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 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, locate and remove cover plate, then 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. Check oil level. 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.
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 ller 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 ller plug/screw.
