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.
WARNING: 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.
PREPARATION
Assembly (see Replacement Parts pages 6-10 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
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 firm 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 and release valve closed, pump the operating handle. If ram responds immediately, jack
is ready for use. If jack does not respond, open release valve and pump 6 to 8 full strokes to purge air. Close
release valve and recheck operation.
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 filler 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 screw.
