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.   

 

WARNING 

Use of substitute replacement parts, which do not have the same, specified safety characteristics may create shock, 

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.
