and recognize the hazards associated with its use.
3. To familiarize yourself with basic operation, locate and turn the release valve 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 and release valve closed, pump the operating handle. If lift arm 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. For air option model 28047, 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. 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.
Safety Information
1. The jack is used to lift from the side of the forklift. However, two wheels of the lift must remain rmly on the
oor.
2. Use extreme caution when lifting narrow forklift (less than 40" wide) from the sides. Always make sure that the
height between the oor and the bottom of the raised tire is never more than one fourth (1/4th) of the vehicle's tread
width. See gure 3. (tread width is measured from centerline to centerline of the tire treads.) If the one fourth gure
is exceeded, the forklift could reach the point of instability and tip
over or the angularity of the forklift frame could cause the jack to
kick out and drop the load. Example: If tread width = 36", then never
lift the bottom of the vehicle tire more than 9" off the oor.
3. Do not use the jack to raise all four wheels of the forklift from the
oor. Two wheels of the lift must remain in contact with the oor
at all times.
4. Do not use any kind of "cribbing" under the jack, or on top of the
lift pad area. The jack must always remain in direct contact with
the oor, and the lifting pad or notch must be in direct contact with
the fork lift.
5.
The jack is designed solely for the lifting of forklift. Use of the jack
for any other purpose constitutes misuse of the jack
