Important Safety Notice

   

Proper service and repair is important to the safe, reliable operation of all AOC Company Equipment. The service 
procedures recommended by AOC and described in this service manual are effective methods of performing service 
operations. Some of these service operations require the use of tools specially designed for the purpose. The special 
tools should be used when and as recommended.

 

It is important to note that this manual contains various CAUTIONS and NOTICES which should be carefully read in 
order to minimize the risk of personal injury to service personnel. The possibility exists that improper service methods 
may damage the equipment. It is also important to understand that these CAUTIONS and NOTICES ARE NOT 
EXHAUSTIVE. AOC could not possibly know, evaluate and advise the service trade of all conceivable ways in which 
service might be done or of the possible hazardous consequences of each way. Consequently, AOC has not 
undertaken any such broad evaluation. Accordingly, a servicer who uses a service procedure or tool which is not 
recommended by AOC must first satisfy himself thoroughly that neither his safety nor the safe operation of the 
equipment will be jeopardized by the service method selected.   
Hereafter throughout this manual, AOC Company will be referred to as AOC.

fire, or other hazards. 
 
Under no circumstances should the original design be modified or altered without written permission from AOC. AOC 
assumes no liability, express or implied, arising out of any unauthorized modification of design. 
Servicer assumes all liability.
