Important Safety Information

This document has been printed from SPI². Not for Resale

Most accidents that involve product operation, maintenance and repair are caused by failure to
observe basic safety rules or precautions. An accident can often be avoided by recognizing potentially
hazardous situations before an accident occurs. A person must be alert to potential hazards. This
person should also have the necessary training, skills and tools to perform these functions properly.

Improper operation, lubrication, maintenance or repair of this product can be dangerous and
could result in injury or death.

Do not operate or perform any lubrication, maintenance or repair on this product, until you have
read and understood the operation, lubrication, maintenance and repair information.

Safety precautions and warnings are provided in this manual and on the product. If these hazard
warnings are not heeded, bodily injury or death could occur to you or to other persons.

The hazards are identified by the “Safety Alert Symbol” and followed by a “Signal Word” such as
“DANGER”, “WARNING” or “CAUTION”. The Safety Alert “WARNING” label is shown below.

The meaning of this safety alert symbol is as follows:

Attention! Become Alert! Your Safety is Involved.

The message that appears under the warning explains the hazard and can be either written or
pictorially presented.

Operations that may cause product damage are identified by “NOTICE” labels on the product and in
this publication.

Perkins cannot anticipate every possible circumstance that might involve a potential hazard. The
warnings in this publication and on the product are, therefore, not all inclusive. If a tool, procedure,
work method or operating technique that is not specifically recommended by Perkins is used,
you must satisfy yourself that it is safe for you and for others. You should also ensure that the
product will not be damaged or be made unsafe by the operation, lubrication, maintenance or
repair procedures that you choose.

The information, specifications, and illustrations in this publication are on the basis of information that
was available at the time that the publication was written. The specifications, torques, pressures,
measurements, adjustments, illustrations, and other items can change at any time. These changes can
affect the service that is given to the product. Obtain the complete and most current information before
you start any job. Perkins dealers or Perkins distributors have the most current information available.

When replacement parts are required for this
product Perkins recommends using Perkins

replacement parts.

Failure to heed this warning can lead to prema­ture failures, product damage, personal injury or

death.
