(2) 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.

Figure 2

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, 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. Ensure oil level is just below the oil filler hole. Reinstall oil filler plug.

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 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.

Lift only on areas of the forklift as specified by the forklift manufacturer.

OPeRATIOn

Lifting

!

Ensure hydraulic unit does not contact vehicle during lift event.

1. Follow the vehicle manufacturer’s recommended guidelines for lifting. Engage the emergency brake and chock each unlifted wheel in both directions to prevent inadvertent vehicle movement.

2. Close the release valve by turning it clockwise until firm resistance is felt.

4. Verify lift point, center jack saddle under lift point.

5. Squeeze the lift control valve (model BH6047 only) or insert handle into handle sleeve and pump to contact lift point. To lift, continue pumping until load reaches desired height.

nOTe: for model BH6047, DO NOT operate by air and by hand pumping at the same time.

5. Transfer the load immediately to appropriately rated forklift stands.

!

ALWAYS transfer the lifted forklift

IMMEDIATELY to a pair of appropriately rated forklift stands. Use one pair of forklift stands per forklift. Rated capacity is per pair only! Do not exceed rated capacity.

4

Lowering

!

lowering load. Slowly open the release valve!

The more you turn the knob counter-clockwise, the faster the load will come down. Maintain control of the rate of speed at which the load lowers at all times!

1. Raise forklift high enough to clear the forklift stands.

2. Remove stands carefully ( always used in pairs).

3. Slowly turn the release valve counter-clockwise, but no more than 1/2 full turn. If the load fails to lower:

a. Use another jack to raise the forklift high enough to reinstall forklift stands.

b. Remove the malfunctioning jack and then the forklift stands.

c. Using the functioning jack to lower the forklift.

4. After removing jack from under the forklift, fully lower the saddle and push handle sleeve down to reduce ram and piston exposure, rust and contamination.

MAInTenAnCe

Important: Use OnLY good grade hydraulic jack oil. Avoid mixing different types of fluid and never use brake fluid, turbine oil, transmission fluid, motor oil or glycerin. Improper fluid can cause failure of the jack and the potential for sudden and immediate loss of load. We recommend Mobil DTE 13M.

Adding oil

1. With saddle fully lowered set jack in its upright, level position. Locate and remove oil filler plug.

2. Fill with oil until just below the rim of oil filler hole. Reinstall the oil filler plug.

Changing oil

For best performance, replace the complete fluid supply at least once per year.

1. With saddle fully lowered, remove oil filler plug.

2. Lay the jack on its side and drain the fluid into a suitable container.

note: Dispose of hydraulic fluid in accordance with local regulations.

3. Fill with oil until just below the rim of oil filler hole. Reinstall the oil filler plug.

Lubrication

1. A periodic coating of light lubricating oil to pivot points will help to prevent rust and assure that pump assemblies move freely.

2. Air pump should be internally lubricated before each use. Use good quality air tool lubricant. If no inline oiler is used, pour a teaspoon of air tool oil into the air control valve inlet. Operate the jack with air pressure to fully distribute the oil inside the air motor.

Cleaning

Periodically check the pump piston and ram for signs of rust or corrosion. Clean as needed and wipe with an oily cloth.

note: Never use sandpaper or abrasive material on these surfaces!

Storage

When not in use, store the jack with saddle fully lowered.
