SAFETY INSTRUCTIONS
WAYS TO AVOID A REDUCTION OF LIFTING CAPACITY
SAFETY PERSON
O.S. Walker recommends that a person be assigned to review all magnetic
handling applications for these magnets to ensure that safe practices and
procedures are being followed.
*Walker replacement parts may be installed by a **Designated Person.
** Designated Person - A person selected or assigned by the employer as being competent to
replace specic replacement parts listed in this manual and is able to verify the proper functioning
of the specic replacement parts and the entire product after the completion of the installation.
ADDITIONAL WARNINGS
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, at 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 1.0" (24.5 mm) thick for CER-5, 1.5” (38.1 mm) for CER-
7, 2” (51 mm) for models CER-9 through 12 and at least 2.5” (63 mm) for models
CER-16 and 20.
The load must be low carbon steel such as SAE 1020.
The magnet’s lifting surface must stay level and the contacting surface of the load
remain at.
The temperature of the magnet and/or the load must not be greater than 110°F
(43°C).
Repair of this magnet should only be done by the O. S. Walker Co. or a Qualied
Person.*
Do not exceed the magnet duty cycle. Exceeding the duty cycle will result in
reduced lifting capacity.
If you have any difculty lifting a load, DON’T LIFT IT! Call O. S. Walker for advice
at 1-800-962-4638.
WARNING
WARNING
Never lift loads with any dimension greater than
those shown in the LIFTING GUIDELINES.
Never operate damaged or malfunctioning mag-
nets.
Never remove or damage Operating and Warning
labels.
Persons using pacemakers or other medical de-
vices should not use this magnet until they have
consulted with their physician.
If your magnet was provided with a remote
control unit, NEVER place the control unit in a
position where the switch could be accidentally
turned to “OFF”, “DROP”, OR “LIFT”.
Disassembly or repair of this magnet can result in
reduced holding power and/or cause an unsafe
condition. Therefore, anytime the magnet is disas-
sembled beyond the parts list shown in this manual,
the magnet must be re-tested for breakaway force
in accordance with the test described in ANSI/
ASME B30.20.
Modication of any operating mechanism or
structure of this magnet can reduce the magnet’s
effectiveness and/or cause an unsafe condition.
Repair or modication of this magnet should only be
done by O.S. Walker*.
