Safety Information

This chapter presents the following safety information that you need to get familiar with before you service a Lenovo product:

• “General safety”
• “Electrical safety”
• “Safety inspection guide”
•  “Handling devices that are sensitive to electrostatic discharge”
•  “Grounding requirements”
• “Safety notices: multilingual translations”

2.1 General safety

Follow these rules below to ensure general safety:

• Observe a good housekeeping in the area where the machines are put during and after the maintenance.

• When lifting any heavy object:
  1. Make sure that 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 it.
  4. Lift it by standing or pushing up with your leg muscles; this action could avoid the strain from the muscles in your back. Do not attempt to lift any object that weighs more than 16 kg (35 lb) or that you think is too heavy for you.

• Do not perform any action that causes hazards to the customer, or that makes the machine unsafe.

• Before you start the machine, make sure that other service representatives and the customer are not in a hazardous position.

• Place removed covers and other parts in a safe place, keeping them 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 it over.

• Do not wear loose clothing that can be trapped in the moving parts of the machine. Make sure 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 the nonconductive clip, about 8 centimeters (3 inches) from the end.

• Do not wear jewelry, chains, metal-frame eyeglasses, or metal fasteners for your clothing.
  Attention: Metal objects are good electrical conductors.

• Wear safety glasses when you are hammering, drilling, soldering, cutting wire, attaching springs, using solvents, or working in any other conditions that may be hazardous to your eyes.

• After service, reinstall all safety shields, guards, labels, and ground wires. Replace any safety device that is worn or defective.

• Reinstall all covers correctly before returning the machine to the customer.

• Fan louvers on the machine help to prevent the overheating of internal components. Do not obstruct fan louvers or cover them with labels or stickers.

2.2 Electrical safety
Observe the following rules when working on electrical equipments.

Important:
Use only approved tools and test equipments. Some hand tools have handles covered with a soft material that does not insulate you when working with live electrical currents.
Many customers have rubber floor mats near their machines that contain small conductive fibers to decrease electrostatic discharges. Do not use such kind of mat to protect yourself from electrical shock.

• Find the room emergency power-off (EPO) switch for disconnecting the switch or electrical outlet. If an electrical accident occurs, you can then operate the switch or unplug the power cord quickly.

• Do not work alone under hazardous conditions or near the equipment that has hazardous voltages.

• Disconnect all power before:
  — Performing a mechanical inspection
  — Working near power supplies
  — Removing or installing main units

• Before you start to work on the machine, unplug the power cord. If you cannot unplug it, ask the customer to power-off the wall box that supplies power to the machine, and to lock the wall box in the off position.

• If you need to work on a machine that has exposed electrical circuits, observe the following precautions:
  — Ensure that another person, familiar with the power-off controls, is near you.
  Attention: Another person must be there to switch off the power, if necessary.
  — Use only one hand when working with powered-on electrical equipment; keep the other hand in your pocket or behind your back.
  Attention: An electrical shock can occur only when there is a complete circuit. By observing the above rule, you may prevent a current from passing through your body.
  — When using testers, set the controls correctly and use the approved probe leads and accessories for that tester.
  — Stand on suitable rubber mats (obtained locally, if necessary) to insulate you from grounds such as metal floor strips and machine frames. Observe the special safety precautions when you work with very high voltages; instructions for these precautions are in the safety sections of maintenance information. Be extremely careful when you measure the high voltages.

• Regularly inspect and maintain your electrical hand tools for safe operational condition.

• Do not use worn or broken tools and testers.

• Never assume that power has been disconnected from a circuit. First, check it to make sure that it has been powered off.

2.3 Safety inspection guide

The purpose of this inspection guide is to assist you in identifying potential unsafe conditions. As each machine was designed and built, required safety items were installed to protect users and service personnel from injury. This guide addresses only those items. You should use good judgment to identify potential safety hazards according to the attachment of non-Lenovo features or options not covered by this inspection guide.
If any unsafe conditions are present, you must determine how serious the apparent hazard could be and whether you can continue without first correcting the problem.

Consider these conditions and the safety hazards they present:

•  Electrical hazards, especially primary power (primary voltage on the frame can cause serious or fatal electrical shock)
• Explosive hazards, such as a damaged CRT face or a bulging capacitor
• Mechanical hazards, such as loose or missing hardware

To determine whether there are any potential unsafe conditions, use the following checklist at the beginning of every service task. Begin the checks with the power off, and the power cord disconnected. Checklist:

1. Check exterior covers for damage (loose, broken, or sharp edges).

2. Turn off the product. Disconnect the power cord.

3. Check the power cord for:
   a. A third-wire ground connector in good condition. Use a meter to measure third-wire ground continuity for 0.1 ohm or less between the external ground pin and the frame ground.
   b. The power cord should be the type specified in the parts list.
   c. Insulation must not be frayed or worn.

4. Check for cracked or bulging batteries.

5.  Remove the cover.

6.  Check for any obvious non-Lenovo alterations. Use good judgment as to the safety of any nonLenovo alterations.

7.  Check inside the unit  for any obvious unsafe conditions, such  as metal filings, contamination, water or other liquids, or signs of fire or smoke damage.

8.  Check for worn, frayed, or pinched cables.

9.  Check that the  power-supply cover fasteners (screws or rivets) have not  been removed or tampered with.

2.4 Handling devices that are sensitive to electrostatic discharge
Any computer part containing transistors or integrated circuits (ICs) should be considered sensitive to electrostatic discharge (ESD). ESD damage can occur when there is a difference in charge between objects. Protect against ESD damage by equalizing the charge so that the machine, the part, the work mat, and the person handling the part are all at the same charge.

Notes:

1. Use product-specific ESD procedures when they exceed the requirements noted here.
2.  Make sure that the ESD protective devices you use have been certified (ISO 9000) as fully effective.

When handling ESD-sensitive parts:

• Keep the parts in protective packages until they are inserted into the product.
• Avoid contact with other people.
•  Wear a grounded wrist strap against your skin to eliminate static on your body.
•  Prevent the part from touching your clothing. Most clothing is insulative and retains a charge even when you are wearing a wrist strap.
• Use the black side of a grounded work mat to provide a static-free work surface. The mat is especially useful when handling ESD-sensitive devices.
• Select a grounding system, such as those listed below, to provide protection that meets the specific service requirement.

Notes:
The use of a grounding system to guard against ESD damage is desirable but not necessary.

•  Attach the ESD ground clip to any frame ground, ground braid, or green wire ground.
• When working on a double-insulated or battery-operated system, use an ESD common ground or reference point. You can use coax or connector outside shells on these systems.
• Use the round ground prong of the ac plug on ac-operated computers.

2.5 Grounding requirements
Electrical grounding of the computer is required for operator safety and correct system function. Proper grounding of the electrical outlet can be verified by a certified electrician.
2.6 Safety notices multilingual translations
The safety notices in this section are provided in English, French, German, Hebrew, Italian, Japanese, and Spanish.
Safety notice 1
Before the computer is powered on after FRU replacement, make sure all screws, springs, and other small parts are in place and are not left loose inside the computer. Verify this by shaking the computer and listening for rattling sounds. Metallic parts or metal flakes can cause electrical shorts.
