Organic Cleaners

 During preventive maintenance, never use any organic cleaners (alcohol, etc.) other than

those described in the service manual.

 Make sure the room is well ventilated before using any organic cleaner. Use organic

solvents in small amounts to avoid breathing the fumes and becoming nauseous.

 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 part that

generates heat.

 Wash your hands thoroughly after cleaning parts with an organic cleaner to prevent

contamination of food, drinks, etc. which could cause illness.

 Clean the floor completely after accidental spillage to prevent slippery surfaces that could

cause accidents leading to hand or leg injuries. Use dry rags to soak up spills.

Power Plug and Power Cord

 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.

 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 which could cause a fire.

 Inspect the 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.

 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.

 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.

 Make sure that the power cord is grounded (earthed) at the power source with the ground

wire on the plug.

 Connect the power cord directly into the power source. Never use an extension cord.

 When you disconnect the power plug from the power source, always pull on the plug, not

the cable.
