PREPARATION

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, locate and turn the release valve lever:
a. Clockwise until firm resistance is felt to further turning. This is the 'CLOSED' release valve position used to
raise the ram plunger.
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 ram plunger.
4. With Ram Plunger fully retracted and release valve closed, pump the operating handle. If Ram Plunger responds
immediately, jack is ready for use. If jack does not respond, follow Bleeding/Venting Trapped Air instruction
below.
5. For air option model 44981C:
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 jacks are equipped with the popular 1/4" NPT air coupler. If installing a different air coupler of
your choice, use thread tape or compound when servicing connections. To ensure dependable, trouble free operation
an inline air dryer and oiler is recommended.
6. Check that pump operates smoothly before putting into service. 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 above) and with ram plunger fully lowered, locate and remove
the oil filler plug. Insert the handle into the handle sleeve; then pump 6 to 8 full strokes. This will help release any
pressurized air which may be trapped within the reservoir. Oil level should be even with the bottom of the oil filler
hole. Reinstall the oil filler plug.
