INTRODUCTION
2 2
Read this manual carefully and learn how to operate and maintain your magnet properly. Failure
to do so could result in serious injury or death to yourself and others in the area of operation.
This manual should be considered a permanent part of your magnet and should always be
available to all operators and remain with the magnet if it is re-sold.
Additional copies of this OPERATOR'S manual ARE AVAILABLE.
JUST CALL 1-800-962-4638 AND REQUEST ADDITIONAL COPIES OF MANUAL #37-DD16630.

UNSAFE LIFTING APPLICATIONS FOR YOUR MAGNET
■Never li any pipe, solid round or struc
tural shapes with this magnet.
■Never li any castings that do not have
a machined flat lifting surface for the
magnet. The location of the liing sur
face should be such to permit the load
to remain level when lifted.

As the length or width of a load increases, it will cease to remain flat when lied as the edges
will begin to droop. This drooping or sagging of the load can create an air gap between the
load and the magnet, especially at the ends of the magnet. This is referred to as peel. If this
occurs, the liing capacity of the magnet is greatly reduced.
For plate liing, where drooping oen occurs, rectangular shaped magnets must be positioned
so that the length of the magnet is parallel to the width of the load.
As the slope of the magnet's liing surface changes from horizontal to vertical, the liing
capacity of the magnet decreases. When the magnet's liing surfaces are vertical, the liing
capacity of the magnet is minimum and dependent upon the coeicient of friction between the
magnet's liing surface and the load.
The full surface of the magnet must contact the load if the magnet is to achieve its rated lift
capacity.
The temperature of the load can cause damage to the magnet and if high enough, can even
change the magnetic characteristics of the load. For Standard Li Magnets, Walker should be
consulted if the load or air temperature exceeds 110° F (43° C).
