SAFETY INSTRUCTIONS GENERAL SAFETY RULES Danger always exists when loads are transported by lifting devices, especially when the equipment is not being used properly or is poorly maintained. Because accidents and severe bodily injury or death can result, special safety precautions apply to the operation, inspection, and maintenance of the Walker Lift Magnets. Following these simple rules can help to avoid lifting accidents: DANGER Always stay clear of the load.
SAFETY INSTRUCTIONS RECOGNIZE SAFETY INFORMATION This is the safety alert symbol. When you see this symbol on your magnet or in this manual, be alert to the potential for personal injury. Follow recommended precautions and safe operating practices at all times. DANGER This indicates a situation in which a hazard is imminent and will result in a high probability of serious injury or death.
SAFETY INSTRUCTIONS WAYS TO AVOID A REDUCTION OF LIFTING CAPACITY DANGER To Avoid any Reduction of Lifting Capacity: The lifting surfaces of the magnet and the area of the load where the magnet will be located must be clean, smooth, flat and free of nicks and burrs. The full area of the magnet’s lifting surface must be in contact with the load. The load must be at least 2.5" (64 mm) thick. The load must be low carbon steel such as AISI 1020.
IMPORTANT FACTS FOR THE OPERATION OF LIFT MAGNETS LOAD CHARACTERISTICS OTHER THAN JUST WEIGHT MUST BE CONSIDERED IN ORDER TO DETERMINE THE LOAD THAT ANY MAGNET CAN LIFT. This statement is true for all lifting magnets because they all operate using the same fundamental laws of physics. Magnetic power is often pictured as lines of magnetic force flowing from north pole to south pole. Anything that limits the flow of these magnetic lines of force obviously reduces the magnet’s lifting capacity.
3. LOAD ALLOY Low carbon steels, such as AISI 1020 steel, are nearly as good conductors of magnetic lines of force as pure iron. However, many other alloys contain non-magnetic materials, which reduce the ability of magnetic lines of force to flow into the load. An alloy such as AISI 300 series of stainless steel is almost as poor a conductor of magnetic lines of force as air.
SAFETY FOR FAST, EASY LIFTING WITH YOUR WALKER NEO-125, NEO-250, NEO-500, 1 NEVER attempt to operate this lift magnet until you read and understand the OPERATOR’S MANUAL & SAFETY INSTRUCTIONS for the NEO-125, NEO-250, NEO-500, NEO-1000 AND NEO-2000 Lifting Magnets. 5 Check to be sure no one is near the load to be lifted. Inform others in the area that a lift is to begin. Lift the load 2 to 3 inches (50 to 75 mm) and then jar the load to insure that adequate holding power is available.
RULES LIFT MAGNETS MODELS: NEO-1000 & NEO-2000 unless the magnet is in contact with a load of a thickness equal to those listed manual. Attempting to energize or de-energize this magnet without a load or high probability of personal injury due to handle spring back. 3 4 Position the magnet so the load remains level. To energize magnet, grip the handle firmly and pull the handle from its locked position. Turn the handle to the “ON” position.
RECOMMENDED LIFTING PROCEDURES SAFETY HOOK LATCH Always use a safety hook latch on your crane hook to hold your magnets. STAY CLEAR OF THE LOAD Guide the load by pushing or pulling the edges of the load. Keep your entire body clear of the load at all times. PLATE LIFTING On plates less than 1 1/2” (38mm) thick, position the magnet length so that it is parallel to the width of the plate. Never lift any plate less than 1/4” (6mm) thick. (See Important Facts 2 & 4).
GUIDELINES FOR THE REDUCTION OF THE RATED LIFTING CAPACITY : Each Walker magnet model is rated for a different weight limit, and the load characteristics will affect the lifting capacity of the magnets. The lifting guidelines for the various models are shown on the following pages. The Lifting Guidelines charts show the effect of air gap, load thickness, load length, and load width on lifting capacity. As the thickness of the load decreases, so does the rated lifting capacity of the magnet.

INSPECTION AND MAINTENANCE INSTRUCTIONS EVERY LIFT Keep the lifting surfaces of the magnet CLEAN, SMOOTH, FLAT, FREE OF RUST and any FOREIGN MATERIALS. Nicks and burrs on the lifting surfaces will reduce the lifting capacity. If burrs occur, they can be removed by filing or hand stoning them away. However, care must be taken to protect the neighboring lifting surfaces. Check the operation of the handle. The handle shaft should move freely when extended and return promptly upon release.
