The following section presents safety information with which you need to be familiar before you service a ThinkPad computer. Make sure that you can stand safely without slipping. Distribute the weight of the object equally between your feet. Use a slow lifting force. Never move suddenly or twist when you attempt to lift. 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 object that weighs more than 16 kg 35 lb or that you think is too heavy for you. Make sure that your sleeves are fastened or rolled up above your elbows. If your hair is long, fasten it. Attention: Metal objects are good electrical conductors. Replace any safety device that is worn or defective. Do not obstruct fan louvers or cover them with labels or stickers. Use only approved tools and test equipment. Some hand tools have handles covered with a soft material that does not insulate you when working with live electrical currents.
Many customers have, near their equipment, rubber floor mats that contain small conductive fibers to decrease electrostatic discharges. Do not use this type of mat to protect yourself from electrical shock. If an electrical accident occurs, you can then operate the switch or unplug the power cord quickly.
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. Attention: Another person must be there to switch off the power, if necessary. 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.
Observe the special safety precautions when you work with very high voltages; Instructions for these precautions are in the safety sections of maintenance information.
