During Maintenance - Ricoh G147 Service Manual

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 components 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.
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 -
