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 (888) 332-6419.  
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 firm 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 filler 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 filler hole. Reinstall the  
oil filler 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 filler 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 filler plug/screw.

! WARNING  
! WARNING  
Study, understand, and follow all printed  
materials provided with/on this product before use.  
X
Do not exceed rated capacity.  
• Use only on hard, level surface.  
This is a lifting device only!  
To avoid crushing and related injuries:  
Never work on, under or around a load supported  
only by hydraulic jack.  
Immediately after lifting, support the load with  
a pair of appropriately rated jack stands.  
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 influence of drugs or alcohol.  
• Lift only on areas of the vehicle as specified 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.  
OPERATION  
Lifting  
Only attachments and/or adapters supplied by the manufacturer shall be used. Lift only on area of the  
vehicle as specified 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 firm 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.

Lubrication  
MAINTENANCE  
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.  
Important: Use ONLY good grade hydraulic jack oil.  
Avoid mixing different types of fluid and Never use  
brake fluid, turbine oil, transmission fluid, motor oil or  
glycerin. Improper fluid can cause failure of the jack and  
the potential for sudden and immediate loss of load. We  
recommend Mobil DTE 13M.  
Cleaning  
Periodically check the pump piston and ram for signs  
of rust or corrosion. Clean as needed and wipe with  
an oily cloth.  
Adding oil  
1. With saddle fully lowered set jack in its upright, level  
position. Locate and remove oil filler plug/screw.  
2. Fill with oil until ~3/16" above the inner cylinder as  
seen from the oil filler hole. Reinstall the oil filler  
plug/screw.  
Note: Never use sandpaper or abrasive material on  
these surfaces!  
Storage  
Changing oil  
When not in use, store the jack with saddle fully  
For best performance, replace the complete fluid supply  
at least once per year.  
lowered.  
1. With saddle fully lowered, remove the oil filler plug/  
screw.  
2. Lay the jack on its side and drain the fluid into a  
suitable container.  
REPLACEMENT PARTS
