.  FINDING REQUIRED MAINTENANCE. 

(Refer to Table 2-2)

 

 
 

a.  When the need for preventive maintenance has been 

identified, the operator must turn to the right place to find 
exactly what to do.  
 
 

b.  Each piece of equipment has specific requirements to 

keep it running in peek condition. Because most pieces of 
equipment are different, the operator should check the 
appropriate Technical Manual (TM) for instructions on when and 
how to conduct preventive maintenance. 
 
    c.  Notice from the chart located on pages 10-11, procedures 
are listed on equipment needed to perform the PM. Under the 
“interval” column the operator can find what hour the 
maintenance will be performed at.

.  REMOVING PARTS DURING MAINTENANCE.    

 

    a.  

Removing Parts

. When attempting to remove parts while 

performing maintenance on any mobile electric power piece of 
equipment the following needs to be accomplished: 
 
        (1) Get the TM and go to the Alphabetical Index at the 
back of the TM.  
 
        (2) Look up the item or items that you will be working 
on.   
 
        (3) You Will Find the Removing Steps, for Example: 
  
            (a) Replacing the fuel filter goes to the Index and 
finds operators maintenance.   
 
            (b) Once you have found operators maintenance look 
at the list of repairs that you can do you will find the fuel 
filter and strainer assembly. 
 
            (c) There you are going to have a paragraph number.  

WARNING 

Electrocution Hazard 

 Electrical high voltage cannot be seen but it can kill you, 

render you unconscious, 

or severely burn you. Failure to observe safety precautions 

may result in serious injury or death.
