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 floor.

3. Do not use the jack to raise all four wheels of the forklift from the

floor. Two wheels of the lift must remain in contact with the floor

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 floor, 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.

3. To familiarize yourself with basic operation, locate and turn the release valve knob:

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.

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 filler 

plug. Pump 6 to 8 full strokes. This will help release any pressurized air which may be trapped within the reservoir. 

Reinstall the oil filler plug.

Safety Information

1.

The jack is used to lift from the side of the forklift. However, two wheels of the lift must remain firmly on the

floor.

2. Use extreme caution when lifting narrow forklift (less than 40" wide) from the sides. Always make sure that the

height between the floor and the bottom of the raised tire is never more than one fourth (1/4th) of the vehicle's tread

width. See figure 3. (tread width is measured from centerline to centerline of the tire treads.) If the one fourth figure
