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 qualified 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.

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 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, remove the oil filler screw. Check oil level. Proper oil level should be just below the rim of the opening. Reinstall the oil filler 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 filler screw. This will help release any pressurized air which may be trapped within the reservoir. Reinstall the oil filler screw.

OPERATION

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 firm 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 specified 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.

Lowering

! 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.
