 8 full
strokes. This will help release any pressurized air which may be trapped within the reservoir. Check oil level. Proper
oil level will vary from just covering the ram cylinder to 3/16” above it as seen from the oil ller hole. Reinstall the
oil ller plug/screw.
5. For air option models 22041C, 22051C & 22101C, Pour a teaspoon of good quality, air tool lubricant into the air supply
inlet of the lift control valve. Connect to air supply and operate 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 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.) and with saddle fully lowered, locate and remove the oil ller plug/
screw. Pump 6 to 8 full strokes. This will help release any pressurized air which may be trapped within the reservoir.
Reinstall the oil ller plug/screw.

!WARNING
• Study, understand, and follow all printed
materials provided with/on this product before use.
• Do not exceed rated capacity.
• Use only on hard, level surface.
• This is a lifting device only!
• Immediately after lifting, support the load with
a pair of appropriately rated jack stands.
• 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.
• Do not move or dolly the vehicle while on the jack.
• 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.

OPERATION
Lifting
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.
Note: The jack is equipped with handle position lock. To adjust the handle, release lock device by pulling the lever
up, then back until lever is locked into place.
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. Locate and close the release valve by turning the release valve knob 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. Verify lift point, then pump handle or foot pedal to contact lift point. To lift, pump handle or squeeze lift control valve
(models 22041C, 22051C & 22101C) until load reaches desired height. Never use foot pedal to raise load.
5. Transfer the load immediately to appropriately rated jack stands.
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.
Lowering
Be sure all tools and personnel are clear before lowering load. Slowly open the release valve! The more
you turn the release valve 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 the release valve knob 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 vehicle.
4. After removing jack from under the vehicle, fully lower the saddle to reduce ram exposure to rust and
contamination.

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 failure of the jack and
the potential for sudden and immediate loss of load. We
recommend Mobil DTE 13M.
Adding oil
1. With saddle fully lowered set jack in its upright, level
position. Locate and remove oil ller plug/screw.
2. Fill with oil until ~3/16" above the inner cylinder as
seen from the oil ller hole. Reinstall the oil ller
plug/screw.
Changing oil
For best performance, replace the complete uid supply
at least once per year.
1. With saddle fully lowered, remove the oil ller plug/
screw.
2. Lay the jack on its side and drain the uid into a
suitable container.
Note: Dispose of hydraulic uid in accordance with
local regulations.
3. Fill with oil until ~3/16" above the inner cylinder as
seen from the oil ller hole. Reinstall the oil ller
plug/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.
To help ensure trouble free operation, an inline air dryer
and oiler is recommended.
Cleaning
Periodically check the pump piston and ram for signs
of rust or corrosion. Clean as needed and wipe with
an oily cloth.
Note: Never use sandpaper or abrasive material on
these surfaces!
Storage
When not in use, store the jack with saddle fully
lowered.
