26 O.S. Walker Inc., NEO Permanent Lifting Magnets
Flat workpieces only!
Do not lift plate’s thinner than indicated in the table!
OPERATING INSTRUCTIONS
Before every lift: Check surfaces of magnet and load. These must be clean, smooth, fl at, free of rust and any
foreign particles!
IMPORTANT!
During handling the stopper must sit tight against the edge of the workpiece at all times. The sliding force
must be counteracted by the stopper. Therefore the lifting magnet should always be placed off the center of
gravity of the workpiece in order for the workpiece to create a torque forcing itself against the stopper.
1. Place the magnet on the load and push the stopper fi rmly against the future lower edge of the load.
2. Adjust the position of the magnet according to the size of the load so that it is slightly off center and
below the center of gravity. (See Figure 5) when the plate is in vertical position. Make sure the lock-
ing pin on the slider is engaged in the hole on the arm.
3. Make sure the stopper remains pressed against the edge of the load! Push the stopper against the
edge of the load again if required.
4. Switch the magnet ON; the lever must lock in place.
5. Stand clear of the device and lift the workpiece a few inches.
6. Jar the workpiece fi rmly to make sure adequate holding force is available.
7. Now slowly lift up to the vertical position, but beware that the arm does not “overshoot” the 90° angle.
If necessary correct the vertical angle by means of the position of the lifting eye.
8. Move the load carefully and smoothly. Avoid shocks and collisions and ALWAYS STAY CLEAR OF
THE LOAD.
9. The load must remain vertical during transport to avoid the load from sliding away from the stopper.
10. Set down and secure. Only now switch OFF the magnet, the lever must lock in place.
