Important information about replacing RoHS compliant
FRUs
RoHS, The Restriction of Hazardous Substances in Electrical and Electronic
Equipment Directive (2002/95/EC) is a European Union legal requirement
affecting the global electronics industry. RoHS requirements must be
implemented on Lenovo products placed on the market after June 2006.
Products on the market before June 2006 are not required to have RoHS
compliant parts.

Hardware Maintenance Manual
So, if the parts are not compliant originally, replacement parts can also be
noncompliant, but in all cases, if the parts are compliant, the replacement parts
must also be compliant.
Lenovo plans to transition to RoHS compliance well before the implementation
date and expects its suppliers to be ready to support Lenovo’s requirements
and schedule. Products sold in 2005, will contain some RoHS compliant FRUs.
The following statement pertains to these products and any product Lenovo
produces containing RoHS compliant parts.
RoHS compliant Lenovo IdeaCentre A parts have unique FRU part numbers.
Before or after June, 2006, failed RoHS compliant parts must always be
replaced using RoHS compliant FRUs, so only the FRUs identified as compliant
in the system HMM or direct substitutions for those FRUs can be used.
Note: A direct substitution is a part with a different FRU part number that is
automatically shipped by the distribution center at the time of order.

Chapter 1. About this manual

This chapter contains the safety information that you need to be familiar with
before servicing a computer.
General safety
Follow these rules to ensure general safety:
• Observe good housekeeping in the area of the machines during and after
maintenance.
• When lifting any heavy object:
1. Ensure you can stand safely without slipping.
2. Distribute the weight of the object equally between your feet.
3. Use a slow lifting force. Never move suddenly or twist when you attempt
to lift.
4. Lift by standing or by pushing up with your leg muscles; this action
removes the strain from the muscles in your back. Do not attempt to lift
any objects that weigh more than 16 kg (35 lb) or objects that you think
are too heavy for you.
• Do not perform any action that causes hazards to the customer, or that
makes the equipment unsafe.
• Before you start the machine, ensure that other service representatives and
the customer’s personnel are not in a hazardous position.
• Place removed covers and other parts in a safe place, away from all
personnel, while you are servicing the machine.
• Keep your tool case away from walk areas so that other people will not trip
over it.
• Do not wear loose clothing that can be trapped in the moving parts of a
machine. Ensure that your sleeves are fastened or rolled up above your
elbows. If your hair is long, fasten it.
• Insert the ends of your necktie or scarf inside clothing or fasten it with a
nonconductive clip, approximately 8 centimeters (3 inches) from the end.
• Do not wear jewelry, chains, metal-frame eyeglasses, or metal fasteners for
your clothing.
