Ricoh G148, Service Manual

Page: 7 / 537

• Always replace a lithium battery on a PCB with the same type of battery prescribed for use on that
board. Replacing a lithium battery with any type other than the one prescribed for use on the board
could lead to an explosion or damage to the PCB.
• Never discard used batteries by mixing them with other trash. Remove them from the work site and
dispose of them in accordance with local laws and regulations regarding the disposal of such items.
Ozone Filters
• Always replace ozone filters as soon as their service life expires (as described in the service manual).
An excessive amount of ozone can build up around machines that use ozone filters if they are not
replaced at the prescribed time.
• The room where the machine is located must be well ventilated. Excessive ozone could cause per-
sonnel working around the machine to feel unwell.
Power Plug and Power Cord
• Before serving 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.
• The machine must be located near its power source. The area around must be free of obstacles so
the power cord can be disconnected 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.
