• Never use your fingers to check moving parts that are causing spurious noise. Never use your
fingers to lubricate moving parts while the machine is operating.
Special Tools
• Use only standard tools approved for machine maintenance.
• For special adjustments, use only the special tools and lubricants described in the service manual.
Using tools incorrectly, or using tools that could damage parts, could damage the machine or
cause injuries.
During Maintenance
General
• Before you begin a maintenance procedure always switch the machine off.
• Disconnect the power plug from the power source.
• 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 (a fuse, thermistor, etc.) unless it requires replacement. Always
replace a safety device immediately.
• Never do any procedure that defeats the function of any safety device. Modification or removal of
a safety device (fuse, thermistor, etc.) could cause a fire and personal injury. After removal and
replacement of any safety device, always test the operation of the machine to ensure that it is
operating normally and safely.
• For replacement parts use only the correct fuses, thermistors, circuit breakers, etc. rated for use with
the machine. Using replacement devices not designed for use with the machine could cause a fire
and personal injuries.
