Organic Cleaners 
CAUTION 
1.  During preventive maintenance, never use any organic cleaners (alcohol, 
etc.) other than those described in the service manual. (Refer the “2. 
Preventive Maintenance” in the Service Manual.) 
2.  Make sure the room is well ventilated before using any organic cleaner. 
Always use organic solvents in small amounts to avoid breathing the fumes 
and becoming nauseous.  
3.  Switch the machine off, unplug it, and allow it to cool before doing preventive 
maintenance. To avoid fire or explosion, never use an organic cleaner near 
any component that generates heat. 
4.  Wash your hands thoroughly after cleaning parts with an organic cleaner to 
avoid contamination of food, drinks, etc. which could cause illness. 
 
Power Plug and Power Cord 
WARNING 
1.  Before servicing the machine (especially when responding to a service call), 
always make sure that the power plug has been inserted completely into the 
power source. A partially inserted plug could lead to heat generation (due to 
a power surge caused by high resistance) and cause a fire or other problems.
2.  Always check the power plug and make sure that it is free of dust and lint. 
Clean it if necessary. A dirty plug can generate heat and cause a fire. 
3.  Inspect the entire length of the power cord for cuts or other damage. Replace 
the power cord if necessary. A frayed or otherwise damaged power cord can 
cause a short circuit which could lead to a fire or personal injury from 
electrical shock. 
4.  Check the length of the power cord between the machine and power supply. 
Make sure the power cord is not coiled or wrapped around any object such 
as a table leg. Coiling the power cord can cause excessive heat to build up 
and could cause a fire. 
5.  Make sure that the area around the power source is free of obstacles so the 
power cord can be removed quickly in case of an emergency. 
6.  Make sure that the power cord is grounded (earthed) at the power source 
with the ground wire on the plug. 
7.  Connect the power cord directly into the power source. Never use an 
extension cord. 
8.  When you disconnect the power plug from the power source, always pull the 
plug, not the cable.
