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 21032, 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.

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 and release valve fully 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 instruction below.

5. For Air Operated models 21032, 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.

NOTICE: Air Operated 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 in-line 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 (Step 3b. above) 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. 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.

! WARNING

• Study, understand, and follow all

before operating this device.

• Do not exceed rated capacity.

• Use only on hard, level surface.

• Lifting device only. Immediately after lifting,

support the vehicle with appropriate means.

• Do not move or dolly the vehicle while on the

jack.

• Lift only on areas of the vehicle as specied by

the vehicle manufacturer.

• No alterations shall be made to this product.

instructions

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

• Failure to heed these markings may result in

personal injury and/or property damage.

OPERATION

Lifting

WARNING: 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.

NOTICE: These jacks are equipped with handle position locks. 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 21032, 22041C, 22051C & 22101C) until load reaches desired height. Never use foot pedal to
raise load.

WARNING: Do not wire, clamp or otherwise disable the lift control valve to function by other than operator's

!

hand.

5. Transfer the load to appropriately rated jack stands.

Lowering

WARNING: Clear all tools and personnel before lowering load. Open the release valve slowly. The further the

!

release valve knob 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 the jack stands.

2. Remove jack stands.

3. 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. Remove jack from under vehicle and fully lower the saddle to reduce ram exposure to rust and contamination.

MAINTENANCE

NOTICE: Use 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 failure of the jack and the potential for sudden

and immediate loss of load. Premium quality hydraulic jack oil is recommended.

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, completely replace 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.

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 the oil ller plug/screw.

4

Lubrication

A periodic coating of light lubricating oil to pivot points and hinges, and applying grease to the lift arm and wheel

ttings, will help to prevent rust and assure that wheels, casters and pump assemblies move freely. To help ensure

trouble free operation, an in-line 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.

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.
