During Maintenance
General
• Before you begin a maintenance procedure: 1) Switch the machine off, 2) Disconnect the power plug
from the power source, 3) Allow the machine to cool for at least 10 minutes.
• Avoid touching the components inside the machine that are labeled as hot surfaces.
Safety Devices
• Never remove any safety device unless it requires replacement. Always replace safety devices
immediately.
• Never do any procedure that defeats the function of any safety device. Modification or removal of a
safety device (fuse, switch, etc.) could lead to a fire and personal injury. Always test the operation of
the machine to ensure that it is operating normally and safely after removal and replacement of any
safety device.
• For replacements use only the correct fuses or circuit breakers rated for use with the machine. Using
replacement devices not designed for use with the machine could lead to a fire and personal injuries.
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 contamination of food,
drinks, etc. which could cause illness.
• Clean the floor completely after accidental spillage of silicone oil or other materials to prevent slippery
surfaces that could cause accidents leading to hand or leg injuries. Use “My Ace” Silicone Oil
Remover (or dry rags) to soak up spills. For more details, please refer to Technical Bulletin “Silicone
Oil Removal” (A024-50).
