SAFETY INSTRUCTIONS 

WAYS TO AVOID A REDUCTION  OF LIFTING CAPACITY 

ADANGER 

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" (51 mm) thick.

The load must be low carbon steel such as SAE 1020.

The magnet's lifting surface must stay level and the contact­
ing surface of the load remain flat.

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 0. S.

Walker Co. or a Qualified Person.*

If you have any difficulty lifting a load,  DON'T LIFT IT! Call
O.S. Walker for advice at 1-800-962-4638.

ADDITIONAL WARNINGS 

A WARNING 

Never lift loads with any dimension greater than

those shown in the LIFTING GUIDELINES.

Never leave the I.R. Remote unit where it may be

damaged.

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.

A WARNING 

Disassembly or repair of this magnet can result in

reduced holding power and/or cause an unsafe

condition. Therefore, anytime the magnet is

disassembled beyond the parts list shown in this

manual, the magnet must be re-tested for break­

away force in accordance with the test described

in ANSI/ASME B30.20.

Modification of any operating mechanism or

structure of this magnet can reduce the magnet's

effectiveness and/or cause an unsafe condition.

Repair or modification of this magnet should only

be done by O.S. Walker*.

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 specific replacement parts listed in this manual and is able to verify the proper functioning

of the specific replacement parts and the entire product after the completion of the installation.
