Important Safety Information
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 function 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 other persons.
The hazards are identified by the “Safety Alert Symbol” and followed by a “Signal Word” such as
“WARNING” as 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.
Caterpillar 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
Caterpillar 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 made unsafe by the operation, lubrication,
maintenance or repair procedures you choose.
The information, specifications, and illustrations in this publication are on the basis of information
available at the time it was written. The specifications, torques, pressures, measurements,
adjustments, illustrations, and other items can change at any time. These changes can affect the
service given to the product. Obtain the complete and most current information before you start any job.
Caterpillar dealers have the most current information available. For a list of the most current publication
form numbers available, see the Service Manual Contents Microfiche, REG1139F.

FUSE - A component in an electrical circuit that will open the circuit if too much
current flows through it.
REED SWITCH - A switch whose contacts are controlled by a magnet. A magnet
closes the contacts of a normally open reed switch; it opens the contacts of a
normally closed reed switch.
SENDER - A component that is used with a temperature or pressure gauge. The
sender measures the temperature or pressure. Its resistance changes to give an
indication to the gauge of the temperature or pressure.
RELAY (Magnetic Switch) - A relay is an electrical component that is activated by
electricity. It has a coil that makes an electromagnet when current flows through it.
The electromagnet can open or close the switch part of the relay.
CIRCUIT BREAKER (C/B) - A component in an electrical circuit that will open the
circuit if too much current flows through it. This does not destroy the circuit breaker
and it can be reset to become part of the circuit again.
SOLENOID - A solenoid is an electrical component that is activated by electricity.
It has a coil that makes an electromagnet when current flows through it. The
electromagnet can open or close a valve or move a piece of metal that can do work.

The circle indicates that the component has screw terminals and a wire can be disconnected
from it.
No circle indicates that the wire cannot be disconnected from the component.
This indicates that the component has a wire connected to it that is connected to ground.
This indicates that the component does not have a wire connected to ground. It is grounded
by being fastened to the machine.
