PREPARATION
Assembly
Make sure all parts are present (refer Fig. 1 & 2). If any parts is missing or damage, do not attempt to assemble,
install or operate the product. Contact Customer service.
A. Service Jack:
1. Attach the 2-pc handle with bolt provided on the handle.
2. Secure the assembled handle into handle sleeve with provided bolt. Tighten securely to prevent accidental
removal of handle while in use.
B. Jack Stands:
Tools required: Hammer and Punch (not included)
1. Install ratchet bar into base frame with ratchet portion of bar aligned with locking pawl.
2. Move the ratchet bar to its lowest position by raising the locking handle, thereby releasing the stopper and
guiding the bar downward.
3. Ratchet/ collar lock is accomplished by simply pressing the press tab (see Fig. 2) inward using a suitable hammer
and punch. This will effectively prevent inadvertent loss of the ratchet bar.
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. Inspect before each use. Do not use if there are bent, broken or cracked components noted.
4. Always check the vehicle owner’s or service manual for location of proper lift and support points.
Service Jack:
5. To familiarize yourself with basic operation of service jack, locate and turn the release valve (handle):
a. Clockwise until firm 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.
6. With saddle fully lowered, 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. Check oil level. Proper oil level will vary from just covering the ram
cylinder to 3/16” above it as seen from the oil filler hole. Reinstall the oil filler screw.
7. 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 of a Service Jack
With the release valve in the OPEN position (5b.) and with saddle 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.
