Before Installation or Maintenance
- Shipping and Moving the Machine -
• Work carefully when lifting or moving the machine. If the machine is heavy, two or more customer
engineers may be required to prevent injuries (muscle strains, spinal injuries, etc.) or damage to the
machine if it is dropped or tipped over.
• Personnel moving or working around the machine should always wear proper clothing and footwear.
Never wear loose fitting clothing or accessories (neckties, loose sweaters, bracelets, etc. ) or casual
footwear (slippers, sandals, etc.) when lifting or moving the machine.
• Always unplug the power cord from the power source before you move the machine. Before you
move the machine, arrange the power cord so it will not fall under the machine.
- Power -
• Always turn the machine off and disconnect the power plug before doing any maintenance procedure.
After turning the machine off, power is still supplied to the main machine and other devices. To prevent
electrical shock, switch the machine off, wait for a few seconds, then unplug the machine from the
power source.
• Before you do any checks or adjustments after turning the machine off, work carefully to avoid injury.
After removing covers or opening the machine to do checks or adjustments, avoid touching electrical
components or moving parts (gears, timing belts, etc.).
• After turning the machine on with any cover removed, keep your hands away from electrical com-
ponents and moving parts. Never touch the cover of the fusing unit, gears, timing belts, etc.
- Installation, Disassembly, and Adjustments -
• After installation, maintenance, or adjustment, always check the operation of the machine to make
sure that it is operating normally. This ensures that all shipping materials, protective materials, wires
and tags, metal brackets, etc., (attached to protect the machine during shipping), have been removed
and that no tools remain inside the machine.
• 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.
