Omega Lift Equipment 60120 Manuel Des Consignes D'utilisation Et Des Pièces page 8

• Study, understand, and follow all printed materials provided with/on this product before use.
• Always use an adequately rated, calibrated load cell with digital indicator to monitor pressing force!
• Do not exceed rated capacity.
• Use the device only on a hard, level surface.
• Always wear safety goggles when working on or near this equipment.
• Keep hands, feet and all other body parts away from loading area.
• Never leave loaded press unattended.
• Projectile hazard! Ensure workpiece and any attachment is centrally loaded and a safety shield is installed
around workpiece to help protect against projectiles.
• Do not modify this device beyond installing a shield to protect against projectiles.
• Ensure the user is familiar with the controls and operational characteristics of this product and aware of the
potential hazards associated with its use.
• Failure to heed these markings may result in personal injury and/or property damage.
For Models 60123, 60253 & 65123 ONLY:
• Always install and monitor an in-line, calibrated pressure gauge while operating.
• Always inspect hoses and connections for damage prior to use.
OPERATION
Projectile Hazard! Wear ANSI approved eye protection. Never stand directly in front of loaded press.
!
Ensure that workpiece is center-loaded and secure. Reduce risk of flying debris by carefully following
all operating instructions. Know your press and hazards associated with its use.
Crush Hazard! Keep hands and feet from bed area at all times.
1. Insert the support pins to desired height, then lower the bed. Ensure bed frame is fully rested on the support pins.
2. Place arbor plates on the bed frame as needed.
3. Place workpiece on bed frame, using every precaution necessary to ensure your safety and prevent property
damage. Position workpiece in a manner which will not allow it to inadvertently fall from bed.
4. a.)For Models 60120 & 60200: With notched (or stamped) end of jack handle, close release valve by turning it
clockwise firmly, until tight.
b.) For Models 60123, 60253 & 65123: Close release valve by turning it clockwise firmly, and pump the handle
to extend the ram until ram nears workpiece.
5. Pump until ram nears workpiece.
6. Align ram and workpiece to ensure center-loading.
7. Apply load to workpiece by pumping handle. Do not overload workpiece.
For Models 60123, 60253 & 65123: monitor the pressure gauge and calculate the applied load using the
following formula as basic guideline: Force = Pressure X Area
1. Effective Area of models 60123, 65123= 2.41 in ²
Problem 1: Determine the applied load in lbs. force on a workpeice being pressed by a 60123 whose pressure
gauge is reading 9000 psi.
Solution 1: 9000 X 2.41= 21,690 lbsf
Problem 2: Determine the applied load in lbs. force on a workpeice being pressed by a 60253 whose pressure
gauge is reading 2200 psi.
Solution 2: 2200 X 5.14= 11,308 lbsf
8. Stabilize workpiece in a manner which will not allow it to inadvertently fall from the bed once the load is removed,
then turn release valve counter-clockwise to retract the ram and remove workpiece. Do not turn the release valve
counter-clockwise more a 1 full turn.
Note: To protect your ram, do not continue to operate pump after it is fully extended or retracted.
To reduce the risk of personal injury and/or property damage, ensure that the rated working pressure of
!
each pressurized attachment be equal to or greater than the rated working pressure developed by the
hydraulic pump.
